In the vast world of cooking, fried food has always occupied a popular place with its unique crispy taste and rich aroma. From the mouth-watering snack stalls on the streets to the carefully crafted dishes in high-end restaurants, fried food is everywhere. Among the many deep-frying cooking equipment, the gas pressure fryer is like a bright new star, gradually emerging. With its excellent performance and unique cooking method, it brings unprecedented cooking experience to chefs and presents amazing delicious dishes to food lovers.
1. Working principle of gas pressure fryer
The working principle of gas pressure fryer combines the dual advantages of pressure cooking and traditional frying, which can be called a clever innovation in the field of cooking technology. To understand its working mechanism, we might as well start with the basic principle of pressure cooking. Everyone must be familiar with pressure cookers. Pressure cookers seal the space inside the pot. During the heating process, the water in the pot is continuously vaporized into water vapor. Since the steam cannot escape, the air pressure in the pot will continue to rise. According to the principles of physics, the increase in air pressure will increase the boiling point of water accordingly. Under normal circumstances, water boils at 100℃, but in a pressure cooker, the boiling point of water can be raised to 120℃ or even higher. In this way, food can be cooked quickly under high temperature and high pressure, greatly shortening the cooking time. This is the core of pressure cooking.
The gas pressure fryer draws on this principle and perfectly combines it with deep frying cooking. Structurally, it is equipped with a large-capacity oil tank for holding sufficient cooking oil, and has a flip-top lid with excellent sealing. When we put the prepared ingredients into the frying basket and put the frying basket into the oil tank, we close the lid and start the cooking journey. At this time, the gas burner starts working, releasing powerful heat to quickly heat the cooking oil in the oil tank. As the oil temperature continues to rise, the oil around the ingredients begins to play a key role. Because the lid is closed, a relatively closed high-pressure environment is formed in the pot, just like a pressure cooker, and the air pressure in the pot gradually increases. Under the dual effects of high temperature and high pressure, the cooking process of the ingredients is greatly accelerated.
Compared with ordinary frying methods, gas pressure fryers have significant advantages. In ordinary frying, the ingredients are cooked only by the temperature of the hot oil, and the heat transfer is relatively simple. Under standard atmospheric pressure, although the oil temperature can reach a high level, the moisture inside the ingredients is easy to lose quickly under high temperature, resulting in a dry taste. The high-pressure environment in the gas pressure fryer allows heat to penetrate into the ingredients more quickly and evenly, which not only greatly shortens the cooking time, but also effectively locks the moisture of the ingredients themselves. Take fried chicken as an example. The fried chicken cooked in the gas pressure fryer has a pleasant golden and crispy texture on the outside, while the chicken inside is tender and juicy. Every bite is full of rich meaty aroma and rich juice, with distinct taste layers, which is endless. This unique cooking effect is a vivid embodiment of the charm of the gas pressure fryer.
2. Structural analysis of the gas pressure fryer
(I) Heating system
The heating system of the gas pressure fryer can be called its "power heart" and plays a decisive role in the cooking effect. At present, the heating system of gas pressure fryers on the market mainly uses two types of gas, namely natural gas and liquefied petroleum gas (LPG). These two types of gas have their own characteristics, providing users with a variety of choices.
As a clean and efficient energy source, natural gas has the advantage of relatively low cost. In some areas with a well-developed natural gas supply network, the use of natural gas-driven gas pressure fryers can effectively reduce long-term operating costs. Its combustion process is relatively stable, and it can continuously provide uniform and strong heat to the fryer, so that the oil temperature in the oil tank rises rapidly and remains within the precise set range. For example, in large restaurants or chain catering companies, natural gas-driven gas pressure fryers can meet high-intensity and large-scale cooking needs, ensuring that each batch of fried food can be cooked under stable temperature conditions, ensuring the consistency of the quality of the dishes.
Liquefied petroleum gas stands out for its portability and high energy density. For some places that cannot access natural gas pipelines, such as mobile food trucks, temporary food stalls or catering stores in some remote areas, liquefied petroleum gas has become an ideal energy choice. It is easy to store, and only needs to be equipped with corresponding gas tanks to provide sufficient power for gas pressure fryers anytime and anywhere. Moreover, liquefied petroleum gas can release a lot of heat instantly when burning, so that the fryer can reach a high temperature in a short time, which is particularly suitable for catering scenes that need to serve food quickly. For example, in busy street food stalls, stall owners use gas pressure fryers driven by liquefied petroleum gas to quickly fry delicious French fries, chicken wings and other snacks for customers, efficiently meeting customer needs.
In terms of burner design, gas pressure fryers of different brands and models have their own unique features, but they are all committed to achieving efficient and uniform heating effects. Common types of burners include tubular burners and cast iron burners. Tubular burners are usually composed of multiple slender pipes. The gas is fully burned in the pipes, and the flames are evenly distributed along the pipes. It can heat the bottom of the oil tank over a large area, so that the oil temperature rises quickly and evenly. This burner has a compact structure and high thermal efficiency, which can effectively reduce energy waste. Cast iron burners are known for their durability and excellent thermal conductivity. Cast iron materials can quickly absorb the heat generated by gas combustion and transfer it evenly to the oil tank, making the oil temperature more stable. Even during long-term, high-intensity use, the cast iron burner can maintain good working condition, providing reliable guarantee for the stable operation of the fryer.
(II) Pressure control system
The pressure control system is the key guarantee for the safe and efficient operation of the gas pressure fryer, just like the calibration device in the precision instrument, ensuring that everything is under precise control. Its core components include safety valves, pressure sensors and pressure regulating devices, which work together to maintain the stability of the pressure in the pot.
The safety valve can be called the "loyal guard" in the pressure control system, shouldering a vital safety mission. Its design is extremely sophisticated, usually installed in a conspicuous position on the top or side of the fryer for easy daily inspection and maintenance. When the pressure in the pot rises sharply due to various reasons (such as excessive heating, poor exhaust, etc.), exceeding the preset safety pressure threshold of the equipment, the safety valve will quickly open automatically. At this time, the high-pressure gas in the pot will be discharged in an orderly manner through the exhaust channel of the safety valve, thereby effectively reducing the pressure in the pot and avoiding safety accidents caused by excessive pressure, such as explosion of the fryer and other serious consequences. This automatic protection mechanism of the safety valve provides users with a solid and reliable safety line, allowing people to enjoy the fun of cooking without worries.
The pressure sensor is like a "sensitive sensor" of the pressure control system, closely monitoring the subtle changes in the pressure in the pot at all times. It uses advanced sensing technology to accurately convert the real-time pressure value in the pot into an electrical signal and quickly transmit it to the control system connected to it. Once the pressure value deviates from the preset normal range, the control system will respond immediately. For example, when the pressure sensor detects that the pressure in the pot is lower than the set cooking pressure, the control system will automatically issue a command to increase the gas supply and increase the firepower of the burner to return the pressure in the pot to a normal level; conversely, if the pressure is too high, the control system will take corresponding measures, such as reducing the gas supply and properly opening the exhaust device, to ensure that the pressure is stable in the appropriate range. This real-time and accurate pressure monitoring and control function not only ensures the safety of the cooking process, but also provides a strong guarantee for the cooking quality of food, so that every cooking can be carried out under the most suitable pressure conditions.
The pressure regulating device is a "communication bridge" between the user and the pressure control system. Through it, the user can flexibly and conveniently adjust the pressure in the pot according to the cooking needs of different ingredients. Common pressure regulating devices have two operating modes: knob type and button type. The knob type regulating device is simple and intuitive to operate. The user only needs to gently turn the knob to change the opening of the pressure regulating valve through the mechanical transmission device, thereby achieving precise adjustment of the pressure in the pot. The button type regulating device is more modern and technological, and is usually equipped with an LCD display that can clearly display the current pressure value in the pot and the preset pressure value. The user can easily complete the setting and adjustment of the pressure by pressing the corresponding button. The operation process is clear at a glance and convenient. Regardless of the operation mode, the pressure regulating device provides users with a personalized cooking experience and meets the diverse needs of different dishes for pressure conditions.
(III) Frying basket and liner
As key components that directly contact the ingredients, the material and design of the frying basket and liner have a profound impact on the quality and cooking efficiency of fried foods. In terms of material selection, high-quality gas pressure fryers usually use safe, durable and thermally conductive materials such as 304 stainless steel or food-grade aluminum alloy.
304 stainless steel is highly favored for its excellent corrosion resistance and high temperature resistance. In a high-temperature hot oil environment, 304 stainless steel can maintain stable physical and chemical properties for a long time, and will not produce harmful substances due to chemical reactions with oils and ingredients, ensuring the safety and health of fried foods. At the same time, its good thermal conductivity can quickly and evenly transfer heat to the surface of the ingredients, so that the ingredients are heated evenly in a short time, and the fried food is golden in color and crispy in taste. 304 stainless steel is sturdy and durable, not easy to deform, and can maintain a good use state even under frequent use and high-intensity working conditions, greatly extending the service life of the frying basket and liner.
Food-grade aluminum alloy is also an ideal material choice. Aluminum alloy has the remarkable characteristics of light weight and fast heat conduction. Compared with stainless steel, the frying basket and liner made of aluminum alloy are lighter, easier for users to take and operate, and reduce labor intensity. Its excellent thermal conductivity can quickly conduct the oil temperature to every corner of the food, greatly improving the cooking efficiency. Moreover, after special treatment, a dense oxide film is formed on the surface of food-grade aluminum alloy, which can effectively prevent the precipitation of aluminum elements and ensure the safety of contact with food. In some catering places that pursue efficient cooking and convenient operation, frying baskets and inner pots made of food-grade aluminum alloy have been widely used.
In terms of design, the shape and structural design of the frying basket fully consider the placement of ingredients and the uniform distribution of heat. Common frying baskets adopt a grid-like or hollow design, which can make the hot oil wrap the ingredients in all directions, ensuring that all parts of the ingredients can be fully heated and fried evenly. At the same time, the size of the grid or hollow is carefully calculated, which can not only prevent small pieces of food from falling, but also ensure the smooth flow of oil, so that the oil smoke and residue in the frying process can be discharged in time, keep the oil clean, and extend the service life of the oil. Some frying baskets are also equipped with a handle for easy lifting. The handle is usually made of heat-insulating material. Even when the frying basket is at high temperature, the user can easily and safely remove the frying basket from the inner pot, which is convenient and safe to operate.
The design of the inner pot is also unique. The depth and capacity of the inner pot are reasonably planned according to the overall specifications of the fryer and the target usage scenario. Generally speaking, the inner pot capacity of a commercial gas pressure fryer is large, which can meet the needs of frying a large number of ingredients at the same time and improve the efficiency of serving. The bottom of the inner pot is usually designed to be slightly inclined, which helps the residues generated during the frying process to automatically gather in a specific area for easy cleaning. At the same time, some inner pots are also equipped with guide grooves or spoilers inside, which can optimize the flow path of hot oil in the pot, make the oil temperature more uniform, and further improve the quality of fried food.
III. Advantages of gas pressure fryers
(I) Efficient and fast cooking experience
In the fast-paced modern life, time is money, especially for the catering industry. With its amazing efficient and fast cooking ability, the gas pressure fryer has become a powerful assistant for many catering practitioners, which can significantly improve the speed of serving and meet the growing demand for fast meals for customers.
When we walk into a busy fast food restaurant, there is a constant stream of customers in the store, and the sound of ordering and cooking in the kitchen are intertwined. At this time, the gas pressure fryer has played its great advantage. Compared with traditional frying equipment, the gas pressure fryer can cook the ingredients in a very short time. Take fried chicken nuggets as an example. It may take 15-20 minutes to fry the chicken until it is golden and crispy in an ordinary fryer, but in the gas pressure fryer, this process only takes 5-8 minutes. This is because the high temperature and high pressure environment inside the gas pressure fryer can quickly and evenly penetrate the heat into the ingredients, greatly accelerating the cooking process.
This efficient cooking speed is particularly important during peak hours. Suppose a fast food restaurant needs to serve 100 customers per hour during the lunch peak, and on average each customer orders a set meal containing fried foods such as fried chicken nuggets and French fries. If traditional frying equipment is used, due to the long cooking time, it may require multiple chefs to operate multiple equipment at the same time to barely meet the demand for food delivery, and it is also easy for customers to wait too long and food to be supplied in time. After the introduction of the gas pressure fryer, one device can complete more batches of food cooking in the same time, greatly reducing the workload of the chef, while ensuring that every customer can get a steaming, delicious meal in the shortest time. This efficient and fast food delivery capability not only improves customer satisfaction, but also wins a good reputation for the restaurant, attracting more customers to dine, thereby directly improving the economic benefits of the restaurant.
(II) Excellent food quality assurance
While improving cooking efficiency, the gas pressure fryer has not lowered the requirements for food quality at all. On the contrary, with its unique cooking method, it brings amazing taste and appearance to fried foods, becoming a "secret weapon" to ensure food quality.
In terms of taste, the gas pressure fryer can perfectly achieve the excellent effect of crispy outside and tender inside. When the ingredients are put into the fryer, under the action of high temperature and high pressure, the moisture on the surface of the ingredients quickly vaporizes, forming a crispy shell, just like putting on a "golden armor" for the ingredients. At the same time, the moisture inside the ingredients is effectively locked, keeping the inside tender and juicy. Take fried chicken wings as an example. The chicken wings cooked in a gas pressure fryer have a golden and crispy skin. When you bite it gently, you can hear a crisp "click" sound, as if playing a delicious piece of music. After biting the skin, the tender and juicy chicken inside instantly spreads in your mouth, and the rich meaty aroma and tender taste blend with each other, making people intoxicated. This contrast of crispy outside and tender inside is difficult to achieve with ordinary frying methods, bringing diners the ultimate taste enjoyment.
In terms of appearance, the gas pressure fryer also performs well. Due to the uniform pressure and temperature distribution inside the fryer, the ingredients can be evenly heated during the frying process, so that the fried food has a consistent color and is golden and attractive. Whether it is French fries, fried chicken legs or other fried foods, they can present a mouth-watering perfect color. This beautiful appearance not only stimulates the appetite of customers, but also adds a lot to the restaurant's dishes, enhancing the restaurant's overall image and competitiveness. When the golden and fragrant fried food is served on the table, customers' eyes are immediately attracted and they can't wait to taste it, which undoubtedly adds a lot to the dining experience of the restaurant.
(III) Significant energy-saving advantages
Today, with energy becoming increasingly tight and environmental awareness increasing, energy saving has become an important factor that cannot be ignored in the development and use of various equipment. Gas pressure fryers are excellent in energy saving. Compared with traditional frying equipment, they can save users a lot of energy costs and also make positive contributions to environmental protection.
From the perspective of energy efficiency, gas pressure fryers have obvious advantages. The high-pressure environment inside allows food to be cooked quickly at a relatively low oil temperature, which means that under the premise of achieving the same cooking effect, the gas pressure fryer requires a shorter heating time and consumes less gas. Taking frying a batch of food of the same weight as an example, a traditional deep fryer may need to heat the oil temperature to 180℃ - 200℃ and continue heating for 15 - 20 minutes to complete the cooking, while a gas pressure fryer only needs to heat the oil temperature to 150℃ - 160℃ and complete it within 5 - 8 minutes. Through simple calculations, it can be found that the gas pressure fryer can save about 30% - 50% of gas consumption in this process.
The closed design of the gas pressure fryer further improves energy efficiency. Due to the good sealing performance of the pot lid, the heat in the pot will hardly be dissipated to the external environment during the cooking process, forming an efficient heat circulation system. This not only reduces energy waste, but also enables the fryer to reach and maintain the set temperature faster, thereby further shortening the cooking time and reducing energy consumption.
(IV) Wide range of applicable ingredients
The gas pressure fryer has demonstrated a wide range of food applicability with its powerful performance and flexible cooking methods. Whether it is meat, seafood, vegetables, pastries or other ingredients, they can all be uniquely delicious in the gas pressure fryer, providing a wide space for chefs' creative cooking.
In terms of cooking meat ingredients, the gas pressure fryer is a must. Whether it is tender and juicy chicken, mellow pork, or firm beef, they can all be perfectly cooked in the fryer. Take fried chicken as an example. Whether it is a whole chicken, chicken legs, chicken wings or chicken breast, after being processed in the gas pressure fryer, they can all present an excellent taste of golden and crispy skin and tender and juicy inside. Fried pork products, such as pork chops and fried meatballs, are also delicious. The fat of pork is partially forced out under high temperature and high pressure, making the taste more tender and not greasy. For beef, the gas pressure fryer can fry the steak until it is crispy on the outside and tender on the inside, retaining the original flavor of the beef, and every bite is full of rich meaty aroma.
Seafood ingredients can also shine in gas pressure fryers. After frying, the shell of fresh shrimp becomes crispy and delicious, and can be eaten directly with the shell. The shrimp meat maintains a fresh and smooth taste, and the delicious taste is endless. Fried fish is also a common delicacy. Whether it is the delicate meat of sea bass and cod, or the basa fish with few bones and more meat, it can be fried golden and crispy in the gas pressure fryer. The fish meat is tender and juicy, and paired with special sauces, the taste is unique. In addition, seafood ingredients such as squid and shellfish can also be made into unique delicacies by gas pressure fryers.
The performance of vegetable ingredients in gas pressure fryers is also surprising. In traditional concepts, vegetables are mostly used for stir-frying, cold salad or boiling, but under the magical effect of gas pressure fryers, vegetables can also be transformed into delicious fried delicacies. For example, French fries, as a classic snack loved by the public, can be fried crispy on the outside and tender on the inside in a gas pressure fryer, and the sweetness and crispy taste of potatoes are perfectly combined. Fried onion rings present a unique shape and taste. The spicy taste of onions is alleviated to a certain extent during the frying process, becoming more sweet and delicious, and the golden skin adds an attractive color. There are also vegetables such as zucchini and eggplant, which are coated with batter and fried in a gas pressure fryer. They not only taste crispy, but also lock in the nutrition and sweetness of the vegetables themselves.
Gas pressure fryers are also very good at cooking pastry ingredients. Traditional fried pasta such as fried dough sticks and twisted dough sticks can expand quickly in a gas pressure fryer and become fluffy and crispy. Due to the short frying time, the water loss inside the dough is less, and it tastes softer and chewier. Some special pastries, such as pumpkin cakes and bean paste cakes, are processed by gas pressure fryers, with crispy crusts, soft and sweet fillings, and rich taste. Even foods that originally need to be baked, such as pizza and pies, can be tried in gas pressure fryers, which can bring a different flavor experience.
This wide range of food applicability has greatly expanded the chefs' cooking ideas and innovation space for dishes. Restaurants can use gas pressure fryers to develop a variety of fried dishes according to different seasons, regional characteristics and customer taste needs. For example, in the summer, a refreshing fried vegetable salad is launched, and the fried vegetables are paired with fresh lettuce, tomatoes, etc., and topped with a special salad dressing, which not only satisfies diners' love for fried foods, but also adds a refreshing taste; in the winter, a steaming hot fried meatball soup can be launched, and the fried meatballs are placed in a carefully boiled broth and paired with vegetables, which is warm and delicious. By continuously innovating dishes, restaurants can attract more customers and enhance their market competitiveness.
4. Key points for purchasing gas pressure fryers
(I) Consideration of capacity and power
When purchasing a gas pressure fryer, capacity and power are the first factors that need to be considered, and they are directly related to whether the equipment can meet actual usage needs. For commercial catering places, if it is a small or medium-sized restaurant or fast food restaurant, the daily customer flow is relatively stable and the amount of food served is not particularly large, you can choose a gas pressure fryer with a capacity of about 10-20 liters. This capacity fryer can fry the right amount of ingredients at a time, which can not only ensure the speed of serving food, but also will not cause waste of energy and space. For example, a small fried chicken shop receives about 200-300 customers every day, and a 15-liter gas pressure fryer can meet its daily fried chicken production needs, and can also cope with it relatively easily during peak hours.
For large restaurants, chain catering companies or canteens, due to the large number of diners and the large amount of food served, it is necessary to choose a larger capacity fryer, such as a model with a capacity of more than 30 liters or even higher. A large-capacity fryer can fry more ingredients at a time, greatly improving cooking efficiency and reducing customer waiting time. Like the school cafeteria, which provides meals for hundreds of students every day, a 40-liter gas pressure fryer can fry a large amount of French fries, chicken nuggets and other foods in a short time to meet the students' dining needs.
In terms of power, the power of the gas pressure fryer is closely related to the heating speed and energy consumption. Generally speaking, the greater the power, the faster the heating speed, and the faster the oil temperature can be raised to the set temperature, which is suitable for places with high requirements for the speed of serving meals. But at the same time, high power also means relatively high energy consumption. Therefore, when choosing power, the actual usage scenario and energy cost should be considered comprehensively. For fast food restaurants, snack stands, etc. that need to serve meals frequently and quickly, a gas pressure fryer with a power of about 15-20 kilowatts can be selected. Such power can ensure that the oil temperature rises quickly and meets customer needs in a timely manner; and for some catering places that are not particularly urgent for the speed of serving meals and focus on energy saving, a model with a power of 10-15 kilowatts can be selected to reduce energy costs while ensuring a certain cooking efficiency.
(II) Control of materials and quality
The material and quality of the equipment directly affect the service life, safety and hygienic quality of the gas pressure fryer, so it must be strictly controlled when purchasing. As mentioned earlier, the frying basket and the inner pot are parts that are in direct contact with the food, and their materials must be selected from food-grade high-quality materials, such as 304 stainless steel or food-grade aluminum alloy. When selecting, you can carefully observe the surface of the frying basket and the inner pot. The surface of high-quality materials is smooth and flat, without scratches or burrs, will not damage the food, and is also easy to clean. At the same time, touch it with your hands to feel its thickness. Parts with moderate and uniform thickness are more durable and can withstand high temperatures and frequent use.
In addition to the frying basket and the inner pot, the shell material of the gas pressure fryer cannot be ignored. The shell is usually made of stainless steel or high-strength engineering plastics. The stainless steel shell has the advantages of corrosion resistance, easy cleaning, and beautiful appearance. It can maintain a good appearance and performance for a long time in the humid and fume-rich environment of the kitchen; the high-strength engineering plastic shell has the characteristics of light weight and low cost, and some high-quality engineering plastic shells have good high temperature resistance and impact resistance. When purchasing, you should pay attention to check the workmanship quality of the shell to see if there are cracks, deformations, etc., to ensure that the shell can effectively protect the internal components and ensure safety during use.
In addition, pay attention to the overall quality and process level of the equipment. You can check the manufacturer's qualifications and product certification of the equipment, such as whether it has passed the relevant quality certification, safety certification, etc. Products with a good reputation and formal certification are more guaranteed in terms of quality and after-sales service. You can also actually operate the equipment to check whether the connections of various components are tight, whether the operation of switches and valves is flexible and smooth, whether the burner ignition is fast and stable, whether the pressure control system is sensitive and accurate, etc., and judge the quality of the equipment through these details.
(III) The importance of brand and after-sales service
Choosing a well-known brand of gas pressure fryer is an important guarantee to ensure the quality of the equipment and the use experience. Well-known brands usually have more advanced production technology, stricter quality control system and more complete R&D capabilities. They have been tested for a long time in the market and have accumulated a good reputation. The quality and performance of their products are relatively more stable and reliable.
At the same time, perfect after-sales service is also a factor that needs to be considered when purchasing a gas pressure fryer. It is inevitable that some faults or problems will occur in the use of catering equipment. Good after-sales service can solve these problems for users in time and ensure the normal operation of the equipment. When purchasing, it is necessary to understand the manufacturer's after-sales service policy, including warranty period, maintenance service response time, whether on-site maintenance service is provided, whether there is sufficient supply of accessories, etc. Choose a brand with a wide distribution of after-sales service outlets, quick response, and good service attitude. When the equipment fails, it can get repairs and support from professionals in the first time, reduce equipment downtime, and reduce the impact on catering operations. Some manufacturers also provide value-added services such as equipment installation and commissioning, operator training, etc. These services can help users better use and maintain the equipment and improve the efficiency and life of the equipment.

Ensure that the installation environment of the gas pressure fryer is safe and reliable. The fryer should be placed in a stable, dry, well-ventilated place, away from flammable, explosive items and water sources. During installation, the connection of the gas pipeline must be firm and reliable, use dedicated gas pipelines and joints, and regularly check whether the pipeline has leaks. You can use soapy water to apply to the pipeline interface. If bubbles appear, it means that there is a gas leak. The gas valve should be closed immediately and a professional should be contacted for repair.
During operation, strictly follow the correct steps. When adding cooking oil, the oil level cannot exceed two-thirds of the height of the frying basket to avoid oil overflow during heating and cause a fire. Before closing the lid, make sure that the frying basket is placed correctly and there is no debris in the pot. When turning on the equipment, open the gas valve first, then start the ignition device, and observe whether the burner ignites normally and whether the flame is stable. During cooking, it is strictly forbidden to open the lid without authorization to prevent high-temperature and high-pressure oil vapor from spraying out and causing burns. If any abnormality is found in the equipment, such as excessive pressure, abnormal oil temperature, gas leakage, etc., the gas valve and equipment power supply should be turned off immediately, and professional maintenance personnel should be contacted in time for processing.
After use, turn off the gas valve first, and wait until the oil temperature drops to room temperature before cleaning and storing. When cleaning, be careful to avoid water entering the electrical components and gas pipelines to prevent short circuits or gas leaks.
(II) Daily cleaning and maintenance
Daily cleaning and maintenance are key measures to extend the service life of gas pressure fryers and maintain equipment performance and hygiene. After each use, wait for the oil temperature to cool down, take out the frying basket in time, and pour out the remaining oil in the pot. You can use a filter to filter the remaining oil, remove the residue, and store the filtered oil in a clean container for next use. But be careful not to use cooking oil too many times to avoid affecting the taste and health of the food.
Then, clean the frying basket and liner. You can use a mild detergent and a soft cloth or sponge to wipe to remove the oil and food residue on the surface. Avoid using hard cleaning tools such as steel wool to avoid scratching the surface of the frying basket and liner, affecting their service life and hygiene. For stubborn oil stains, soak the detergent for a period of time before cleaning. After cleaning, rinse with clean water and wipe dry to prevent rust.
The exterior of the equipment, including the outer shell, control panel and other parts, should also be cleaned regularly. Wipe the surface with a clean damp cloth to remove dust and oil. Avoid getting the control panel wet to prevent damage to electrical components. Also check the various parts of the equipment regularly, such as safety valves, pressure sensors, burners, etc., to see if they are loose, damaged or blocked, and make adjustments and repairs in time. According to the requirements of the equipment manual, calibrate the pressure control system regularly to ensure the accuracy of its pressure monitoring and regulation.
Whether it is a catering practitioner who pursues efficient food delivery or a food lover who loves cooking, the gas pressure fryer can bring you a new cooking experience and delicious enjoyment. In practical applications, as long as it is purchased correctly, used safely and maintained carefully, the gas pressure fryer will surely become your right-hand man on the cooking road and create more amazing food miracles for you.
