[0002] In the rapid development of the modern catering industry, restaurants, central kitchens, school cafeterias, and other venues are increasingly reliant on pre-prepared meals. Pre-prepared meals, with their convenience and efficiency, can effectively shorten food preparation time, improve meal service efficiency, and meet large-scale, diversified catering needs.

[0003] However, most pre-prepared food processing equipment on the market is single-function, with sterilization and heating equipment operating independently, requiring companies to configure multiple machines during production. For restaurants, central kitchens, school cafeterias, and small pre-prepared food processing plants, the traditional single-function sterilization and heating equipment not only occupies a lot of space but also increases equipment purchase and maintenance costs. Furthermore, a single heating method is difficult to adapt to different types of pre-prepared foods. For example, high-temperature sterilization of some seafood pre-prepared foods can damage their tender texture, leading to a decline in food quality and affecting the customer's dining experience. On the other hand, a single sterilization method may result in incomplete sterilization, failing to meet the sterilization requirements of different types of pre-prepared foods.

[0028] As shown in Figure 3, the electric heater 4 is installed inside the water storage chamber 101, and is tightly fitted to the inner wall of the water storage chamber 101. The electric heater 4 is used to heat the water in the water storage chamber 101 to generate steam. It provides a heat source for steam generation and works in conjunction with the steam temperature control unit 2 to achieve precise steam control.

[0029] As shown in Figures 1 and 3: The heating sterilization system includes an air circulation component 3, a heating component 6, and steam distribution plates 9. Several steam distribution plates 9 are connected to a steam distribution component 5. The steam distribution component 5 includes a vacuum pump 501 connected to the interior of a water storage chamber 101. A three-way valve 502 is installed on the vacuum pump 501. A gas guide pipe 503 is installed on the three-way valve 502. Several on / off valves 504 are installed on the gas guide pipe 503. The on / off valves 504 are connected to the corresponding steam distribution plates 9 through pipes. Steam is precisely distributed to the steam distribution plates 9 of each heating chamber 102 to achieve steam heating and pasteurization functions.

[0030] As shown in Figures 1 and 3, the air circulation assembly 3 includes an exhaust fan 301 whose air inlet is connected to the heating chamber 102. The exhaust fan 301 is equipped with a return air pipe 302, and the heating chamber 102 is equipped with a distribution air pipe 303. The end of the return air pipe 302 is connected to the distribution air pipe 303. Through these pipe connections, an air circulation channel is formed, allowing the air within the heating chamber 102 to circulate, resulting in more even heating of the pre-cooked food and improved sterilization and heating effects.

[0031] As shown in Figure 3, the heating assembly 6 includes a microwave generator 601 and a far-infrared heating tube 602 embedded in the top of the inner wall of the heating chamber 102. A heat insulation plate is provided between the microwave generator 601 and the far-infrared heating tube 602. A sealed waterproof structure, such as tempered glass, is provided below both the microwave generator 601 and the far-infrared heating tube 602 to ensure the safety and heating effect of the equipment.

[0032] As shown in Figures 1 and 3, a pressure relief valve 10 is also provided on the heating chamber 102. When the air pressure inside the heating chamber 102 is too high, the pressure relief valve 10 will automatically open to release pressure, ensuring the safety of the equipment and operators and preventing equipment damage or safety accidents caused by excessive air pressure.

[0033] Working principle: Processing leafy vegetables in pre-prepared vegetables

[0034] Arrange the pre-cooked leafy vegetables neatly on the shelves, and place them on the shelf trays 8 of the heating chamber 102. Close the chamber door 7. Considering the easy oxidation and nutrient loss of leafy vegetables, select the pasteurization mode and steam reheating mode on the controller of the chamber door 7. Check the water level and air pressure in the water storage chamber 101, and adjust the water level and air pressure to the appropriate range using the electromagnetic air inlet valve and electromagnetic water inlet valve.

[0035] The equipment is started, and the electric heater 4 heats the water in the water storage chamber 101. The steam temperature control unit 2 monitors the water temperature, water level, and air pressure in real time. When the set conditions are met, the vacuum pump 501 adjusts the air pressure inside the water storage chamber 101. Steam is then delivered to the steam distribution plate 9 of the heating chamber 102 via the three-way valve 502, the air guide pipe 503, and the on / off valve 504 to pasteurize and reheat the pre-cooked vegetables. During this process, the exhaust fan 301, the return air pipe 302, and the air distribution pipe 303 of the air circulation component 3 work together to ensure that the heat is evenly distributed in the heating chamber 102, ensuring that the leafy vegetables are heated evenly and avoiding local overheating that could lead to nutrient loss and a deterioration in taste.

[0036] After the preset sterilization and heating times are reached, the equipment automatically stops operating. Open the door 7, remove the prepared food, and check the sterilization and heating effects. Clean the heating chamber 102 and steam distribution plate 9 to keep the equipment clean. Inspect the water storage chamber 101 and replenish water and gas if necessary to prepare for the next use.

[0037] Meat pre-cooking

[0038] Arrange the pre-cooked meat dishes neatly on the shelves, and place them on the shelf trays 8 of the heating chamber 102. Close the chamber door 7. Given the high sterilization requirements of the pre-cooked meat dishes, select the microwave-pasteurization combined mode and the baking reheat mode on the controller. Adjust the position of the shelf trays 8 appropriately according to the packaging and quantity of the pre-cooked dishes to ensure proper placement and to avoid affecting heat transfer.

[0039] Upon startup, the steam generation system produces steam for pasteurization, while the microwave generator 601 activates for microwave sterilization, achieving a combined sterilization effect to ensure thorough sterilization of the pre-prepared meat. After sterilization, the far-infrared heating tube 602 activates for baking and reheating, imparting good color and flavor to the pre-prepared meat. The air circulation component 3 operates continuously to ensure uniform temperature within the heating chamber 102, guaranteeing consistent heating of the pre-prepared meat.

[0040] After processing, turn off the equipment and remove the pre-cooked food. Clean and maintain the equipment, checking that all components are functioning properly, such as the microwave generator 601, the far-infrared heating tube 602, and the sealing performance of the steam distribution assembly 5. Based on the results of this processing, optimize and adjust the parameters for the next similar pre-cooked food processing to further improve processing quality and efficiency.
