[0002] Food processing refers to the processing of grains, feeds, vegetable oils, vegetables, fruits, and nuts directly from agricultural, forestry, animal husbandry, and fishery products. Sterilization is an important part of food safety management. High-temperature steam is one of the commonly used sterilization methods in food processing. Steam sterilization devices are usually used in the high-temperature sterilization process.

[0003] During steam sterilization, a large amount of steam fills the inside of the device. When the device is turned on after sterilization, the steam will liquefy and flow out as liquid, making the area around the device slippery and wasting water resources. In order to address this technical problem, this application proposes a device for steam sterilization of food. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for food steam sterilization. During the sterilization process, the water generated as the steam temperature gradually decreases will fall into a water tank for collection, avoiding direct accumulation on the inner wall of the bottom of the sterilization chamber, which would cause water to flow out directly and make the chamber slippery when the door is opened. After sterilization, the water in the water tank can be pumped back to the water tank for recycling, thus saving water resources.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An apparatus for steam sterilization of food includes a sterilization chamber with a door hinged to its front end.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 An embodiment of this utility model is provided: a device for food steam sterilization, including a sterilization box 1, a door 2 hinged to the front end of the sterilization box 1, a drive motor 3 fixedly connected to the left end of the sterilization box 1, and a rotating shaft 8 rotatably connected to the inner walls of both the left and right ends of the inner wall of the sterilization box 1. The left end of the left rotating shaft 8 is fixedly connected to the drive end of the drive motor 3. A placement component is provided at one end of the rotating shaft 8. The placement component includes a placement box 9 fixedly connected to one end of the rotating shaft 8. A box cover 15 is hinged to the top of the placement box 9. Multiple through holes are opened at the top of both the box cover 15 and the placement box 9. A fixing bolt 16 is threadedly connected to the inner wall of the front end of the box cover 15. The rear side of the outer wall of the fixing bolt 16 is threadedly connected to the inner wall of the front end of the placement box 9.

[0024] Specifically, the drive motor 3 can drive the rotating shaft 8 to rotate during the sterilization process, thereby causing the placement box 9 to rotate inside the sterilization chamber 1. This allows all sides of the food placed inside the placement box 9 to be directly subjected to the steam sterilization effect. During the rotation, the fixing bolt 16 can limit the lid 15, so that the lid 15 can block the food inside the placement box 9 and prevent the food from falling out during the rotation.

[0025] A water tank 12 is provided on the inner wall of the bottom end of the sterilization box 1. A return pipe 6 is provided through the inner wall of the rear end of the water tank 12. A water pump 7 is provided on the outer wall of the return pipe 6. The other end of the return pipe 6 is provided through the rear end of the water tank 5. Fixing rings 10 are fixedly connected to both the left and right ends of the sterilization box 1. A steam pipe 11 is fixedly connected to the inner wall of the fixing ring 10. A number of air holes are provided on the outer wall of the steam pipe 11. The right end of the steam pipe 11 is connected to the water tank 5 through a conveying assembly. The conveying assembly includes an air supply pipe 4 that passes through the right end of the steam pipe 11. The right end of the air supply pipe 4 passes through the left end of the water tank 5. A partition 13 is fixedly connected to the inner wall of the water tank 5. A heating coil 14 is fixedly connected to the inner wall of the water tank 5. The outer wall of the air supply pipe 4 passes through the right end of the sterilization box 1. The air supply pipe 4 is used to transport the steam inside the water tank 5 to the steam pipe 11.

[0026] Specifically, the heating coil 14 inside the water tank 5 heats the water stored inside to generate steam. The generated steam is input into the steam pipe 11 inside the sterilization chamber 1 through the air supply pipe 4, and then sprayed out through the air hole on the steam pipe 11 for sterilization. The steam pipe 11 is installed inside the sterilization chamber 1 by the fixing ring 10. During the sterilization process, the water generated by the gradual decrease of steam temperature will fall into the water tank 12 for collection, avoiding direct accumulation on the inner wall of the bottom of the sterilization chamber 1, which would cause water to flow out directly and make it slippery when the chamber door 2 is opened. After sterilization, the water in the water tank 12 can be pumped back to the water tank 5 by the water pump 7 for recycling, saving water resources.

[0027] Working principle: In actual use, first pull the handle to open the door 2, then open the inner cover 15 of the door 2, put the food to be sterilized into the placement box 9, then close the cover 15 and insert the fixing bolt 16 into the cover 15 and the placement box 9 and rotate it to limit the cover 15 and prevent the food from falling out of the placement box 9 during sterilization. Then close the door 2, start the heating coil 14 in the water tank 5 to heat the water inside the water tank 5, and the steam generated by heating is input into the steam pipe 11 through the air supply pipe 4, and then sprayed out from the air holes on the surface of the steam pipe 11 to sterilize the food. During this process, the drive motor 3 is started at the same time to drive the rotating shaft 8 to rotate, which drives the placement box 9 to rotate inside the sterilization chamber 1, so that all sides of the food can directly contact the steam to ensure the sterilization effect. During the sterilization process, the water droplets condensed by the steam will fall into the water tank 12 for storage. After sterilization, they can be pumped by the water pump 7 to the water tank 5 for recycling to save costs.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
