Abstract
Description
Technical Field
[0001] This invention relates to the field of food processing technology, specifically to a food sterilizer for food processing. Background Technology
[0002] Food is highly susceptible to contamination and spoilage during production, storage, transportation, and sales. Conventional techniques such as high temperature, drying, blanching, pasteurization, freezing, and preservatives can be used to kill insects, sterilize, and preserve food. However, these methods often affect the original flavor and nutritional components of the food. Microwave sterilization, on the other hand, subjects microorganisms in food to both the thermal and non-thermal effects of microwaves, causing mutations in their proteins and physiological substances. This leads to delayed growth and development and eventual death of the microorganisms, achieving the purpose of sterilization and preservation. Microwave sterilization equipment is also used in the sterilization process of jujube pie production. According to a microwave sterilization device for food processing with application number 2023227155335, the device first places materials onto a conveyor belt and feeds them into a microwave heating chamber. The microwave heating chamber is connected to a microwave generator, which emits microwaves to perform low-temperature drying and sterilization on the materials in the heating chamber. Because the microwave generator is made of metal, which has excellent microwave reflection properties, the microwaves are reflected internally, thereby improving the sterilization effect. A first microwave suppressor and a second microwave suppressor are installed on both sides of the microwave heating chamber to prevent microwave radiation leakage. However, during the feeding and conveying of food, the food tends to pile up, causing overlap and reducing the effectiveness of microwave sterilization. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a food sterilization machine for food processing, which solves the problems mentioned in the background section.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a food sterilization machine for food processing, comprising a microwave conveyor, a microwave box mounted on the top of the microwave conveyor, a feeding box mounted on the top of the microwave conveyor and in front of the microwave box, a discharging box mounted on the top of the microwave conveyor and behind the microwave box, two columns fixedly connected to both sides of the microwave conveyor and in front of the feeding boxes, each column having a movable column slidably connected inside, the top of each movable column extending above the column, a top plate fixedly connected to the top of the two movable columns, a limit plate fixedly connected to the bottom of the top plate, the limit plate being located above the microwave conveyor, and a fixing frame fixedly connected to the bottom of the microwave conveyor.
[0005] Preferably, each of the columns has a threaded groove on its surface, and each of the threaded grooves has a screw threaded into it. Each of the movable columns has a plurality of insertion holes on its surface, and one end of each screw extends into the corresponding insertion hole and into the positioning groove opened on the inner wall of the column.
[0006] Preferably, a scale is fixedly connected to the bottom of both ends of the top plate, the scale is located in front of the column, and a pointer block is fixedly connected to the surface of the column.
[0007] Preferably, electric telescopic rods are fixedly connected to both sides of the microwave conveyor, and connectors are fixedly connected to the telescopic ends of the two electric telescopic rods. A back plate is fixedly connected between the two connectors and at the front end of the microwave conveyor.
[0008] Preferably, the top of the microwave conveyor and the inner side of the connector are fixedly connected to a side plate.
[0009] Preferably, a fixing block is fixedly connected to both sides of the microwave conveyor and in front of the electric telescopic rod. A guide post is fixedly connected to the top of each fixing block. A guide rod is slidably connected inside each guide post. The top of each guide rod extends to the top of the guide post and is fixedly connected to the bottom of the connector. A dehumidification pipe is installed on the microwave box.
[0010] This invention provides a food sterilization machine for food processing, which has the following beneficial effects:
[0011] 1. This food sterilization machine for food processing is equipped with columns, a top plate, and a limiting plate. The position of the limiting plate is adjusted according to the height of the food when it is placed. When the conveyor belt on the microwave conveyor moves the food, the height between the limiting plate and the conveyor belt on the microwave conveyor can only accommodate one food item when the stacked food passes under the limiting plate. The food stacked on top of the food is pushed to the surface of the conveyor belt of the microwave conveyor, preventing the food from stacking together and affecting the sterilization effect of the microwave generator inside the microwave chamber on the surface of the conveyor belt of the microwave conveyor.
[0012] 2. This food sterilization machine for food processing is equipped with side plates, a back plate, and an electric telescopic rod. The left and right side plates and the front back plate prevent food from falling from the sides and front of the microwave conveyor when the limiting plate pushes the stacked food, thereby preventing accidental damage to the food.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] Example 1
[0021] Please see Figures 1 to 5 The present invention provides a technical solution: a food sterilization machine for food processing, including a microwave conveyor 1, a microwave box 19 installed on the top of the microwave conveyor 1, a feeding box 18 installed on the top of the microwave conveyor 1 and in front of the microwave box 19, a discharging box 20 installed on the top of the microwave conveyor 1 and behind the microwave box 19, two columns 2 fixedly connected to both sides of the microwave conveyor 1 and in front of the feeding box 18, each column 2 having a movable column 23 slidably connected inside, the top of each movable column 23 extending above the column 2, a top plate 9 fixedly connected to the top of the two movable columns 23, a limiting plate 10 fixedly connected to the bottom of the top plate 9, the limiting plate 10 being located above the microwave conveyor 1, and a fixing frame 22 fixedly connected to the bottom of the microwave conveyor 1.
[0022] The surface of the column 2 is provided with threaded grooves 6, and screws 5 are threadedly connected inside the threaded grooves 6. The surface of the movable column 23 is provided with several insertion holes 3. One end of each screw 5 extends into the corresponding insertion hole 3 and into the positioning groove 4 opened on the inner wall of the column 2. One end of the screw 5 can pass through the insertion hole 3 and be inserted into the positioning groove 4 to limit and fix the position of the movable column 23.
[0023] A scale 7 is fixedly connected to the bottom of both ends of the top plate 9. The scale 7 is located in front of the column 2. A pointer block 8 is fixedly connected to the surface of the column 2. When the top plate 9, the limiting plate 10, and the moving column 23 move, the moving column 23 drives the scale 7 to move upward. The height of the limiting plate 10 can be obtained by observing the scale on the surface of the scale 7 pointed to by one end of the pointer block 8.
[0024] Electric telescopic rods 12 are fixedly connected to both sides of the microwave conveyor 1. Connectors 13 are fixedly connected to the telescopic ends of the two electric telescopic rods 12. A back plate 14 is fixedly connected between the two connectors 13 and at the front end of the microwave conveyor 1, so that the position of the back plate 14 can be adjusted.
[0025] Side plates 11 are fixedly connected to the top of the microwave conveyor 1 and to the inside of the connector 13. The two side plates 11 and the back plate 14 at the front end prevent the food from falling from the sides and front end of the microwave conveyor 1 when the limiting plate 10 pushes the stacked food.
[0026] Example 2
[0027] Please see Figure 1 , Figure 2 and Figure 5 The present invention provides a technical solution: a fixing block 17 is fixedly connected to both sides of the microwave conveyor 1 and in front of the electric telescopic rod 12. A guide post 15 is fixedly connected to the top of the fixing block 17. A guide rod 16 is slidably connected inside the guide post 15. The top of the guide rod 16 extends above the guide post 15 and is fixedly connected to the bottom of the connector 13. A dehumidification pipe 21 is installed on the microwave box 19. The food inside the microwave box 19 is sterilized by a microwave generator installed inside the microwave box 19. Microwave suppressors are installed inside the feeding box 18 and the discharging box 20. The two electric telescopic rods 12 are moved synchronously by an external controller. When the connector 13 moves, it drives the guide rod 16 to slide inside the guide post 15.
[0028] In summary, when using this food sterilization machine for food processing, the position of the back plate 14 is adjusted according to the method of placing food on the surface of the conveyor belt inside the microwave conveyor 1, such as manual pouring or conveyor conveying. The connecting piece 13 and the back plate 14 are pushed upward by the telescopic end of the electric telescopic rod 12, so that the back plate 14 moves above the microwave conveyor 1, so that one end of the microwave conveyor 1 is connected to the other end of the conveyor, thereby allowing the food to be conveyed to the surface of the conveyor belt inside the microwave conveyor 1. Alternatively, the connecting piece 13 and the back plate 14 can be moved downward by the telescopic end of the electric telescopic rod 12, blocking the front end of the microwave conveyor 1, so that food can be poured in manually and prevent the food from falling out from the front end of the microwave conveyor 1.
[0029] Adjust the position of the limiting plate 10 according to the height of the food being placed. Then, unscrew one end of the screw 5 out of the positioning groove 4 and the insertion hole 3. Next, move the top plate 9 and the limiting plate 10, causing the top plate 9 to move the moving column 23 inside the column 2. Observe the scale on the ruler 7 pointed to by one end of the pointer block 8 to obtain the height of the limiting plate 10. Then, screw one end of the screw 5 into the insertion hole 3, and then screw the other end of the screw 5 into the positioning groove 4 to fix the positions of the moving column 23, the top plate 9, and the limiting plate 10. This ensures that when the conveyor belt on the microwave conveyor 1 moves the food, the stacked food passes under the limiting plate 10. The height between the limiting plate 10 and the conveyor belt on the microwave conveyor 1 can only accommodate one food item. The food stacked on top of the food is pushed to the surface of the conveyor belt of the microwave conveyor 1, allowing the food to enter the feeding box 18, the microwave box 19, and the discharging box 20. Then, the food moves out from the discharging box 20 and is microwave-sterilized by the microwave generator inside the microwave box 19.
