[0041] According to another aspect of the present invention, a process for extracting, deodorizing, sterilizing and removing pesticide residues from onion juice is provided, comprising the following steps:

[0042] S1. Removing pesticides and odors from the surface of onions: Put the chopped onions into the filter cartridge 1107 on the left and lift the filter cartridge 1107, then rotate the rotating plate 8 180 degrees, and then lower the filter cartridge 1107 into the ultrasonic cleaning box 2. At the same time, clean water is introduced into the ultrasonic cleaning box 2. During the ultrasonic cleaning of the onions, the stirring rod 1123 rotates to facilitate the cleaning force. After the cleaning is completed, the cleaning water is discharged;

[0043] S2, onion sterilization: edible sterilizing liquid is introduced into the liquid spray channel 4, and the stirring rod 1123 is rotated at the same time to sterilize the onions comprehensively. After the sterilization is completed, clean water is introduced into the liquid spray channel 4 to flush away the sterilizing liquid;

[0044] S3, onion water removal: move the filter cartridge 1107 upward, then quickly rotate the filter cartridge 1107 to remove the washing water remaining on the surface of the onion, completely raise the filter cartridge 1107 and then rotate the rotating plate 8 180 degrees, lower the filter cartridge 1107, flip the support plate 1101 180 degrees, so as to automatically unload the onion, and then flip the support plate 1101 180 degrees again to continue loading;

[0045] S4. In the subsequent processing of onions, one or more of the following methods, including gamma rays, microwaves, ultraviolet rays and ozone, are used to sterilize the onions.

[0046] The working principle of the device is as follows: first, clean water is passed into the ultrasonic cleaning box 2, two filter cartridges 1107 are lowered, and unwashed onions are passed into the filter cartridge 1107 on the left. After the feeding is completed, the two filter cartridges 1107 are raised again, and then the rotating plate 8 is rotated 180 degrees, and then the two filter cartridges 1107 are lowered, and the filter cartridge 1107 containing onions is inserted into the filter cartridge 1107 and immersed in water to clean the onions. The support box 1108 is finally placed on the pad 12. When the filter cartridge 1107 continues to be moved down, the latch 1119 is squeezed by the squeezing block 1118 and moves, and the latch 1119 is inserted into the corresponding card slot 1104 to lock the rotating seat 1105, and the block 1122 is finally stuck in the card sleeve 11 12, the rotation of the ferrule 1112 drives the block 1122 and the stirring rod 1123 to rotate, thereby automatically stirring the onions, making the cleaning effect more comprehensive and efficient. After completing the cleaning operation, first open the electric drain valve 3 to drain the dirty water, and then close the electric drain valve 3 after the drainage is completed, lift the filter cartridge 1107 and make the support box 1108 leave the pad 12, the block 1122 is separated from the ferrule 1112, and then the edible sterilizing liquid is introduced into the spray channel 4, and the spray channel 4 sprays the edible sterilizing liquid on the onions to perform the sterilization operation. At the same time, the rotation of the ferrule 1112 drives the rotating seat 1105 and the filter cartridge 1107 to rotate, thereby fully sterilizing, and then pass clean water into the spray channel 4 to flush Wash off the sterilizing liquid on the surface of the onions, raise the filter cartridge 1107 again and make it leave the liquid, then quickly rotate the filter cartridge 1107 to automatically discard the water, then raise the filter cartridge 1107 and reset it, rotate the rotating plate 8 180 degrees again and lower the filter cartridge 1107, flip the filter cartridge 1107 to pour out the onions, and after the unloading operation is completed, the filter cartridge 1107 can be flipped back, and then the above operation is repeated, so that the onions can be cleaned and sterilized in an orderly manner. While the previous cylinder of onions is being cleaned and sterilized, the next cylinder of onions can be passed into another filter cartridge 1107, and gamma ray sterilization, microwave sterilization, ultraviolet sterilization and ozone sterilization can be used in the subsequent processing of onions. One or more of the above are used to sterilize onions. Gamma ray sterilization destroys the DNA, proteins and enzymes of microorganisms, causing the death of microorganisms, thereby achieving the sterilization effect. Microwave sterilization uses the heat energy generated by microwave irradiation to kill microorganisms and spores, which is suitable for the sterilization of liquid and solid materials. The principle of ultraviolet sterilization is to destroy and change the DNA structure of microorganisms through ultraviolet irradiation, causing the bacteria to die immediately or be unable to reproduce offspring, thereby achieving the purpose of sterilization. Ozone decomposes the enzymes required for glucose in bacteria through oxidation, causing the bacteria to be inactivated and killed, thereby achieving the purpose of sterilization. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0047] In summary, the onion juice extraction, deodorization, sterilization and pesticide residue removal equipment and process achieve the purposes of comprehensive and efficient cleaning and deodorization, self-locking switching, comprehensive and uniform sterilization, automatic dehydration, automatic unloading and continuous and efficient processing, meeting people's usage needs.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
