Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a device for preserving fruits and vegetables and removing pesticide residues. Background Technology

[0002] In recent years, with the continuous improvement of agricultural technology, fresh fruits and vegetables are available year-round. Before reaching the table, fruits and vegetables undergo various stages including centralized storage, transportation, wholesale, and sales. During these stages, the preservation requirements for fruits and vegetables are very high. Improper handling can easily lead to rotting and dehydration, resulting in incalculable losses. Furthermore, once fruits and vegetables reach the table, their surfaces may contain pesticide residues. Improper cleaning can compromise food safety and affect public health. Therefore, the rotting, dehydration, and pesticide residues of fruits and vegetables remain persistent problems for the public.

[0003] Firstly, the main cause of spoilage and deterioration of fruits and vegetables is the growth of microorganisms. For example, fungi such as Penicillium and Aspergillus secrete pectinase on the surface of fruits and vegetables to destroy plant cell walls, leading to softening and rotting of the fruit, thus causing spoilage and deterioration.

[0004] Secondly, the main reason for the water loss in fruits and vegetables is that they release moisture into the environment during transportation, leading to dehydration. For example, the high temperature environment during transportation accelerates the cellular respiration of fruits and vegetables, causing a large amount of water to evaporate through stomata and the epidermis, resulting in water loss.

[0005] Finally, to protect fruits and vegetables from pests, pesticides need to be sprayed on them during the planting process. Although the government and society are now advocating green farming and minimizing the use of highly toxic and persistent pesticides, they cannot be completely eliminated in the near future. Large amounts of pesticides are still used, making pesticide residues in various agricultural products a persistently prominent issue.

[0006] Therefore, there is an urgent need for a device that can reduce the spoilage and dehydration of fruits and vegetables, and remove pesticide residues, thereby improving the preservation of fruits and vegetables while ensuring people's health and safety. Utility Model Content

[0098] In one embodiment of this utility model, because the ozone pipeline 303 is far from the end of the ozone generator 301 (i.e. Figure 2 The left end of the ozone pipeline 303 is higher than the bottom inner wall of the water storage shell 102, and preferably the same height as the top end of the water storage shell 102. Therefore, when the water storage shell 102 collects hypochlorous acid aqueous solution, the hypochlorous acid aqueous solution in the water storage shell 102 will not flow into the ozone pipeline 303 and cause blockage of the ozone pipeline 303, thereby ensuring the normal operation of the work.

[0099] According to one embodiment of the present invention, the bottom end of the water storage shell 102 is an inclined structure (not shown in the figure), and the inclination angle of the inclined structure of the water storage shell 102 is 10°-20°, preferably 10°. The lowest end of the inclined structure of the water storage shell 102 (i.e. Figure 2 The right end of the water storage shell 102 and the end of the drain pipe 106 near the water storage shell 102 (i.e., Figure 4 The drain pipe 106 is positioned at the left end of the middle drain pipe 106, meaning that the drain pipe 106 is located at the lowest end of the inclined structure of the water storage shell 102.

[0100] In one embodiment of this utility model, by setting an inclined structure, the efficiency of hypochlorous acid aqueous solution in the water storage shell 102 entering the drain pipe 106 can be improved, thereby improving the discharge efficiency of hypochlorous acid aqueous solution in the water storage shell 102.

[0101] The working process of this device will be briefly described below with reference to the above embodiments:

[0102] First, the operator turns on all electrical equipment in the unit and connects a pipe specifically for collecting acid to the drain pipe 106.

[0103] Then, fruits and vegetables requiring preservation and pesticide residue removal are placed on conveyor belt 104. Conveyor belt 104 then transports the fruits and vegetables. During transport, the fruits and vegetables are sprayed by spray nozzles 207, which sprays a hypochlorous acid solution onto their surface for microbial disinfection, moisture retention, and pesticide residue removal. Simultaneously, during transport, ozone in ozone pipe 303 coats the surface of the fruits and vegetables, further disinfecting and removing pesticide residues.

[0104] Finally, the fruits and vegetables sprayed with hypochlorous acid solution and coated with ozone will be transported by conveyor belt 104 to subsequent stages, so as to facilitate subsequent centralized storage, transportation, wholesale and sales.

[0105] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0106] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
