Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable drying, in particular to freeze-dried fruit and vegetable drying equipment with a sterilization structure. Background Art

[0002] Freeze-dried fruit and vegetable drying equipment is a kind of equipment specially used to remove moisture from fresh fruits and vegetables through low-temperature vacuum drying technology, so as to obtain freeze-dried fruits and vegetables that retain their original color, aroma, taste and nutrients. The working principle of freeze-dried fruit and vegetable drying equipment is mainly to use the principle of low-temperature sublimation under a vacuum environment to directly sublimate the moisture in fruits and vegetables from solid to gas, thereby achieving the purpose of removing moisture. Compared with traditional hot air drying, this drying method can better retain the nutrients and taste of fruits and vegetables.

[0003] Existing drying equipment is difficult to perform simultaneous freeze-drying operations on large quantities of fruits and vegetables at one time, resulting in limited freeze-drying efficiency. After the processing is completed, the materials need to be taken out manually, which is cumbersome and difficult to meet the needs of high-efficiency freeze-drying processing of fruits and vegetables.

[0004] The existing patent (Announcement No.: CN219868791U) discloses a freeze-dried fruit and vegetable drying device, which includes a bottom plate, and a drying processing structure is provided on the upper end of the bottom plate; the drying processing structure includes: two supporting columns, a processing box, a material taking component, a motor, a stirring shaft, a feeding port, an air inlet pipe group, an operating box, a plurality of heating plates, a fan, an air outlet pipe and a supporting cylinder; it can store large quantities of fruits and vegetables synchronously through the processing box, and the stirring shaft can make the internal fruits and vegetables evenly heated, and the side-opening door is used to cooperate with the supporting cylinder to change the angle of the processing box, and a large amount of freeze-dried can be directly discharged through the opening on one side of the processing box, thereby increasing the overall processing efficiency of freeze-drying.

[0005] In view of the above problems, although the solution provided by the existing patent can store large quantities of fruits and vegetables simultaneously through the processing box, it does not have a sealing structure. After the vacuuming is completed, external air can easily enter the interior, reducing the drying effect of the fruits and vegetables. Summary of the invention

[0029] By adopting the above technical solution, before using the freeze-dried fruit and vegetable drying device with a sterilization structure, the device housing 1 is first placed in a suitable position, the placement piece 52 is taken out through the placement plate 51 set on the fixing frame 5, and then the fruits and vegetables to be processed are placed in the placement piece 52. When putting it back, the limiting rod 54 on the mounting tube 53 is manually pulled to push the first spring 55 to be compressed, and then the placement piece 52 is put back, and the limiting rod 54 is manually released. Under the action of the elasticity of the first spring 55 itself, the limiting rod 54 can be pushed to reset, so that the end of the limiting rod 54 contacts the outer surface of the placement piece 52, thereby limiting the placement piece 52, and then the protective cover 31 is closed.

When putting them back, first manually pull the limit rod 54 on the installation tube 53 to push the first spring 55 to compress, then put the placement piece 52 back, manually loosen the limit rod 54, and under the action of the elasticity of the first spring 55 itself, the limit rod 54 can be pushed to reset, so that the end of the limit rod 54 contacts the outer surface of the placement piece 52, thereby limiting the placement piece 52, and then close the protective cover 31. With the cooperation of the sealing groove 32 and the sealing ring 3, it can play a sealing role. The set vacuum pump 71 is started to extract the air inside the placement box 2. The air passes through the inside of the one-way pipe 7 and passes through the connecting plate The through hole on 72 will push the limiting plate 73 to move, so that the limiting plate 73 drives the connecting rod 74 to move and compress the second spring 75. At this time, the internal air can be discharged to the outside. After the vacuuming is completed, the second spring 75 will push the limiting plate 73 to reset, thereby reducing the entry of external air. The ozone generator 4 arranged in the placement box 2 can play a certain sterilization role. After the fruit and vegetable processing is completed, the solenoid valve 9 on the exhaust pipe 8 is started, so that the external air enters the placement box 2, so that the protective cover 31 can be opened, which is convenient for taking out the fruits and vegetables.
