Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable freeze dryer technology, specifically to a freeze tray transfer device for an FD fruit and vegetable freeze dryer. Background Technology

[0002] Fresh fruits and vegetables are highly nutritious, rich in essential vitamins, minerals, and dietary fiber. However, they are prone to spoilage, and storage and transportation costs are high. Therefore, with technological advancements, freeze-dried (FD) fruits and vegetables have emerged. As a type of freeze-dried food, freeze-dried fruits and vegetables have gradually become a favorite in the snack industry, increasingly popular with consumers. The basic principle of freeze-drying fruits and vegetables is to process fresh fruits and vegetables (washed, cut, etc.) at low temperatures, then freeze them, and finally, under vacuum conditions, achieve sublimation (ice directly turning into vapor) dehydration through temperature control.

[0003] Before freeze-drying, fruits and vegetables need to be pre-frozen. Generally, they are placed in freezing trays and put into freezing equipment. Then, the freezing trays and the frozen fruits and vegetables are put into freeze dryer for freeze-drying. Since a large number of fruits and vegetables are freeze-dried at one time, multiple freezing trays need to be transferred from freezing equipment to freeze dryer repeatedly. The transfer operation is very inconvenient and takes a long time. Moreover, the freeze-drying tank door of the freeze dryer needs to be kept open for a long time, which makes the frozen fruits and vegetables prone to thawing. This may lead to damage to the fruits and vegetables initially placed in the freeze-drying tank, which is not conducive to maintaining the shape and integrity of the freeze-dried fruits and vegetables.

[0004] Therefore, we propose a frozen tray transfer device for FD fruit and vegetable freeze dryers to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a frozen tray transfer device for an FD fruit and vegetable freeze dryer, which has the following beneficial effects:

[0017] This invention, by designing corresponding limiting blocks on the surfaces of multiple freezing frames and connecting limiting holes on the surfaces of the limiting blocks, and then using the cooperation of limiting rods, pull plates, fixing grooves, positioning grooves and positioning rods to limit the movement of multiple freezing frames inside the transfer rack, facilitates the transfer of the fruits and vegetables placed in the multiple freezing frames and the transfer rack as a whole to the interior of the freeze dryer for dehydration and drying. This avoids the tedious and inefficient problem of repeatedly transferring multiple freezing frames one by one. At the same time, the overall transfer between the transfer rack and the multiple freezing frames also prevents the fruits and vegetables from melting, which is beneficial to maintaining the shape and integrity of the freeze-dried fruits and vegetables.
