Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of freeze drying, in particular to a feeding device for a vacuum freeze drying tank. Background Art
[0002] Vacuum freeze-drying technology is a new drying method that freezes water-containing materials into solids and uses the sublimation properties of water under low temperature and low pressure conditions to dehydrate the materials at low temperature to achieve drying. Since vacuum freeze-drying technology is carried out in a low temperature and low oxygen environment, most biological reactions are stagnant, and there is no liquid water in the treatment process. The water sublimates directly in a solid state, so that the original structure and shape of the material are protected to the greatest extent, and finally a high-quality dry product with both appearance and internal quality is obtained.
[0003] In the prior art, a utility model patent with publication number CN218915594U provides a split vacuum freeze drying tank. Aiming at the problem that the existing freeze dryer is inconvenient to load materials, resulting in poor operating effect, and the freeze dryer has high cost, high control requirements, and is not suitable for small-batch production of multiple varieties, the following scheme is proposed, which includes a supporting foot, the top of the supporting foot is fixedly connected to a tank body, and a switch door is rotatably installed on the tank body, the switch door is provided with a perspective window, and a sealing ring is fixedly installed at the connection between the switch door and the tank body.
[0004] The split vacuum freeze drying tank can only take out one set of placement plates at a time, which is inconvenient for loading and unloading materials and requires multiple unloading, which increases the workload. The support plate and the placement plate are in sliding friction contact, which makes it inconvenient to move the placement plate. Therefore, we propose a unloading device for a vacuum freeze drying tank to solve the above problems. Utility Model Content
