Freeze dryer and supporting plate feeding and discharging system thereof

Abstract

The invention discloses a freeze dryer and a supporting plate feeding and discharging system thereof. The supporting plate feeding and discharging system of the freeze dryer involves supporting plates, a base and a lifting mechanism used for controlling the supporting plates to ascend and descend, wherein the base is provided with idler wheels capable of travelling on a feeding and discharging machine base, and the lifting mechanism is arranged on the base; when the supporting plates are placed on the lifting mechanism, if the lifting mechanism is in a first working state, the bottoms of the supporting plates are located at first horizontal height, and the first horizontal height is the horizontal height where the machine base upper surface of the feeding and discharging machine base is located; and if the lifting mechanism is in a second working state, the bottoms of the supporting plates are located at second horizontal height, and the second horizontal height is higher than the first horizontal height. The freeze dryer and the supporting plate feeding and discharging system thereof can solve the friction problem in the supporting plate feeding and discharging process of the freeze dryer, avoids the risk caused by friction, is beneficial to reduce the labor intensity of an operator, and can normally feed products with low-temperature feeding requirement.

Description

technical field [0001] The invention relates to the technical field of freeze-drying, in particular to a tray feeding and discharging system for a freeze-dryer and a freeze-dryer equipped with the system. Background technique [0002] Vacuum freeze drying is also called sublimation drying. The principle is to freeze the material so that the water contained in it turns into ice cubes, and then sublimate the ice under vacuum to achieve the purpose of drying. [0003] Vacuum Freeze Dryer (referred to as Freeze Dryer): A device that dries the moisture in medicines, food, health care products, cosmetics and other products that need to be dried and stored under low-temperature vacuum. [0004] Raw material drug freeze-drying machine: a freeze-drying machine specially designed for freeze-drying raw material drugs. A relatively shallow box with a lid. [0005] The working process of the freeze dryer includes such as the feeding process and the discharging process: the feeding pro...

AI Technical Summary

Problems solved by technology

[0006] During the above-mentioned feeding and discharging process, due to the friction between the pallet and the board layer, friction debris is generated, which leads to pollution problems

[0007] In addition, for some products that require low-temperature feeding, when the freeze dryer feeds, the slab needs to be frozen to a suitable temperature, which will be much lower than the freeze-drying front chamber, so frost will form on the surface of the slab. The traditional method pushes the tray directly on the board without considering the friction problem, and even the movement of the pallet on the board is already a problem, and excessive force will cause the liquid medicine to spill, resulting in product waste and loss
