Powder pre-freezing treatment device of tray type freeze dryer

Abstract

The invention relates to the field of freeze dryers, in particular to a powder pre-freezing treatment device of a tray type freeze dryer. The technical aim is to provide the powder pre-freezing treatment device of the tray type freeze dryer. According to the technical scheme, the powder pre-freezing treatment device of the tray type freeze dryer comprises a supporting foot stool, an operation control screen, a first mounting supporting column, a second mounting supporting column and the like; the lower portion of the first mounting supporting column is welded to the supporting foot stool; the lower portion of the second mounting supporting column is welded to the supporting foot stool; and the device has the advantages that automatic taking and placing of material trays in a material shelf are achieved, powder is automatically added into the trays layer by layer, it is guaranteed that the powder is flattened and cooled evenly, the material shelf and the material trays are automatically placed into a cold trap, hands are prevented from being frostbitten by the cold trap, manual taking and placing operation is omitted, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of freeze dryers, in particular to a tray-type freeze dryer drug powder prefreezing treatment device. Background technique [0002] Cold dryer is the abbreviation of refrigerated dryer. The cold dryer is a new technology and belongs to the air source processing component in the pneumatic system. [0003] At present, in the prior art, during the use of the tray-type freeze dryer, pre-freezing is required before the freeze-drying operation of the medicinal powder. During the pre-freezing operation, the material tray needs to be manually removed from the material rack, and then the medicinal powder Add it to the tray, but during the manual operation, when the powder is dumped, the powder will float, and it will be inhaled by the human body in the air, which will endanger human health. Waste, after the material tray is filled, it is necessary to manually re-place the material tray on the material rack, and then manually ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the prior art, during the use of the tray type freeze dryer, pre-freezing is required before the freeze-drying operation of the medicinal powder. During the pre-freezing operation, the material tray needs to be manually removed from the material rack, and then the medicinal powder Add it to the tray, but during the manual operation, when the powder is dumped, the powder will float, and it will be inhaled by the human body in the air, which will endanger human health. Waste, after the material tray is filled, it is necessary to manually re-place the material tray on the material rack, and then manually place the material rack into the cold trap. In the process of continuous freezing operation, the temperature in the cold trap is low, and artificially inserting hands into the cold trap for many times in a short period of time will cause frostbite to the staff. Technical problem: provide a tray type freeze dryer for pre-freezing of medicine powder processing device
