Square vacuum drier

Abstract

An efficient square vacuum drier comprises a box door (27) with the heat insulation function and a drier body (20); a heating plate layer (4) is placed in a box, a heat source pipeline of the plate layer and box rubber (9) of the box are sealed in a filling manner, an inlet and an outlet of a heat source adopt an adjusting valve (6) for flow single control, the heating plate layer is placed on a shelf (10) on the welding box, a heating plate layer (2) is arranged at the bottom of the top, each layer of the plate layer (2) is provided with an online cleaning system (3), a cleaning tank car (24) is arranged, cleaning and pollution discharging are achieved through injection and discharging of pneumatic diaphragm pumps (23 and 25), and a pollution discharge opening (19) is formed in the bottom of the door.

Description

Technical field: [0001] The invention relates to a square vacuum drier, which is a high-efficiency drier for pharmaceuticals in the pharmaceutical industry. Background technique: [0002] At present, the square vacuum dryers for drying medicines in the domestic market cannot control the temperature of each plate layer very uniformly while drying medicines. The moisture content of dried products in each layer of drying trays is not uniform, and drying takes too long. Long, there is no heating layer on the top and bottom of the box, the evaporated solvent is adsorbed on the top and bottom to become dew drops, and the dew drops cannot be converted into gas. Although there is an arc top, it will eventually fall into the product, and the bottom The storage solution cannot be removed in time. The connection of the heat source pipeline is mostly in the cavity, and there is a dead angle between the connecting screw and the flange. Without a professional online cleaning system, it ...

AI Technical Summary

Problems solved by technology

Without a professional online cleaning system, it is impossible to ensure that the cavity is thoroughly cleaned. According to the GMP equipment use specification, the equipment must be thoroughly cleaned in the cavity after use, and the board layer, top and bottom must be dried, and water stains must be removed in time. Drying to avoid the growth of bacteria. As mentioned above, this type of equipment can no longer guarantee the production of qualified products, and it will pose a risk to the purity of the drug during the production process.
