Medicine vacuum dryer

Abstract

The invention relates to the field of general pharmaceutical equipment, in particular to a medicine vacuum dryer. The medicine vacuum dryer comprises a dryer body, a conveying belt and a programmable logic controller (PLC). The PLC is connected with the dryer body. A feeding hopper is arranged at the left end of the dryer body. A feeding power pump is arranged between the feeding hopper and the dryer body. The feeding power pump is connected with a mechanical distributor. The conveying belt is arranged inside the dryer body. A heating block is arranged below the conveying belt. The heating block is connected with a heating control system. A cooling block is arranged at the right end of the heating block. The cooling block is connected with a cooling control system. According to the medicine vacuum dryer, microcomputers and the mechanical-electrical integration technique are adopted, the number of pollution links is reduced, the production efficiency, the economic benefits and the social benefits are improved, the medicine vacuum dryer is quite ideally linked, intelligent and automatic drying equipment for conducting vacuum low-temperature heating and drying on various extracts by large-sized, middle-sized and small sized Chinese medicine factories and hospital preparation rooms, and the whole equipment is compact in structure, simple in theory and worthy of popularization.

Description

technical field [0001] The invention relates to the field of general pharmaceutical equipment, in particular to a medicine vacuum dryer. Background technique [0002] Vacuum belt drying technology equipment has a wide range of applications, and is applicable to the drying of various traditional Chinese medicine extracts (referred to as "extracts"), especially for extracts with high viscosity, easy agglomeration, thermoplasticity, and heat sensitivity. At present, there is still a certain gap between my country's vacuum belt drying technology and equipment compared with similar products in developed countries in the world. Although the technology and equipment imported from abroad have obvious advantages, they are expensive and have high maintenance costs. Therefore, only a few in China The application of large-scale Chinese medicine factories has greatly limited the wide application of foreign vacuum belt drying technology equipment in domestic small and medium-sized Chinese m...

[0002] Vacuum belt drying technology equipment has a wide range of applications, and is applicable to the drying of various traditional Chinese medicine extracts (referred to as "extracts"), especially for extracts with high viscosity, easy agglomeration, thermoplasticity, and heat sensitivity. At present, there is still a certain gap between my country's vacuum belt drying technology and equipment compared with similar products in developed countries in the world. Although the technology and equipment imported from abroad have obvious advantages, they are expensive and have high maintenance costs. Therefore, only a few in China The application of large-scale Chinese medicine factories has greatly limited the wide application of foreign vacuum belt drying technology equipment in domestic small and medium-sized Chinese medicine factories and hospital preparation rooms. The automation level and production capacity of domestic vacuum belt drying technology equipment are relatively low. , and cannot meet the requirements and needs of various types of traditional Chinese medicine factories and hospital preparation rooms for fully automatic vacuum drying of extracts, so it is necessary to design a drug vacuum dryer
