Problems solved by technology

[0003] MVR (Mechanical Vapor Recompression Technology) evaporator concentration is one of the most effective methods at present, but at present all MVR evaporators are only for water extraction of traditional Chinese medicine leachate, not for alcohol extraction of traditional Chinese medicine leachate, because the evaporation of water is relatively stable, It is relatively easy to do, but the flammability and explosion of alcohol is rarely involved, especially the explosion-proof problem of the entire space is difficult to solve

Abstract

The invention discloses a double-effect MVR (mechanical vapor recompression) evaporator and an evaporation technology thereof. The double-effect MVR evaporator comprises an alcohol extract evaporation system, a water extract evaporation system and a vapor compressor, wherein the alcohol extract evaporation system is sequentially connected with the water extract evaporation system and the vapor compressor through pipelines and comprises a first-effect evaporator and a first-effect gas-liquid separator which are connected sequentially through a pipeline; the water extract evaporation system comprises a second-effect evaporator and a second-effect gas-liquid separator which are sequentially connected through a pipeline; the output end of the vapor compressor is connected with the shell pass of the first-effect evaporator of the alcohol extract evaporation system through a pipeline. The evaporator and the evaporation technology can guarantee the safety and the stability of the system on the whole and have the advantage of capability of realizing modularization and automatic production.

Description

technical field [0001] The invention relates to a double-effect MVR evaporator and an evaporation process thereof, belonging to the field of traditional Chinese medicine extraction. Background technique [0002] Evaporation and concentration of traditional Chinese medicine extract is a key energy-consuming and time-consuming process. At present, most of the evaporation methods used in China are: reaction kettle, single-effect evaporator, multi-effect evaporator, jet pump, MVR evaporator, etc., each of which has its own characteristics. Both can evaporate and concentrate the extract of traditional Chinese medicine. [0003] MVR (Mechanical Vapor Recompression Technology) evaporator concentration is one of the most effective methods at present, but at present all MVR evaporators are only for water extraction of traditional Chinese medicine leachate, not for alcohol extraction of traditional Chinese medicine leachate, because the evaporation of water is relatively stable, It i...
