Continuous high-efficient vacuum concentration of Chinese medicine soup and apparatus thereof

Abstract

An apparatus for effective and continuous vacuum concentrating of Chinese-medicinal liquid is composed of the heating-evaporating unit consisting of heater and vacuum evaporator, liquid supplying tank, vapor-liquid separator, condenser, vacuumizing unit and connecting pipeline. Its process includes such steps of feeding Chinese-medicinal liquid in vacuum heater, evaporating, and condensing. Its advantages are high concentration and less loss of medicinal effect.

Description

technical field [0001] The invention relates to a process for re-concentrating traditional Chinese medicine liquid after preliminary concentration treatment in a vacuum state and the technical field of vacuum concentration equipment structure used in the process. Background technique [0002] For a long time, the concentration treatment of traditional Chinese medicine extracts generally only proceeds to the subsequent drying treatment after one concentration to produce dry Chinese medicine granules or powders. Due to the low concentration rate of the medicinal liquid, it is difficult to be directly used in the production of extract products. In order to produce extract products, the liquid medicine needs to be further concentrated. At present, the commonly used secondary concentration equipment includes tilting reaction pot, vacuum concentration reaction pot, thin film concentration and evaporation equipment, double-effect and triple-effect external circulation concentratio...

AI Technical Summary

Problems solved by technology

The tilting reaction pot has a high evaporation temperature, the material is heated for a long time, and the heat-sensitive components are easy to coke. The large amount of water vapor evaporated will easily cause mold to grow in the plant and equipment, which seriously affects the sanitation of the pharmaceutical production environment; the vacuum concentration reaction pot cannot accurately control the concentration process. The concentration effect is poor due to various process parameters; and the thin-film concentration and evaporation equipment has a high evaporation temperature, and the evaporation temperature and feed volume cannot be automatically controlled, so coking often occurs; although double-effect and three-effect external circulation concentration and evaporation equipment have It has the advantages of fast evaporation speed and high density extract, but the density of each effect cannot be automatically detected, and manual operation is required for feeding and discharging materials. There is no automatic control system for temperature, pressure and vacuum. The vacuum and condensation system consumes a lot of energy and requires equipment cleaning. Inconvenient to wait
