Description

Technical Field

[0001] The utility model belongs to the field of traditional Chinese medicine extracts, in particular to a concentration device. Background Art

[0002] Chinese herbal medicine has a history of thousands of years in treating diseases. However, traditional Chinese herbal medicine is often slow to take effect and has low efficacy. This is because traditional Chinese medicine has a very low utilization rate in animals. Chinese herbal medicine extracts fundamentally overcome the shortcomings of traditional Chinese medicine, allowing Chinese medicine to be quickly absorbed by animals, with high bioavailability and fast efficacy, comparable to Western medicine. However, there are still some problems to be solved in the preparation of Chinese herbal medicine extracts, such as how to determine the maximum concentration ratio when concentrating Chinese herbal medicine extracts and how to achieve the best level of efficacy of Chinese medicine. There are three methods for concentrating Chinese herbal medicine extracts: atmospheric pressure concentration, vacuum concentration, thin film concentration, and multi-effect concentration. Among them, vacuum concentration, thin film concentration, and multi-effect concentration are suitable for the concentration of Chinese herbal medicine extracts in large factories, and the equipment investment is large. Atmospheric pressure concentration has a small equipment investment and the conditions required for concentration are easy to achieve. Therefore, it is more commonly used in some laboratories, hospitals, and homes.
