Description

TECHNICAL FIELD

[0001] The utility model relates to medicine extraction equipment technical field, concretely relates to a Chinese herbal medicine continuous extraction device. BACKGROUND

[0002] The process of extracting effective components from Chinese herbal medicine is an important environment for modernization research of traditional Chinese medicine, and the principle of traditional Chinese medicine extraction mainly includes two methods of physical extraction and chemical extraction. Physical extraction refers to extracting effective components from Chinese herbal medicine by physical methods, including immersion, distillation, cold immersion, hot immersion and the like. Among them, immersion is the most common physical extraction method, and its principle is to immerse Chinese herbal medicine in a solvent for a period of time, so that the effective components are dissolved in the solvent, and then the extract is obtained by evaporating the solvent.

[0003] To improve the medicine extraction rate, the immersion temperature can be increased, the immersion time can be prolonged, and the solvent amount can be increased. However, in the extraction process of some Chinese herbal medicines (such as ginseng medicines), the temperature has requirements, and the increase of temperature may accelerate the kinetics of drug molecules, so that the medicine is extracted efficiently, but too high temperature will damage the structure of drug molecules, resulting in loss of traditional Chinese medicine components and decrease of product quality. The method of directly heating the solvent temperature in the immersion tank is relatively simple, but as the immersion time increases, the concentration of the solvent in the medicine solution decreases, and the immersion speed slows down. Simply increasing the amount of solvent to increase the concentration of solvent in the medicine solution increases the consumption of solvent, thereby increasing the extraction cost. Therefore, in order to improve the medicine extraction rate, the immersion temperature, the immersion time, the solvent consumption and the like need to be considered comprehensively. SUMMARY
