Device and method for extracting and concentrating traditional Chinese medicine

Abstract

The invention relates to the technical field of extracting and concentrating of the traditional Chinese medicine, and in particular relates to a method and a device for extracting and concentrating the traditional Chinese medicine. The method for extracting and concentrating structurally comprises an extracting unit and a concentrating unit, wherein the extracting unit comprises an extracting tank and a liquid medicine storage tank, wherein a piston capable of moving up and down is arranged in the extracting tank; when the piston moves upwards under the action of the driving force, dredges of decoction in a pressurizing chamber are pressurized and further squeezed; the concentrating unit comprises a concentrating container, a vacuum pump and a heating device for heating up the concentrating container, wherein a step-shaped evaporation plate assembly of a liquid medicine thin film is formed in the concentrating container, so that the liquid medicine can be circulated and concentrated. Compared with the prior art, the extracting and concentrating efficiency is high, the heating time is short, and the damages to the active ingredients of the medicine are reduced.

Description

technical field [0001] The invention relates to the technical field of extracting and concentrating traditional Chinese medicines, in particular to a device for extracting and concentrating traditional Chinese medicines and a method for extracting and concentrating traditional Chinese medicines using the device. Background technique [0002] There are many kinds of Chinese herbal medicines, which have a wide range of pharmacological effects, and their curative effects are increasingly valued in the world today, so they have broad development potential, and more and more people are devoted to the research and development of Chinese herbal medicines. To realize the medicinal value of traditional Chinese medicine, the extraction and concentration process of traditional Chinese medicine and its equipment are crucial to the research and development of traditional Chinese medicine, which directly affects the extraction rate of active ingredients of medicine, the utilization rate of...

Problems solved by technology

[0003] In the prior art, the extraction and concentration process of Chinese medicinal materials is divided into two stages of extraction and concentration. During the extraction process, Chinese medicinal materials and solvents are put into the extraction container, and then heated and reacted under normal pressure for a period of time to make the extraction container The medicinal material is dissolved in the solvent; after the extraction is completed, the medicinal liquid in the extraction container is transferred to a concentration device (such as a rotary evaporator), and the water and solvent in the medicinal liquid are further evaporated by heating to achieve the purpose of concentration; the above process and The disadvantages of the equipment are: 1) The heating time of the two stages of extraction and concentration is long, resulting in high energy consumption; 2) Long-term heating will destroy the active ingredients of the drug, and the heating in the process of extraction and concentration is at normal pressure and 100°C It is carried out under high temperature conditions, and high temperature will have a great impact on heat-sensitive traditional Chinese medicine; 3) The existing extractor has a lot of residual medicinal liquid, the extraction and transfer rate of active ingredients is low, and the concentration device evaporates low efficiency
