Extracting machine for traditional Chinese medicines

Abstract

The traditional Chinese medicine extracting machine includes a soaking extracting barrel drive by one motor to rotate and with one inner container; and one rotating pipe driven by another motor and with one stirrer. The rotating pipe has liquid discharging small holes in the section inside the inner cavity of the soaking extracting barrle. One mixing pipe is connected to the upper end of the rotating pipe, and one solvent pipe and one steam pipe are connected to the other end of the rotating pipe. There is diversion trench in the inner side and inner bottom of the soaking extracting barrle. The traditional Chinese medicine extracting machine has short extracting period, less solvent consumption and simple structure.

Description

technical field [0001] The invention relates to a device for extracting traditional Chinese medicine. Background technique [0002] The common methods for extracting active ingredients from Chinese herbal medicines include maceration, decoction and percolation. Among them, the equipment used in the maceration method includes tanks, altars or macerators equipped with stirring mechanisms, and the equipment used in the decoction method includes casserole. , sandwich pot, decocting machine or multi-functional traditional Chinese medicine extraction tank, and the equipment used in the diafiltration method includes a diafiltration barrel, a pressurized diafiltration device, a double-effect countercurrent diafiltration device or a continuous diafiltration device. The above-mentioned devices, among them The common disadvantages are that the dregs contain a lot of liquid, the extraction time is long, and the amount of solvent required is large. With the development of ...

Problems solved by technology

With the development of traditional Chinese medicine pharmaceutical technology, many inventors have studied and improved the extraction equipment of traditional Chinese medicine, and proposed some new technical solutions, such as the "low temperature dynamic infiltration four-stage fast solid-liquid separation extraction unit" with application number 99113177 ", realized the continuous completion of the cleaning and disinfection and crushing of medicinal materials, dynamic rapid leaching, four-stage solid-liquid separation, clarification separation and automatic merging of the separated liquid in the same unit. The degree of automation is high, but the equipment is complicated, the cost is high, and the amount of solvent required Still very big; Patent No. 98248372 "a kind of eucommia gum extractor" includes a cylinder, which is equipped with a shaft sleeve tube with a stirring paddle and a spray hole and a composite filter screen cylinder, and the bottom of the cylinder is a belt The slag discharge device of the side sieve plate, although the structure of this extractor is simple, it still needs a large amount of solvent, and the extraction time is long
