Embodiment Construction

[0013] Example structure see figure 1 , figure 2 .

[0014] The device for continuous countercurrent extraction of traditional Chinese medicine includes a box 15 and a base 17. The base 17 is mainly composed of a fixed bracket 1 and a lifting bracket 10, and the box 15 is mounted on the base. The horizontal inclination angle of the box 15 can be adjusted within 0-10° through the lifting bracket 10. A pair of counter-rotating screws 13 and 14 are installed in parallel in the box 15. Screws 16 are fixed on the screws 13 and 14, and the pitches of the screw 16 are not equal. The spiral piece 16 is provided with return holes, and each spiral piece 16 of the embodiment is provided with three return holes. The two ends of the screws 13 and 14 are respectively installed on the two end faces of the box 15, one end of which is connected to the motor 4 equipped with a governor 3 through a coupling 5. The rotation speed of the screws 13 and 14 can be adjusted by the governor 3. . The coupli...

Abstract

A continuous counter-current extractor for Chinese medicine is composed of a base and a case body in which there are a pair of parallel screen rods driven by motor to rotate in different directions. Said screw rod has the spiral fin with reflux holes on it. It features the integration of stirring, mixing, delivery and pressure filtering.

Description

Technical field [0001] The invention relates to a countercurrent extraction device, in particular a continuous countercurrent extraction device for traditional Chinese medicine, which is used for the extraction and separation of traditional Chinese medicine, and can adopt different extraction processes according to different extracts to realize continuous and efficient countercurrent extraction. Background technique [0002] The extraction and separation technology and equipment of traditional Chinese medicine are essential to improve the utilization rate and therapeutic effect of traditional Chinese medicine. Traditional Chinese medicine extraction mainly uses decoction, water distillation, solvent extraction and so on. This extraction method is easy to operate and does not require very high technology and equipment, so it is widely used. But it also has some disadvantages, such as long extraction time, more impurities in the extract, and low extraction rate of effective ingredi...
