Device for extracting drug extract

Abstract

The invention relates to a device for extracting drug extract. The device comprises a decoction device, a cooler, a centrifugation separator, a filter, a filtrate transfer device and a vacuum drier. The bottom of the decoction device is provided with a drainage outlet. The drainage outlet is connected to the cooler. The cooler comprises a liquid storage tank. A conical diverter is arranged at the upper part in the liquid storage tank. The side wall of the liquid storage tank is provided with an inward inclined surface. The inward inclined surface is provided with a heat dissipation air hole. The drainage outlet of the cooler is connected to the centrifugation separator through a lifting conveyer pipe. The centrifugation separator is connected to the filter. The filter is connected to the filtrate transfer device. The filtrate transfer device is connected to the vacuum drier. The filter is connected to a filtration washing liquid tank. At least two filtering membrane modules are arranged in the filter. The device realizes drug one-stop processing and finally produces standby powder.

Description

technical field [0001] The invention belongs to the technical field of extraction of medicinal material extracts, and in particular relates to a device for extracting medicinal material extracts. Background technique [0002] At present, the method of extracting organic components from medicinal materials usually adopts warm soaking method, boiling method, dilute alcohol extraction and acid alcohol extraction, etc., and the purification methods mostly use alcohol precipitation method, water alcohol method, stone mercaptan method, extraction method, large Pore ​​resin adsorption method, etc.; Among them, alcohol precipitation method and water precipitation method can only achieve the purpose of preliminary purification, and the amount of cream is large, and the content of organic acid is low. Lime-sulfur method, extraction method and macroporous resin adsorption method are used alone, and there are still some shortcomings for some preparations with high requirements. Large, ...

AI Technical Summary

Problems solved by technology

Lime-sulfur method, extraction method and macroporous resin adsorption method are used alone, and there are still some shortcomings for some preparations with high requirements. large, making the color of the preparation darker, the macroporous resin adsorption method needs to be processed repeatedly, the operation is cumbersome, the reproducibility is poor, and there are organic residue problems, which directly affect the safety and stability of the preparation

There are many patents in China that introduce the preparation equipment or system of medicinal material extracts, but they all have problems such as high ointment yield, low content, low transfer rate, and complicated operation.
