1、 Overview of alcohol precipitation tank:

Alcohol precipitation is a commonly used process step in the extraction of traditional Chinese medicine. After concentration, the extract of traditional Chinese medicine is added to ethanol for alcohol precipitation at room temperature or low temperature. Ethanol serves as a solvent to dissolve the active ingredients in the concentrated solution and as a precipitant to precipitate certain impurities. The alcohol precipitation tank uses ethanol as a solvent to separate and precipitate two or more components. The alcohol precipitation process is accompanied by a temperature control system.

2、 Structure and characteristics of alcohol precipitation tank:
The alcohol precipitation tank mainly consists of a tank body, upper and lower heads, a stirring transmission device, a sandwich and supporting heat exchange system, an adjustable supernatant discharge port, and a lower slag discharge port. The cylindrical part of the alcohol precipitation tank is generally designed with an upper elliptical head and a lower conical head structure, with a cone angle of 60 ° to 90 °. After alcohol precipitation, impurities settle at the bottom of the cone, and the clear liquid is sucked out from the upper part.

The transmission system of the alcohol precipitation tank generally consists of an explosion-proof motor, a reducer, a seal, a frame part, a stirring device, etc. When the container load is large, low-speed stirring can be selected, and conversely, a higher stirring speed can be selected. The function of the transmission system is to mix the solvent evenly in the alcohol precipitation material, which is conducive to the selective separation between the solvent and solute, and achieves the optimal separation effect.

Different mixing devices are prepared according to the size of the tank and the composition of the traditional Chinese medicine extract, and the matching specifications for mixing can be designed and manufactured according to the actual situation.
