beer stainless steel tank is suitable for extracting/concentrating the active ingredients of Chinese herbs and various plants, realizing the recovery of solvents and aromatic oils. Now let me talk about the extraction method of beer stainless steel tank.

1. Impregnation method: The method of quantitative impregnation of medicinal materials for a certain time and extraction of medicinal materials. The solvent. It is suitable for viscous drugs, unorganized drugs, fresh and easy to swell drugs.

2. Percolation method: put the drug coarse powder into the percolation tank, and continuously add solvent from the top. The invention relates to a method for leaching drugs by continuously discharging leachate from the lower part of a percolate tank.

3. Reflux method: Extract medicinal materials with volatile organic solvents such as ethanol, concentrate volatile components, and then return to the extractor repeatedly to extract medicinal materials.

4. Pre-incorporation of supercritical fluid: This method is to dissolve the soluble components in the supercritical fluid through the extractor at a specific temperature for the fluid in a critical state, such as CO2.

5. Steam distillation: This is an application of insoluble, non-chemically reactive liquids, following Dalton's law, that is, the total vapor pressure of the mixture is equal to the sum of the saturated vapor pressures of the components. Temperature and method are extracted by distillation of the active ingredient.

6, frying method: water as a solvent, boiling for a certain time, extract the ingredients. It is suitable for medicinal materials with active ingredients soluble in water and stable to heat.
