Solid-liquid separation method for replacing conventional alcohol deposition standing separation of Chinese medicaments

The invention discloses a solid-liquid separation method for replacing conventional alcohol deposition standing separation of Chinese medicaments, namely a diaphragm plate pressure filtration method. The method mainly comprises the steps of alcohol depositing, filter pressing, squeezing, discharging filter residues, combining filter pressing liquid and squeezing liquid, and the like. According to the method, the alcohol deposition for extracting a concentrated clear cream of Chinese medicament solution can be quickly and efficiently performed, the processing time is greatly shortened, the recovery rate of an alcohol-containing liquid medicine can be improved, and the liquid content and the discharge amount of the filter residues can be reduced.
