This machine is a combined application device for the extraction and concentration of active ingredients in drugs. Its advantage is that it integrates extraction and concentration, and adopts a fully enclosed continuous cycle extraction and concentration. During the hot extraction process, the liquid in the extraction tank is connected to the heater and evaporator through the filter layer for cyclic concentration. The secondary steam generated by extraction and concentration flows back to the deep layer of the material in the extraction tank after being condensed by a special refrigeration condenser, allowing the material to fully contact and play a role in dynamic extraction and solvent supplementation, while shortening the extraction and concentration time, greatly improving production efficiency and drug yield.

The traditional Chinese medicine hot reflux extraction and concentration unit integrates four extraction principles: reflux, percolation extraction, countercurrent extraction, and hot reflux extraction and concentration. The two processes of traditional Chinese medicine extraction and concentration are carried out simultaneously, completing the new process of traditional Chinese medicine extraction and concentration in one go. The high-temperature decoction process with pressure under normal pressure in the extraction tank is improved, and the low-temperature extraction and concentration are carried out using vacuum negative pressure. The working temperature in the extraction tank is controlled at 60-80 ℃, and the concentration temperature is controlled at 50-70 ℃, ensuring that the effective components of traditional Chinese medicine are not evaporated and lost. At the same time, the steam generated from extraction and concentration is condensed by a heat exchanger and refluxed to the extraction tank, where it is added as a new solvent to the medicinal herbs. The new solvent passes through the layer of medicinal herbs from top to bottom, playing a dynamic percolation role. The soluble substances that dissolve the medicinal herbs reach the bottom of the extraction tank and enter the concentrator for concentration. Based on years of practice and research, under the action of vacuum low-temperature vaporization heat, the larger the concentration difference, the higher the extraction rate of effective ingredients. The refluxed hot condensate should be replaced with all the original solvents in the extraction tank at an appropriate time according to the corresponding model specifications, so that the solutes in the medicinal tissue and the solutes in the leachate in the extraction tank can maintain a high concentration difference per unit time.
