percolating tank

The percolation extraction tank is an equipment used for dipping and percolation in traditional Chinese medicine factories. In this process, it can extract alcohol and soak it. It adopts metered feed and liquid metering flow control to dissolve the drug liquid in different gradients. This equipment is in contact with the drug. All are made of stainless steel, so this equipment has good corrosion resistance, which not only ensures the quality of traditional Chinese medicine products, but also has a long service life. During the percolation process, this equipment is completely immersed in the organic solvent or water and medicine. It is completed in a completely sealed and recyclable system, and the organic solvent can be recovered from the waste residue. This equipment complies with GMP certification requirements and is suitable for alcohol extraction, percolation and soaking.

Percolation tank, main configuration of percolation extraction tank

1. This set of equipment of the percolation extraction unit includes: percolation main tank, high level tank, percolation liquid receiving tank and internal connecting pipes;

2. The percolation tank is a slender four-lug suspension type with a pneumatic slag discharge door. The material of the contact surface between the equipment and the pharmaceutical industry is s30408; the design pressure is normal pressure.

3. High level tank: material is s30408; design pressure is normal pressure.

4. Leachate receiving tank: made of s30408; design pressure is normal pressure.

5. Equipped with operating platform as required: made of stainless steel.

6. Internal connecting pipes, made of s30408,

7. The inner wall of the equipment container is mirror polished, and the outer surface is mirror or matt treated, complying with GMPFDA certification standards.

Working principle of percolating tank

The solvent and Chinese medicine are put into the extraction tank, soaked for several hours (as specified by the process requirements), the liquid into the storage tank, the solvent flows into the percolation tank at a constant speed through the flow control, and then the liquid is returned to the high tank through the pump; The original alcohol can also be filled into the extraction tank according to the relevant requirements, and this cycle is repeated several times until the active ingredients of the liquid medicine are leached out.
