Aapplication:
It is suitable fortraditional Chinese medicine, plant, animal, food, chemical and some otherindustries, in addition to frankincense, rosin, aloe and other non medicinaltissue for they soften into a group when contact solvent, the pores would beblocked so that the solvent can not go evenly through the medicine, not suitablefor percolate, other medicines can be used with this method.
Working principle：
The percolationmethod is to continuously add dipped solvent to herbs coarse powder for theinfiltration of powder, percolation tank from the lower end of the outlet of aleaching method for leaching liquid. When percolation,soluble substances, solvent into cells in a large number of drug ,so concentrationincreases, and the density increases while moving downward, the upper leachingsolvent replaces dilute extract position, resulting in good concentrationdifference, the diffusion is easy to perform, so the leaching effect is betterthan impregnation method, extraction is complete.
Structure andcharacteristics:
The equipment containsa cylinder, cone, oval head (or flat cover) and pneumatic slag gate, which hasthe characteristics of solvent even distribution and convenient slag discharge.
