HR-PF12 Stainless steel percolation leaching tank

Equipment Overview:

Percolation tank is suitable for percolation operation in traditional Chinese medicine, plants, animals, food, chemical industry, etc. In addition to frankincense, rosin, aloe vera and other non-organized herbs due to the solvent softened into a mass, will block the pore so that the solvent can not be uniformly through the herbs, and should not be used for percolation, other herbs can be used in this method of leaching.

Working principle of percolation tank:

 Percolation tank (Chinese medicine percolation tank extraction alcohol precipitation tank): percolation method is suitable for pharmaceutical production. Percolation method is to add to the crude powder of herbs in the extraction of solvents to make it penetrate through the powder, from the lower end of the exit out of the extraction of a method of extraction. Percolation, the solvent penetrates into the cells of the herb to dissolve a large number of soluble substances, the concentration increases, the density increases and moves downward, the upper layer of the leaching solvent or dilute leaching solution to replace the position, resulting in a good concentration difference, so that the diffusion of a better natural, so the effect of leaching is better than the impregnation method, and eliminates the need for separation of leaching liquid operation time.
