Usage: The SLG Seeping Tank is applicable for the filtration operation for such industries as traditional Chinese mendicine, food and chemical industry etc.

Working principle: The filtration method is to add continuously leaching solvent into the rough powder of medicine material to make it filtrate the medicine powder, and then the leaching liquid will flow from the bottom outlet. During the filtration, the solvent will filter into the cell of medicine material to dissolve large amount of soluble matter. The concentration increases, and it will move downward after the density increases. The leaching solvent at the upper layer or the thin leaching liquid will exchange the position and produce good concentration difference to make the scattering be carried out smoothly. Thus, the leaching effect is better than the dipping method, and the extraction will be comparatively complete.

Strucure features : The equipment is composed of tank body, taper body, oval seal head(or flat cover), pneumatic slagging door and pneumatic operation bench etc. It has such characteristics as equal solvent distribution and convenient slagging etc.
