Scope: This equipment is suitable for medicine, plants, animals, food, chemical and other industries percolation operations, except frankincense, rosin, organizations and other non-medicinal aloe solvent to soften due to the case of a corporation, can clog the pores of the solvent can not be evenly through herbs rather it is appropriate percolation, other herbs can leach method has been applied. Products: percolation method is to continually add herbs meal solvent leaching it seeps through the powder, a method of leaching out of the leach solution from the lower end of the exit. When percolation, solvents penetrate cells herbs in a large number of the solution after the contents of soluble substances, concentration, density increases and moves down, the upper extraction solvent or dilute infusion replacement position, form a good concentration difference, the diffusion Jiao The natural good conduct, it is better than invasion maceration, extraction is also more secure. Features: 1. percolation tank bottom valve with a large aperture to slag, can be easily removed dregs. 2. The inner tank: mirror polished inner surface roughness Ra <0.6μm; 3. the device can be equipped with a heating system to facilitate a variety of materials and laboratory solvent extraction of percolation. The shell surface treatment: mirror polishing inside the tank, no health corners, outside the tank 2B, brushed. 5. Material: Stainless steel SUS304 or SUS316L; 6. The device can be configured to automatically add the solvent system, to facilitate quantitative timing solvent added. 7. The device is suitable for medicine, plants, animals, food, chemical and other industries laboratory in small quantities percolation operation, in addition to frankincense, rosin, organizations and other non-medicinal aloe can clog the pores of the solvent can not be evenly through herbs, should not use infiltration Luk extraction, other ingredients can leach method has been applied. 8. After the experiment, the concentration increases, the density increases and the downward movement, the upper or dilute immersion leaching solvent replacement bits.
