purpose
This equipment is suitable for percolation operations in industries such as traditional Chinese medicine, plants, animals, food, and chemicals. Except for non organic medicinal herbs such as frankincense, rosin, and aloe vera, which soften into clumps when in contact with solvents and block the pores, making it difficult for the solvent to pass evenly through the herbs and not suitable for percolation, this method can be used to extract other medicinal herbs.
structure and characteristics
This equipment consists of simplified, conical, elliptical head (or flat cover), pneumatic slag gate, pneumatic operation platform, etc. It has the characteristics of uniform solvent distribution and convenient slag removal.
Working principle
The percolation method is a method of leaching in which a solvent is continuously added to the crude powder of medicinal herbs to allow it to permeate through the powder, and the leaching solution flows out from the lower outlet. During percolation, the solvent infiltrates into the cells of the medicinal material and dissolves a large amount of soluble substances. As the concentration increases and the density increases, it moves downwards. The upper layer of leaching solvent or dilute leaching solution replaces the position, creating a good concentration difference and allowing diffusion to occur naturally. Therefore, the leaching effect is better than the leaching method, and the extraction is also more efficient, saving the operation time of separating the leaching solution.
