This equipment is suitable for percolation operation of traditional Chinese medicine, food, chemical industry and other industries.
The equipment is composed of cylinder, lower cone, elliptical head (or flat cover), liquid distributor, pneumatic slag discharging door, pneumatic operation platform, etc. it has the characteristics of uniform solvent distribution and convenient slag discharge.
Percolation is a kind of leaching method in which the extraction solvent is continuously added to the medicinal materials to make it seep through the medicinal materials and the leaching liquid flows out from the lower outlet. When leakage occurs, the solvent dissolves a large amount of soluble substances through the medicinal material layer from top to bottom. The concentration increases and the density increases, and then it moves downward. The upper layer of the leaching solvent or dilute extract replaces the position, resulting in a good concentration difference, which makes the diffusion better and natural. Therefore, the leaching effect is better than the immersion method, and the extraction is more complete.
