Detailed description

product description
The percolation method is a leaching method in which a solvent is continuously added to the coarse powder of the medicinal material so as to permeate the medicament to flow out the leaching solution from the lower end outlet. When the solvent penetrates into the cells of the medicinal herbs, it dissolves a large amount of soluble substances, the concentration increases, the density increases, and the upper leaching solvent or dilute solution displaces the position, resulting in a good concentration difference, The natural leaching effect is better than the impregnation method, the extraction is more complete, but also eliminates the separation of the operating time of the leaching solution.
Continuous addition of new solvent from the top of the tank, continuous discharge from the bottom of the percolation liquid extraction components, are dynamic extraction equipment. As the active ingredient leaching completely, without filtration, can be directly collected percolate, it is widely used in precious herbs, toxic herbs, high concentrations of active ingredients and formulations of low extraction of herbs.
Structural features
The equipment mainly consists of cylinder, cone, oval head (or flat cover), spray pipe, pneumatic slag door, pneumatic console and other components, with a solvent distribution, slag to facilitate and so on. Solvent spray through the upper part of the tank evenly sprinkled on the medicine. The active ingredient of the medicinal material is dissolved in the solvent by immersion.
1. The slag door with ordinary double-cylinder open-close or three-cylinder rotary. The rotary safety door adopts single cylinder opening and closing, double cylinder rotation push locking, wedge self-locking, completely solve the compressed air supply pressure instability caused by leakage or decoupling accident, the use of high safety factor.
2. Equipped with herbs pressing device to prevent herbs floating and herbs pollution.
Scope of application
This equipment is suitable for the seepage operation of traditional Chinese medicine, plants, animals, food, chemical industry, etc. In addition, the non-tissue herbs such as frankincense, rosin and aloe will block the pores so that the solvent can not evenly pass the medicine, With percolation, the other herbs can be used this method leaching.
