Abstract

The invention discloses a drug extraction device for improving percolation effect, which comprises a device body, a lifting cylinder is arranged on the top of the device body, a feeding part is arranged on the left side of the device body, and a lifting rod connected with the lifting cylinder is arranged in the device body. The upper part of the lifting rod is connected with a solvent feeding channel, the inlet end of the solvent feeding channel is set outside the device body, and the outlet end is set inside the device body; the lower part of the lifting rod is connected with a filter plate, and the lower part of the device body is provided with a discharge port , the solvent feeding channel is provided with a sliding device, and the lifting rod is provided with a guide rail for the sliding device to slide along the long axis of the lifting rod. The present invention sets the solvent feeding channel so that it can move up and down along the lifting rod, so as to flatten the medicinal material, solve the problem of too long time for very small medicinal material particles to float to the surface of the solvent, and improve the quality and effect of percolation .

Description

technical field [0001] The invention relates to the field of medicine extraction, in particular to a medicine extraction device for improving percolation effect. Background technique [0002] The percolation method is to put the moderately crushed medicinal materials in the percolation cylinder, continuously add solvent from the upper part, and leach the medicinal ingredients during the process of the solvent seeping through the medicinal material layer and flowing downward. Percolation is a dynamic leaching method with high solvent utilization rate, complete leaching of active ingredients, and direct collection of leachate. It is suitable for precious medicinal materials, toxic medicinal materials and high-concentration preparations; it can also be used for the extraction of medicinal materials with low active ingredient content. However, it is not suitable for fresh and swellable medicinal materials and medicinal materials without organizational structure. In this method...
