The countercurrent method is a universal method of continuous and thorough contact extraction in which medicinal materials and solvents move in opposite directions in an extraction container. The equipment is an efficient continuous dynamic countercurrent extraction machine, and its extraction principle is to use a heating method with strong microwave penetration to make extraction faster and more convenient. Continuous countercurrent extraction equipment is a combination of dynamic extraction, countercurrent extraction, and decoction extraction processes. While retaining the advantages of various traditional processes, it creates many advantages that cannot be achieved by these traditional processes: fast extraction speed, sufficient extraction of effective ingredients, high extraction yield, low solvent consumption, high drug concentration, reduced subsequent processing such as evaporation and concentration. The movement speed of medicinal particles in the drum can be adjusted to adjust the extraction time according to the characteristics of the medicinal materials. The medicinal materials are extracted in a mild dynamic environment with low heating temperature and less damage to effective ingredients, resulting in less impurities in the medicinal materials. It belongs to continuous production and has a large processing capacity.
This countercurrent extraction is composed of a feeding hopper, a rotary extraction cylinder, and a slag discharge screw conveyor. After rough crushing and soaking, the raw materials are fed into the hopper, and the extraction cylinder rotates. At the same time, the spiral belt fixed on the inner wall of the extraction cylinder slowly pushes the material backwards from the front end of the unit. At the same time, the extraction solvent enters the extraction cylinder from the inlet pipe at the end of the unit and flows through the moving material from the back end of the cylinder to the front end. The solid-liquid two-phase substances fully contact each other in this reverse motion, thereby extracting the effective ingredients from the medicinal materials. The medicinal residue is forcibly pushed to the slag outlet by the slag discharge screw conveyor and discharged. The slag discharge screw simultaneously squeezes the medicinal residue, squeezing out the residual medicinal solution from the medicinal tissue and reducing the residual medicinal solution content.
