Abstract

The present invention provides a soluble component by a special liquid extracting in solid matters, or another soluble component by solution is separated from a soluble solution, and proceeding synchronous concentration to extracting solution at the same time. The invention has an extracting container, located in a feed inlet, a sealing lid on the extracting container, and a mixing device in the extracting container, and a taphole and an outlet on the extracting container. The device also has a concentrating container with a heating device, the upper of the concentrating container is set with a pipeline connected with the condenser, end of the condenser uses the inner of the extracting container of another pipeline, the outlet of the downstream is located above the 2 / 3 of the inner height if the concentrating container.

Description

technical field [0001] The present invention relates to an extraction device, which can be used to extract components of solid matter which can be dissolved by a specific solution, and can also be used to separate components which are dissolved in one solution and which can be dissolved by another solution, And the extract can be concentrated simultaneously. The invention is particularly suitable for extracting specific components of traditional Chinese medicines. The invention comprises an extraction container, a heating device arranged on the extraction container, a feeding port and a sealable cover located on the extraction container, a stirring device located in the extraction container, and a liquid outlet and a slag outlet arranged on the extraction container. Background technique [0002] At present, the commonly used extraction methods of traditional Chinese medicine include decoction, reflux, maceration, percolation, etc. New extraction techniques include supercrit...
