Full-automatic dynamic solid-liquid separation extractor

Abstract

The invention discloses a full-automatic dynamic solid-liquid separation extractor comprising an extracting tank, a temporary storage tank of extract, a heat exchanger, a temperature control device of the heat exchanger, a gas-liquid separator, a recovered solvent condenser and a computer control system, wherein the extracting tank is in inverted cone shape; the upper part of a tank body is provided with a feed hopper and an upper liquid in-out port, and the bottom of the tank body is provided with an automatic deslagging door which is provided with a lower liquid in-out port; the upper part of the liquid in-out port of the automatic deslagging door is provided with a metal screen; and the extracting tank, the temporary storage tank and the heat exchanger form the external recycle system of extract by a circulating pump and a pipeline. The whole working process is finished by a computer control system. An external automatic control and circulation system of extract temperature is used to quickly heat extract in the extracting tank to the required extracting temperature to automatically keep temperature; concentration difference between material and extract liquor is minimized so as to effectively avoid the problems of overheating, coking, binding and the like which are produced by direct contact of solid material and heating surface and are unfavorable for extract quality. The invention has the advantages of high extraction efficiency, high leaching speed, high complete-extraction rate of effective ingredient, small draining coefficient, low-temperature leaching, even heating, energy saving and the like.

Description

technical field [0001] The invention relates to an extraction device for solid-liquid separation, in particular to a fully automatic dynamic solid-liquid separation extraction device, which is suitable for the extraction of effective components of solid materials such as traditional Chinese medicine, food and beverages.
