Problems solved by technology

The extraction tank has the following disadvantages: during the extraction process, the solvent and the material are sealed in the tank and extracted by soaking, the material is static, and the extraction rate is low; the extraction tank works intermittently instead of continuously, so the processing capacity is relatively low ;The feeding door needs to be opened when feeding the extraction tank, and the quick-opening cover needs to be opened when discharging the material, which

Abstract

The invention discloses a countercurrent extractor, which comprises a tank body, a base, a rotating body, a detachable door, liquid collection hoppers, an inner rail, an outer rail, and an electric driving mechanism, wherein the tank body is provided with a solvent inlet, an extracting solution outlet, a material inlet and a material outlet; the rotating body is rotatablely arranged in the tank body; a plurality of the liquid collection hoppers are arranged below the detachable door and are arranged in a mode of ensuring that the liquid level height of the liquid collection hoppers is in a stepped gradual reduction mode, and the direction of gradual reduction is opposite to the direction of the rotation of the rotating body; a liquid outlet of the liquid collection hopper of the lowest liquid level is connected with the extracting solution outlet of the tank body; and the electric driving mechanism is used for driving the rotating body to rotate. Compared with the prior art, the countercurrent extractor has the advantages of completely continuous extraction process, large production capacity, full automaticity and no need of manual operation, fully closed equipment and no any leakage.

Description

technical field [0001] The invention relates to an extractor, more specifically, an extraction device for active ingredients in natural plants or medicinal materials. Background technique [0002] The extraction of active ingredients of pharmaceutical intermediates or the extraction of active ingredients of natural plants uses various extraction tanks and countercurrent extraction machines. [0003] The use of extraction tanks to extract the active ingredients of medicinal materials is widely used in the pharmaceutical industry. In the extraction tank, the medicinal materials are mixed with a certain proportion of solvent, soaked at the temperature required by the process, and the extraction mixture is extracted after the time is up to complete an extraction process. The conventional extraction process is two extractions, the process includes: adding materials, adding solvent and water according to the proportion of the process requirements, heating and heat preservation acc...
