Crystallizing tank for extracting hyodeoxycholic acid

Abstract

The invention discloses a crystallizing tank for extracting hyodeoxycholic acid, which comprises a reaction tank and a crystallizing cabin mounted below the reaction tank, a plurality of crystallizing plates are obliquely arranged in the crystallizing cabin, hot gas discharged by the reaction tank is conveyed into the crystallizing plates after being secondarily heated, the reaction tank discharges liquid in a water curtain shape, and the crystallizing cabin is communicated with the crystallizing plates. And the liquid flows along the inclined direction of the crystallization plate and is heated to evaporate and crystallize. According to the crystallizing tank for extracting hyodeoxycholic acid provided by the invention, the crystallizing plate is filled with high-temperature steam, so that high temperature is attached to the surface of the crystallizing plate, liquid in contact with the surface of the crystallizing plate can be evaporated in an extremely short time, hyodeoxycholic acid contained in the liquid can form crystals, and the whole crystals are more convenient to extract; the previous tedious crystallization extraction steps are reduced; and the device recycles and heats steam flowing in the reaction tank, the crystallization cabin and the crystallization plate, so that resources consumed by heat energy provided for heating the crystallization plate are reduced.

Description

technical field [0001] The invention relates to crystallizing tank equipment, in particular to a crystallizing tank for hyodeoxycholic acid extraction. Background technique [0002] Hyodeoxycholic acid is a cholanoic acid extracted from pig bile, and its appearance is white or slightly yellowish powder. It has good blood cholesterol and triglyceride lowering and bacteriostatic effects, and can also be used as an anti-inflammatory drug to treat chronic bronchitis, viral upper respiratory tract inflammation in children, etc., and has great medicinal value. [0003] According to the patent number CN201410496041.4, the date of publication (announcement): 2016-08-24, the disclosed method for extracting hyodeoxycholic acid, the HDCA production method of the invention has a relatively low cost, can form industrialized large-scale production, and the obtained products The purity is high, and the total yield reaches more than 20% of the input leftover material; the invention overcom...

Problems solved by technology

However, the extraction steps of this kind of crystals are too cumbersome. If the evaporation method is used, the crystals can also be obtained, and the crystallization steps are greatly reduced, and the production efficiency is increased.
