AI Technical Summary

Technical Problem

In the existing process of concentrating mongholic acid extract, impurities are easily enriched, resulting in turbidity of the concentrate, which increases the difficulty of separation and makes it impossible to use it directly in formulation. Furthermore, unfiltered impurities lose stability after concentration and are prone to precipitation.

Method used

The extraction tank with heating function and multi-stage filtration system are adopted, including stirring mechanism, concentration tube and multiple filter elements. Impurities are removed by heating and stirring and multi-stage filtration to ensure the clarity of the concentrate and prevent impurities from precipitating.

Benefits of technology

It achieves the maintenance of the clarity of the concentrate, reduces the difficulty of the separation steps and reagent consumption, improves the efficiency of subsequent separation steps, meets the clarity requirements of the formulation, and avoids rework.

Abstract

This utility model discloses a device for concentrating the extract of strychnine from cold medicine granules, including an extraction tank with a heating function, a tank cover, and an extraction stirring mechanism on the tank cover. The extraction stirring mechanism stirs the extract in the extraction tank. The extraction tank is equipped with a concentration tube, and the concentration tube is connected to a concentration filtration mechanism. The concentration filtration mechanism includes a concentration cylinder connected to the concentration tube and a first filter element, a second filter element, a third filter element, and a fourth filter element arranged sequentially in the concentration cylinder. This utility model uses the first, second, third, and fourth filter elements in the concentration cylinder to filter and remove impurities from the concentrated liquid, intercepting impurities in stages and solving the separation problem: through the filter elements with decreasing pore size, medicinal residue, fibers, colloids, and fine particles are sequentially intercepted, preventing impurities from agglomerating as the viscosity of the concentrated liquid increases. This improves the efficiency of subsequent separation steps (such as alcohol precipitation and chromatography) and reduces reagent consumption.
