Description

Technical Field

[0001] The utility model relates to the technical field of decolorization devices, in particular to an activated carbon decolorization device used for silybin purification. Background Art

[0002] Silybin is a flavonoid compound extracted and separated from the fruit of the Asteraceae plant Silybum marianum. It has obvious effects of protecting and stabilizing liver cell membranes, improving liver function, producing an enzyme-lowering effect, and is not prone to enzyme rebound.

[0003] Silybin is usually extracted at room temperature by mixing silybin seed cake with ethanol. The extracted solution is a colored solution and needs to be decolorized to facilitate the subsequent refining process. Currently, activated carbon decolorization equipment is mostly used for the refining and decolorization of silybin. The raw material solution and activated carbon powder are put into the decolorization tank in proportion and mixed evenly. The adsorption capacity of the activated carbon is used to absorb the color in the solution. However, there are some functional deficiencies in actual use and there is room for improvement. For example, when the activated carbon is mixed with the ethanol solution containing silybin, the lightweight activated carbon powder easily floats on the surface of the solution, requiring a long time of stirring and mixing, which is inefficient and does not have the function of facilitating rapid mixing.

[0004] Now, a new activated carbon decolorization device for silybin purification is proposed to solve the above problems. Utility Model Content

The decolorization state of the solution can be intuitively understood through the transparent window 26.
