Nicotinamide dilute solution decolorizing device and method

Abstract

The invention discloses a nicotinamide dilute solution decolorizing device and method. The nicotinamide dilute solution decolorizing device comprises a decolorizing treatment box, the upper end of thedecolorizing treatment box is provided with a liquid hopper, the bottom of the liquid hopper extends into the decolorizing treatment box, and the decolorizing treatment box is internally provided with a decolorizing treatment tank and a reserved filtrate storage bin. According to the nicotinamide dilute solution decolorizing device and method, the nicotinamide dilute solution is decolorized and filtered through the activated carbon particles filled in the charging barrel, and when activated carbon adsorption is saturated, the activated carbon is replaced by rotating a hand wheel, so that a new round of activated carbon decolorizing and filtering is realized; as frequent shutdown is not needed when the activated carbon is replaced, the activated carbon decolorizing device has the advantages of simplicity in operation and convenience in use, thereby greatly shortening the decolorizing time of the feed liquid and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of a vitamin solution decolorization device, in particular to a dilute nicotinamide solution decolorization device and method. Background technique [0002] Niacinamide, also known as nicotinamide, is an amide compound of niacin. It is white crystalline powder; odorless or almost odorless, bitter; slightly hygroscopic. Soluble in water or ethanol, soluble in glycerin. Niacinamide is one of the indispensable nutrients for the growth and development of humans and animals. It participates in the formation of important coenzymes, promotes metabolism, and has a wide range of uses in hospitals, feed and food. [0003] In the fields of food, medicine and chemical industry, powdered activated carbon is often used to decolorize and filter products to improve product purity and color. The existing decolorization method is to add powdered activated carbon to the feed liquid to be decolorized, and use activated carbo...

AI Technical Summary

Problems solved by technology

The existing decolorization method is to add powdered activated carbon to the feed liquid to be decolorized, and use activated carbon to perform adsorption and decolorization. However, due to the one-time filling of powdered activated carbon, it is very inconvenient to stop the work frequently to replace the activated carbon after the activated carbon is saturated. , and increase the decolorization time of the feed liquid, resulting in low production efficiency
