Abstract
The utility model provides a production device for decoloring a crude product of vitamin B6. The production device is characterized by comprising a tubular membrane filtering system, wherein the tubular membrane filtering system comprises an ultrafiltration membrane core arranged inside the tubular membrane filtering system, a decoloring stock solution feed port formed in one end of the ultrafiltration membrane core, a concentrated solution discharge port formed in the other end of the ultrafiltration membrane core, and a decoloring solution discharge port formed in the outer layer of the tubular membrane filtering system. By using the production device, the decoloring efficiency is improved, the production cycle is shortened, the stability of the product quality is good, the labor intensity is reduced, and the utilization rate of equipment is high.
Description
Technical field
The utility model relates to the vitamin production technical field, particularly a kind of for Cobastab
6The process units of crude product decolouring.
Background technology
Cobastab
6(Vitamin B
6) claim again pyridoxine, be a kind of water soluble vitamin, be white crystal, soluble in water and ethanol, stable in acid solution, meet light or alkali destructible, non-refractory.Cobastab
6In saccharomycete, liver, grain, meat, fish, egg, beans and peanut, content is more, is the constituent of some coenzyme in human body, participates in multiple metabolic response, especially with amino acid metabolism, substantial connection is arranged.Apply clinically Cobastab
6The preparation control vomiting of pregnancy and radiation sickness vomiting.
At present, industrial common employing chemical synthesis is produced Cobastab
6, the process route of realizing suitability for industrialized production has two kinds of pyridone method and oxazole methods." pyridone method " is that early stage industry adopts, and because of defects such as step are long, yield is low, equipment corrosion is serious, is leveraged to the sixties in 20th century afterwards, by " oxazole method ", replaced gradually.
Because the reaction temperature of oxazole operation is higher, cause producing the more impurity such as tar, the Cobastab of production
6The crude product color is darker, needs could remove through 2-3 activated carbon decolorizing, and traditional handicraft is carried out in reactor, Cobastab
6Add appropriate active carbon in crude product solution, after the mechanical agitation certain hour, blowing is through the centrifuge decarburization, and filtrate is so repeatedly decoloured and repeatedly just can be reached requirement again.
Yet, the mode of production like this, be difficult to ensure colored foreign and reach fully and remove at short notice, thus under this kind of mode of production 2-3 time even repeatedly repetitive operation be unavoidable, there is long, the shortcoming such as utilization rate of equipment and installations is low of cycle, and increased Cobastab
6The risk that crude product is rotten.Make like this competitiveness of product in market descend.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of for Cobastab
6The process units of crude product decolouring, improve decolorizing efficiency, shortens the production cycle, and constant product quality is good.
It is a kind of for Cobastab that the utility model provides
