a bioreactor

Abstract

The invention provides a bioreaction tank, and belongs to the technical field of biochemistry. The problem of low reaction speed in the prior art is solved. The bioreaction tank comprises a tank body, wherein the tank body is cylindrical, an upper sealing head is arranged at the upper end of the tank body, a lower sealing head is arranged at the lower end of the tank body, each of the upper and lower sealing heads is semispherical, a first opening is formed in the top end of the upper sealing head, a second opening is formed in the bottom end of the lower sealing head, a stirring mechanism capable of increasing the reaction speed of a reaction solution is arranged between the upper and lower sealing heads, a monitoring port is formed in one side of the upper sealing head, an end cover is hinged to one side of the monitoring port, a sampling port is formed in the other side of the upper sealing head, a sampling pipe is arranged in the sampling port, a cooling mechanism capable of cooling the reaction solution in the tank body is further arranged on the outer side of the lower half part of the tank body, a heating mechanism capable of heating the reaction solution is further arranged on the inner wall of the tank body, a feed opening is further formed in one side of the tank body, and an air outlet is further formed in the other side of the tank body. The bioreaction tank has the advantage that the reaction speed of the reaction solution is increased.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and relates to a reaction tank, in particular to a biological reaction tank. Background technique [0002] The Chinese aliases of nicotinamide are: nicotinamide, vitamin B3 (VB3), nicotinamide, 3-pyridinecarboxamide, the English name is nicotinamide, the molecular formula is C6H6N2O, the molecular weight is 122.13, it is a white needle-like crystal or powder, and it belongs to the vitamin B family. As a kind of B vitamins, nicotinamide is an important part of coenzyme I and coenzyme II in human and animal bodies, and participates in lipid metabolism, the oxidation process of tissue respiration and the process of anaerobic decomposition of carbohydrates. It is a component of dehydrogenation coenzymes in living organisms, which can promote the biological oxidation process and tissue metabolism, and play an important role in maintaining the integrity of normal tissues (especially the skin, dige...

AI Technical Summary

Problems solved by technology

[0003] The production process of nicotinamide is as follows: biocatalyst cultivation (production of strains-seed tank-fermentation tank-membrane separation) and biocatalytic reaction and post-treatment (catalyzed hydration reaction-membrane separation ultrafiltration-concentration-granulation- Drying-screening); Catalyzed hydration reaction This process is to put deionized water, nicotine nitrile, biocatalyst aqueous solution and other substances into the bioreactor for reaction. The structure of the existing bioreactor is relatively simple, and the temperature can only be lowered and cannot be heated up. , when different processes are used, the reaction temperature is different, resulting in the inability to quickly adjust the reaction temperature to the optimum, resulting in the problem of low reaction efficiency
