[0002] Gamma-aminobutyric acid (GABA) is a naturally occurring non-protein amino acid, widely exists in vertebrates, plants and microorganisms, is a white crystalline powder and is easily soluble in water; it has been artificially synthesized as early as 1883, and was found to exist in nerve tissue in 1950, and its direct precursor is glutamic acid, which is generated by decarboxylation of glutamic acid by glutamate decarboxylase;

[0003] Gamma-aminobutyric acid has many physiological functions such as lowering blood pressure, treating epilepsy, calming nerves, enhancing memory, improving liver function, and improving liver and kidney function, and is widely used in food and medicine. At present, the research on GABA-rich food has become one of the current research hotspots; early gamma-aminobutyric acid adopts chemical synthesis method, but the cost is high, the yield is low, and it cannot be applied to food industry because dangerous solvents are used in production. Now GABA is produced by biological synthesis method, which has the advantages of low cost, high content and safe use, and is increasingly widely used in food industry. However, the separation and purification of GABA fermentation broth is the key link to realize its industrial production;

[0004] Traditional gamma-aminobutyric acid purification has many problems; on the one hand, when the gamma-aminobutyric acid is purified at present, the steps are complicated and the operation is troublesome, which greatly reduces the purification effect and affects the production efficiency and product quality; on the other hand, in the aspect of separation and impurity removal, there is a lack of effective means to remove impurities such as filamentous and flocculent materials formed by fermentation residues, colloids or precipitates formed by incomplete conversion of substrates, and metal particles mixed from the environment, which is difficult to meet the requirements of industrial production for high purity of gamma-aminobutyric acid. UTILITY MODEL CONTENT

[0005] In order to solve the problems existing in the traditional gamma-aminobutyric acid purification in the prior art, the utility model provides a gamma-aminobutyric acid separation and impurity removal equipment;

[0010] Further, the bottom of the top cover is detachably provided with a flow impact plate; the flow impact plate is a cylindrical structure and is arranged outside the centrifugal tank; a plurality of hooks for hanging the filamentous impurities are welded on the inside wall of the flow impact plate;

[0011] Further, the filter assembly comprises a filter pipe, a first filter membrane and a second filter membrane; the bottom of the feed tank is through-welded with a connecting pipe; the bottom of the connecting pipe is threadedly connected with the filter pipe and is sealed through a sealing ring; the inside wall of the filter pipe is detachably connected with the first filter membrane and the second filter membrane from top to bottom;

[0015] In summary, the beneficial effects of the centrifugal assembly are as follows:

[0016] The centrifugal assembly is high-speed rotated to generate a strong centrifugal force, so that the filamentous and flocculent impurities in the γ-aminobutyric acid solution are effectively thrown to the inside wall of the centrifugal tank, and then the hooks on the flow impact plate are combined to intercept the filamentous impurities which are not completely removed, so that the high-efficiency removal of the impurities in the fermentation residues is realized; compared with the traditional filtering mode, the method combining the centrifugal force and the physical interception has higher removal efficiency and can significantly reduce the content of the impurities in the product.

[0017] The filtering assembly adopts a two-stage filtering design, a nylon membrane with a filtering aperture of 5 mu m is used to first intercept larger colloidal or precipitated impurities, and then a ceramic membrane with a filtering aperture of 0.45 mu m is used to further filter smaller impurity particles; this grading filtering mode can purify the solution more finely, effectively solves the problem that small impurities may be left over in the traditional single filtering mode, and greatly improves the purity of the gamma-aminobutyric acid product;

[0018] The metal impurity treatment assembly uses a magnetic field generated by an electromagnetic coil to adsorb metal ions in the solution, and the spiral channel structure in the metal treatment pipe increases the contact area and time of the solution with the magnetic field, so that the metal ions are fully adsorbed; this solves the problem that metal impurities are difficult to be effectively removed in the traditional process, and avoids the influence of metal ions on the product quality and safety.
