Decolorizing device for decolorizing and purifying aminobutyric acid fermentation liquor

Abstract

The invention relates to the field of fermentation and filtration, and particularly discloses a decolorizing device for decolorizing and purifying aminobutyric acid fermentation liquor, which comprises a shell, a plurality of decolorizing pipes arranged in the shell, filters for filling the decolorizing pipes, a water bath module, a liquid inlet and a liquid outlet, wherein the interior of the shell is divided into three layers; the water bath module heats the decolorizing pipes located in the middle layer of the shell in a water bath mode, liquid needing to be filtered flows to the lower layer of the shell from the upper layer of the shell through the decolorizing pipes, and filtered matter comprises activated carbon and NH2-UiO-66. According to the scheme, the temperature in the decolorization process can be stabilized in a water bath mode, interference of the external environment is reduced, and separation and purification stability, efficiency and quality are improved; the decolorizing pipe is detachably mounted, so that the device is convenient to replace and maintain; the decolorizing pipe is filled with a novel mixture, and an optimal mixing ratio is provided, so that the decolorizing rate can be increased, and the loss rate can be reduced.

Description

technical field [0001] The invention belongs to the technical field of fermentation and filtration, in particular to a decolorization device for decolorization and purification of GABA fermentation liquid. Background technique [0002] Aminobutyric acid widely exists in nature and is a natural amino acid composed of non-proteins. It is the most important inhibitory neurotransmitter in the central nervous system of mammals and has regulatory effects on various functions of the body, such as reducing Blood pressure, treatment of epilepsy, anti-aging, enhancement of brain vitality, improvement of menopausal syndrome and other physiological functions. Therefore, GABA, as a new type of functional factor, is widely used in the fields of medicine, food, health care, chemical industry and agriculture. [0003] At present, the preparation process of GABA is mainly divided into chemical method and biological method. The biological method includes plant enrichment method and microbial...

AI Technical Summary

Problems solved by technology

[0005] 1. The aminobutyric acid in the fermentation broth is adsorbed at the same time, and the loss rate is large; 2. It is sensitive to temperature, so it needs to be decolorized at a suitable constant temperature, and the reported decolorization and purification devices for the GABA fermentation broth rarely carry out condition control, especially There is no temperature control, and it is easily disturbed by the ambient temperature, resulting in poor separation and purification effect and low efficiency
