Device suitable for mixed fermentation of various microorganisms

Abstract

The invention belongs to the field of fermentation devices, and particularly discloses a device suitable for mixed fermentation of various microorganisms, the device comprises a first fermentation module, a second fermentation module, a sealed stirring device and a connecting filtering device, the sealed stirring device comprises an adjusting ring, a connecting cross rod, a fixing rod, a sealing plate and stirring blades, the connecting and filtering device comprises a sleeve provided with a diaphragm layer, and the first fermentation module and the second fermentation module are detachably connected through the sleeve. According to the device, the uniformity of fermentation liquor is ensured, and meanwhile, a customized filter membrane is replaced according to the size of inoculated microorganisms, so that physical isolation of different strains can be realized, and the problems that the survival rate of non-dominant strains is difficult to ensure due to mutual killing or inhibition when an existing liquid fermentation device is used for fermenting mixed strains are solved; meanwhile, the problems of inconvenience in replacement of a filter membrane, easiness in leakage or pollution, non-uniform stirring in the fermentation process, incapability of realizing multi-channel mixed fermentation and the like in the existing fermentation device can be solved, and the control of a multi-strain mixed fermentation process is facilitated.

Description

technical field [0001] The invention belongs to the field of brewing and fermentation devices, in particular to a device suitable for mixed fermentation of various microorganisms. Background technique [0002] Wine making is the process of using microorganisms to ferment and produce alcoholic beverages with a certain concentration. In order to improve the flavor of wine, researchers are constantly trying to use mixed strains of fermentation to improve the complexity of the flavor of fermented wine by controlling the physiological and biochemical processes of different species of microbial fermentation. In particular, the introduction of non-dominant populations of non-Saccharomyces cerevisiae into the fermentation system with Saccharomyces cerevisiae as the dominant species can effectively improve the complexity of flavor. However, the existing liquid fermentation devices can only achieve simple mixing. The inoculum and fermentation broth exist in the same fermentation space...

AI Technical Summary

Problems solved by technology

However, there is still no relatively mature mixed fermentation device at present, and there are still problems such as inconvenient replacement of filter paper and easy leakage, etc., and generally only simple mixing of two barrels can be realized, multi-channel liquid mixing cannot be realized, and the mixing is not uniform enough
