Mixed fermentation device for liquid state fermentation in laboratory

Abstract

The invention discloses a mixed fermentation device for liquid state fermentation in a laboratory and belongs to the field of wine making engineering. The problem is solved that a common liquid statefermentation device in the laboratory cannot separate two kinds of bacteria for mixed inoculation, and accordingly fermentation solutions cannot be in sufficient contact. The mixed fermentation devicefor liquid state fermentation in the laboratory comprises tanks (1) and is characterized in that each tank (1) is provided with a tank port (7) and a side port (6), the two tanks (1) are communicatedthrough the tank ports (7), the tank ports (7) are provided with outer threads, the junction is hermetically connected with a connection device (2) provided with an inner thread matched with the outer threads of the tank ports (7), and the tank ports (7) are provided with pad layers (3). According to the mixed fermentation device, by adding a right-hand thread and left-hand thread communication device, the independent pad layers with meshes formed in the centers and filter paper, it can be guaranteed that the fermentation solutions in the two glass tanks can be sufficient contact while cell separation of inoculated thalli is achieved, the problem is solved that a common device cannot guarantee thallus separation during contact of the fermentation solutions, and a proper device for scientific research is provided for research for influence of mixed inoculation fermentation on the thalli and fermentation in the laboratory.

Description

technical field [0001] The invention discloses a mixed fermentation device for laboratory liquid fermentation, which belongs to the field of brewing engineering. Background technique [0002] Mixed inoculation fermentation has received more and more attention in the brewing of various fermented wines. Different strains are inoculated simultaneously or sequentially in the liquid fermentation broth to realize different physiological and biochemical processes of fermentation and improve the flavor complexity of brewed wine. Most of the existing liquid fermentation devices in the laboratory are ordinary mixed fermentation devices, that is, the inoculated bacteria and the fermentation liquid exist in the same fermentation space, especially when the inoculation with composite strains cannot be separated under the premise of mixing the fermentation liquid Different strains. Studies have shown that when complex strains are used, different bacterial cells may kill or inhibit each ot...
