Problems solved by technology

Although its fermentation rate is faster than that of traditional alcoholic fermentation, its shortcoming is that the immobilized yeast particles are fixed in a sieve particle basket in the fermenter, and the immobilized yeast particles do not move with the fermentation liquid, so that The dispersion of the particles is poor, the mass transfer rate between the fermentation liq

Embodiment Construction

[0023] Such as figure 1As shown, the present invention includes: an air purification system 1, a fermentation liquid feeding system 2, an immobilized yeast fluidized bed fermentation reactor system 3, a carbon dioxide circulation system 4 and a fermentation mash collection system 5. The air purification system 1 is connected to the lower part of the immobilized yeast fluidized bed reactor system 3 with a rubber tube or a metal tube, and the sterile air obtained through the air purification system 1 is blown in from the bottom of the immobilized yeast fluidized bed fermentation reactor system 3 , to provide fluidization power for the multiplication process of immobilized yeast before fermentation, and at the same time provide an aerobic environment for the multiplication of yeast; the fermentation liquid feeding system 2 is connected to the immobilized yeast fluidized bed reactor system 3 through rubber tubes or metal tubes In the middle part, the prepared aseptic fermentation ...

Abstract

The fixing barm alcohol fermentation bio-system comprises: an air cleaning system, an adding system for fermented liquid, a fixing barm fluid bed fermentation reactor, a CO2 cycle system, and a collecting system for mash; all connected in turn with rubber pipe or metal pipe to connect out from last system top and connect in the next system bottom. This invention is simple, can improves material utility with low consumption and land area.

Description

technical field [0001] The invention relates to a system in the technical field of bioengineering, in particular to an immobilized yeast bioalcohol fermentation system. Background technique [0002] In the process of producing alcohol by biological fermentation, fermentation rate, fermentation efficiency, resource utilization rate and automation level are several important indicators to measure the advanced nature of alcohol fermentation system. Therefore, a relatively advanced alcohol fermentation system should have the characteristics of fast fermentation rate, high fermentation efficiency, high resource utilization rate, high automation level, and low energy consumption. At present, my country's alcohol production industry generally uses solid-state alcohol fermentation systems and free cell alcohol fermentation systems. For the solid-state alcohol fermentation system, there are two main problems, that is, on the one hand, the fermentation reaction rate is slow and the f...
