Abstract
The invention relates to a fermentation method for making alcohol-fixed yeast fluid bed from sweet kaoliang stem, and pertains to the technical field of fermentation for biologic mass. The method comprises preparing saccharomycetes fluid, preparing sodium alginate solution, preparing calcium chloride solution; mixing the sodium alginate solution with the calcium chloride solution, preparing and solidifying the fixed yeast particles, making particles by a particle maker; carrying out centrifugal movement by a centrifugal disc of the particle maker by taking use of the mixture of the yeast and the vector sodium alginate; the mixture breaks into drips when the tension is less than the centrifugal force, and falls into the calcium chloride solution in the particle tray of the particle maker to solidify and becomes particles. The invention is of short fermentation period, high transformation efficiency, and obvious effect in increasing output and reducing consumption. The fixing yeast during the fermentation will not lose and can be used in a repeated way.
Description
Technical field
The present invention relates to the immobilized yeast fluid-bed fermentation technique of preparation of ethanol by sweet Chinese sorghum stalk, belong to the biomass ferment technical field.
Background technology
In the existing sweet sorghum stalk process for preparing ethanol by fermentation, still adopt the method for traditional batch fermented yeast bacterial classification.The batch fermentation barms can not use repeatedly, production cost height, production efficiency are low, and labour intensity is big, and energy consumption is big, unstable product quality etc.
Summary of the invention
For addressing the deficiencies of the prior art and weak point, the invention provides a kind of realization alcoholic acid and continuously ferment fast, reduce production costs, enhance productivity, reduce labour intensity, energy consumption is low, the preparation of ethanol by sweet Chinese sorghum stalk immobilized yeast fluid-bed fermentation method of constant product quality.
The preparation of ethanol by sweet Chinese sorghum stalk immobilized yeast fluid-bed fermentation method comprises the preparation of yeast liquid, it is characterized in that further comprising the steps of: the preparation of sodium alginate soln; The preparation of calcium chloride solution; The producing, solidify of the mixing of sodium alginate and yeast liquid and immobilized yeast particle; granulation process adopts tablets press to finish: the mixture that utilizes yeast and carrier sodium alginate; centrifugal pan by tablets press is made centrifugal motion; when its tension force during less than centrifugal force and fragment into droplet; fall into the particle pallet calcium chloride solution solidifying formation of tablets press, realize granulation.
This technology is to adopt advanced immobilized yeast technology to transform traditional ethanol fermentation technology, and fermentation period is short, efficiency of conversion is high, volume increase consumption reduction effect is obvious, is a major technological breakthrough of ethanol fermentation industry.It is compared with traditional zymotic technology, has following characteristics: fixed yeast does not run off and can use repeatedly during the fermentation, and the usage period, anti-assorted bacterium ability was strong, is difficult for microbiological contamination at 150～180 days; No longer need distiller's yeast to cultivate; Fermentation time shortens to 8～10 hours; Significantly improved the throughput of fermentation equipment; It is the alcohol production enterprise of raw material that this technology is equally applicable to starch material and molasses.
Embodiment:
The immobilized yeast fluid-bed fermentation technique of preparation of ethanol by sweet Chinese sorghum stalk comprises the preparation of yeast liquid, the preparation of sodium alginate soln; The preparation of calcium chloride solution; The producing, solidify of the mixing of sodium alginate and yeast liquid and immobilized yeast particle; granulation process adopts tablets press to finish: the mixture that utilizes yeast and carrier sodium alginate; centrifugal pan by tablets press is made centrifugal motion; when its tension force during less than centrifugal force and fragment into droplet; fall into the particle pallet calcium chloride solution solidifying formation of tablets press, realize granulation.
