Abstract

The invention relates to a movable fermentation method for preparing a wet-state yeast culture by using rice husk removed white wine vinasse as raw materials. The movable fermentation method comprises the following steps: removing rice husks from white wine vinasse, compounding materials, activating strains, performing inoculation and mixing, controlling temperature for fermentation, performing enzymolysis for breaking walls, and postprocessing products, wherein the step of postprocessing products comprises the steps of inspecting products, packaging inspected products and obtaining finished products. According to the movable fermentation method disclosed by the invention, a mechanical method is adopted for separating the rice husks, the content of crude fibers in the products is reduced, the nutrient value of the products is increased, and the application range of the products is extended. The rice husks separated from the white wine vinasse are mixed with coal to be used as boiler fuel, and a heat source is provided for warming the products, so that the cost of heating power is reduced, comprehensive utilization is realized, and the pollution is not caused. A bacteria-enzyme synergistic fermenting enzymolysis technology combining microzyme, protease and cellulose is adopted, so that the stability of the technology is good, mold pollution is not caused, and the products are safe. A temperature control technology by a two-step method is adopted, so that the cultured yeast count is high, the enzymolysis is thorough, the wall breaking of the yeast is sufficient, and the nutrient value is higher.

Description

technical field [0001] The invention relates to a method for producing a feed wet yeast culture by using rice husk-removed distiller's grains as a raw material through a collaborative process of fermentation and enzymatic hydrolysis, in particular to a method of removing the rice husks from the distiller's distiller's grains by mechanical separation, and then The method further improves the nutritional value of distiller's grain protein through the synergistic process of fermentation and enzymatic hydrolysis, which belongs to the technical field of bioengineering. Background technique [0002] Wet yeast culture is a kind of micro-ecological preparation, mainly Saccharomyces cerevisiae, which is processed under the control of modern fermentation technology by combining liquid and solid state or directly fermenting on solid medium together with solid substrate. This product does not contain a large amount of active yeast. Yeast is only a tool in the production of yeast culture...
