Embodiment 1

[0050] 1600kg of husk-removed distiller's grains, 100kg of bran, 100kg of soybean meal, brewing active dry yeast (the specification is 2×10 10 pcs / g) 1kg, add 10kg of warm water containing 1% sucrose to activate for 30 minutes, protease (50000u / g) 0.2kg, cellulase (50000u / g) 0.2kg, molasses 20k, mix well, add The pool is controlled at a temperature of 32°C for 36 hours of fermentation. After turning over the materials, the accumulation is continued and the temperature is raised. The temperature is controlled at 50°C for 12 hours of enzymatic hydrolysis, granulation, drying, and packaging is the product.

Embodiment 2

[0052] 1500kg of husk-removed distiller's grains, 100kg of bran, 150kg of soybean meal, brewing active dry yeast (the specification is 2×10 10 pcs / g) 1.2kg, add 12kg of warm water containing 1% sucrose to activate for 30 minutes, protease (50000u / g) 0.3kg, cellulase (50000u / g) 0.2kg, molasses 30k, mix well, Enter the pool to control the temperature at 30°C and ferment for 24 hours. After turning over the material, continue to pile up and heat up. Control the temperature at 45°C for 36 hours of enzymatic hydrolysis, granulate, dry, and pack to become the product.

Embodiment 3

[0054] 1800kg of husk-removed distiller's grains, 50kg of bran, 50kg of soybean meal, brewing active dry yeast (the specification is the number of effective viable bacteria 2×10 10 pcs / g) 2kg, add 20kg of warm water containing 1% sucrose to activate for 30 minutes, protease (50000u / g) 0.1kg, cellulase (50000u / g) 0.1kg, molasses 40k, mix well, add The pool is controlled at a temperature of 35°C for 36 hours of fermentation. After turning over the material, it continues to pile up and heat up. The temperature is controlled at 50°C for 12 hours of enzymatic hydrolysis, granulation, drying, and packaging to become the product.

Abstract

An extrusion granulation fermentation process of a yeast culture by taking distillers grains without rice husks as raw materials comprises the steps of rice husk removing treatment of the distillers grains, batching, strain activating, inoculate mixing, temperature controlled fermentation, enzymolysis wall-braking, granulation, drying and product aftertreatment which comprises inspection, packaging and finished product obtaining. According to the extrusion granulation fermentation process of the yeast culture by taking the distillers grains without the rice husks as the raw materials, effective separation of rice husk compositions from nutritional ingredients such as protein in original distillers grains is achieved by adopting a screw extrusion machine, the cellulose content of products is reduced, and the nutritional value is improved. The rice husks separated from the distillers grains can be mixed with coal to be used as boiler fuel to provide the heat source for the products, the heat cost is reduced, comprehensive utilization is achieved, a bacterium-enzyme cooperative fermentation enzymolysis process by combining yeast and protease and cellulase is adopted, the process stability is good, fungus pollution does not exist, and the products are safe.

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] Yeast culture is a kind of microecological 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 pro...
