Problems solved by technology

Although the purpose of increasing the content of nutrient components of distiller's grains and improving the utilization rate has been achieved, it is difficult to meet the needs of large-scale and mechanized production due to the small output and long fermentation time due to the use of box-type fermentation in this method.

Abstract

The invention discloses a method for producing protein feed raw materials by carrying out enzymolysis and fermentation on white spirit vinasse. The method comprises the following steps of: culturing a candida tropicalis fermentation solution, a bacillus natto fermentation solution and a lactobacillus plantarum fermentation solution in liquid, and preparing into a mixed bacterium solution according to the ratio; filling the white spirit vinasse and CaO into an explosion cylinder according to the ratio; carrying out steam explosion under a certain condition; mixing exploded materials, the mixed bacterium solution and corn slurry at the ratio; meanwhile, adding an enzyme preparation to prepare a mixed material; and feeding the mixed material into a special modularized solid-state biological raw material continuous fermentation device to carry out enzymolysis and biological fermentation; and drying the fermented materials to obtain the protein feed raw materials. According to the method disclosed by the invention, the exploded materials, the fermented bacterium solution and the enzyme preparation are mixed and then are conveyed into the special modularized solid-state biological raw material continuous fermentation device to carry out the enzymolysis and biological fermentation, so that the requirements of automatic temperature control, humidity control and ventilation amount control are realized; the biological conversion rate is high, the fermentation period is short, the loss is less, the cost is low, and the mechanical and large-scale production can be realized.

Description

Technical field [0001] The present invention involves the use of leisurelly, especially the method of liquidase to produce protein feed raw materials. Background technique [0002] With the rapid development of my country's animal husbandry, feed raw materials are gradually scarce, prices have continued to rise, and the development and application of new feed resources has become the research direction of modern animal husbandry.The liquor is the residues of sorghum, wheat, corn, grain, etc. after fermentation, distillation and extraction of alcohol. It contains a certain amount of nutrients such as protein, amino acids and starch.For a long time, only part of the liberal grains have been directly used as rural feed or fertilizer, and most of them are abandoned as waste, causing amazing resources.Due to a large amount of crude fiber in the liquor, the nutritional structure cannot meet the requirements of scientific breeding, and the nutrients cannot be fully digested and absorbed...
