NOVELTY - Converting kitchen waste and animal and vegetable wastes to yeast protein feed, comprises (i) pre-processing raw materials by crushing, separating oil, and then crushing by placing the raw materials into a stirrer; (ii) sterilizing; (iii) performing enzymatic hydrolysis by adding neutral protease, amylase and saccharifying enzyme; (v) performing solid-liquid separation process; (vi) fermenting; (vii) inoculating strain into solid and liquid culture medium placed in fermentation tank; and (viii) carrying out aerobic fermentation or anaerobic fermentation, crushing, and packaging.    USE - The method is useful for converting kitchen waste and animal and vegetable wastes to yeast protein feed (claimed).    ADVANTAGE - The method has rapid effect; performs low cost integrated processing of raw materials; is simple, suitable for industrial production line of automatic production process, and environmental friendly; and saves energy.    DETAILED DESCRIPTION - Converting kitchen waste and animal and vegetable wastes to yeast protein feed, comprises (i) choosing raw material, collecting, and pre-processing the raw materials by classifying, crushing, separating oil which is utilized for industrial purpose or in the production of biodiesel, and then crushing by placing the raw materials into a stirrer; (ii) sterilizing by adding chlorine dioxide or sodium hypochlorite used as sterilizing liquid into pre-processed raw materials, and simultaneously eliminating bad odor, removing toxic- and harmful- components e.g. aflatoxins, hydrogen sulfide, cyanide, pesticide residues, veterinary drug residues and other toxic substances; (iii) removing disinfectants from sterilized raw materials by adding vitamin C as a reducing agent, uniformly stirring, and completely removing residual chlorine dioxide or sodium chlorite; (iv) adjusting pH to 6-7, maintaining temperature to 25-50 degrees C, adjusting water content, then adding neutral protease, amylase and saccharifying enzyme, and completely stirring while carrying out enzymatic hydrolysis for 1-10 hours, decomposing proteins and starch, and completely mixing by adding keratin proteins containing raw materials e.g. feathers and fish scales, and carrying out enzymatic hydrolysis for 1-10 hours; (v) subjecting the enzymatically hydrolyzed product to solid-liquid separation process by adding into a solid-liquid separation machine, and adding solid material into a solid fermentation machine, and liquid material into a liquid mixer, separating the precipitate, filtering, placing the filtrate into a liquid fermentation tank, and processing the harmless residues; (vi) adjusting the pH of solid and liquid materials to 5-6, and fermenting by adding into a fermentation tank, and adjusting the temperature to 25-35 degrees C, and adjusting the moisture content of solid culture medium in the fermentation tank to 55-60%; (vii) inoculating strain into solid and liquid culture medium placed in fermentation tank, adding 1% calcium hydrophosphate, adding urea into the medium having nitrogen dry substance content of 1.5% or less, and simultaneously adding phytase, completely-uniformly stirring, maintaining the solid-liquid culture medium temperature at 25-35 degrees C, where the air humidity conditions in the solid state fermentation tank is maintained at 90-95% before carrying out the fermentation stage, and promoting rapid growth of mycelium on the culture medium surface, and maintaining air humidity conditions in the solid state fermentation tank at 70-80%, and allowing the growth of mycelium by pushing inside the culture medium; and (viii) carrying out aerobic fermentation for 1-2 days or anaerobic fermentation for 6-7 days, once the fermentation process is completed, and concentrating the liquid fermentation broth by spray-drying, and subjecting the solid fermentation broth to solid fermentation under vacuum drying conditions or drying, crushing, and packaging, to obtain the product.
