Method for processing granular pig feed by employing swill

Abstract

The invention provides a method for processing a granular pig feed by employing swill. The method comprises the following steps: 1 fully mixing processed paste swill with wet bean dregs and cavings fully, so as to form a primary mixture, wherein the paste swill accounts for 50% of the primary mixture, the wet bean dregs account for 30% and the cavings account for 20%; drying the primary mixture, so as to reduce the humidity to 50%; 2, adding corn grits, bran and wheat middling to the primary mixture with the humidity being 50%, stirring and mixing to obtain a secondary mixture, wherein the primary mixture with the humidity being 50% accounts for 76% of the secondary mixture, the corn grits account for 11%, the bran accounts for 7%, and wheat middling accounts for 3%; and 3 producing the granular feed through a granule compressor when the humidity of the secondary mixture is reduced to 20-25%, and drying the granular feed until the humidity is 10%-15%, so as to form the product. According to the method, the paste swill, the wet bean dregs and the cavings are mixed; the wet bean dregs have coagulating power; the nutritional ingredients of the swill are absorbed and softened by the cavings; and absorption and digestion of animals are facilitated.

Description

technical field [0001] The invention relates to the field of pig feed processing, in particular to a method for processing granular pig feed with swill. Background technique [0002] With the concentration of the population, the swill is also concentrated, and the current main use is feed. [0003] my country's feed industry equipment and process technology have reached the level of developed countries, and the treatment and processing of swill is already a mature advanced technology. [0004] The treatment of swill mainly involves two major processes. One is to clean up the impurities in the swill before the swill treatment. Minerals such as fishbone and fishbone and meat waste can be fully utilized after being crushed by a crusher. [0005] The second is high-temperature sterilization. The high-temperature gas generated by the boiler can be used to perform high-temperature disinfection and sterilization along the water. Generally speaking, high-temperature gas above 100°...
