Problems solved by technology

[0002] Every year, the national food waste production is about 40 million tons, but its resource recycling rate is only 20%, resulting in a large waste of resources
At present, the types of food waste recycling products are relatively single, and the utilization rate of food waste is not high, causing secondary pollution
Using food waste to produce feed is a relatively common treatment technology, but food waste contains a large number of highly infectious and pathogenic microorganisms. Improper treatment will not only accelerate feed decay and oxidation, but also easily cause animal diseases and diseases. die
[0003] The patent application number is CN201310437655.0. Although the ethanol-producing residue is used to ferment again to prepare lactic acid, which improves the utilization rate and added value of food waste to a certain extent, the lactic acid-producing residue is not reused. Therefore, no Can maximize the use of food waste
The patent with the application number CN201510026227.8 reduces the number of harmful microorganisms through high-temperature treatment of kitchen waste, but it cannot kill pathogens and thermophilic microorganisms with spore structure, which still has a large safety problem. In addition, the method produces The feed has low antioxidant capacity, is perishable, and is difficult to store

Abstract

The invention discloses a method for producing ethanol, soap and a feed from kitchen waste. The method comprises the following steps of step I, performing filtration; step II, performing crushing, andperforming saccharification; step III, performing fermentation, performing distillation, and performing rectification so as to obtain ethanol; step IV, performing refinement, performing decolorationand performing saponification; step V, adding methyl ethyl ketone peroxide and associative polyurethane to reach a precipitation and solidification state, so that soap is prepared; and step VI, mixinga feed additive with vinasse, and performing sterilization through ultraviolet radiation so as to obtain a feed, wherein the feed additive consists of tea polyphenols, berberine sulfate, jasminoidin,santoquin, butylated hydroxyanisole and citric acid. Through adoption of the method disclosed by the invention, the resource utilization rate of the kitchen waste is maximized, the produced ethanol can be used as fuel and an organic solvent, the produced soap has favorable functions of cleaning, emulsifying and sterilizing, the produced feed is high in safety, high in antioxidant ability and notliable to corrupt, the irritability resistance and the immune competence of animals are strengthened, and the yield is increased.
