How to Make Food Waste into Animal Feed?
Food waste can be made into animal feed through biological treatment. The biological treatment process independently developed by our company can reach the harmless discharge standard after treatment.
The basic requirements for making food waste into animal feed are to realize disinfection and sterilization, meet the feed hygiene standard, retain nutrition to the greatest extent, improve the feed value of food waste and eliminate or reduce the impact of adverse factors. At present, the domestic food waste feed recycling technology is mainly a biological and physical method. Biological methods use microbial cells to ferment food waste, and use microbial growth, regeneration and metabolism to accumulate useful cells, enzymes and intermediates that are dried to produce proteins. The physical method is to directly dehydrate, dry and disinfect the food residue, and then grind it into feed.
Treatment of Food Waste into Animal Feed:
1. biological treatment of feed preparation. The principle is to add cultivated strains to kitchen waste and store them in sealed containers. Strains grow and kill pathogens as feed.
2. feed made after high-temperature sterilization. Its principle is to kill the virus and grind it into animal feed by using the principle of high-temperature disinfection. A more mature way to treat food waste is to use a comprehensive set of granulation technology, extrusion drying technology and other methods. The concentration of bacteria in extruded feed was much lower than that in other samples.
How to make food waste into animal feed?
After years of efforts, our company has carried out system optimization, impurity separation / removal, temperature control homogenization, coagulation separation, solid-liquid / oil-water separation, microbial fermentation, indirect drying and three kinds of waste treatment. We have developed our own process technology and independently developed an equipment suitable for large-scale treatment of kitchen residues to produce composite biological protein raw materials. The sorting system is mechanized, which is more than 8 times faster than manual sorting, and the labor intensity is reduced by more than 80%.
The food waste is poured into the pretreatment system of the food waste treatment equipment by the food waste bucket elevator. After the food waste is crushed and pressed, the water content of the food waste is controlled at about 50%. Then the materials are automatically put into the local resource treatment equipment of the food waste. After the materials are added, a special bacterial agent is added. The equipment can operate automatically for 24 hours according to the preset operating parameters. After 24-hour continuous treatment, 90% of the food waste is metabolized into steam and bio heat energy, and 10% of the animal feed is discharged.
