Food waste can be made into pellet 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 pellet feed are to realize disinfection and sterilization, meet feed hygiene standards, 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 dried to produce proteins. The physical method is to dehydrate, dry, and disinfect the food residue directly, and then grind it into feed.
 
The treatment process for making food waste into 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 is made after high-temperature sterilization. The principle is to use the principle of high-temperature disinfection to kill the virus and grind it into livestock and poultry feed. A more mature way to treat food waste is to use a comprehensive set of granulation technology, extrusion drying technology, and other methods. The bacterial concentration in extruded feed was much lower than that in other samples.
 
How can food waste be made into the animal feed?
 
After years of efforts, our company has adopted 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 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. The food waste is crushed and pressed, and 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, special bacteria are added, and the pre-set operating parameters, The equipment can operate automatically for 24 hours. After 24-hour continuous treatment, 90% of food waste is metabolized into steam and bioenergy, and 10% of organic fertilizer is discharged.
