With the continued deepening of the "Zero Waste City" initiative, industry pain points such as indiscriminate dumping, easy decomposition of food waste, heavy environmental disposal pressure, and low resource utilization rates are becoming increasingly prominent. Traditional landfill and simple fermentation methods for food waste not only easily breed bacteria and produce foul-smelling leachate, but also waste a large amount of organic nutrients. Addressing this urgent industry need, our company has launched a fully automated one-stop production line solution for food waste to become animal feed. Using a specialized high-temperature dryer for food waste as the core equipment, it integrates pretreatment, sorting and impurity removal, dehydration and degreasing, high-temperature sterilization and drying, fine material preparation, and environmental deodorization throughout the entire process. This compliantly achieves the harmless disposal and resource recycling of food waste, transforming waste kitchen scraps into high-quality, high-protein organic feed raw materials, creating a closed-loop model that empowers both environmental protection and revenue generation.
The entire production line adopts a standardized closed-loop process: After the kitchen waste is collected and transported into the plant, it first passes through a fully automated unloading and screening system to precisely sort inorganic debris such as plastics, tableware, glass, and metal, preventing impurities from affecting subsequent production. Then, through crushing and pulping, solid-liquid separation, and oil-water degreasing processes, kitchen waste oil is separated and recycled, retaining high-nutrient organic solids. The core process utilizes a customized kitchen waste dryer, employing a high-temperature hot air sterilization and drying process to rapidly reduce the material's moisture content from 75%-85% to below 12%, addressing the characteristics of kitchen waste such as high moisture content, high viscosity, susceptibility to mold, and presence of pathogens. The equipment features a built-in exclusive dispersing and anti-sticking structure, completely solving the problems of kitchen waste sticking to the drum, clumping, and uneven drying. Simultaneously, sterilization, deodorization, and insect egg inactivation are completed under high-temperature conditions, ensuring the safety and compliance of the finished feed product from the source and preventing secondary transmission of pathogens.
The dried material has a loose texture and retains its nutrients intact. After fine grinding, proportioning, and pelleting, it produces high-quality organic protein feed, widely applicable to livestock and poultry farming, aquaculture, and black soldier fly larvae breeding substrates. It replaces traditional feed ingredients, significantly reducing procurement costs for livestock enterprises. The entire production line is equipped with a PLC intelligent centralized control system, automating feeding, temperature control, speed regulation, and discharging. It can operate continuously and stably 24 hours a day with minimal manual labor and low energy consumption. It also features an integrated negative pressure deodorization, wastewater treatment, and dust removal system, ensuring no odor, no wastewater discharge, and no dust pollution throughout the process. It fully complies with local environmental inspection standards and is suitable for large, medium, and small-scale kitchen waste treatment centers, environmental technology companies, breeding bases, and industrial park supporting projects.
Compared to traditional processing methods, our feed production line, centered around a dryer, offers significant advantages: integrated high-temperature drying and sterilization replaces cumbersome traditional disinfection procedures, increasing production efficiency by over 40%; materials are dried uniformly with controllable moisture content, resulting in easily stored, mold-free, and nutritionally stable finished feed; the entire solution supports modular customization, allowing for customized capacities from 1-30t/h to suit various project sizes and needs based on customer site and processing volume requirements.
We provide turnkey, one-stop service, encompassing site surveys, customized process solutions, equipment manufacturing, on-site installation and commissioning, operator training, and lifetime after-sales maintenance. Leveraging our mature drying technology and experience from hundreds of successful projects, we help customers compliantly dispose of kitchen waste, revitalize solid waste resources, and simultaneously achieve multiple revenue streams through recycled feed and waste oil recovery, seizing the opportunities presented by the solid waste resource utilization industry.
