What is Food Waste Drying Production Line?
Food waste (catering garbage) is the largest urban organic solid waste, produced in large quantities from restaurants, canteens and food processing factories. Fresh food waste has ultra-high moisture of 80%-90%, mixed with residual oil, starch, vegetables and meat residues. Without professional treatment, it will rapidly rot, breed bacteria, emit foul odor, and cause serious environmental pollution and ecological damage.
Traditional food waste treatment methods such as direct burial and incineration cause secondary pollution and resource waste. Ordinary drying equipment cannot adapt to oil-water mixed viscous food waste, easily causing wall sticking, mold growth, incomplete sterilization and serious odor overflow. Our dedicated Food Waste Drying Production Line integrates sorting, crushing, deoiling, sterilization, deodorization and drying, solving multiple industry pain points in one set of equipment. The treated dry materials can be reused for organic fertilizer, biomass fuel and soil improvement, realizing green circular economy and compliant environmental protection discharge.

Working Principle & Production Process of Food Waste Drying Production Line
Working Principle
The Food Waste Drying Production Line adopts integrated pretreatment + gradient low-temperature drying + high-temperature sterilization and deodorization technology, specially designed for high-oil, high-moisture and perishable food waste. After professional sorting and crushing pretreatment, the bulk and agglomerated food waste is turned into uniform fine materials, removing floating oil and sundries in advance to reduce material viscosity.
The pretreated materials enter the anti-corrosion drying drum stably. Through three-stage gradient temperature control drying, the materials complete surface dehumidification, deep dehydration and cooling shaping in turn. The high-temperature sterilization module kills harmful bacteria in real time, and the tail gas purification system decomposes odor molecules. Combined with waste heat recovery circulation technology, it realizes efficient, energy-saving and harmless drying treatment of food waste, and finally outputs dry, sterile and odorless recyclable materials.
