This system smashes material firstly, which is convenient for subsequent dehydration. After dehydration, it dries the dehydration materials, which decreases the drying heat consumption. In addition, during the high-temperature drying process, it inactivates the harmful microbe inside the material. Setting up individual sterilization technology is not required, which simplifies the material processing process, saves the energy required in individual sterilization.

Three main paths for the comprehensive utilization of food waste

1. Make the kitchen waste as protein feed. The food waste through sorted, impurities are removed, crushed, dehydrated, deoiled, and oil recovered, biomass diesel is produced, and yeast, probiotics, and auxiliary materials are added. After aerobic fermentation, drying, cooling, packaging, wastewater, and waste gas pass through to meet the discharge standards, the final product is protein feed and biomass diesel.

2. Process kitchen waste as organic fertilizer. Food waste is sorted, impurities are removed, and crushed, dehydrated, deoiled, oil is recovered. To produce the biomass diesel, it needs to add yeast, enzyme preparations, and auxiliary materials. After aerobic fermentation, drying, cooling, packaging, wastewater, and waste gas process to reach the discharge standards, the final product is an organic fertilizer and biomass diesel. 

3. Use kitchen waste to product biogas. After the sorting of kitchen garbage, impurities removed, crushed, deoiled, and oil recovered and adds anaerobic bacteria. In the sealed tanks, anaerobic fermentation is used to produce biogas for power generation or combustion, and waste residues are dehydrated, drying, cooling, and packaged, and the wastewater is treated and discharged up to standard. The final products are biogas, organic fertilizer, and biomass diesel.
