The food waste drying production line purchased by Shaanxi customers from our company has been successfully put into operation. The system adopts a complete set of equipment, including feeding, sorting, solid-liquid separation, crushing, oil-water separation, solid fermentation, drying and sterilization, odor collection and purification system, PLC automatic control system and other processing units. By processing, the resources are recycled and the food waste is turned into treasure. It solves the environmental pollution caused by the urban catering group randomly discarding the food waste and not using it.
