Cassava residues (potato residues, sweet potato residues, potato residues, etc.) are by-products of manufacturers such as starch factories and alcohol plants. Potato residues are rich in cellulose, hemicellulose and crude protein. The material has complete amino acid components, and the crude protein content in the bacterial protein is as high as 40%-50%, which has the effect of accelerating the growth of livestock and poultry. This equipment can dry the potato residue for storage or use as feed. Zhengzhou Dingli’s special potato residue dryer is developed for the characteristics of sweet potato residue, cassava, and potato residue raw materials, and after multiple sets of dryer production practices, it can dry all kinds of potato residue to less than 12% at one time.
Material flow: 75-85% moisture content material first with special dehydration machine removing a part of moisture, the moisture removed around 68%, then send into the dryer by screw conveyor to realize downstream drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Inside mixing blade device will be fully stirred and crushed material, material and hot air through full heat exchange, the rapid evaporation of water vaporization, reaching about 35%, discharged by the screw conveyor, then send into the semi-wet material crusher, crushed material size below 1mm, then into pulse air drying process, within 10-15s the material quickly removed to 10% by the cyclone discharger and Pulse bag dust collector recovery dry powder, exhaust emissions amount to the national standard requirement, to complete the entire drying process. The drum cleaning device is installed inside the drum to prevent the material from adhering to the cylinder wall.
