Dingli Brand three layer single channel food residue rotary drum dryer(patent number:ZL2009 2 0089749.2). The equipment has the advantages of large production, high efficiency, energy saving and small floor area. It can used together with the clean hot air furnace and suitable for drying high moisture materials such as food residue and so on. The moisture can be dried quickly from 65-75% to 14-18% at a time, and the dry food residue completely retains its original nutritional components, with bright colors and delicate scent. Comparing with the traditional dryer, the energy consumption can be reduced 30-50%, which can save energy and reduce the operating cost.
The dryer is suitable for food residue, oat straw, wheat straw, rye straw, straw, sorghum straw, corn straw, potato vines, bean stalks,etc. Dingli company optimizes the drying technology and equipment selection and configuration service according to the characteristics of each material, the size of production, the quality requirements, the application demand, the cost control, the automatic degree, the field working condition, the investment quota and so on.
Material Flow: the raw material with 75-85% moisture will be sent into the dewatering machine, and then the moisture will be reduced to 60-65%, then feed into the dryer by screw conveyor, concurrent flow drying. Under the effect of inner shoveling plate, materials are took and scattered constantly, and move in spiral forward method. Through three layers (inner, middle and outer layer), heat exchange are realized between material and hot air medium. The materials that achieve drying effect move forward fast and are discharged out of the roller. Wet materials that still don’t achieve drying effect couldn’t move fast due to self-weight, and are dried completely during the controlling route, thus achieving drying effect. . After the whole drying process is completed, materials are discharged by screw conveyor. The final moisture will be reduced to 14-18% (can be adjusted according to buyer’s requirement). there is special device inside the dryer, can prevent the unequal drying of materials.
Air Flow: through hot blast stove and air blower inflating, the air enters into the hot blast stove for combustion heating. Its temperature reaches up to 600-850℃, then it is inhaled by the dryer induced draft fan to dry material and evaporate water. When temperature decreases to 55-60℃, it is discharged out of the dryer. Wet air containing dust are discharged on standard through dust remover purifying.

Fast drying and high efficiency
Food Residue Drying Production Line has the characteristics of high temperature resistance and can dry raw material with high temperature hot air.
Low consumption and low cost
Food Residue Drying Production Line has strong anti-overload capability, large processing capacity, low material consumption and low drying cost.
Low wear and long life
adopts "centering roller device", which makes the roller and roller ring have linear contact, which greatly reduces wear and power loss.
Low load, no block
new feeding and discharging device, which eliminates the blockage, discontinuity, unevenness and returning of rotary drum dryer, and reduces the load of the dust removal system.
