Material Flow: the crushed materials of which the moisture is about 35%-55% are sent into the roller by conveyor to realize downstream 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 fastly and are discharged out of the roller. Wet materials that still don’t achieve drying effect couldn’t move fastly due to self-weight, and are dried completely during the controlling route, thus achieving drying effect. Material moisture is decreased to 12%-15%. After the whole drying process is completed, materials are discharged by screw conveyor. Inside the roller is installed with vibrating cleaning device, which prevents materials from bonding to the cylinder wall.
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 300-500℃, 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.
Straw Drying Production Line has the characteristics of high temperature resistance and can dry raw material with high temperature hot air.
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.
Adopts "centering roller device", which makes the roller and roller ring have linear contact, which greatly reduces wear and power loss.
Straw Drying Production Line has strong anti-overload capability, large processing capacity, low material consumption and low drying cost.
