The straw dryer is applied for drying barley straw, oat straw, wheat straw, rye straw, straw, sorghum straw, corn straw, potato vines, beanstalks ( including materials like soybean straw, broad bean straw, pea straw, cowpea straw, lupine straw, peanut vine, etc.). According to the characteristic, production capacity, applying requirement, cost control, operating convenience of each biomass material, our company optimizes the drying technology. Recommended products: three-layer rotary drum dryer, patent number: ZL2009 2 0089749.2.
This equipment is of a huge production, high efficiency, and energy-saving, small floor space. Compared with common dryer machines, it saves energy by 30%-50%, thus saving energy and drying cost to the maximum.
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.
