High-humidity material drying expert Zhengzhou Dingli Company develops a three-layer single-channel dryer for birth materials according to market demand, which is suitable for beer grains, white distiller's grains, wood chips, sawdust, bamboo chips, wooden shavings, shavings, barley straw, Drying of 35-65% of water such as oat straw, wheat straw, rye straw, straw, sorghum straw, corn stover, potato vine, bean stem drying, peanut vine. The drying process technology is optimized according to the characteristics of each biomass material, the size of the production, the application requirements, the cost control, the degree of automation, and the on-site working conditions. Recommended products: three-layer single-channel rotary drum dryer (patent number: ZL200920089749.2), the equipment has large output, high efficiency and energy saving, small footprint, 30-50% energy saving than ordinary dryer, which can maximize savings energy and drying costs.
The material flow is: about 35-65% of water, the material enters the inner layer of the rotary drum from the feeding device, and realizes downstream drying. The material is continuously copied and scattered under the inner layer of the copy board to realize heat exchange, material Move to the other end of the inner layer and enter the middle layer for counter-current drying. The material is continuously raised in the middle layer and is in a two-step step backward. The material in the middle layer fully absorbs the heat emitted by the inner roller and absorbs it. The heat of the middle roller, while prolonging the drying time, allows the material to reach optimum drying conditions. The material goes to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-loop manner in the outer drum. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not reach the drying effect cannot be fast due to its own weight. As the material travels, the material is sufficiently dried in the rectangular copy board to complete the drying process and is discharged by the screw conveyor. A shock cleaning device is installed inside the drum to prevent the material from adhering to the cylinder wall.
The gas flow is: the air is pressurized by the hot air blower into the hot air furnace for combustion and the temperature reaches 550-600 ° C. After being blown by the dryer, the induced draft fan sucks the dryer to dry the material, evaporates the water, and passes through the three-layer heat exchange and the air temperature. The temperature is lowered to 55-60 ° C to discharge the dryer, and the dusty moisture is collected by a cyclone dust collector and cleaned by a wet dust collector.
