Sugar beet pulp dryer, which is also named impeller mixing rotary drum drier, rake roller dryer, rotary rake drum dryer, rotary paddle roller dryer. It is specifically designed according to the problems of traditional rotary dryer which is not suitable for high-moisture materials that MC is higher than 50% and the viscosity is relatively low. Meanwhile since the ‘black hole’ phenomenon occurring in the drum lowers the drying capacity and raises the energy consumption, the paddle rotary dryer sets high-speed spinning paddles, strengthening the crushing and separating function. The crushing effect enlarges the contact surface of particles, which largely increase the heat transfer rate and vaporization rate. According to the practical test, the unit vaporization capacity per hour of paddle rotary dryer is as much as 25-60kg/m2, which is 1-2 times of traditional rotary dryer. The output is raised by 50% and fuel consumption is reduced by 30%. At the same time, the footprint and drying efficiency is raised by 40%. It is applicable for the drying process of high-moisture materials with 50%-85% moisture, such as sugar beet pulp, sludge, bean dregs, starch residue and sauce residue, spray corn bran, cassava dregs, brewer's grains, distiller's grains, straw, grass, organic fertilizer, chicken beef feces . We also help optimize the drying process according to the property of different biomass materials, production scale, application requirements, cost control, automation level and site condition.
Material Flow: the raw material with 80-85% 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. 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 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
Sugar Beet Pulp Dryer has the characteristics of high temperature resistance and can dry raw material with high temperature hot air.
Low consumption and low cost
Sugar Beet Pulp Dryer 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.
