According to the requirement of market, Zhengzhou Dingli New Energy Technology Co.,Ltd designs and manufactures paddle rotary dryer. Which is as know as paddle-harrow rotary 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 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 crushed materials of which the moisture is about 50%-85% are sent into the roller conveyor to realize downstream drying. Under the effect of inner shoveling plate, materials are taking and scattered constantly, and move in spiral forward method. Through three layers (inner, middle and outer layer). The heat exchange is realized between material and hot air.
Automatic control, to ensure the drying of sawdust water even and stable.Automatic stone removing and iron removal can ensure that the impurities of the sawdust are not in the rear process.The required investment of equipment is 1/6 of imported products.
Compared with the single cylinder drier, the utility model reduces the occupation cost by about 50%, reduces the civil investment by about 50%, A variety of material combinations Zhou Xiangyang distribution, effectively control the drying time.
Cylinder self insulation, thermal efficiency of more than 70%, With tail drive, the transmission is more stable and reliable; completely change the wheel rotation, often slip shadow, Sound production phenomenon.
Frequency control is adopted to control material flow, and the final water can be easily controlled according to the needs of users Sub index. The air outlet temperature is low, and the dedusting equipment can be used for a long time.
