According to the requirement of the market, Zhengzhou Dingli New Energy Technology Co., Ltd designs and manufactures paddle rotary dryer, which is as known as the 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 increases 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 the inner shoveling plate, materials are taking and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle and outer layer). The heat exchange is realized between material and hot air.

1. It can realize intelligent control, one-touch operation, automatic operating parameter control. The dryer stays at the best operating status all the time, thus guaranteeing that the dried material is of stable moisture and bright color.
2. The internal agitator can realize the process of mixing, dispersing and crushing, which ensures the full mass transfer and heat transfer between hot air and wet material. the unit capacity is raised to more than 50% and the energy consumption is reduced by more than 30%.
3. It adopts four-wheel driving which is more stable and reliable.
4. Saving 40% space and civil investment and 20%equipment investment compared to traditional dryers.
5. The inner structure of the dryer uses multiple efficient lifting plates combined mode, thus controlling the drying process and heat distribution effectively. High heat use ratio, the discharged off-gas temperature is lower than 50℃.
6. It controls the material flow by frequency control. Users can adjust the required final moisture index easily based on the requirement.
7. Modularized dust collecting-purifying heat recycles use allocation, safe and environmental.
8. It can be matched with a few new type hot blast stove. Efficient and energy-saving, controllable heat supply, simple operation. The energy consumption decline reaches up to 30 %, power consumption decreases by 20 %, the operating cost is lower.
