According to the demand of market, Zhengzhou Dingli New Energy Technology Co.,Ltd designs and manufactures paddle rotary dryer, which is also named 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 twice 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%-65% moisture, such as wood chips, sawdust, bamboo chips, wood shavings, barley straw, oat straw, wheat straw, rye straw, rice straw, sorghum straw, corn stalks, corn bran, potato vines, beans stalk and peanut vine. 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.


Wet materials (50% - 65% moisture) are delivered to the drum for concurrent drying process through screw conveyor. Wet materials are lifted up and down by the internal flights and pushed through three layers in spiraling pattern. The agitator installed inside drum can completely shatter and blend wet materials, which realizes full heat exchange between cool materials and heated air. The dry materials could pass through the drum quickly under the air force.

1. Smart control & One-step operation. The operation parameters is under automatic control to ensure the best running condition and moisture stability of dry materials.
2. Impurities self-removal. Iron dust and other impurities are cleaned and would not enter the following process.
3. The insulation effect of drum is as high as 70% (35% for traditional product), raising the heat efficiency by 30%.
4.Four-wheel drive brings. Stable and reliable.
5. Save 50% space and civil investment compared to traditional dryers.
6. Innovative flights design. Efficient flights combination would bring better process control , thermal distribution, and heat efficiency. The temperature of exhaust gas is lower than 50℃.
7. Convenient variable frequency-control systems. Customers could change the material flow rate and product moisture based on their needs.
8. Environmental and safe. Modular configuration of dust collection and purification systems .
9. More choice for innovative air furnace with high efficiency, convenient manipulation and energy control, which could reduce 30% energy cost and 20% electric cost.
