【Application】: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,
According to the demand of the market, Zhengzhou Dingli New Energy Technology Co., Ltd designs and manufactures paddle rotary dryer, which is also named a paddle-harrow rotary dryer. It is specifically designed according to the problems of the 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 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 a spiraling pattern. The agitator installed inside the 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.

It introduces novel and unique sealing device, and is matched with thermal insulation system of excellent effect, thus decreasing the coal consumption of the whole drying system.
Dryer internal structure using a variety of high-lift board combination mode, effectively regulate the drying process and heat distribution, high heat utilization, exhaust gas discharge temperature is low.
Rapid drying moisture reducing from 65-75% to 14-18% in one-time. Pasture temperature is always lower than 50 ℃, dried grass completely retained the nutrients of fresh pasture, bright color, smell fragrance.
Supporting a variety of new energy-saving clean hot air blast stove, fuel can be diesel, gas, coal, wood, wood chips, straw etc. And efficient energy, heating controllable, simple operation, energy consumption decreased by as much as 30%, power consumption reduced by 20%, the operating cost is lower.
