Paddle Rotary Drying Plant

Product Introduction

Zhengzhou TongDing machinery Co., Ltd has responded to market demand by designing and manufacturing a paddle rotary dryer, also known as a paddle-harrow rotary dryer. This dryer was specifically created to address issues with traditional rotary dryers, which are unsuitable for materials with high moisture content exceeding 50% and low viscosity. Additionally, the "black hole" phenomenon present in traditional rotary dryers reduces drying capacity and increases energy consumption. To combat these problems, the paddle rotary dryer is equipped with high-speed spinning paddles that enhance crushing and separating functions. This crushing effect expands particle contact surface area, greatly increasing heat transfer and vaporization rates. Practical tests have shown that the unit vaporization capacity per hour of the paddle rotary dryer can reach 25-60kg/m2, twice that of traditional rotary dryers. This leads to a 50% increase in output and a 30% reduction in fuel consumption. Furthermore, the paddle rotary dryer improves drying efficiency by 40% and occupies a smaller footprint. It is suitable for drying high-moisture materials with 50%-65% moisture content, 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 provide assistance with optimizing the drying process based on the properties of different biomass materials, production scale, application requirements, cost control, automation level, and site conditions.

Working Principle

Zhengzhou TongDing machinery Co., Ltd has responded to market demand by designing and manufacturing a paddle-harrow rotary dryer, also known as a paddle rotary dryer. This dryer addresses the limitations of traditional rotary dryers, which are not suitable for high-moisture materials with moisture content exceeding 50% and low viscosity. Furthermore, the "black hole" phenomenon that occurs in the drum of traditional rotary dryers reduces drying capacity and increases energy consumption.

To mitigate these issues, the paddle rotary dryer employs high-speed spinning paddles, which enhance the crushing and separating function of the dryer. The crushing effect enlarges the contact surface area of particles, leading to increased heat transfer and vaporization rates. Practical tests have shown that the unit vaporization capacity per hour of the paddle rotary dryer is as high as 25-60kg/m2, twice that of traditional rotary dryers. As a result, output is increased by 50% and fuel consumption is reduced by 30%. Additionally, the footprint and drying efficiency of the paddle rotary dryer are raised by 40%.

This dryer is suitable for drying high-moisture materials with 50%-65% moisture, including 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 stalks, and peanut vines. We also offer assistance in optimizing the drying process to suit different biomass materials' properties, production scales, application requirements, cost control, automation levels, and site conditions.
