1. Rational internal structure , high efficiency, and remarkable energy - saving . According to our inspecting result , the heat efficiency is about 85% more than traditional dryer.
2. Cylinder self- insulation thermal efficiency can reach to above 70% (traditional single cylinder dryer heat efficiency is only 35%),so it can improve thermal efficiency at least 35%.
3. Covers an area of 50% lower than single drum dryer, and civil work investment can reduce 50%, power consumption reduced by 40%. In addition, The external cylinder has higher heat preservation and heat insulation effect ,so outer tube surface temperature is near to room temperature, it will not only keeps high heat energy utilizing efficiency , but also can improve the working environment and conditions.
4. It can easily adjust the final moisture according to client’s requirement.
5. Low outlet temperature , and long service time of dust collection system to keep clean working environment.
6. New-type driving system design. It adopt of tug wheel transmission without gear transmission. Motor adopts frequency controlling motor, and the rotating speed of cylinder could be adjustable according to the moisture, production capacity.
7. Using automatic temperature monitoring and controlling system, make operation more convenient.
