1.The skill content is high, outside the barrel the heat preservation inner tube effect, the heat efficiency is as high as 35%. The single cylinder dryer the thermal efficiency is only 80%, in the use of time cent more energy saving, the output value is higher.

2.Three cylinder dryer is not selection of gear drive, the conflict between the roller and the cylinder body of the conflict between the force of the machine to dry and dry machine. The stability of the dryer.

3.Three cylinder dryer outlet temperature is low,that is conducive to the end of the life of the dust system.
