1. High thermal efficiency. The principle of heat transfer of rotary drieris heat conduction which heat conducting direction keeps identical withoperation cycle. Except cap heat dissipation and radiation loss, all heat energycan be used for evaporating wet materials on the wall of roller. Thermalefficiency could reach 80%-90%.
2. Large operation elasticity and wide application. Various drying factorsof the rotary drier can be adjusted, such as density of feeding materials,thickness of materials film, temperature of heating medium, rotating speed ofroller etc, which can change drying speed. As these factors have nointerrelations with each other, it brings great convenient to dry operation,and makes it applicable to suit various materials and to meet differentrequirement of production.
3. Short drying period. The drying period of material is normally 10 to 15seconds, so it is suitable for heat-sensitive material. It can be also workingunder less pressure condition if it is put in vacuum device.
4. Drying rate is quick. As material film coated on the wall of roller isvery thin. Normally thickness is 0.3-1.5 mm, plus heat and mass transferdirection are identical, the evaporation capacity on the surface of film cankeep at 15-70kg.H2O/m2.h.
