Characteristic :
1 high thermal efficiency. Because the heat transfer mechanism of roller dryer is a heat conduction, the heat transfer direction is consistent throughout the operation period. All for the evaporation of the wet parts of the tube material film, the thermal efficiency of up to 80%-90% 。
2, flexible operation, wide applicability. A lot of drying factors of the rotary drum dryer. Such as feed concentration, paint film thickness, the temperature of the heating medium, the rotation speed of the roller, can change the drying efficiency of the drum dryer, and many factors are not implicated. This will bring great convenience to the drum drying operation, so that it can adapt to the drying of various materials and different production requirements.
, the drying time is short. The drying period of materials generally only 10 to 15 seconds, it is suitable for heat sensitive materials. If the roller dryer is set in the vacuum, it can be operated under the pressure reducing conditions
4, the drying rate is large. Because the material coated on the tube wall is very thin, generally in the 0.3-1.5mm, and the heat transfer and mass transfer in the same direction, the film surface can maintain 30-70kg.H20 / m2.h evaporation.
