1. The overall size of the dryer is reduced by more than 30% compared to ordinary single-cylinder rotary dryers, thereby reducing external heat loss.
2. The thermal efficiency of the self-insulating dryer is as high as 80% (compared to only 35% for the ordinary rotary dryer), and the thermal efficiency is 45% higher.
3. Due to the compact installation, the floor space is reduced by 50%, and the infrastructure cost is reduced by 60%
4. The temperature of the finished product after drying is about 60-70 degrees, so that it does not need an additional cooler for cooling.
