Higher the temperature of  dealingmedium, faster the speed of dealing process. Large difference in temperature between  medium and raw material results the high speed of heat transfer. If dealing raw material directly with high-temperature flue gas, better effect will be acquired. Thus, if necessary, we should use the flue gas as often as possible. Lower the relative humidity of dealing medium, faster the gasification of water content and dealing speed. If we use the flue gas as drying medium, its humidity is related with the air humidity, water and hydrogen content in fuel.

Bigger the contact surface between dealing medium and raw material, faster the drying speed. Thus during the dealing  process, we can break raw material into pieces or make raw material in suspension state. Also, we can install the lifting board or grating in the sawdust rotary dryer so as to widen the contact area between dealing medium and raw material, improve the drying speed and shorten dealing time.

During the actual working process of Sawdust Pellet Machine, if the drying speed is slow, the total output will decrease a lot. The point to improve the dealing efficiency and output of sawdust pellet machine has been focused all the time. Thus the above points are very helpful.
