Sawdust Flash Dryer

Sawdust Dryer is suitable for drying materials of moisture 20~50%. The rotary dryer is equipped with one fuel boilers, inlet, steel pipe, exhaust blower (fan), air lock and cyclone. Wet materials are put into the hopper. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air is flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock. This wood dryer reduces the moisture to 8~12% with the advantages of low cost consumption and high efficiency.
Sawdust Flash Dryer

The structure of Sawdust Dryer
1. Fireplace is the place where the firewood, coal, gas or other material is burning for heat, there is a specially designed buffer which can make the hot air through but provent the fire in.
2. Inlet place is beside the fireplace, thus the material can be dry at a early time
3.. Discharging unit is installed with thermeter to control drying temperature. The temperature change of dryer's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350°C)
4.The cyclone is for the discharging, which is more convenient and air lock for making the discharging little noise and no waste.

Basic feature of Sawdust Dryer

1.Strongly drying strength.All the surface of the particle is the effective area due to the high dispersed in the airflow.
2.Less drying time.
3.Simple structure of the airflow dryer.small footprint,easy construction and maintenance.
4.Large handling amount and high thermal efficiency.When dry the unbound water,the thermal efficiency is up to 60%.

Working Principle of Sawdust Dryer

The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.
