reduce sawdust moisture high temperature drying process

Introduction of high temperature drying process

high temperature drying machine is suitable for drying materials of moisture 20~50%. The rotary dryer is equipped with two 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.

Working principle of high temperature drying process

Hot air enters into stirring and drying chamber from the bottom of dryer with suitable atomizing speed. It exerts strong shearing, blowing, floating and rotating effect to raw material.Therefore raw material is granulated through centrifugating, shearing, impacting and friction effect. It strengthens the process of heat exchange. At the bottom of dryer, the large and damp granule is crushed under the action of stirrer and the granule that is small in particle and contain less moisture will lift accompanied with revolving air stream. During the period of lift, it is dried further. Because gas and solid two phases flow in heat exchange, so the machine has strong drying capacity.

Raw meterial of high temperature drying process

high temperature drying machine is suitable for starch, rice flour, food, chemical, medical industry and other fields for drying powder and thermal sensitivity materials.
raw materials: rice husk, saw dust, wood dust, wood shavings, wood chips, branches, etc. with the diameter less than 3mm and length less than 5mm. The temperature of drying machine ranges from 180°C-250°C.

The structure of high temperature drying process

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.Roller is running evenly to make the material drying and processing at the same time.
4. 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)
5.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 high temperature drying process

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%.
