the machine use for drying powder such as starch, with fast speed.it is very good use for sawdust drying - details see: https://www.machineto.com/xsg-sawdust-flash-dryer-drying-machine-10290403

Principle

Hot air enters into stirring and crushing and drying chamber from the bottom of drier with suitable spouting speed. It exerts strongshearing, blowing, floating and rotating effect. It strengthens the process of heat and mass transfer. At the bottom of drier, 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 steam. During the period of lift, it is dried further. Because gas and solid two phase flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phase is large, so it strengthens the process of heat and mass transfer. Therefore the machine has large drying capacity.
