The equipment is designed by combining airstream crash with vortex flash vaporization dry-two dry theories. When the material and hot air mix up in the drying tube, they could go ahead at high speed in parallel with two suspended states and crash head-on in a coaxial container. The material pellets of airstream penetrate in the windstream because of the inertia, which gradully decelerates inthe certain distance and acclerates along the opposite direction and penetrates the original jet flow. After so many damped vibrations, they deviate from the crash zone and flow out directly.

The heavy material containing more moisture in the vortex dryer revolves along the outer wall at high speed and crushed by the blender in order to increase the relative velocity and strengthen the effect of heat transfer. The material containing regular moisture discharges from the center to the up. The gas and the products are discharged separately through the gas and solid separator.

At present it is the first choice for drying high moisture and bulk materials
