Usefulness of air-stream crash dryer

Air-stream crash dryer, is a kind of new energy-saving drying equipment, which is declared as Chinese national invention patent. The main fuel is coal or gas. The freezing air becomes dry hot blast through the hot air-stream stove, which is appearing as suspended state with bulk material. It causes the gas and solid to go forward at higher speed in parallel. At the same time the water is vaporized in order to dry material.

Features of air-stream crash dryer

(1) when the wet 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, damped vibration. Then they go to air blower for refinement. The drying area of material is increased. And the heat efficiency is improved .

(2) Material is delivered from air blower to vortex room. After fineness, the heavy material containing more moisture revolves along the outer wall at high speed, in order to increase the relative velocity, strengthen the effect of heat transfer, and improve the heat transfer confident of the volume. The material containing regular moisture discharges from the center to the top. The feature of this plant is good quantity of drying, high effect of heat transfer, and low energy source consumption. The height of this plant is lower 50% than tower type starch dryer.
