Working Principle:

The flash dryer is a continuous drying equipment specially designed for filter-cake-like, paste-like, and slurry-like materials. The clean heat medium enters the drying chamber from the tangential direction, and forms a powerful vortex rotating airflow together with the mechanical stirring mechanism. The wet material is fed into the drying chamber quantitatively by the feeder and crushed and dried under the action of stirring and vortex airflow. The top of the drying chamber is equipped with a particle size classifier. The fine powder is discharged from the top of the tower and collected into the product by the subsequent separator. The larger particles are returned to the drying chamber and continue to be crushed and dried.

Product Features:

Ø  Dry viscous material: the lower part of the dryer is in a cone structure and has a crushing device plus air flow to wash the wall of the device, so it can handle a certain viscous material.

Ø  Dry heat-sensitive materials: Due to the short drying time, the relative speed of the material and the hot air is large and the hottest air does not directly contact with the dry material, so it can be used to process heat-sensitive materials.

Ø  High drying strength: due to the crushing, scouring and collision of materials during the drying process, the surface area increases: at the same time, the hottest air does not directly contact the dried materials, and the inlet air temperature can be higher than the melting point of the materials, so the equipment has high drying strength.

Ø  Effective control of final moisture and fineness: the built-in objects (swirl blade, ceramic ring or classifier) are set through the drying tower, and coordinated with the inlet air temperature, which can effectively control the final moisture and finished product fineness.

Ø  Environmental protection compliance: The system operates under slight pressure, and adopts different dust removal methods and materials according to different materials (pulse bag filter, wet scrubber, venturi wet dust collector, etc.), which can eliminate environmental pollution.

Ø  Dry viscous materials: According to different materials, the feeder and the discharger adopt different forms, which can achieve automatic, continuous feeding and smooth discharge requirements.

Ø  Optimal power matching: according to different material properties (density, bulk density, viscosity, fineness, initial moisture, final moisture, angle of repose, etc.), matching blower, induced draft fan, agitator, feeder, etc., to match the power optimal.
