Principle

The hot air enters the stirring, pulverizing and drying chamber from the bottom of the dryer through the inlet pipe at a suitable jet speed, and produces strong shearing, blowing, and rotating effects on the material, so the material is centrifuged, sheared, collided, and frictionally divided into particles, which enhances mass and heat transfer. 

At the bottom of the dryer, the larger and wetter granules are mechanically broken up under the action of the agitator, and the granules with lower moisture content and smaller particle size are entrained by the rotating airflow to rise, and are further dried during the rising process. 

Because the gas-solid two phases are rotating, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the two phases of the solid and the gas is relatively large, which strengthens the mass transfer and heat transfer between the two phases, so the machine has high production strength.

Feature

• The organic combination of swirl, fluidization, spouting and crushing classification technology.

• The equipment is compact, small in size, high in production efficiency, continuous production, and realizes "small equipment, large production". 

• High drying intensity, low energy consumption and high thermal efficiency. 

• The material has a short residence time and the finished product is of good quality, which can be used for drying heat-sensitive materials. 

• Negative pressure or micro-negative pressure operation, good airtightness, high efficiency, and eliminate enviromental pollution.
