As the new air passes by container granules begin to suspend within the air to become dry (termed a fluidized state), the procedure is named fluidization.
The air is filtered throughout the filter then passes through the bed of the fabric at The underside.
seven. The air leaves the dryer by passing from the bag filter. The entrained particles remain connected into the interior floor on the finger bags. The bag is shaken periodically to get rid of the attached particles.

What's more, it consists of a surge hopper with a cloth inlet – to feed wet products around the conveyor, a rotary valve close to the hopper – to aid the uniform stream of the fabric, a fuel inlet chamber – to permit hot air for drying, an exhaust air duct with blower– to allow productive regional exhaust air flow, And eventually a dust collector – to gather product dust during the exhaust air.
Contemporary air inlet, prefilter and warmth exchanger are related serially to heat the air to your necessary temperature.
The suitable option of distributor utilised in the drying course of action more info makes certain even and steady fluidization.
Soaked particles are suspended in very hot and dry air stream. Moisture about the particles surface evaporates as warmth flows through the system (traditional heating) the speed of drying slowly but surely will increase as the particles soak up extra heat.
