The 2-Minute Rule for FBD principle

Fluidized bed dryers are broadly used in several industries for drying granular and powdered resources. The basic principle requires suspending the fabric in a very stream of air or gasoline, making a fluidized state that enhances the drying course of action.

Furhter, solid circulation monitor is optionally mounted on the exhaust ducting to establish the leakage Or damage to the finger luggage, which may lead to powder reduction.

High pressure drops success due to the necessity to suspend all the mattress in gasoline which equally contributes to significant Power use.

The dryer is mostly made up of stainless-steel. A removable bowl is connected at the base from the dryer that's employed for loading and unloading of material. The stainless steel bowl provides a perforated base of the wire mesh supporting for content which is getting dried.

Admirer motor controls the air tension and carrying capability. When admirer motor speed is improved air velocity is greater and vice versa.

The particles are lifted after which you can tumble back randomly so that the resultant mixture of strong and gas acts similar to a boiling liquid. This situation known as a fluidized state. The excellent gas-sound Get hold of leads to much better heat and mass transfer than in static and shifting beds.

The standard very hot air fluidized bed dryers are certainly not a sensible choice of dryer when handling harmful or flammable solids due website to the fact There exists Hazard of fire or explosion of flammability boundaries are exceeded.

However, In case the powder is sticky Or hygroscopic, you will discover likelihood of powder forming sticky layer to the finger bag area, therefore, simply shaking with the pneumatic cylinder may well not assistance.

Drying: The gasoline surrounds just about every granule to dry them wholly. The air leaves the dryer by passing through the finger bag filter. The entrained particles stay adhered to the inside surface area on the fingers with the bag. Periodically the bag is shaken to eliminate the entrained particles.
