Inlet air is blown up from the static electric power bed since the velocity of your air increases so does the Place concerning powder particles until the particles turn out to be suspended within a mattress the fluidization procedure is through to take place in 5 phases like clean fluidization, bubbling fluidization, turbulent fluidization and very first fluidization.
On heating, the recent air is blown throughout the perforated distributor plate situated at The underside of the most crucial equipment housing device. This process brings about an upward stream of air that passes through the merchandise mattress.
A rise in the bubble measurement of your bed occurs with an increase in the air velocity. The functionality in the fluidized mattress dryer dominates via the velocity read more from the gasoline compared to temperature.
In the event the blower is useful it draws and increases airspeed in the fluidized mattress dryer. The airflow has incredibly modest factors referred to as fines. If these particles move the filter bag so They are going to be expelled to the surface encompassing surroundings.
It can even make the supplies a lot more appropriate for managing and it helps in correct preservation of your elements.
Fluid bed dryers use higher levels of hot fuel and air Therefore making it tricky to dry poisonous or flammable materials.
