The excellent mixing and warmth transfer abilities of those equipment guarantee uniform drying, therefore guaranteeing quality and consistency. Simplicity in layout would make fluidized bed dryers uncomplicated to function and sustain, that's why They can be the preferred choice for a myriad of industrial apps.
You will find differing types of fluidized bed dryers, Each individual with its personal style and application. Here are some popular varieties:
The primary principle driving the Functioning of your fluid mattress dryers is, Air is allowed to flow via a bed of sound powdered product in an upward direction. This made so which the velocity is increased compared to location fee of all particles.
While in the pre-heating stage, the mattress’s temperature was rising but In this particular phase, particles stay in the same temperature. It is the scenario due to the fact any Power supplied is taken up via the evaporating molecule as the changeover from the liquid into the gaseous condition.

A supporter is out there at the top from the circulating incredibly hot air. New air enters; filters and warmth exchange are connected serially to heat the air into the demanded temperature.
On the other hand, HEPA filter due to its highly fine mesh ( micron) increases the stress dropo across it and therefore the upper ability suction blower could possibly be necessary to creat fluidization influence.
FBD is made up of a stainless steel chamber using a removable perforated bottom often called the bowl. Content to generally be dry is placed With this bowl. Air is introduced from the bottom of your website bowl and heated at necessary temperature via the heaters.
In a very fluid bed dryer, the inlet air stream is blown past good powder molecules at relaxation. The particles are taken up in the dry & very hot air stream and dehydrated by evaporation.
