The drying procedure can take spot in 3 levels until finally the tip position is achieved (At the tip level the sound particles moisture amount is equivalent or less than 1%)
The moist solids are lifted from The underside and suspended in the stream of air (fluidized point out). As the hot air passes concerning the particles it takes the excess humidity from your particles thus drying the particles.
Senieer: A renowned Indian maker featuring an array of fluid mattress dryers from lab-scale to manufacturing scale.

The heated air is released right into a chamber beneath the vibrating conveyor deck. It passes from the perforated conveying surface, in the fluidized bed of solids, and into an exhaust hood.
five. Right after some time, a degree of pressure is reached at which frictional drag about the particles is equivalent to your drive of gravity.
