In this example, the Stable flow meter performs a vital part to stop products loss from the fluid mattress dryer. when filters are broken powder will come out through exhaust duct exactly where SFM feeling the powder circulation and shut down the dryer.
The air inlet chamber contains a fresh air inlet, prefilter, and warmth exchanger connected serially to warmth the air towards the demanded temperature. The recent air and exit air temperature are routinely monitored in situ. Temperature sensors.
You will find differing kinds of fluidized bed dryers, Every with its individual style and design and application. Below are a few prevalent varieties:
Overall, when the fluidized bed dryer is a potent piece of kit in drying processes, certain restrictions should be thought of prior to their implementation.
The specified or focused conclusion of drying course of action is accomplished by tests decline on drying (LOD) at the end of drying procedure.
This condition is known as fluidized state. Just about every granule is completely dried from the as, which envelops them.
Following a specific time, a force stage is reached through which the friction drag on a particle is equivalent to the force of gravity.
Furthermore, it get more info consists of a surge hopper with a fabric inlet – to feed damp products around the conveyor, a rotary valve close to the hopper – to assist the uniform flow of the material, a gasoline inlet chamber – to permit hot air for drying, an exhaust air duct with blower– to allow efficient regional exhaust air flow, And eventually a dust collector – to gather material dust while in the exhaust air.
The entrained particles continue on to stay on to The within surface with the luggage. Intermittently the bags are shaken to eradicate the entrained particles.
It's then achievable to make use of website scorching air to help with the process of fluidizing the bed. This enhances the drying rate of the material.
Why could it be wonderful? Perfectly, this drying process is Tremendous efficient because it exposes every single particle to your drying medium, making sure reliable dampness elimination. It’s like providing Each and every particle its very own customized spa treatment method!
When the fuel or air velocity is greater, it reaches some extent exactly where the drag force exerted over the particles overcomes their body weight, triggering them to become suspended within the fluidized bed.
Fluidization is the process wherein a granular material in its authentic sound condition transitions into a fluid-like condition utilizing a fluid, which can be air or a liquid. This fundamental principle underpins how a fluidized mattress dryer capabilities, proficiently drying out powdered or granular products.
Substance: Chrome steel is the commonest content for fluidized beds, but other products like carbon steel or Hastelloy can be utilized for distinct apps, impacting the worth.
