In this example, the Reliable stream meter performs a crucial function to prevent item decline from the fluid mattress dryer. when filters are damaged powder will come out by exhaust duct exactly where SFM sense the powder flow and shut down the dryer.
As the recent air passes via container granules start to suspend during the air to become dry (known as a fluidized condition), the process known as fluidization.
In the event the gasoline-particle frequent is great, it may result in efficient heat and mass transfer rates, which ends up in more quickly elimination of humidity.
When this happens every one of the sound particles will get blown up and become suspended within an air stream. The good bed is Therefore transformed right into a boiling liquid which is recognized as the fluidized state.
Dampness Removing: The humidity-laden air rises in the fluidized bed, carrying the evaporated humidity with it. This steady circulation of air in the mattress ensures uniform drying.
A rise in the bubble dimension on the bed happens with a rise in the air velocity. The operation in the fluidized mattress dryer dominates by the velocity on the gas in comparison to the temperature.
Fluidized Bed Dryer is engaged on the principle of fluidization on the feed material. Fluidization is definitely the introduction of hot air at substantial tension by way of a perforated bed of moist strong particles.
Horizontal Fluidized Mattress Dryers: These dryers Use a horizontal drying chamber. They're effectively-suited for components which can be simple to fluidize and do not demand a significant drying temperature.
When the velocity of air is bigger compared to the sedimentation fee more info of the granules, the granules remain suspended during the gas stream.
Amongst the principal benefits of fluidized mattress dryers is their effectiveness. The intense mixing in a fluidized bed makes certain in the vicinity of-ideal circumstances for the two heat transfer and mass transfer, resulting in higher thermal effectiveness.

In batch fluidized mattress dryers, a specific quantity of material is loaded in to the dryer, plus the drying process occurs within a batch-wise method. When the drying cycle is finish, the dried product is removed, and the next batch is loaded.
Bag filters are also check here referred to as candle filters or finger bag filters. The fluid mattress dryer which has stainless-steel filters is equipped with blowback method which removes the powder hooked up with filters and prevents blockage of filters.
