A major facet of this method would be that the granular particles are in regular movement inside the fluidized condition, which ensures uniform drying.
The Doing the job principle of fluidized mattress dryers is “the entire process of fluidization”. At the beginning, incredibly hot air is launched at higher pressure throughout the bed of sound particulate. This air passes through the reliable particles at a velocity sufficiently higher to suspend the solid in a completely fluidized state.
Hybrid Fluidized Bed Dryers: These dryers combine characteristics of fluidized bed and other sorts of dryers, like tray dryers or rotary dryers.
Contemporary air is permitted to pass through a prefilter ahead of dealing with a heat exchanger to generally be heated. The bottom with the bowl is the place the hot air passes as a result of. Concurrently admirer is permitted to rotate. The air velocity greater slowly.
Alternatively, vacuum conveying can be performed by connecting the product container which has a tube and developing destructive tension for suction using a vacuum transfer method. Soon after drying, another procedure is milling.
This point out is generally known as fluidized state. Every granule is extensively dried because of the as, which envelops them.
In fluidization course of action, warm air is introduced at more info higher strain via a perforated bed of moist strong particulate.
We must always, therefore, go for the fluid mattress dryers with electrical earthing components to stay away from this problem.
Right after completion of exercise change the standing of space and affix dully stuffed and signed status label on the FBD.
Loading of products includes adding a refreshing batch of damp granules in the merchandise chamber by means of destructive tension feeding, products might be sucked from the superior shear mixer chamber via a feeding tube.
A enthusiast is out there at more info the best of the circulating scorching air. Refreshing air enters; filters and warmth Trade are related serially to warmth the air on the essential temperature.
Granules and hot gas are completely mixed, leading to consistent temperature, chemical composition, and particle dimension distribution. Drying is achieved at a constant price & the period of falling fee is very transient.
The dryer is product of SS316, an austenitic chromium-nickel chrome steel containing a deliberate volume of molybdenum, expanding general corrosion. The construction of the Vertical fluidized mattress dryer is demonstrated from the determine under.
Environmental air is processed by the processing device, in processing device air is filtered through distinct filters. To start with air go-by means of coarse filters or even the mesh filters also called primary filters. Soon after mesh filters air go-via secondary filters or bag filters.
