In this article’s how it works: The fabric to be dried is placed in a mattress, and sizzling air is blown from underneath.
FBD bowl loading: Within a tablet production method, The full operation of the Fluidized bed drier commences Along with the loading of damp granular content with the granulator. The moist granules for being dried are put during the detachable bowl of a vertical FBD.
The polyester cartridge filtration is anti-static. Blowing in the strains with compressed air or washing with h2o.
Contemporary air is permitted to pass through a prefilter right before dealing with a heat exchanger to be heated. The underside with the bowl is exactly where the new air passes via. Concurrently enthusiast is permitted to rotate. The air velocity improved step by step.
During the pre-heating stage, the bed’s temperature was rising but On this phase, particles remain in the identical temperature. It's the circumstance due to the fact any Electricity equipped is taken up from the evaporating molecule as being the changeover on the liquid towards the gaseous state.
Should the processing of following batch usually takes in excess of forty eight hours then clean up the products (Sort A cleansing).
Correct Management and checking of approach parameters read more are important for attaining best results in the FBD approach.
Andritz: A global technology group offering solutions for a variety of industries, which includes fluidized mattress drying methods.
Refreshing air inlet, prefilter and heat exchanger are linked serially to warmth the air on the needed temperature.
Loading of supplies consists of introducing a clean batch of wet granules to the products chamber by way of detrimental pressure feeding, products is often sucked within the superior shear mixer chamber by way of a feeding tube.
Enhanced Heat Transfer: The fluidized condition of the mattress allows for enhanced warmth transfer involving the drying medium (usually air) and the material staying dried. This efficient warmth transfer contributes to lessened drying instances and reduced Power use, creating FBD a far more Price-productive Answer.
Once the velocity of click here the air is larger compared to settling velocity of granules; and lower than the velocity for pneumatic conveying, the solids are buoyed up and come to be partially suspended in the gasoline stream.
SS filters are created of stainless-steel and also have fine perforations which protect against very pleased decline and allow air to move. Bag filters are created of canvas cloth.
Bag filters are also called candle filters or finger bag filters. The fluid mattress dryer that has stainless-steel filters is equipped with blowback method which eliminates the powder attached with filters and stops blockage of filters.
