The exceptional mixing and warmth transfer qualities of such machines make sure uniform drying, thus ensuring excellent and regularity. Simplicity in style and design can make fluidized bed dryers straightforward to operate and keep, consequently They may be the popular choice for a myriad of industrial apps.
The wet solids are lifted from The underside and suspended in a stream of air (fluidized point out). As the new air passes amongst the particles it will require the surplus dampness within the particles thus drying the particles.
Due to the dryer’s shorter drying time and superb mixing motion, no hot spots are manufactured, and better drying temperatures might be realized.
A Fluidized Bed Dryer can be a type of industrial drying procedure wherever a bed of moist granules, powders, agglomerates or pellets are suspended by sizzling air circulation. In this process, the sound substance for being dried is introduced to the fluidized mattress, making a point out exactly where the particles show fluid-like behavior.
In the situation in the FBD method, air or fuel get more info is utilized to fluidize the mattress of particles. This fluidization produces a turbulent and agitated environment, allowing for economical warmth and mass transfer.
Flexibility in Managing Many Products: Fluidized mattress dryers can be employed for lots of products, from foodstuff and pharmaceuticals to chemicals and plastics.
Andritz: A global engineering team giving options for various industries, together with fluidized bed drying methods.
seven. Mechanical and System Design, in addition to, Sizing in the Equipments: Anxiety Examination/ calculations should be completed below varying parameters viz temperature and tension. Similarly, the thickness calculations click here needs to be carried out retaining in mind the static and dynamic loads.
The fluidized bed dryer filter bag is built up of various form of exceptional high quality of fabrics, as per necessity of material involving in drying.
Improved Heat Transfer: The fluidized point out in the mattress allows for improved heat transfer among the drying medium (commonly air) and the fabric getting dried. This economical warmth transfer contributes to lowered drying periods and lessen Strength use, creating FBD a far more Expense-helpful Answer.
The drying process is taking place in more 3 phases until finally and unless the endpoint is attained. At the endpoint, the strong particles moisture amount is equivalent to or a lot less than one%.
Nonetheless, If your powder is sticky Or hygroscopic, you will find odds of powder forming sticky layer within the finger bag area, therefore, just shaking via the pneumatic cylinder may not aid.
Switching the blower unit on is finished within the control panel. After the blower is operational, the air is drawn continually with the Air Dealing with unit and into the tower in the reduced plenum.
