Fluid Bed Dryer (FBD)
Fluid Bed Dryer (FBD)
TFluid Bed Dryer has adopted the new concept of GMP Regulation with improved performance (drying time is much less than the conventional model) minimum involvement of manual labor simplified maintenance and utilize modular construction techniques to provide flexible installation options.
The processing unit is two-piece made of SS-304/316 stainless steel. Through the mixing of Dry powders, Agglomeration and Drying are carried out in one unit of “THE BOMBAY ENGINEERING WORKS” Fluid Bed Dryer.
The salient feature of the Fluid Bed Dryer is as follows.
1) PROCESS UNIT
- The processing unit is two-piece, made of stainless steel of SS-304 GRADE.
- All process contact parts are made of SS-304 grade.
- The finish employed externally will be all welds ground back and polished into the surrounding materials.
- All of the external surfaces of the Dryer and all non-contact/sight parts will prepare with a uniformly fine textured matt finish.
- All of the product contact surface (SS-304) is mirror finished.
- Particular attention has been paid to reduce any source of material Entrapment by mirror polishing flush all welds to create crevice-free profiles both internally and externally.
- The expansion chamber containing the filter finger bags & dished end is made of single-piece construction from SS-304/316 quality steel. Below that is the retarding chamber made out of S.S. 304 Retarding chamber is locked with the explosion chamber by means of clamps. The length of the retarding chamber is such designed, thereby providing extra-large heat exchange area which exposed each and every particle or the charged batch in the Fluidized air resulting in instant drying.
- The specially designed base is provided for air vortex effect and to give added strength.
- A central drain is provided in the base to release wash water.
2) BOWL/ PRODUCT CONTAINER
- Product bowl is a conical shaped manufactured from SS-304 grade stainless steel having stainless steel mesh support along with fine finish air mesh.
- The product container Trolley is of Tubular construction made form SS-304 pipe mounted on polypropylene castor wheel (2nos fixed & 2nos. Swivel for maneuverability ) which imparts rigidity to carry the product container with the charged load.
- The batch loading capacity is always higher in the case of “BOMBAY” Fluid Bed dryer, because of better fluidization by varying the frequent shaking of the finger bags. Shaking period vary depending on the nature of products.
3) RUBBER GASKET
A solid ‘D’ shaped food type silicon rubber gasket is provided in the groove of the flanged joint (between the product container and the retarding chamber) to prevent any leakage of air with fines during operation.
BLOWER
Centrifugal type blower fan with dynamically balanced impeller and backward curved blades. All Stainless steel construction. Direct-coupled non—flameproof electric drive. Anti-vibration mounting and independent sub-support frame.
