The Fluid Bed Dryer has adopted new concept of GMP Regulation with improved performance (drying time is much less than the conventional model) minimum involvement of manual labour simplified maintenance and utilize modular construction techniques to provide flexible installation options.
The process unit is two piece made of SS-304/316 stainless steel. Through mixing of Dry powders, Agglomeration and Drying are carried out in one unit.
The salient feature of Fluidised Bed Dryer are as follows.
1) Process Unit
• The process 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 prepared with a uniform fine texture matt finish.
• All of the product contact surface (SS-304) are 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 are 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 are which exposed each and every particle or the charged batch in the Fluidized air resulting in instant drying.
• 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 form 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 case of “BHAGWATI MACHINES INDIA PVT LTD” Fluid Bed dryer, because of better fluidisation 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.
4) Uniform Lifting Of Container
Product container is lifted by specially designed arrangement with the help of one centrically fitted pneumatic cylinder which ensures uniform lifting throughout the periphery of the container which ultimately gives uniform upward pressure to the solid ‘D’ shaped Rubber Gasket, thereby preventing any leakage during operation.
5) Auto Shaking Device
Pneumatic cylinder is used for auto shaking device of the finger bags is mounted on the body and is fitted with a wire rope made out of S.S. 304 guided by pulleys thus rendering the shaking extremely efficient. It also brings down the finger bags to such a level that these can be inspected very easily form the bottom of the retarding chamber. If the shaking is not efficient , the particles will be retained in the finger bags and there will be no proper fluidisation resulting in formation of lumps in the products container.
