fluid bed dryer manufacturer and supplier

Salient features

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/ PRO DUCT 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 BOMBAY 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 extermely 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 efficent , 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.

6)AIR HANDLING UNIT Blower and filter with heating arrangement are housed in the rear chamber .

fluid bed dryer india

The fluid Bed Dryer are most suitable for drying granular crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, food and allied products. The fluid Bed dryer is not suitable for drying liquid or pasty materials.

• Fluid bed dryer is designed to introduce the hot air stream at the base of the product container which is filled with the Fluid Bed Dryer material.

• Induced draught is created by means of blower and fresh air is sucked in to the unit. This hot air system expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidization and offer conditions which are almost ideal for drying.

• Fluidization produces full agitation of solid particles and since each particle gets surrounded by hot air, heat transfer is extremely high and uniform.

• The product is dried fast without appreciable loss of heat. Filter bags prevent particles escaping from the dryer.

• Fluid Bed Dryer occupy lesser floor space compare to conventional dryer and are very easy to operate and can dry material in least time as compared to tray dryer.

• In fluid Bed Dryer, temperature distribution through out the product is uniform and the heat transfer rate is very high. High production rates are achieved due to reduce drying time.

• As the product is in close contact with drying air at low temperature and also for short duration, the physical and chemical properties of the products are generally not effected and therefore the dryer can effectively be used for heat sensitive products.

• Due to the continuous movements of product during drying lump formation, case hardening etc. are minimized.
