Description: Fluid Bed Dryer / Fluid bed processors



  • The process unit is single pieces welded design, made of stainless steel of SS.
  • All process contact parts are made of SS – 316.
  • 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.
  • The entire product contact surface 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 are made of single piece construction from SS 316 quality steel. Below that is the retarding chamber made out of S.S. 316 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.
  • Product bowl is a conical shaped manufactured form SS-316 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 manoeuvrability) which imparts rigidity to carry the product container with the charged load.
  • The batch loading capacity is always higher in case of “BHAGWATI” 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.




  • 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.




  • 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.




  • 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.




  • Blower and filter with heating arrangement are housed in the rear chamber.
  • They can also be housed the services zone to avoid sound pollution as well as to avoid interference of the maintenance people in the production zone.




  • As per international practices the fluid bed dryer equipment is provided with a rapture disc as measures of explosion Vent, Tested at 2 Bar pressure, mounted on the side of the dryer.




  • A std designed earthing device spring type is provided with the fluid bed dryer however intrinsically safe earthing device with low voltage relay is also available.




  • A free standing steel control panel having the following controls.
  • Inlet air temperature controller.
  • Exhaust air temperature indicator
  • Product bowl lifting & lowering valve.
  • Process air Damper regulation
  • Blower motor, start & stop.
  • Compressed air pressure Gauges.
  • Filter bag shaking timer
  • Solenoid valves etc.
  • Semi-automated and fully automated PLC and PLC/PC control system are available for selection at an appropriate level of additional cost. (OPTION).


  • Centrifugal type blower fan with dynamically balanced impeller and backward curved blades.
  • All Stainless steel construction.
  • Direct coupled none—flameproof electric drive. Anti –vibration mounting and independent sub-support frame.

A fluidized bed dryer (also called a fluid bed dryer) is a process equipment used extensively to reduce the moisture content of food, pharmaceutical, chemical powder, and granules.

The machine is known for drastically decreasing the drying time of drug compounds, typically greater than 50 microns, used for tablets and capsules.

Traditionally, manufacturers used trays and vacuum dryers to remove moisture from Active Pharmaceutical Ingredients.

Both Tray and Vacuum Dryers are insulated tray chambers placed on top of each other in trolleys. The material to be dried is placed in the trays. Electric heaters and blow fans ensure heat transfer by circulating hot air in tray dryers.


  • Free standing unit constructed from aluminium anodised frame work (SS-304) with doubled skinned panels. All wall panels are cross based for added strength. Quick release panels provided for inspection and maintenance access.
  • The air intake SBFBD-tion has a full face external flange for attachment of angle intact, or an extended inlet air duct.
  • Inlet system consists of 20 Micron washable filters, Followed by 5 micron profiler, then pass through, heating coil SBFBD-tion containing a full air duct steam operated heater battery, constructed with stainless steel tubes and headers and a steel casing (SS-304). The moving process air passes through the steam heater to achieve the desired temperature. to match the inlet to the processing unit.
  • PT 100 temperature sensing probe will be fitted into the air Transition duct and will be connected up to the control panel.

The pharmaceutical industry has arguably the most use from fluid bed dryers. The powder processing field in the industry has long replaced conventional drying trays with this automated mechanism.

Spray granulation uses fluidized bed dryers, the conversion of the water-containing solution, paste, suspension, or a melt into a granule form without any chances of product contamination or dust pollution.

Since it is challenging to transport fine powders due to loose packaging, dryers also assist in agglomeration, a process of amassing material fines into cohesive units like pellets or granules. This process makes transportation and delivery easier on logistics.

Fluidized Bed Dryers are used in powder layer coating using tangential roto granulator to mini-tablets and capsules. Polymer-coated tablets and capsules allow patients to easily swallow without any issues. Simultaneously, a fluid bed dryer dries pellets used for OSDs layering. Often the applied layers are significantly thicker, requiring precise control over the density of powder used.

Additionally, fluidized bed dryers are particularly popular as drying mechanisms in industries like:

  • Chemical
  • Pharmaceutical
  • Dyes
  • Food
  • Dairy
  • Metallurgical

Fluidized bed dryers provide an efficient solution for gentle and uniform materials drying.
