Fluid Bed Dryer

Neelam Industries Fluid Bed Dryer - Granulator combines unique design with unmatched granulation performance. Our system has achieved worldwide success in both the Pharmaceutical and API industries.

Neelam Industries fluid bed dryer is the right combination of an accurate controlled air direction flow with the exact air speed to minimize the pressure drop in the fluid bed,  to ensure a perfectly balanced process preventing granule agglomeration and allowing a uniform fast growing of the granule with low and controlled moisture residual.

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 of Neelam Fluid Bed Dryer.

Salient Feature :

• Inflatable seals with interlocking device to control correct bowl position
• In house R&D for your product development
• Fluid bed granulators available in large variety of capacities
• Perfect control of air turbulence in tangential way with very low pressure drop
• Uniform distribution of binder solution on each single granule
• Fluid bed with the ability to granulate soluble and hygroscopic materials
• Fluid bed with the ability to granulate fine particles
• A more stable, reliable, repeatable, consistent granulation
• Very fast processing time
• No clogging of the guns and filters
• No product loss and high yield
• With the majority of formulations it is possible to avoid the use of the high shear mixer and the sizing mill

Bowl / Product Container

• 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 maneuverability ) which imparts rigidity to carry the product container with the charged load.
• The batch loading capacity is always higher in case of “Neelam Industries” 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.

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.

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.

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 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.

Air Handling Unit
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.

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.

Air filter
Free standing unit constructed from 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 section has a full face external flange for attachment of angle intact, or and extended inletair duct.

Inlet system comprising of 20Micron washable filter. followed by 5 micron prefilter, then pass through , heating coil section 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 upto the control panel.

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

Earthing Device
A standard designed earthing device spring type is provided with the dryer however intrinsically safe earthing device with low voltage relay is also available.

Electro Pneumatic Control Panel
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.
