Mini – FBD – FLUID BED DRYER MACHINE ( cGMP / R & D MODEL)
Purpose : Fluid bed dryer is a process unit for Drying of granulated materials for solid dosage forms in batch operations.
BOSON Fluid Bed Dryer offers an effective and efficient method for drying & granulating. By using modular construction and simplified design, we provide flexible installation.
cGMP : FBD is designed to achieve all the requirements of cGMP – Current Good Manufacturing Practices. The components are easily dismantable, can be cleaned thoroughly and assembled in quick time. It is invented keeping in mind the latest cGMP norms with all contact parts AISI 316 Quality.
Process Chamber / Unit
The Process Unit is two piece , made of stainless steel 316 Material / The finish employed externally will be all welds ground back and polished into the surrounding materials. All of the product contact surface (SS-316) are mirror finished & All of the external surfaces of the Dryer and all non contact/sight parts will prepared with a uniform fine texture matt finish / 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 / Window – Bull eye windows with toughness glass & Lamp for process chamber
Bowl / Product Container
Product bowl is a conical shaped manufactured form SS-316 grade stainless steel having stainless steel mesh ( Sieve Dutch Weave SS-316 ) 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 “BOSON” 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.
Inner Surface – Mirror Finis & Outer Surface – Matt Finish / All Standard Features Like – Temp. measuring port , sampling port , bull-eye window & disconnect type bottom screen .
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 aluminium anodisedl 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 section has a full face external flange for attachment of angle intact, or and extended inlet air duct. Inlet system compression of 20 Micron 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 Transtion 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.
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 Process Timer Blower motor, start & stop. Compressed air pressure quages. Filter bag shaking timer Solenoid valves etc. R.Y.B. for Phase indication MCB for motor & power ON/OFF Contactor , Relay . ect……
