Riddhi Fluid Bed Dryer 60, 120, 250,500 KGS


SPECIFICATION
IT IS THE ONLY CGMP MACHINE AVAILABLE IN INDIA

The Riddhi 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 utilises modular construction techniques to provide flexible installation options.

The process unit is single piece made of SS-316 stainless steel. Thorough mixing of Dry powders, Agglomeration and Drying all are carried out in one unit of Riddhi Fluid Bed Dryer.

The Outstanding Main Points of Riddhi Fluid Bed Dryer are as follows :

PROCESS UNIT

  • The Process unit is of single piece, made of stainless steel of SS-316 grade.

  • All process contact parts are made of SS-316 grade.

  • The finish employed externally will be all welds ground back and polished into the surrounding materials.

  • All of the external surfaces of the processor and all non contact/ sight parts will prepared with a uniform fine texture matt finish.

  • All of the product contact surface (SS-316) 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 retarding and the expansion chamber containing the filter finger bags are made of single piece construction from SS-316 quality sheet. The length of the Expansion chamber is much more compared to retarding chamber, thereby providing extra large heat exchange area which exposes each and every particle or the charged batch in the Fluidised air resulting in instant drying.

  • Side entry inlet air duct at the rear.

  • Two 304 Stainless Steel support columns are provided for stability. The Support columns designed to withstand a 30 ton vertical force.

  • Specially designed base is provided for air vortex effect and to give added strength.

  • A central drain port is provided in the base to release wash water.

BOWL / PRODUCT CONTAINER

  • Product Bowl is a conical shaped manufactured from SS-316 grade stainless steel having stainless steel mesh support along with fine finished air mesh.

  • The product container Trolley is of Tubular construction made from SS-304 pipe mounted on polypropylene castor wheel (2 Nos. Fixed & 2 Nos. Swyvel for maneurverability) which imparts rigidity to carry the product container with the charged load.

  • The batch loading capacity is always higher in case of Riddhi Fluid Bed Dryer, because of better fluidisation by varying the frequent shaking of the finger bags. Shaking period vary depending on the nature of product.

RUBBER GASKET
A solid ‘U’ shaped food grade 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 shifted by specially designed arrangement with the help of one special Tee shaped Rubber with stainless steel inner and outer guard operated pneumatically which ensures uniform Lifting throughout the periphery of the container which ultimately gives uniform upward pressure to the solid ‘U’ shaped Rubber Gasket, thereby preventing any leakage during operation.

The release of the product container at the end of operation is effected smoothly by incorporating a specially designed vacuum generator in the system.

SAFETY CLAMP LOCKING
Pneumatically operated safety Clamp locking system is provided for the product container, with interlocking arrangement which will hold container flanged joints continuously to prevent any leakage during operation. This locking arrangement is an extra safety measure against any explosion.

AUTO SHAKING DEVICE
Pneumatic cylinder is used for auto shaking device of the finger bags is mounted on top thus rendering the shaking extremely efficient. It also brings down the finger bags to such a level that these can be inspected very easily from the bottom of the retarding chamber. If the shaking is not efficient, the particle will be retained in the finger bags and there will be no proper fluidisation resulting in formation of lumps in the product container.

FILTER BAG LOCKING TUBE
A groove is provided in the retarding and expansion chamber impart rigidity also to fit in an air tube with hanging ring (filter bag locking tube) of the finger bags with interlocking device (easily removable for cleaning or replacement). When expanded the air tube sticks to the cylindrical surface of the filter holding chamber to prevent by passing the fines emission and ensure arresting of fines in the finger bags. Inspection sight glass is provided within the side wall of the expansion chamber.

FLUIDISATION CONTROLLER
An Auto Damper controller, operated pneumatically, is provided on the suction air ducting of the blower to control the pattern of fluidisation. This helps

  • To avoid generation of more fines.
  • To have desired pattern of fluidisation for the materials of varying bulk density by varying the quantum of suction air.
AIR HANDLING UNIT
Blower and Air filter with heating arrangements are housed separately in the service 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 mild steel construction with stove enamel paint finish.
  • Direct coupled non-flameproof electric drive motor. Anti-vibration mountings and independent sub-support frame.
  • A sound attenuator will be fitted to keep noise emissions to 
    < 75 dB.

Air Filter
Free standing unit constructed from stainless steel 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 comprising of 20 Micron washable filter, 20 Micron washable filter is 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 and then finally preceded by HEPA FILTER of 0.3 micron (option) to match the inlet to the processing unit.

A 304 Stainless steel transition section is fitted to convert the inlet air duct from a square to a round configuration 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 measure of Explosion Vent, Tested at 2 Bar pressure, Mounted on the side of the Dryer.

EARTHING DEVICE
A specially designed earthing device is provided with interlocking system to Eliminate the electrostatic charges which develop due to at-random movement of fines emission.

A free standing stainless steel control panel having the following controls :-

  • Inlet air temperature controller.
  • Exhaust air temperature controller.
  • Product bowl rotary valve locking & release.
  • Process air damper regulation.
  • Blower motor, start & stop.
  • Compressed air pressure gauges.
  • Filter bag shaking timer

PROGRAMME LOGIC CONTROL SYSTEM
Semi-automated and fully automated PLC and PLC/PC control system are available for selection at an appropriate level of additional cost. (OPTION)
