FLUID BED DRYER/ FLUID BED PROCESSOR
Alliance fluid bed dryers and processor are manufactured in modular construction mainly consisting of main processing (drying) unit and separate inlet air preparation unit and separate exhaust air unit giving flexible and alternative installation option to the customers as per requirement.
Fluid bed dryers are most suitable for drying granules, crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, foodstuff and allied industries.
Fluid bed processing involves drying, agglomeration, granulation, and coating of particulate materials. It is ideal for a wide range of both heat sensitive and non-heat sensitive products. Uniform processing conditions are achieved by passing hot air through a product layer under controlled velocity conditions to create a fluidized state.
Using intimate air-to-product contact, Drying is carried out by heated air supplied as main the source for drying, as it is effectively introduced by steam heating which gives high rates of heat exchange at high thermal efficiency while preventing overheating of individual particles.
Fluid bed coating of powders, granules, or tablets involves the spraying of a liquid on the fluidized powder under strictly controlled conditions. It is ideal equipment that is in conformity with the requirements of cGMP.
CAPACITY
- Fluid bed dryer/ Fluid bed processor comes with range of capacities as per our customer’s requirement.
- Capacity range: - 5 Kg to 500 Kgs
OPERATON
The wet material is loaded into the product container which is provided with air distributor plate and Dutch weave mesh. Fresh air-to-product-contact is filtered by means of 3-Way filtration process i.e. through coarse filter , 5 micron filters and the HEPA Filter is heated by means of heater (steam or electrical). This hot air then passes through the product container, creating turbulence in the product and hence product moves up and down in the product container. Due to this the heat transfer is quick and the product is dried fast without appreciable heat loss. Filter bag prevents particle escaping from the dryer.
APPLICATION:
- Suitable for drying humidity from powder raw material in Pharmaceutical, foodstuff, feed, chemical industries, etc
- Semi-liquid materials, large granules, small blocks and adhesive material.
- The materials that volumes vary during drying process.
- Fluid bed Dryer can be supplied with Upgradation to be used as processor(Vertical Spray Granulation)
- Pharmaceuticals granules or crystals containing free moisture can be easily dried as per customer’s requirement.
