DESCRIPTION:

The 'KOTHARI PHARMA LTD' FLUID BED DRYER are ideal for production, pilot scale & R&D lab with latest Improvement in design makes this unit a truly versatile one for Pharmaceuticals, Food, Dyestuff, Chemical, API, Pesticides, Bulk Drugs and Polymer Industries. All contact parts are made of SS 304 / 316 / 316L

OPERATIONS:

Batch of product loaded into the material bowl is seated in the chamber & heated filtered air is drawn through the product. By this, the entire surface of individual particle is surrounded by the hot air thus achieving a homogeneous distribution of temperature and as a result of this, a rapid and careful drying down to the smallest- residual moisture. Escape of material from the granulation chamber is prevented by exhaust filters, which are periodically agitated or purged to reintroduce the collected material into the fluidized bed. The product can be cooled and the material container exchanged for the next batch.The quantity of air is regulated by means of outlet air damper only.

DRYING TIME:

The drying time depends on various factors such as physical properties of material, moisture content, type of moisture (free or inherent of water or crystallization) drying temperature etc.For example the crystalline product can be dried faster than amorphous product containing same percentage of moisture at same temperature.

Pharmaceutical granules & powder having approximately 20% to 25% moisture can be easily dried. Fluid Bed Dryers are normally supplied either with Electric Heating or with Steam Heating. However hot water / hot oil circulation system can also be installed.
