Fluid Bed Dryer R&D Lab Model

Fluid Bed Dryer R&D Lab Model

Lab Fluid Bed Dryer (small dryer) with fluidized bed granulation machine is ideal for pilot scale & R&D lab with updated design makes it truly versatile for Pharmaceuticals, Food, Dyestuff, Chemical, API, Bulk Drugs and Polymer Industries. Fluid Bed Dryers are designed to Uniform drying of the material at low temperature. All contact parts are made of SS 304 / 316 / 316L. The complete unit is supplied with Suitable motor, blower, filters, filter bag, control panel. Heating system provided as per specific customer requirements.

We are R&D Fluid Bed Dryer manufacturer in production capacity of 5 liters, 10 liters and 20 liters. We also manufacture Fluid Bed Processor and Fluid Bed Coater with spray purging arrangements for pilot lab scale operations.

Fluid Bed Dryer Working

A 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.


Control System

Manual Control:

Inlet, Outlet, Bed (Optional) Temperature, Heating & Cooling Timer, Filter Bag Shaking On & Off Timer, Damper On & Off Timer.

Auto Control:

  • PLC based with touch Screen and password level to feed the parameter of process for Heating/Cooling & Bag Shaking Timing etc.
  • Pre stored process parameter will help to achieve consistent product quality.
  • HMI (Touch Screen) for visualization of machine of specific process condition and data.

PLC Indicates:

  • Visualization of Machine process condition & date.
  • Alarm Signal
  • Fault Message

SCADA Package (optional)


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.

Fluid Bed Dryer Validation

A complete documentation support in terms of DQ / IQ / OQ / FAT / SAT.

We provide necessary support for installation commissioning and start-up of the machine at site.
