Working Principle of a Fluid Bed Dryer:
- Fluidization: Hot air is introduced from the bottom of the dryer through a perforated plate, lifting and suspending the particles, creating a “fluid-like” state.
- Drying: As the hot air flows through the fluidized particles, moisture is evaporated and carried away.
- Exhaust: Moist air exits the system via a dust collector or exhaust filter.
Drying Time:
The drying time depends upon various factors such as physical properties of material, moisture content, type of moisture (free moisture or water of crystallization), drying temperature etc. The crystalline products can be dried faster than amorphous product containing same percentage of moisture at the same temperature. Generally pharmaceutical granules or crystals containing free moisture of about 20% to 25% can be easily dried in about 30 to 40 minutes at a temperature of about 75-degree C. Certain crystalline materials containing about 40% of moisture can be dried in Fluid Bed Dryer within 35 to 45 minutes.
Filteration:
Single stage filtration of 20 microns PP cloth filter, P.P. filter bag for exhaust air, also multi stage filtration can be given on demand. Positive Earthing Arrangement, explosion flap are given as a part of standard features.
Air Handling Unit:
20 Micron Pre filter, 5 Micron, 0.3 Micron Hepa Filter with either electrical heating or steam heating.
Key Features:
- Uniform drying due to even distribution of hot air through perforated plates.
- Enhanced heat and mass transfer.
- Rapid moisture removal due to constant contact between hot air and product.
- Suitable for heat-sensitive materials due to low drying temperatures.
- Precise control over inlet and outlet air temperature ensures product stability and quality.
- Available in various sizes from lab-scale to large industrial models.
- Designed to meet Good Manufacturing Practices (GMP), especially in pharmaceutical production.
- Minimizes risk of over drying or under drying, ensuring consistent moisture content.
- Designed with smooth surfaces, minimal dead spots, and often includes CIP (Clean-in-Place) systems.
- Flameproof construction.
- Integrated PLC systems, HMI panels, temperature sensors, and emergency shutdown features.
- Filter bags and exhaust systems minimize dust and airborne particles, protecting both the environment and operators.
- Easily upgradable and customizable depending on capacity and process needs.
- Efficient drying process reduces energy usage compared to traditional drying methods.
- Uniformity in drying and reduction in drying time.
- Air suction and discharge dampers provided to control the inlet and outlet air flow.
- Timer provided to set the process time which will cut off the motor supply after pre-set time period.
- Atmospheric inlet air is filtered by means of single / multi stage filters of 20 microns to prevent any fine dust to pass through the product.
- Steam Coil made out of 1” dia. SS 304/316 finned tube & is designed to get pressure of around 3-4kg./cm^2 (working pressure 3 kg/cm^2).
- Digital temperature indicators cum controller is provided with the unit to indicate the inlet and outlet air temperature as well as to controller the present inlet air temperature.
- An explosion safety flap of adequate capacity at the rear end of the dryer and an positive earthing point to prevent static charge in the machine are provided.
