About Fluidisation And Fluid Bed Heat Transfer Unit

^{FLUIDISATION AND FLUID BED HEAT TRANSFER UNIT}

DESCRIPTION :

This is a dryer in which moisture removal takes place by fluidization of solids particles by hot air. The set-up fitted with a specially designed, vertical Glass Column. The lower portion of the column is filled with fluidizing material. The material is supported on the screen mesh held between two flanges. Air from a compressor is heated in the heater box and passed through the column. Flow control and by-pass valve are fitted to regulate the airflow. At the top outlet of column a cyclone is provided to collect any solid particles taken out by the air stream.

EXPERIMENTATION:
To study the fluidized bed drying.
To plot the drying curve under fluidized bed condition.

Superior Measurement and Control

Equipped with digital LCD readout and both manual and digital controls, this fluid bed unit enables accurate measurement of fluid velocity (0-1 m/s) and temperature (0-80C) with high resolution and rapid response time (2 seconds). Its transparent column design allows users to directly observe bed behavior during testing, enhancing understanding and precise monitoring.

Safety and Reliability Built-in

The system incorporates key safety features such as an over-pressure release valve and a thermal cut-off, protecting users and equipment during operation. These safeguards, combined with oil-free compressed air requirements and adjustable gas pressure (0.12 bar), ensure consistent and safe functioning under various operating conditions.

Designed for Laboratory Efficiency

This table-top, semi-automatic unit is optimized for laboratory use, with a compact overall height of 500 mm and a manageable weight of 35 kg. It is compatible with standard 220 V AC, 50 Hz supply and can process single specimens up to 2 kg in a 100 mm diameter bed. The included accessories simplify setup and operation for instructors, students, and technicians.

FAQs of Fluidisation And Fluid Bed Heat Transfer Unit:

Q: How does the Fluidisation and Fluid Bed Heat Transfer Unit operate?

A: The unit operates by passing oil-free compressed air through a perforated stainless steel distributor plate at the base of a borosilicate glass column filled with particles (1001000 microns). As the airflow increases, the particle bed expands and fluidises, enabling heat transfer studies. Parameters like air velocity and temperature are managed via manual or digital controls, with results displayed on a digital LCD panel.

Q: What types of particles and tests is the unit suitable for?

A: This equipment is designed to handle a wide range of sand or particulate materials with sizes from 100 to 1000 microns. It supports single specimen runs with a bed diameter of 100 mm and up to 2 kg of sample material, making it suitable for diverse chemical engineering experiments involving fluidisation and heat transfer.

Q: When should I use the over-pressure release and thermal cut-off features?

A: These built-in safety features activate automatically during abnormal operating conditions. The over-pressure valve releases excess pressure if it exceeds safe limits, while the thermal cut-off interrupts operation if temperature goes beyond the specified range, ensuring user and equipment safety at all times.

Q: Where is the Fluidisation and Fluid Bed Heat Transfer Unit most commonly used?

A: It is most commonly used in chemical engineering laboratory settings, particularly for research, teaching demonstrations, and quality control processes. The equipment is suitable for universities, research institutes, and training centers requiring practical insights into fluid bed behavior.

Q: What is the typical process for setting up this equipment?

A: Setup involves mounting the unit on a stable surface, connecting it to an oil-free compressed air supply (via the 1/2 inch BSP port), and loading the particle sample. Accessories like the rotameter and thermocouples are attached as per the instruction manual. Airflow and other parameters are adjusted using the control panel before commencing the experiment.

Q: How does using this unit benefit laboratory users?

A: Users benefit from hands-on experience with visual demonstrations of fluidisation and heat transfer, supported by precise, rapid measurements. The integrated safety and digital monitoring features ensure reliable operation, making it ideal for both instructional purposes and research applications.

Q: What maintenance is required to keep the unit functioning effectively?

A: Routine cleaning of the glass column, regular checks on the distributor plate, and ensuring the air source remains oil-free are recommended. Periodic calibration of measurement sensors (rotameter, thermocouples) and inspection of safety devices will maintain accuracy and prolong equipment lifespan.
