quick overview :

Fluidized Bed Pilot

Teaching Objectives of

• Measurement and control of the input air temperature
• Measurement of the output air temperature
• Measurement of the product temperature
• Measurement of the differential pressure between the upstream and downstream of the distributor
• Measurement of the input flow by anemometric probe
• Product sampling
• Measurement of the input air humidity
• Measurement of the output air humidity

Functioning:

Technical Specifications of Fluidized Bed Pilot

• A fan
• A electrical heater
• The input temperature of the air flow control the heater resistance
• Safety thermostat
• A conical vat to the basis of the unit, a distributor, a product vat and an expansion area made of stainless steel AISI 304 with windows in polycarbonate.
• A filtration device at the output of the column
• An air input with coarse filter
• Mechanical locking of the product vat
• Stainless steel frame with aluminium nuts

Instrumentation:

• Fan with electronic speed driver
• Pt 100 probe for measurement of the output air temperature with digital display
• Air Humidity measurement probe with digital display and alarm threshold at the input of the fluidised bed movable before or after the resistance.
• Differential pressure measurement sensor upstream/downstream of the air distributor with digital display.
• Pt 100 probe for measurement of the product temperature with digital display and alarm threshold
• Analogical anemometer with digital display and 4-20 mA output for continuous display of the air speed.
• Battery of heating resistances mounted in a circular duct.
• Pt 100 probe with auto adaptive and programmable PID digital controller, (continuous display of the measure and the set point) for the measurement of the air input temperature.
• Air humidity measurement probe at the output with digital display.
• Temperature measurement probe at the resistance input.
• Air input filter.
• Filter at the output of the fluidised bed.
• Flexible air trucking for humid and hot air duct to outside.

Electrical cabinet including :

• The ON/OFF switch of the heating resistance.
• The temperature controller of the fluidised air input.
• The potentiometer controlling the power of the resistances,
• The displays of the Pt 100 probes, the humidity probes, the differential pressure sensor
• The potentiometer controlling the air speed.
• All transmitters have 4-20 mA output allowing an eventual data acquisition.
• Nota : This unit mustn’t be used with solvents or alcohols.
