Cooling crystallisation

Crystallisation enables dissolved substances from solutions to be transformed into a solid and separated. This unit demonstrates the process within a fluidised bed for clear visualization of crystal growth.

• crystallisation from solutions in fluidised bed
• stirred tank for preparation of a saturated solution
• circuit for undersaturated solution with tank, 2 heat exchangers for heating and pump
• bypass for oversaturated solution with crystallisation cell and 2 heat exchangers for cooling
• removable and fillable crystallisation cell, PMMA
• heating circuit with pump, tank, regulated heater
• adjustment of flow rate in bypass using valves
• measurement and control of temperatures in stirred tank, tank for undersaturated solution and in crystallisation cell
