Mechanical pan circulators (MPC) is employed to move a fluid throughout a system. It is used to maintain a consistent temperature within the system, and the fluid is typically a liquid or gas. A pump circulates the fluid, and the thermostat governs the pump. In order to maintain the proper temperature, the thermostat regulates the pump's on and off times. The efficiency of the crystallisation process is increased in the sugar business by the use of mechanical pan circulators (MPC). It boosts pan yield while reducing boiling time and sugar colour. This device is utilised in vacuum pans to produce better and stronger massecuite circulation, which improves heat transfer and shortens the boiling time.
