FORCED CIRCULATION EVAPORATOR

This is ideal for concentration of high viscous material and products with higher solids. This is also used as evaporative crystallizer. Some times these are used in series with falling film evaporators as finishing effect for achieving higher concentration. In this type of evaporator, liquid is pumped through heat exchanger tubes at high velocity (1.5-4.0 m/s) avoiding precipitation and creating high turbulence; liquid is then passed through vapour separator for separation of vapour and finally condensing the vapour in the condenser. Concentrated liquid is continuously discharged from bottom of vapour separator.

Applications

• Brine evaporation (Vacuum Salt processing)
• Effluent concentration with High suspended solid
• Fruits Pulp
• Concentration Tomato Paste Sodium Sulphate Crystallization
