Circulation evaporator - Wikipedia

In this design, the liquid enters the third effect at a low temperature and moves to the second stream in which concentration is increased due to the previous evaporation effect. Finally, the optimum product concentration is achieved in the first effect.

Evaporator Handbook - APV Hemisan

Low surface areas together with low HTC's generally limit the evaporation capacity of such a system. Heat transfer is improved by agitation within the vessel. In many cases, large temperature differences cannot be used for fear of rapid fouling of the heat transfer surface. Relatively low evaporation capacities, therefore, limit its use .

Plate type evaporators. Rising film evaporation in plate type evaporators is a feasible option for media having low tendency to fouling. Due to the minimized hold-up in this type of evaporator it is widely used for concentration of temperature-sensitive products and offers further advantages due to its compact design and low investment costs.

Evaporation - Lenntech

For single effect evaporator, the steam economy is ca. 0.8 (<1), which translates to 0.8 tons of steam needed to evaporate 1 ton of water. So as to decrease the evaporator steam economy, the multiple-effect design uses the exhaust vapors from the product to heat the downstream evaporation effect and reduce the steam consumption.
