Instead of tube and shell heat exchangers, framed plates can be used as an heating surface. These plate assemblies are similar to plate heat exchangers, but are equipped with large passages for the vapor flow. In these units a product plate and a steam plate are connected alternately. The product passage is designed for even distribution of liquid on the plate surfaces and low pressure drop in the vapor phase.

In multiple-effect evaporators with TVR, the heating medium in the first effect is the product vapor from one of the associated effects, compressed to a higher temperature level by means of a steam ejector (TVR). The heating medium in any subsequent effect is the vapor generated in the previous effect. Vapor from the final effect is condensed with incoming product, supplemented by cooling water. The condensate is high quality water that can be used as boiler feedwater, CIP liquid, for preheating the drying air of an associated spray dryer, or any other application.
