Alfa Laval - AlfaVap system

The AlfaVap rising film evaporators use the cassette concept with the evaporator plates welded in pairs. Steam is applied as a source of heat in the welded channels of the AlfaVap evaporator while the product passes through gasketed channels. As boiling occurs inside the AlfaVap, the mixture of vapour and liquid rises to the top of the evaporator.

Wiped Film Evaporator - Concept Process Equipments

The Wiped Film Evaporator (WFE) is used for concentration, distilling, stripping, dehydration and deodorisation of products which are heat sensitive or viscous. The equipment can handle a very wide range of feed compositions ranging from 1% to over 95% concentration. WFE has several advantages as stated in the table below. The operation is continuous with [.]

Evaporators | Dairy Processing Handbook

A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.
