DE-9: Lesson 5. BASIC CONCEPTS OF MULTIPLE EFFECT .

A triple effect forward – feed evaporator is being used to evaporate a milk containing 10 % solids to a condensed milk of 50% T.S. The boiling point rise of the milk (independent of pressure) can be estimated from BPR°C = 1.78x + 6.22x 2, where x is weight fraction of T.S. in milk (K1).Saturated steam at 205.5 kPa (121.1°C saturation temperature) is being used.

Evaporator performance is rated by Lbs per hour or Kg per hour of evaporation. The greatest increase in steam economy is achieved by reusing the vaporized solvent. This is done in a Multiple Effect Evaporator by using the vapor from one effect as the heating medium for another effect in which boiling takes place at a lower temperature and pressure.

A bit more in detail . AlfaVap is a semi-welded heat exchanger, i.e. a plate pack has gasket sealed cassettes of two plates that are welded together. The fluid is concentrated in the gasketed channel while the steam passes through the welded channel. These units are ideal for when two media ha ve a very small temperature difference as it allows for use of a lower grade steam.

Mechanical recompression is not limited to single-effect evaporation. It is sometimes economical to compress vapour from the last effect of a double- or triple-effect evaporator so that the vapour can be condensed in the first-effect heat exchanger. A multiple-stage, LTV falling-film, mechanical recompression evaporator is shown above.
