WebA 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. WebFig.1: Single effect evaporator In order to increase the economy we may consider the arrangement of the two evaporators as shown in the fig.2. The figure 2 shows that the two evaporators are connected in series. The saturated vapor coming out from the evaporator-1 is used as steam in the second evaporator.
