fruit juice at 25 ° C containing 5% total solids concentrated via a single effect evaporator. The evaporator is operated in a vacuum at an evaporation temperature of 80 ° C, and 90% quality steam is supplied at 169.06 kPa. The desired concentration of the final product is 40% total solids. The rate of concentrated product leaving the evaporator is 2500 kg / hour. The specific heat of fruit juice is 4.05 kJ / (kg ° C), and the concentrated product is 3,175 kJ / (kg ° C). Calculate the required steam rate and Steam economy if the condensate temperature is released at 90 ° C
