A process for concentrating orange juice takes a feed of 100 kg/h, with a sugar mass percentage of 12%, and concentrates it to 45% using the flow diagram given below.

A proportion of the feed bypasses the evaporation stage and is blended back with the concentrated product. If the sugar mass percentage leaving the evaporator is 65%, calculate all the other flow rates on the flow diagram.

 

F=100 kg/h WF = 0.123 S (1) W Evaporator B E WE=0.65; WB = 0.12 Blender (2) P Wp = 0.45
