In a process for concentrating 1000 kg of freshly extracted orange juice containing 12.5 wt % solids, the juice is strained, yielding 800 kg of strained juice and 200 kg of pulpy juice. The strained juice is concentrated in a vacuum evaporator to give an evaporated juice of 58% solids. The 200 kg of pulpy juice is bypassed around the evaporator and mixed with the evaporated juice in a mixer to improve the flavour. This final concentrated juice contains 42 wt % solids. Calculate i. the concentration of solids in the strained juice. ii. the mass in kilograms of final concentrated juice. iii. the concentration of solids in the pulpy juice bypassed.
