Evaporation and bypass in orange juice concentration.
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 stained juice and 200 kg of pulpy juice.
The strained 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 favor.
This final concentrated juice contains 42 wt% solids.
Calculate the concentration of solids in the strained juice, the kg of final concentrated juice , and the concentration of solids in the pulpy juice bypassed
Hint : first, make a total balance and then a solids balance on the overall process.
Next, make a balance on the evaporator.
Finally, make a balance on the mixer.
