5. Bypass Stream – Orange Juice Concentration. Fresh orange juice typically consists of about 12 wt% dissolved solids, largely sugars, in water. In order to reduce shipping costs, the juice is often concentrated prior to shipping and then reconstituted at the destination. Some loss of the flavonoids and thermally sensitive volatile components occur in this step, so a widely accepted approach is to somewhat concentrate the juice and then add a small amount of fresh juice (called a cutback) to the concentrate to produce a product of improved flavor and aroma. Suppose that 10 wt% of the feed to such a process is used as cutback, and the evaporator is used to produce an outlet concentrate of 80 wt% dissolved solids. The process feed rate is 10,000 Ibm/hr fresh juice., a) Draw a diagram, and label key components Calculate the rate at which water must be evaporated and the composition b) of the final product

5. Bypass Stream – Orange Juice Concentration. Fresh orange juice typically consists of
about 12 wt% dissolved solids, largely sugars, in water. In order to reduce shipping
costs, the juice is often concentrated prior to shipping and then reconstituted at the
destination. Some loss of the flavonoids and thermally sensitive volatile components
occur in this step, so a widely accepted approach is to somewhat concentrate the juice
and then add a small amount of fresh juice (called a cutback) to the concentrate to
produce a product of improved flavor and aroma. Suppose that 10 wt% of the feed to
such a process is used as cutback, and the evaporator is used to produce an outlet
concentrate of 80 wt% dissolved solids. The process feed rate is 10,000 Ibm/hr fresh
juice.,
a)
Draw a diagram, and label key components
Calculate the rate at which water must be evaporated and the composition
b)
of the final product
