Strawberries contain about 15 wt% solids and 85 wt%
water. To make strawberry jam, crushed
strawberries and sugar are mixed in a 45:55 mass ratio, and the
mixture is heated to evaporate water until
the residue contains one-third water by mass. Draw and label a
flowchart of this process and calculate
how many pounds of strawberries are needed to make 500 pounds of
jam.

Strawberries contain about 20 wt% solids and 80 wt% water. To make strawberry jam, crushed strawberries and sugar are mixed in 0.55 mass ratio, and the mixture is heated to evaporate water until the residue (the strawberry jam) contains 1/3 water by mass. Calculate how many pounds of strawberries are needed to make a pound of jam.

4.14. Strawberries contain about 15 wt% solids and 85 wt% water. To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass. (a) Draw and label a flowchart of this process. (b) Do the degree-of-freedom analysis and show that the system has zero degrees of freedom (i.e., the number of unknown process variables equals the number of equations relating them). If you...

1. The garden strawberry is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries. It is cultivated worldwide for its fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantiies, either fresh or in prepared foods such as preserves, juice, jam, pies, ice creams, milkshakes, and chocolates. To make strawberry jam, strawberries containing 15 wt% solids and 85 wt% water are crushed....

% water, the rest of the liquor stream is solids. Beet molasses contains 50 wt% sucrose, 1.0 wt% dextrose, and 18 wt% water, the rest of the molasses stream contains solid. Beet molasses is mixed with corn-steep liquor and water in a mixing tank to produce a dilute sugar mixture. The exit stream contains 2.0 wt%, dextrose and 12.6 wt% sucrose and is ready to be fed into a fermentation unit. See Figure 3.26. (Adapted from Doran PM, Bioprocess Engineering...

Fresh orange juice contains 12.0 wt% solid and the water, and concentrated orange juice contain 42.0 wt% solids. Initially a single evaporation process was used for the concentration, but volatile constituents of the juice escaped with the water, leaving the concentrate with a flat taste. The current process overcomes this problem by bypassing the evaporator with a fraction of the fresh juice. The juice that enters the evaporator is concentrated to 58 wt% solids, and the evaporator product stream is...
