PROBLEM 2 To prepare a delicious banana milk on an industrial scale, there is an experimental process that consists of seven unit operations. A stream of banana (whose components are fruit, peel, and moisture) is fed to a peeler, where 99.9% of the peel is removed. This stream should become pulp, so it is mixed with an additive Q to avoid pulp oxidation. This mixture is then sent to an extruder press wherein a stream of a 50:50 mixture of additives Q and R is added. The resulting flow of 30 kg/h has a composition of 2% additive R and 5% additive Q. This flow is then fed to an agitated mixer. To the same mixer is fed a dairy stream of 250 kg/h that contains 70% milk (the rest is water) and a sweet aqueous stream that contains 30% sugar. For each 25 kg/h of dairy flow, 2 kg/h of the sweet flow is fed. The stream that leaves the agitated mixer has 5% fruit and 0.005% peel and enters a series of two thermal processes in which each operation allows 5% of the water and 2% of the milk to evaporate. The resulting flow of the heat treatment (hot banana milk) finally joins another mixer, where the flavoring G is added. The final banana milk contains 30% water. 1. Draw a complete diagram of the process. Label all streams properly. 2. Calculate: a. the composition (in %) and flow (kg/h) of the initial stream of bananas; b. the annual flow of peels (in ton/yr) that are separated in the process, assuming 300 days of 24/7 operation; c. the mass lost (in kg/h) during the thermal process; and d. the composition (in %) and flow (kg/h) of the final product stream. 3. In the case where the density of the final product is 1.3 g/mL, calculate how many 0.2 L packages of banana milk are produced per month, assuming 30 days of 24/7 operation.
