Pineapple contains about 20 wt% solid and the balance water. To make pineapple jam, crush

pineapple and sugar are mixed in a mass ratio of 1:5. The mixture is heated to evaporate water until the produced jam contains 30 wt% water.

1) Draw and label a complete flow chart of the process.

2) Express degree of freedom (DOF) of the overall process (not the individual unit operation).

3) Give your comment on the DOF value.

The system is exactly, specified problem and the values of all the unknows will be determined unkowns will have a unique value.

Explanation:

given informtion:

pineapple:

water = 80 % = 0.8

solids = 20% = 0.2

pineapple : sugar = 1:5

jam:

water = 30% = 0.3

solids and sugar = 70%

basis: 1 kg pineapple

therefore, sugar = 5 kg

the process flow sheet is as:

As per the figures shown in the attached file, DOF = 0, thus the system is exactly, specified problem and the values of all the unknows will be determined unkowns will have a unique value.
