Expert Answer

Step 1

Let the basis of the calculation be 1 kg of the sugarcane fed to produce non-crystallized sugar.

Sugar is represented by ‘S’, Fiber is represented by ‘F’, and water is represented by ‘W’.

Assume that there is no water present in the discarded fibers from the press and in the filter cake from the filter.

The fully labelled flowchart for the given process is shown below.

Step 2

Now, apply material balance on fiber around press and label the equation as (1).

Apply material balance on sugar around press and label the equation as (2).

Apply total material balance around the press and label the equation as (3).

Step 3

Simultaneously solve equations (1), (2) a...
