Material Balances in the Milk Fat Removal Process.

Consider $35,000$kg of whole milk containing $4\mathrm{.}0\%$ fat, while the

The rest is water and non$-$fat matter. You want to separate it in a period of $6$ hours to

obtain skim milk with $0\mathrm{.}45\%$ fat and cream with $45\%$ fat.

TIP: Take as a calculation basis $1$h of whole milk flow and

Draw a flow chart of a separation process indicating a

separation process. Do the exercise BY HAND.

$($a$)$ Calculate the input mass that occurs in one hour of the process $($R: Mass

total $=5833$kg$,$ Fat$=233$kg$)$

$($b$)$ What would be the mass of the water and the non$-$fat components? $($A: $5600$kg$).$

$($c$)$ Calculate the output mass of the process, for this, perform material balances

about fat. $($A: x $=465$kg$)$

$($d$)$ What would be the output flows of the two streams $($one of skim milk

and the other cream$)$ of the process? $($R: mcream$=465$kg$/$h$,$ mskimmilk$=5368$kg$/$h$)$
