Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : In centrifugal cream separator, cream outlet is at higher level than the skim milk outlet.
Reason (R) : Specific gravity of milk fat is higher than the skim milk.
In light of the above statements, choose the correct answer from the options given below.
EXPLANATION
Fat-Rich, Concentrated & Dried Dairy Products
- Assertion (A) is True: In a centrifugal disc-bowl cream separator, the less dense cream migrates towards the central axis of rotation and discharges through the inner/upper cream outlet, whereas skim milk discharges through the outer/lower nozzle.
- Reason (R) is False: The specific gravity of milk fat is $0.93$, which is lower than the specific gravity of skim milk ($1.036$). Because milk fat is lighter, centrifugal force drives denser skim milk to the bowl periphery while fat globules displace inwards towards the center.
- Conclusion: (A) is true, but (R) is false.
Correct option: (3) (A) is true but (R) is false
