Question

write the analogy of milk:centrifugation​

Answer 1

Answer:

Dairy Processing

Clarification and Cream Separation

Centrifugation

Centrifugal separation is a process used quite often in the dairy industry. Some uses include:

clarification (removal of solid impurities from milk prior to pasteurization)

skimming (separation of cream from skim milk)

standardizing

whey separation (separation of whey cream (fat) from whey)

bactofuge treatment (separation of bacteria from milk)

quark separation (separation of quarg curd from whey)

butter oil purification (separation of serum phase from anhydrous milk fat)

Principles of Centrifugation

Centrifugation is based on Stoke's Law. The particle sedimentation velocity increases with:

increasing diameter

increasing difference in density between the two phases

decreasing viscosity of the continuous phase

If raw milk were allowed to stand, the fat globules would begin to rise to the surface in a phenomena called creaming. Raw milk in a rotating container also has centrifugal forces acting on it. This allows rapid separation of milk fat from the skim milk portion and removal of solid impurities from the milk.

hope it helps....
