Chemistry Research Task - Dairy Milk Processing

Whole draw is clarified, dis arrayed for the lower ample take out, pasteurized, and homogenised. The fat left wing from the withdrawal is apply for cream, unlesster, sweetened condensed draw, looking glass cream and another(prenominal) take out products. The primary objective of affect milk is to deal the milk?s shelf life and go through pathogens that could be harmful. Heat treatment is the most common processing proficiency and pasteurisation destroys the most heat resistant pathogen, M. tuberculosis. Centrifuges be used in dairy processing to remove the global milk fat from the serum, the skim milk. This normally takes place at a temperature between 50-60ºC. The globular milk fat in this wooing is the resi over callable (left in the centrifuge), and the filtrate is the skim milk (passes off of the centrifuge). The centrifuge consists of up to 120 discs messed together at a 45 to 60 degree angle and divide by a 0.4 to 2.0 mm gap or musical interval channel. M ilk is introduced at the outer edge of the disc plentifulness. The stack of discs has vertically aligned distri thoion holes into which the milk is introduced. (See schematic on next page). Under the influence of centrifugal force, the fat globules (cream), which argon less dense than the skim milk, move inwards by dint of the separation channels toward the central axis of the centrifuge. The skim milk moves outwards and leaves through a separate outlet in the machine. Centrifugation is based on Stokes Law. Centrifuge separation is used in the first place to separate liquids from solids in a way that is similar to, but faster than, filtration.

Centrifuge s! eparation works generally due to difference in particle size, density, viscosity, and state of matter (solid, liquid, or gas). Centrifugal separation is often used in the dairy industry. Some uses include clarification (removal of solid impurities from milk antecedent to pasteurization), skimming (separation... This is an impressive essay. It tries to discuss a rather proficient process, without the aid of diagrams or other visual aids, and it succeeds. I am impressed at the amount of information that was conveyed, and the clarity with which it is fit out forth. Well done.
