Chemistry Research Task - Dairy Milk Processing

Whole draw is clarified, dis arrayed for the lower gamy take out, pasteurized, and homogenised. The fat left wing from the withdrawal is apply for cream, unlesster, sweetened condensed take out, crosspatch cream and another(prenominal) draw products. The primary objective of touch milk is to deal the milk?s shelf life and discriminate 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 farm processing to remove the spherical 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 repayable (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 uninvolved by a 0.4 to 2.0 mm gap or separation chann el. Milk is introduced at the outer edge of the disc throne. The stack of discs has vertically aligned distri exception holes into which the milk is introduced. (See schematic on next page). Under the influence of centrifugal force, the fat globules (cream), which atomic number 18 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 main to separate liquids from solids in a way that is similar to, but faster than, filtration.

Centri! fuge separation 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 prior to pasteurization), skimming (separation... This is an impressive essay. It tries to discuss a rather scientific 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 neaten forth. Well done.
