Chemistry Research Task - Dairy Milk Processing

Whole draw is clarified, dis arrayed for the lower luscious draw, pasteurized, and homogenised. The fat left wing from the withdrawal is apply for cream, unlesster, sweetened condensed take out, sorbet cream and another(prenominal) take out products. The primary objective of process milk is to deal the milk?s shelf life and elapse 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 round 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 due(p) (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 set-apart by a 0.4 to 2.0 mm gap or insulation channel. Milk is introdu ced at the outer edge of the disc survey. The stack of discs has vertically aligned distri simplyion holes into which the milk is introduced. (See schematic on next page). Under the influence of centrifugal force, the fat globules (cream), which be 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 mainly to separate liquids from solids in a way that is similar to, but faster than, filtration.

Centrifuge separation works generally due to differenc! e 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 precedent 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 clothe forth. Well done.
