  2. Separation & Mass transfer

  3. Separation - examples Filtration (microfiltration): Beer, wine, fruit juices, oil Particulate removal, clarification, microorganism removal • Membrane concentration: • Ultrafiltration • Reverse osmosis http://www.rpaulsingh.com/animated%20figures/fig11_1.htm Expression: Extract juices and oil from plant material Centrifugation: Cream separation Sifting through sieves or screens Peeling Deboning or skinning meat

  4. Stoke’s Law: separation of components differing in density 2/9 [(gravitational force)(densitysphere – densityfluid)(radiussphere)2] Terminal velocity = Viscosityfluid Cream Separation Fat globules (lower density, spheres) Skim milk (higher density, fluid)

  5. 2/9 [(gravitational force)(densitysphere – densityfluid)(radiussphere)2] Terminal velocity = Viscosityfluid Cream Separation by Centrifugation www.tetrapakprocessing.com/

  6. Mass Transfer • Mass transfer: The transfer of mass into or out of a substance • The transfer of a chemical compound from one phase to another • Examples: • Evaporation: liquid gas • Diffusion: high concentration low concentration

  7. Mass Transfer Evaporation: Drying Concentration Baking Frying Boiling Diffusion: Salt through cheese curd Smoke through meat Marinade or curing solution through meat Lye in tomato peeling Not mass transfer: Retorting Moving a fluid from one place to another
