Description: Scope of food engineering. Mass, momentum and energy balance. Dimensionless analysis. Mechanical processes: flow of liquids, shearing forces, momentum transport, laminar and turbulent flow, resistance to flow. Calculation of pressure drop. Flow through porous beds, filtration and fluidization. Buoyancy and sedimentation, classification. Centrifugal force. Mixing of liquids and powders. Heat transfer: conduction, convection and iradiation. Steady state heat transfer. Fourier's First Law. Natural and forced convection. Heat transfer coefficients. Over-all heat transfer coefficient. Unsteady state heat conduction. Sterilization. Freezing. Mass transfer processes: molecular and connective mass transfer. First and Second Fink's Law. Unsteady state mass transfer. Drying, extraction and leaching crystallization, distillation. |
