Operating a Fluid Bed Drier
Objectives of Experiment and Learning Outcomes
Operate a fluidized bed drier.
Describe safe laboratory operations.
Determine the heat transfer coefficients in a fluidized bed dryer.
Describe the analysis of drying curves for various food matrices by using fluidized bad dryer.
Fluidized bed drying of the food and food products is one of the most efficient drying methods, which is finding ever-growing applications in diverse industries, especially in the pharmaceutical and the food industries. One of the promising drying processes is drying of food product in a fluidized bed, due to better heat and mass transfer, shorter drying time, better quality of products obtained and shorter reconstitution time. Fluid Bed Dryers are used to dry loose granular solids and are characterized by a large exchange area between the particles and the gas, and thus, by high heat and mass transfer coefficients. Hence, they provide uniform wet masses for drying, high drying...
