The Study of Grains Drying in Tapered Fluidized Bed

Drying is essentially a process of simultaneous heat and mass transfer. In most drying operations, Water is the liquid evaporated, and air is the drying medium. Heat, necessary for evaporation, is supplied to the particles of the material and moisture vapor, evaporated liquid, is removed from the material into the drying medium. The objective of this paper is to describe the development of tapered fluidized bed wheat drying including the mathematical model used. Important experimental results from both laboratory-scale and commercial dryers will be presented
