چکیده:

Drying behavior of green peas is investigated in a pilot scaled fluidized bed dryer with inert particles assisted by an infrared heating source. The variations of shrinkage and moisture diffusivity with temperature and moisture content were investigated. The variations of shrinkage are a function of moisture content. It was found that shrinkage was a function of moisture content and moisture diffusivity was also dependent on temperature. The values of moisture diffusivity which obtained are in the range of 5E-10 to 30E-10. Some correlations were proposed for these properties.
