Comparison of the Effects of Fixed Bed and Fluidized Bed Drying on Physical Property Changes of Spherical Food Material Using Peas as a Model Material
نویسنده
چکیده
Changes in the physical properties (such as particle density, bulk density of the bed, shrinkage and bed porosity of fresh green peas particulates were compared at 50 o C, during fluidized bed drying and fixed bed drying. Empirical relationships of the following nature were developed for the changes in shrinkage [VR = A + B MR], particle density [ρ p = A + B MR + C exp (-DMR)], and bulk density [ρ b = A + B MR + C MR2] with moisture content for both fixed bed drying and fluidized bed drying and compared.
