Experimental survey on the combination of fluidized bed dryers and infrared heat source for drying of shrinking cubic-shaped bodie s

During the drying process food systems undergo several simultaneous physical and structural modifications, undersirable from the viewpoint of material end use .Cubic squash samples were utilized as the test media in the fluidized bed dryer assisted infrared heat source. The effective moisture diffusion coefficient was expressed as a function of sample temperature and average moisture content .Some correlation was developed for shrinkage and density of the drying materials .The effect of air temperature, inert amount, air velocity and IR power were investigated.
