Experiments were undertaken to study the relationship between the drying constant and the shrinkage constant of food products during drying. Three particular geometrical shapes of parallelepiped, cylindrical and spheres were selected from potatoes (aspect ratio = 1:1, 2:1, 3:1), cut beans (length: diameter = 1:1, 2:1, 3:1) and peas, respectively. The volumetric shrinkage behaviour and drying be...

Sago pith waste (SPW) has a great potential in becoming numerous kinds of reusable products as it high level starch content after went through drying process. Without proper treatment the disposal SPW could cause serious environmental problem. The process using fluidized bed dryer (FBD) was found to be more effective than other methods. Thus, this study analyzed computational fluid dynamics (CF...

Highlights Uneven drying is an inevitable drawback when using heat pump-based deep-bed dryers in commercial industries. Understanding the behavior of important to optimize technology. COMSOL Multiphysics a very helpful tool as it can be used predict behavior. Abstract. Heat pump are widely agricultural products because its capability at comparatively lower temperatures scale. However, (HPD) lea...
