The effective factors in hot air oven drying: The amount of drying depends on dryer properties including temperature,
relative humidity, air rate and food properties such as moisture and surface volume ration (Fatemi, 2003; Taherigeravand
et al, 2010).
Food particles size plays an important rule that whatever smaller, more surface and therefore more and quick
evaporation occurs. The properties of food and its components effect on heat transfer and the quality of final produc
