Technical Abstract: The rotary drum is widely used by industry to carry out a wide variety of process applications. This is certainly not different in the food industry where it is employed for several food processing operations. Applications such as food powder mixing and de-mixing, simple heating or cooling of grains, evaporative drying, baking of food and food products all using the rotating drum processor are common in the industry. The focus of this article is to present the features of the rotary drum as a food processor by providing a quantitative description of the transverse bed motion and segregation of bed materials and the resultant effect of these phenomena on the bed heat transfer during food processing applications such as drying, heating or cooling, roasting, bloating and even cooking.
