Design Issues: Mechanical Dryers 1. Introduction: There are three generic forms of mechanical dryer commonly found in use today. The vertical dryer, the horizontal dryer and the silo or stationary-bed dryer. These are batch dryers which naturally fit the batch pattern dictated by coffee processing, following, as it does, daily (or less frequent)


Rotary dryers are a class of dryer commonly used in industry to dry particulate solids (Keey, 1972). They are made of a long cylindrical shell that is rotated. The shell is usually slightly inclined to the horizontal to induce solids flow from one end of the dryer to the other. In direct heat rotary dryers, a hot
