Most of the drying takes place while the material falls through the air blast. Using very hot air or combustion gases, rotary dryers can also function as roasters for nuts, sesame seeds, and cocoa beans. A detailed method for the design of rotary dryers, based on a heat exchange approach has been described by Nonhebel (1971)

May 16, 2020 The rotary dryer’s drum is a slightly angled and rotatable cylinder with wet material entering from one end up and dry material collecting from the other end down. Hot air enters at the inlet or outlet end and exits at the top of the other end. The barrel is equipped with a forward-running plate, which makes the material to be continuously run up and down in the process of turning the barrel
Apr 01, 2001 Abstract: A 3-yr study was conducted to assess cranberry bean susceptibility to mechanical weeding using a rotary hoe at preemergence, hook, cotyledon, unifoliate, and first to fourth trifoliate stages of bean development and at different combinations of stages. The experiment was conducted in a weed-free environment. Cultivation with the rotary hoe reduced bean yield only for the
