Abstract

Solid drayed meaning water separate from solid substance. One of drying equipment is rotary dryer, it consist of one rotary cylinder, horizontal, or rather oblique downwards with DCS (Distributed Control System), in order to control manufacturing process continually or batch-oriented. In this case using 5 kg grain each experimental variable with 3 minutes time sample. Drying can be done on 80°C, 70°C, and 60°C. Largest drying flow it’s on 80°C as big as 0,359 lb / ft2 h. Meanwhile on 70°C as big as 0,214 lb / ft2 h and on 60°C as big as 0,0501 lb / ft2 h. The biggest water evaporated material on 80°C as big as 5,92%. On temperature 70°C and 60°C that is evaporated water rate as big as 3,7% and 0,08%. More drying time it takes, more evaporated water loss and also the drying flow. Drying flow straight equal with temperature and equal with evaporated H2O. As a result, the best operational condition is on temperature 80°C because it’s the highest evaporated water and also the larger drying flow that can make the grain more dry.
