Implementation Of DCS System and Appliance Rotary Dryer for Drying Peanuts

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 corn each experimental variable with 2 minutes time sample. Drying can be done on 80°C, 75°C, and 70°C. Largest drying flow it’s on 80°C as big as 0,152 lb / ft2 h. Meanwhile on 75°C as big as 0,101 lb / ft2 h and on 70°C as big as 0,091 lb / ft2 h. The biggest water evaporated material on 80°C as big as 3%. On temperature 75°C and 70°C that is evaporated water rate as big as 2% and 1,8%. 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 corn more dry.
