Determining the Rate of Drying Soybean on the Rotary Dryer

Abstract

Drying is processing expenditure of water from material by using hot energy so that level of water content from the material declines. Draying process usually is accompanied with evaporation process of water which there is in material. Soybean ( Glycine max/white soybean, Glycine soja/black soybean ) be one of legums crop becoming base goods many foods from East Asia like ketchup, knew, and tempe. Soybean is vegetable protein primary source and world vegetable oil. From nutrition content, this soybean is food which many its the benefits, like source of protein, fat, vitamin, mineral, also is best fibre. In this research applied dryer in the form of rotary dryer to dry soybean. Rotary dryer consisted of shell is in the form of horizontal cylinder attached at one particular roll pad, so that this cylinder hinged and its(the position a few forming angle of inclination. Feed enterred at high tip from cylinder, and will go out as dry product at other tip. As heater can be applied hot weather or combustion result flue gas stilling has high temperature. In the drying of soybean applies inferential dryer rotary that temperature excelsior used the drying speed excelsior and temperature excelsior applied hence would be ever greater also water content evaporated in soybean.
