THERMODYNAMIC ANALYSIS OF FLUIDIZED BED DRYERS AGAINST THE RATE OF DRYING OF CORN

One way to extend the storage life of grain crops is drying. In Indonesia, agricultural products are usually dried by spreading agricultural produce under the sunlight or commonly called by conventional drying. In this research, corn drying is done using fluidization method. The purpose of this study is to investigate and analyze the useful energy and drying efficiency by varying temperature and air velocity in the drying process of corn. Based on SNI, the maximum moisture content of corn storage is 14%. Corn used in this research is shelled corn with maximum moisture content of 20% and tolerance ± 0,5%. The corn is dried by putting it into the dryer room of the fluidized bed tool with certain air velocities and air temperature.
Air velocity variation in use by 5 m/s, 6 m/s and 7 m/s. While the air temperature variations used amounting to 55 ° C, 60 ° C and 65 ° c. From the variation of the speed of the air and the air temperature is obtained as a result of that the higher the velocity, the faster the drying time. And the higher the temperature, the faster the drying time. The most useful energy in the air velocity 6 m/s and temperature 65 ° C is 140,629 kJ, while the least useful energy in the air velocity 6 m/s and temperature 65 ° C is. 121,547 kJ. Corn drying efficiency is the least is located on variation of air velocity 7 m/s and air temperature 55 ° C with 0,5 kg material mass is 3,278%. The highest efficiency in air velocity variations can at 5 m/s and temperature 65 ° C of 4,693 %.
