This study aims to test the performance of the spinner rotary dryer machine as an innovation combining the spinner and rotary dryer systems to increase drying efficiency on a household scale. The machine is designed with a 40 liter cylinder capacity, using a 0.25 HP electric motor and a used oil-fueled heating system that is flowed using a blower into a rotating drum. Tests were carried out using corn media with variations in drum rotation (13, 18, 23 RPM) and wind speed (7.4; 9.3; 11.4 m/s). The results showed that the best combination was at 23 RPM and 11.4 m/s, resulting in a reduction in air content of up to 30.1%, a drying efficiency of 64.32%, and a drying rate of 2.01 kg/minute. The higher the air velocity and drum rotation speed, the more optimal the heat transfer and even distribution of the material, thus increasing drying effectiveness.
