This research aims to design and build to test the performance of a fluid bed drying, wind, the use of the inverter to control the ripple for the sunflower seeds drying room with rectangular cross-sectional size 0.15 "x" using the 1.5 m 0.15 m 2 high heater size 10.7 kW controlled by them neck system.Your blower motor 0.5 hp size used in the experiments, the drying temperature of 170° C and under a period of wind speed 1.5 m/s low-side. Period of wind speed 3 m/s for side brings tested performance drying machine by performing the drying air is 100% back, and select the terms of return of the air. 3. the value of 25, 50 and 75% in order to bring to trial with the best conditions and the weather is back 100% found that the time period and the wind speed high side 2.5 s and a duration, low-side, wind speed 1 s is the best conditions. With power consumption specifications 3.394 kWh/kg ± 0.048 while drying chaliang precious nearby reduced conditions other. Air rate results returned found that energy consumption values drop when the rate of return air increasing.
