The purpose of this project is to Design, build and test the control weather conditions of drying for banana By the control weather conditions can adjust the temperature. The speed and the relative humidity of the air. By testing both baked banana ball with the air temperature variation 60 °, and C 70 ° C 80 ° C speed and 3.6m / s 9.7M / s with increasing the moisture from the original one. Banana, initial moisture 281.78 edge 23.36%dry basis drying until the final moisture content of 41.19 edge 3.57%dry basis found that temperature increase. The spent drying drops all conditions.
The study found that at the speed 9.7M / s when air temperature rise result. The drying rate increases. The rate of power consumption is more and more. When compared with the speed 3.6m / s to ticks that the rate of energy consumption is less than The relative humidity is cost reduction was slower. Take a long time and speed 9.7M / s and from the comparison of drying rate at 70 ° C ที่ความเร็ว 9.7 M / S. Spray the specific energy is minimal in 0.62 edge 0.42 kWh.
