چکیده انگلیسی
In this study, a laboratory scale continuous-band microwave dryer was fabricated and used for drying the paddy. The experiments were carried out at 3 microwave powers (90, 270, and 450â¯W), conveyor speed 0.24â¯m/min, and 3 paddy layer thicknesses (6, 12, and 18â¯mm). The penetration depth of the waves into the examined paddy was obtained equal to 12.7â¯mm at 25.46% moisture content (w.b %). The maximum energy absorption (81.46%) was obtained at 90â¯W power and 18â¯mm layer, whereas the minimum energy absorption was obtained equal to 34.90% at 6â¯mm paddy thickness and 270â¯W microwave power. The obtained results indicated that the maximum energy efficiency, the maximum thermal efficiency, the maximum drying efficiency, the minimum specific energy consumption, and the minimum seed breakage percent occurred at 90â¯W microwave power and 18â¯mm drying thickness. Therefore as a final concluding result, drying thickness of 18â¯mm and microwave power of 90â¯W was selected as the most appropriate combination for drying paddy using the continuous band microwave dryer.
