The effect of drying air temperature on the mechanical properties corn kernels was investigated. Corn dried at temperatures 40, 50, 60 and 70°C flow rate 1.8 kg/min in a convective dryer. were then loaded uniaxially material testing machine loading 3 mm/min, up to rupture point. An increase from 40 increased kernel deformation point by an average 12%. Moreover, values force, stress, toughness, modulus elasticity decreased 21, 26, 36, 38%, respectively.
In this study, a portable optical instrument was designed and developed for real-time nondestructive determination of fruit ripeness. A prototype the using inexpensive parts calibrated apple ripeness detection based on moisture content, soluble solids pH, firmness. An array six point sources (light-emitting diodes (LEDs) that emit light at 520-, 670-, 920-, 970-, 1050-, 1320-nm wavelengths) were selected visible/near infrarred (Vis/NIR) spectral analysis samples. The equipped with fibers,...
This article reports the incorporation of a rotary desiccant wheel unit into an air recirculated convective dryer and testing it by drying corn kernels. Experiments were conducted with without at temperatures 50, 60, 70°C flow rates 1, 1.4, 1.8 kg/min. The effect temperature, rate, on time, energy consumption, specific moisture extraction rate investigated. Statistical analysis data showed that temperature had significant effects time was significant. Results indicated is economical useful...
در این تحقیق خشک شدن ذرت یک کن هوای داغ دماهای 50 ، 60 و 70 درجه سلسیوس سه دبی جابه جایی گرم 1، 4/1، 8/1 کیلوگرم بر دقیقه به صورت لایه نازک پیوسته بررسی شد. آزمایش ها قالب طرح کاملا تصادفی گرفت. تأثیر دما هوا پارامتر زمان آهنگ شدن، ضرایب نفوذ رطوبت انرژی فعال سازی نتایج دست آمده نشان داد که فاکتورهای سرعت جابهجایی فرآیند محصول معنی دار می باشد. تیمارهای طور متوسط افزایش از به 7/31% تغییر 1 27% را کاهش داد. ضریب ﻣﺆثر فعال-سازی به ترتیب بین 11-10×47258/3 تا 11-10×34352/7 مترمربع ثانیه...
