Optimization of Drying–Tempering Periods in a Paddy Rice Dryer

Paddy Drying in Mixed Adsorption Dryer With Zeolite: Drying Rate and Time Estimation

“…In this study, the moisture diffusivity was obtained in the range of 10 -12 -10 -11 m 2 .s -1 . The result is still comparable with the estimation performed in Parkash (2011) and Golmohammadi et al (2012).…”

Effect of swing temperature and alternating airflow on drying uniformity in deep-bed wheat drying

“…The plate 6 cm in height was filled with wheat. The 11 thermocouples measured the temperature at heights of 0, 6,12,18,24,30,36,42,48,54, and 60 cm. Air velocity was measured using an air flow and velocity transmitter.…”

“…The required heat during drying is changing. Some scholars have studied the effect of tempering on drying and found that tempering reduces the stress in grains and energy consumption, consequently decreasing the occurrence of grain cracks and rupture [24,[28][29][30][31].…”

“…Excessive air velocity slightly influences the drying rate, increases energy consumption and wastes high-quality energy [19]. Grains burst when the stress gradient in the grains is greater than the threshold, and this phenomenon decreases grain quality [24]. Heat and moisture transfer mechanisms in grains primarily affect grain drying dynamics.…”

Assessment of the initial moisture content on soybean drying kinetics and transport properties

“…However, drying processes at high temperatures can deteriorate the product quality by increasing temperature and moisture gradient leading to internal tensions, cracks, breakages, and fractures in the grain [16] . In this context, the intermittent operation mode of the drying process of certain products has been investigated by a significant number of authors [19,20,21,22,23,24,25,26] , aiming at minimizing the energy consumption and achieving better quality of products. Models that consider the influence of initial moisture content can improve those optimization studies.…”
