“…Hossain et al [17] found isosteric heat to be a power function of equilibrium moisture content for pineapple. Although an equation for isosteric heat of wheat grain and some common seeds together with the parameters has been reported, [20,21] negligible information is available on the isosteric heat of hybrid rice kernels. Therefore, this study was carried out to estimate this important thermodynamic property together with the parameters for different forms of hybrid rice kernels.…”

Hygroscopy of hybrid rice affects storage, handling, and processing. The thermodynamic relationship upon which the estimate of isosteric heat is based is the Clausius-Clayperon equation. The net isosteric heat of sorption was determined from the slope of the ln(rh) versus 1/T lines at a constant moisture content. Net isosteric heat of desorption was found higher than that for the adsorption within a moisture content range of 12-20% for all of the rice kernels. The net isosteric heats of desorption and adsorption were higher for hybrid rough rice kernels followed by brown rice and milled rice kernels, respectively. An empirical equation was fitted to describe the net isosteric heats of hybrid rice kernels as a function of moisture content and was found adequate to predict the net isosteric heats. The intercept K was also found to be a function of moisture content and the model predicted the K value well (r 2 = 0.85 for adsorption and r 2 = 0.92 for desorption). This set of two equations would be useful in the simulation of hybrid rice during storage.

“…Therefore, for a specific condition of a stored product including its type, dry-bulb temperature and moisture Wet-bulb b i o s y s t e m s e n g i n e e r i n g 1 3 9 ( 2 0 1 5 ) 1 2 8 e1 3 5 content, there is a value of equilibrium relative humidity (RH) of intergranular air. There are several sorption models that can be applied to calculate equilibrium relative humidity values from stored grain conditions, including Hunter's isostere equation (Hunter, 1987), Modified Henderson equation (ASAE, 1998), Modified Oswin equation (ASAE, 1998), and Chung-Pfost model (Chung & Pfost, 1967). Using the iterative procedure of Brent (1973), the dry-bulb temperature at which the constant enthalpy line intersects the airewater saturation curve was obtained.…”
