Specific Heat of Soybean

Abstract

The specific heat of soybean, determined by the method of mixtures, exhibited linear positive correlation with moisture content in the moisture range from 8.1 to 25% d.b. for the mean temperature of 315 K and can be expressed in the form as Cp=1.444 (1 + 4.06 × 10−2M). The specific heat values increased from 1.926 to 2.912 kj/kg‐K in the given moisture range. Further, the specific heat values obtained in the present study when compared with the values predicted by the other empirical methods indicated the close approximation of observed and estimated values.

Computer simulation of radio frequency selective heating of insects in soybeans

“…The bulk density of dry soybeans at room temperature was measured by a basic volume method using a 30 Â 22 Â 6 cm 3 plastic rectangular container and obtained to be 739 ± 3 kg/m 3 over three replicates. Thermal properties (thermal conductivity and specific heat) at a bulk density of 739 kg/m 3 were calculated by Deshpande's regression equations [33,34]. Thermal properties of the insect larvae were reported by Ben-Lalli et al and Sahin and Sumnu with different measured components [32,35].…”

Computational modelling of the impact of polystyrene containers on radio frequency heating uniformity improvement for dried soybeans

“…5b) of soybeans, which increased with increasing temperature at moisture contents of 4.64 and 7.86% w.b. (Deshpande & Bal, 1999;Deshpande et al, 1996). These data were subjected to linear regression analysis (R 2 N 0.99) at temperature range of 20-80°C for using these properties in the simulation model.…”

“…Bulk density of soybeans was assumed as constant and temperature independent during the simulated process. The bulk thermal conductivity and heat capacity values of soybeans were measured and reported by Deshpande, Bal, and Ojha (1996) and Deshpande and Bal (1999). Dielectric properties of soybeans at its particle density and 27 MHz were obtained from Guo et al (2010) in the range of 20-80°C.…”

Simulation and prediction of radio frequency heating in dry soybeans

“…For density, heat capacity and thermal conductivity of dry soybeans, three wellknown equations were used as a function of moisture content (w.b.) of dry soybeans by following regression formula (Deshpande & Bal, 1999;Deshpande, Bal, & Ojha, 1993:…”
