Effect of cooking and drying on the thermal conductivity of rice

Testing of thermal properties of foods is essential for operation and control of food processing plants. In this paper, the thermal conductivity of rice and the drying of cooked rice is measured. These measurements are determined using a transient line source over a temperature range of 50-70°C, a moisture content range of 10-70%, packing density range of 500-850 Kg/M3Author(s):

Thermal properties of green alumina porcelain

The thermal properties, as well as bulk density, and mass loss of alumina porcelain were determined as a function of firing temperature. It was found that after sintering at 1320 ºC, the thermal conductivity and thermal diffusivity increased by ~700% and ~400%, respectively....

Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes

Polymeric tannin/furanic foams fortified with polyurethane (PUR) and 4,4’ diphenylmethane diisocyanate (pMDI) were prepared. The thermo-physical and mechanical properties of the produced foams were investigated experimentally.  It was found that since there were a number of active isocyanate groups on the PUR that was used, there was no difference in adding PUR or pMDI to the foams, and so only the results for pMDI were presented. It was found that ...

Structure and properties of rigid foams derived from quebracho tannin

Rigid foams were prepared using quebracho tannins and their physical and thermal properties were determined experimentally. These properties were then compared to those of rigid foams derived from mimosa tannins and pine tannins to determine if the nature of the flavonoid affects the properties of the foams. It was found that the preparation of the quebracho tannin-based foams involved the same formulation as that of mimosa tannin-based foams, whereas the ...

Experimental determination and fractal modeling of the effective thermal conductivity of autoclaved aerated concrete: Effects of moisture content

Autoclaved aerated concrete was studied because it has potential to be used in the design of energy-efficient buildings. Three different samples were tested, each with a unique density. Of particular interest to this work was the thermal conductivity of the samples, as this material would be used as a thermally insulating concrete. The thermal conductivities were measured at various percentages of moisture content, and it was found that increasing moisture ...
