Determination of Thermal Conductivity of Aloe in the Cooling and Thawing Process

Abstract : In this study, thermal conductivity of aloe was determined in the cooling process from 20°C to -11°C, and in the thawing process from -11°C to 20°C using the tiny thermal probe method. The tiny thermal probe measurement system had the advantages of high accuracy, short test time, low temperature rise and little water removal and was found to give accurate and consistent experimental results. The results showed that the thermal conductivities increased with temperature over the freezing point. The thermal conductivities rapidly increased below the freezing point and it increased with the temperature decreasing. The thermal conductivities decreased with temperature below the thaw point. The thermal conductivities rapidly decreased over the thaw point and it decreased with temperature. The thermal conductivity of aloe in the cooling process was greater than that in the thawing process at the same temperature.
