Thermistor for measuring thermophysical properties of carrot and potato

Measurement of thermophysical parameters is very important for mathematical simulation calculation in the processing and storage of agricultural products. A method using a tiny thermistor as heat transfer model was developed to measure thermophysical properties (thermal conductivity and thermal diffusivity) of three standand samples(ethanol, ethylene alcohol, solution of calcium chloride). Results showed that there was no significant difference between measurement and recommendation; results of thermal conductivity from thermistor method and heat probe method for carrot and potato samples showed no significant difference; results of thermal diffusivity between thermistor method and calculation for carrot and potato samples showed no significant difference. Thermistor can be used to determine thermophysical property of agricultural products.
