Edible oil was an important material daily diet and modern food industry indispensable, with a high nutritional value. Oil refining process degumming, deacidification, bleaching, deodorization, dewaxing ( fat) , and other process equipment needed to be processed in accordance with the selection of equipment thermal conductivity grease. The experimental measurement principle based on the transient plane source ( TPS ) , using Hot Disk thermal constants analyzer, sunflower oil and corn germ oil at different heating power, thermal conductivity measuring time and temperature were tested, and the effect of the optimal experimental parameters, programs, research heating power, the measurement time and temperature on the thermal conductivity was studied.
