The single screw press was used to preheat the oil by auxiliary heating of the press barrel by a heating device, and the temperature on the outer wall of the press barrel was measured by an infrared thermometer. Based on the inverse problem theory of heat conduction, the temperature distribution of the inner and outer wall of the press barrel was obtained through ANSYS Workbench. Comparing the measured temperature on the outer wall of the press barrel with the simulated temperature, the error range was between -2.023% and 6.274%, indicating that the temperature distribution on the inner and outer wall of the press barrel could be predicted by ANSYS Workbench.
