A method to predict the temperature distribution on the inner surface of spiral oil press

【Objective】To predict the temperature distribution on the inner surface of the spiral oil press. 【Method】The finite element method was used to analyze the squeezing chamber’s thermal. The objective function of the squeezing chamber’s outside surface’s temperature distribution was established and a method was put forward to solve the temperature distribution of the squeezing chamber’s inner surface. 【Result and conclusion】The effective of this method was varifed. Analysis results show that this method can provide the theoretical basis for the development of a squeezing chamber and the design of high performance oil press.
