Abstract

Pressing is a common method to extract oil from oilseeds. In this method, no additives are added to the oil. The oil obtained using this method has impurities that make the color cloudy and reduce its shelf life. So, it is necessary to separate these impurities to increase the quality. In order to separate impurities from oil, a set including: pump, filter, flow control valve, pressure control valve and tank was designed and built. In this research, sesame oil was purified using a linen filter, and the compressibility of the cake and the effect of temperature and pressure on the efficiency of the filter were investigated. The compressibility coefficient for the cake in the linen filter was equal to 0.13, which shows that the porosity of the cake is relatively low. Variance analysis of linen filter efficiency data showed that temperature and pressure have no significant effect on the separation efficiency of this filter and the average separation efficiency of this filter was 76%, also temperature and pressure in the selected ranges did not affect the filter separation efficiency.
