摘要：Pressing is one of the important steps in the oil production by using a mechanical method.Optimizationin the oil pressing need is conducted in order to obtain high yield and quality of the oil.A suitable temperatureand pressure in the oil pressing will give an optimum condition for the operation causing oil flows easier.Theobjectives of this research were to get conditions of temperature and pressure in rubber seed pressing in orderto obtain high yield and physico-chemical properties of rubber seed oil for the chamois tanning.The sun-driedseeds were dried in an oven at temperature of 70 oC for one hour,and then were pressed by using a hydraulicpressing at temperatures of 55 oC,65 oC and 75 oC and pressures of 15 tonnes/196.15 cm2,17.5 tonnes/196.15cm2 and 20 tonnes/196.15 cm2.Yield of the oil and oil content of its cake were measured.Their physico-chemical properties of the oil including colour,iodine value,acid value,and free-fatty acid content weremeasured.The results show that condition giving the best yield and physico-chemical properties of the rubberseed oil for leather tanning was pressing at temperature of 75 oC and pressure of 20 tonnes/196.15 cm2.
