The Influence of the Main Technological Parameters of Cold Pressing of Local Varieties of Sunflower Seeds on the Yield and Quality of Oil

The scientific research studied the influence of the main technological parameters (rotation speed of the screw shaft and the thickness of the press outlet slot) during cold pressing on the yield and quality of oil from local varieties of sunflower seeds.Using Response surface methodology, it was revealed that, at a shaft rotation speed of 35 rpm and a slot thickness of the outlet opening of 7.5 mm, the residual oil content of the cake will be in the range of 10-10.5%;and the acid number of the resulting oil is in the range of 1.65-1.7 mg KOH.
