The evaluation of walnut oil extraction parameters

Popis výsledku v původním jazyce

Walnut is known because of its high polyunsaturated fatty acids content, they reduce blood pressure, total and LDL cholesterol. In the walnut oil production, it is very important to find appropriate parameters to pressing the oil from seeds. In this study, walnut oil was obtained by pressing by screw press UNO FM 3F by Farmet Company, Czech Republic. The effects of pressing frequency of 30, 50, 70, and 90 rpm and nozzle size of 6, 8, 10 mm in pressing experiments were monitored. The walnuts oil density was 876.3 kg/m and seed oil content was determined by extraction ranges 70.17% in dry basis. The results have confirmed that when the screw rotation speed is changed from 30 to 90 rpm, the press capacity increases on average from 0.71 to 2.05 kg/h but simultaneously the oil yield reduces from 41 to 12%. Finally, the optimal pressing parameters were determined to 30 rpm and nozzle size of 6 mm.
