ANALAYSING OF OIL EXTRACTION PROCESS FROM PUMPKIN SEEDS BY USING NON-TRADATIONAL METHOD OF ENERGY

Abstract

Oilseed processing and oil extraction processes are designed to obtain high quality oil with minimal undesirable components, achieve high extraction yields and produce high value meal. There are several techniques for extracting oil from oilseeds. Two common oilseed extraction processes are solvent extraction and mechanical extraction using a screw press. Today in the United States, mechanical oil expression is not widely used due to low oil recovery. However, the use of screw press is preferred by small processors because of its low capital cost. Solvent extraction with hexane is the standard practice in today’s modern oilseed-processing facilities. Experiments were conducted to evaluate the effect of temperature and pressure on the yield and quality of the oil obtained. The oils extracted from the structured bed presented superior quality compared with the seed oil, in relation to all parameters evaluated.
