Technologies for Oil Extraction: A Review

Abstract:
This paper is designed for people who have little or no technical background or earlier knowledge of oil extraction processing. It provides a vital introduction to both traditional and improved methods for the extraction of vegetable oil from oilseeds. Comparisons are made between different improved technologies aim to show under what circumstances they may be technically appropriate or inappropriate. The improved method include; Mechanical Extraction (oil expeller, motorized screw press) and solvent extraction (chemical extraction). Also problems associated with each method and the needs for more research for the improvement of the methods are analyzed. It has been shown that for any developing country to effectively adopt modern methods in the production of edible vegetable oils, improvement on the existing traditional methods, environmental factors need to be studied. This can be achieved through more research in the recommended area of need .Also oil expression technology in order to create an interest and awareness of the technology, which may help improving the rural development as wealth and self-employment.
