Screw Pressed Extraction and Properties of Palm Oil
Self -made single -screw press was used to extract oil from the bunches and fruit of oil palm, respectively. Then the oil yields of bunches and fruit was compared, the physical and chemical properties of palm oil was analyzed. The results indicated that: The oil yield was improved when the bunches was sterilized, stripped, digested and then pressed; acid value, melting point, iodine value, saponification value of palm oil met the National Standard, the contents of copper, iron, water and volatile matter, insoluble impurities and unsaponifiable matter were all rare and met the National Standard; The operation conditions and self-made equipments met the needs of palm oil extraction. The results would lay a foundation for the development of small-scale palm oil extraction equipment in the future.
