  • What is the output of a screw press?
  • The output from the screw press (liquid phase ¨C crude palm oil, water; solid phase ¨C mesocarp fibre, nuts, broken kernel, and shell) is fed to two subsequent isolated production lines, namely crude oil purification and kernel recovery .
  • What is the difference between double screw press and single screw press?
  • The double screw press machine dominated the palm oil milling industries due to its larger capacity that entails a shorter processing time in comparison with the single screw press. Recurring malfunction problems were prevalent in both types of screw press system.
  • Why do palm oil mills fail?
  • Irregular maintenance and poor handling is the primary cause for machine failure. Research questionnaires were disseminated to active palm oil mills across Malaysia to acquire information on (i) the mill operation, and (ii) any malfunction issues concerning the screw press system. A total of 105 mills responded to the survey (response rate = 25%).
  • Should palm oil mills have a general maintenance scheme?
  • A general maintenance scheme has been recommended by the Malaysian Palm Oil Board (MPOB) ¨C the governing body responsible for commercial palm oil-related activity in Malaysia, as a guideline for the mills to avoid critical problems with their machinery .
