  • Do worm screws in palm kernel oil screw press need to be replaced?
  • Worm Screws in palm kernel oil screw press have been found to fail often and usually require constant replacement. The failure rate is also more with locally fabricated worm screws which usually need to be replaced after about 4 – 5 batches of inlet capacity of palm kernels have been processed.
  • Why is palm kernel oil worm screw bad?
  • This causes downtime in the machine’s operations and the wear of the worm screw deposits metal particles in the extracted oil which should be avoided at all costs as palm kernel oil is usually refined for food and cosmetic use amongst others.
  • Can worm screws be fabricated locally in Nigeria?
  • The method currently used for the local fabrication has been discussed and recommendations have been made that could result in better useful life of the locally fabricated worm screw. The limitation preventing Nigerian Engineers from fabricating the worm screws with best engineering practices are also discussed.
  • What is worm shaft in a screw press?
  • Design of worm shaft of the expeller The worm shaft is the main component of the screw press and is acted upon by weights of material being processed, pulley and screw thread. In operation, the worm shaft conveys, presses and squeezes the material (digested palm fruit) for oil extraction.
  • Why is palm oil a bottleneck in Nigeria?
  • The traditional method of palm oil processing is time consuming, laborious, hazardous and inefficient resulting in the production of low quality oil. Oil extraction still remains a critical bottleneck particularly the level of small and medium scale processors in Nigeria .
  • How much does a palm oil press cost?
  • The production cost of the press is $650 and it is powered by a three- phase 5hp electric motor. 1. INTRODUCTION The oil palm (Elaeis guineensis) is an important economic tree that is grown in Asia, Africa and South America . It is the principal source of palm oil which is an edible vegetable oil.
