FAQ

  • What are the processes of copra oil mill plant?
  • Copra oil mill plant mainly includes three processes: the pretreatment of oil, extracting and refining. Crude oil of copra→ filtering→ phosphoric acid degumming→deacidification→decolorization→deodorization→refined oil product
  • Why do we cook copra?
  • Cooking helps in better oil recovery, provides a sweet aroma and improves the shelf life of coconut oil. Heating also sterilises copra. Dried and Roasted Copra pieces are now fed into an expeller with screw press for mechanical crushing under high pressure. Oil squeezes out of copra during this process leaving the fibre out.
  • How is copra oil filtered?
  • Two filter presses are provided - one on duty while the other is being cleaned and dressed. Maximum filtering pressures reach about 60 psi. The filtered oil flows into a surge tank from where it is finally pumped to the coconut oil storage tank. Coconut oil produced from good quality copra is clear, low in fatty acid and has good coconut aroma.
  • How much oil does copra contain?
  • Copra contains approximately 63% oil, 5% is lost as moisture during the process, remaining 32% is oil cake. Oil is taken for further processing like filtering and packing. Oil cake is packed in gunny bags and sold to solvent extractors or cattle feed manufacturers. Oil extracted through expeller will has about 8% sediments/foots.
  • What is the difference between copra and coconut?
  • Coconut is a tropical woody oil plant of the Palmae. Copra can be produced through drying the coconut flesh. When the moisture content of copra reduces to 6% - 10%, it contains the copra fat of 57% - 75%. Traditional press method can be used to extract coconut oil and the coconut cake produced after extraction can be used as animal feed.
  • How is oil extracted from copra?
  • Oil squeezes out of copra during this process leaving the fibre out. Crushing is employed in 2 stages where 1st crushed copra is again crushed for the 2nd time to recover maximum oil. The left out Oil cake will still have 8% oil. Extracting oil beyond this level is not economical with mechanical crushing.
