Deodoriser

A deodoriser is an equipment for deodorising, the final stage in vegetable oil refining. Deodorising removes odoriferous material, free fatty acids and other undesired minor components to produce a bland oil with a good shelf life.

State-of-the-art

Over the latest years, the aim of a state-of-the-art deodorising became:

Maximise:

  • odour, flavour removal
  • free fatty acid removal
  • colour reduction (heat bleaching)
  • peroxides destruction

Minimise:

  • losses in essential fatty acids (EPA/DHA)
  • creation of transisomerisation (TFA)
  • polymerisation
  • breakdown vitamine A+D+E

Organoleptic & Nutritional Value

Final customers require a perfect oil with high organoleptic and nutritional values, even one year after production.

Deodorising stages

The different stages in deodorising are :

  • Deaeration
  • Heating
  • Deodorising / steam stripping
  • Heat recovery / cooling
  • Final cooling
  • Polishing filtration

Top quality products require optimal conditions at all stages.
