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:
- odor, flavor removal
- free fatty acid removal
- color reduction (heat bleaching)
- peroxides destruction
Minimise:
- losses in essential fatty acids (EPA/DHA)
- creation of transisomerisation (TFA)
- polymerisation
- breakdown vitamine A+D+E
Organoleptic and 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.
