Process information
| Stage | Concentration, after refining and before deodorisation |
|---|---|
| Feed | Refined and transesterified fish oil |
| Output | Concentrated EE oil from 30% up to 98% total omega-3 |
| Records | Vacuum, temperature, feed mass and cut points logged per batch |
Technical detail
| Principle | Under high vacuum the mean free path of the vapour exceeds the distance to the condenser, so evaporation happens without boiling the bulk oil |
|---|---|
| Temperature | Kept well below the point at which EPA and DHA begin to isomerise or degrade |
| Residence time | Measured in seconds, which is what protects oxidation-sensitive fatty acids |
| Cut points | Set per target ratio, so EPA-rich and DHA-rich cuts are produced deliberately rather than as a by-product |
