Process information

分子蒸留による精密な濃縮 process information
StageConcentration, after refining and before deodorisation
FeedRefined and transesterified fish oil
OutputConcentrated EE oil from 30% up to 98% total omega-3
RecordsVacuum, temperature, feed mass and cut points logged per batch

Technical detail

PrincipleUnder high vacuum the mean free path of the vapour exceeds the distance to the condenser, so evaporation happens without boiling the bulk oil
TemperatureKept well below the point at which EPA and DHA begin to isomerise or degrade
Residence timeMeasured in seconds, which is what protects oxidation-sensitive fatty acids
Cut pointsSet per target ratio, so EPA-rich and DHA-rich cuts are produced deliberately rather than as a by-product
