How we helped a customer turn standard fish-oil ethyl esters into premium 46/38 and 85%+ EPA/DHA products — with higher yield and lower urea consumption.
Single-pass short path molecular distillation of fish oil ethyl esters is not a magic bullet—it’s a highly efficient, high-recovery pre-concentration tool. 25 t/d is a sweet spot. At this industrial scale, which has been demonstrated to be most commercially cost-effective production line, you’re producing 8+ tonnes per day of enriched fraction.
Achieving consistent enrichment levels of up to 75% EPA and DHA while yielding bioactive ingredients of 68% and beyond requires systematic project planning, experienced process practical expertise, and in favor of a rigorous “Basic Engineering Package” (BEP)
Continuous Multi-Stage (8–10 Stages) have been optimized and practised in past decades to ensure high efficiency and productability in large scale production plants.
The most economical foundation for the co-production of multiple product fractions (e.g., 50/10, 40/20, 36/24, 25/35, 10/40 and 33/22) simultaneously.
Innovator’s Note: By shortening the heating time to mere seconds, we drastically lower the probability of thermal decomposition, ensuring high efficiency without compromising material integrity.
Strategic Insight: The physical gap between the evaporator and condenser is a precisely engineered distance based on the calculated molecular motion of the target substance.
Innovator’s Note: This specific pumping sequence is not just about reaching depth; it is designed to maximize the service life of high-performance pumps by ensuring they only operate within their optimal pressure regimes.
Why do the workers spend hours reinforcing a crate that is already built?
Because they possess a “Custodian Mindset.”
To a process scientist, a Distillation Column is a vessel for separation.
To our loading team, that 3.3-meter-tall crate is a fragile object that demands respect.
Simply speaking, with the right fatty acids processing strategy, our lines routinely deliver basic, mid-, high-, and ultra-high concentrates (≈30-60–95% EPA+DHA), and—with chromatography—near-pure EPA-EE or DHA-EE at ≈95–99.7%. Your exact number depends on feed GC, route (EE or rTG), stage count, and polishing steps.
As someone deeply involved in the process and control industry, I often encounter queries about the best practices for extracting and concentrating Omega-3 fatty acids.
This process is crucial, as Omega-3s are essential for human health but notoriously delicate to handle.
The ideal vacuum condition for concentrating Omega-3 fatty acids must strike a balance between low enough to reduce the boiling point and minimize thermal degradation, yet high enough to maintain efficient distillation and separation for target yield. Typically, vacuum levels around 5 to 0.1 Pa are most effective for these purposes.
Short path distillation is a powerful technique used in the purification and concentration of fish oil fatty acids, particularly for increasing the EPA/DHA ratio.
This process allows for precise control over temperature and vacuum conditions, enabling the separation of different components based on their boiling points and molecular weights.
By fine-tuning these parameters, it’s possible to selectively concentrate EPA and DHA while minimizing the loss of other beneficial compounds.
At the stage of fatty acid concentration process, the refined fish oil undergoes short path distillation, a process that operates under high vacuum and minimal heat to prevent oxidation and degradation of the Omega-3 fatty acids.
This technique is highly effective in separating and removing low molecular weight contaminants (e.g., PCBs, dioxins, plastisizers, and heavy metals) while concentrating the EPA and DHA content.
High-performance equipment will allow for fine-tuning these parameters to target the specific boiling points of POPs without degrading the quality of the Omega-3 fatty acids.
Embarking on the journey of enhancing oil quality demands a technological marvel, and short path molecular distillation stands as the unsung hero in the fish oil refining process. In my realm as a seasoned sales specialist for short path molecular distillation equipment, I’ve witnessed the transformative power of this cutting-edge technology.
