How a fully engineered, SS316L-built modular extraction platform helps R&D teams de-risk process development before commercial scale-up.
Beyond the Boiling Point: The Industrial Power of Molecular Distillation

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.
Beyond Fabrication: The Dedication Behind Delivering Complex Process Equipment

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.
What Output Concentration will Get from Our Fish Oil Omega-3 Enrichment Concentration Line
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.
All You Need to Know About SPDU for Fish Oil Concentration

The separation of molecular distillation is based on the difference between the average molecular free range of different components, which is proportional to the distillation temperature (thermodynamic temperature), but it is inversely proportional to the distillation pressure and the average diameter of the molecules squared.
The smaller molecular weight fatty acid ethyl ester has smaller molecular average diameter at the same temperature and pressure condition, with a larger molecular free range, and thus more easily “Escape” from the heating liquid surface by the condenser capture, and ultimately become the “light-phase” component of molecular distillation, other larger molecular weight fatty acid ethyl esters (such as EPA ethyl ester, DHA ethyl ester) is more likely to become the “heavy-phase” component of molecular distillation.

The Success Story of Molecular Distillation in Fish Oil Ester Concentration and Biodiesel Production

The state-of-the-art in concentrating Omega-3 fatty acids, a process pivotal in this evolution, shifted towards the fractionation of their ethyl or methyl esters. This method circumvents the high-temperature problem by employing multi-stage Short Path Distillation. This innovative approach has significantly improved the purity and concentration of Omega-3 fatty acids, with total EPA and DHA content achievable up to 70% or higher. Additionally, the variability of the EPA to DHA ratio can be finely tuned through control of distillation conditions and the degree of concentration.
Molecular Distillation Systems for the Concentration of Omega-3 Fatty Acids

The molecular distillation process is highly efficient in removing impurities and producing high-quality omega-3 concentrates, but it requires specialized equipment and expertise. It is important to work with a reputable supplier who follows strict quality control measures to ensure the safety and purity of the final product.
the multi-stage molecular distillation process for fish oil concentration is an effective method for producing highly purified fish oil with minimal thermal degradation. The use of multiple stages allows for a high degree of separation and concentration of the desired molecules, resulting in a product that is suitable for a variety of applications, such as nutritional supplements and pharmaceuticals.
