Description
Multi-stages Molecular Distillation Assembly Equipment Line
Our Short-Path Distillation Unit, tailored for oil ethyl ester concentration and purification, embodies precision and efficiency in thermal heating processes. Specifically designed for thermal-sensitive esters separation and purification with high boiling points, like Omega-3 PUFAs found in marine fish oil, this unit excels in removing free fatty acids and concentrating unsaturated fatty acid.
The short-path distiller, an emulation of molecular distillation, features close heating and cooling surfaces with minimal resistance. Equipped with a built-in condenser, it instantly liquefies vaporized phases, maintaining high vacuum conditions, up to -0.1Pa absolute pressure—an achievement unmatched by standard evaporation and distillation equipment. This makes it ideal for materials with elevated normal-pressure boiling points, challenging conventional separation methods. Widely embraced across various industries, this liquid-liquid separation equipment offers tailored scraper options based on material characteristics, mirroring principles akin to scraper evaporators.
Molecular distillation leverages molecular free path disparities to achieve precise separation. Key conditions: the molecular free path of escaping light component molecules matches the heating-condensing surface distance, ensuring capture by the built-in condenser. In contrast, recombined molecules have shorter free paths, avoiding the condenser, achieving separation of heavy components.
Key Highlights:
- Low-Pressure Environment: Our vacuum pump group creates a specific vacuum environment, reaching up to 5Pa to -0.1Pa, effectively lowering boiling points. This facilitates the purification process, including deodorization and the removal of free fatty acids, glycerol, and solvent residues.
- High Purity: The resulting product boasts exceptional quality standards: glyceride content less than 0.5%, solvent ethanol content less than 50ppm, Gardner pigment rating less than 5, and an acid value below 0.5mgKOH/g post-deacidification.
- Molecular Weight Separation: Different esters and fractions are separated by molecular weight, with molecules evaporating under vacuum at temperatures exceeding their boiling points. This gradual temperature increase ensures optimal concentration while preventing oil degradation.
It’s important to recognize that short-path distillation is a complex process with expertise design, necessitating specialized equipment and operational expertise. Consultation with a professional or experienced technician is advisable.
We offer complete assembly solution of cost-effective equipment trusted by GOED members and other fish oil refinery plants in the world, ensuring efficient and reliable performance.
