Special Oil Molecular Distillation Technology

Focused on providing professional technical solutions for special oils and fats such as fish oil, diester oil, flaxseed oil, etc., providing full production services from design to production

Core Technology Modules

Three key stages in specialty fats molecular distillation—separation, purification, and refining—achieve efficient processing through precise control and advanced techniques, delivering industry-leading product quality.

Core Technology I

Molecular Distillation Separation

Utilizing differences in molecular mean free path under high vacuum to achieve precise separation of components, especially suitable for high-boiling-point and heat-sensitive specialty oils.

  • Precision Control Accurate temperature gradient and vacuum control enable effective separation of components by molecular weight.
  • Low-Temperature Operation Processing at temperatures far below material boiling points prevents oxidation and decomposition of heat-sensitive components.
  • High Efficiency High separation efficiency in a single stage reduces process complexity and energy consumption.

Applications

Separation and extraction of functional components (e.g., CLA, phytosterols, vitamin E) and concentration of EPA/DHA in fish oil.

Core Technology II

Advanced Purification Process

Combining molecular distillation with precision filtration to remove trace impurities, off-flavors, and harmful substances from specialty oils, enhancing product purity and stability.

  • Multi-Stage Purification A multi-step purification process progressively reduces impurity levels, achieving purity exceeding 99.9%.
  • Selective Retention Maximizes preservation of functional active components while effectively removing impurities.
  • Batch Consistency Ensures uniform product quality across batches through online monitoring and feedback control systems.

Technical Advantages

Compared to traditional methods, reduces volatile component loss by over 30%, improves active ingredient retention, and extends product shelf life.

Core Technology III

Precision Refining System

It integrates multiple processes such as deacidification, deodorization and decolorization, and can effectively remove plasticizer and mineral oil through molecular level fine treatment; And avoid the generation of 3-MCPD and Ge.

  • Precision Control Accurate regulation of temperature gradients and vacuum levels enables effective separation of components by molecular weight.
  • Low-Temperature Gentleness Operation far below material boiling points prevents oxidation and decomposition of heat-sensitive components.
  • High Efficiency Achieves high separation efficiency in a single stage, reducing process complexity and energy consumption.

Quality Metrics

The acid value can be reduced to less than 0.5mgkoh/g, the peroxide value <0.5meq/kg, the color (Lovibond colorimetry) yellow <10, red ≤ 1.
