Short Path Distillation is working under a high vacuum short time to take a mild heating for separation, concentration and purification of heat-sensitive substances and high molecular weight compounds.
Short Path Molecular Distillation - Basic Principles.
Molecular distillation, also known as short path distillation, is a specialized liquid-liquid separation technique. Unlike traditional distillation that relies on boiling point differences, molecular distillation separates substances based on the average free path of molecular movement.
As a liquid mixture flows along a heating surface and gets heated, lighter molecules escape the liquid surface and enter the vapor phase. Due to the different free paths of these molecules, setting up a proper condensation surface allows for precise separation. The pressure differential between the boiling film and the condensing surface drives vapor flow.
Why Use Short Path Distillation for your business.
When cutting-edge technology meets precision in process equipment.
Low operating temperatures under high vacuum conditions, well below boiling points. Separation of liquid mixtures with significant differences in molecular mass.
Effective separation of thermosensitive and easily oxidizable substances. High separation efficiency with mild working condition under physical separation process, protecting the separated material from contamination.
Particularly suitable for the purification of natural extracts, surpassing traditional distillation and standard thin-film evaporators. Separation of materials with similar molecular masses but distinct properties
Traditional methods often result in dark-colored, strongly flavored products with high peroxide values and low recovery rates. Molecular distillation, however, achieves a product with EPA + DHA content of 72.5%, a recovery rate of 70%, light color, pure aroma, and low peroxide value.
SPMD is considered to be one of the most promising methods for lactic acid separation due to its low evaporation temperature and short residence time which minimises the problem of thermal decomposition.
SPMD can effectively remove high concentrations of plasticizers while preserving the fatty acid composition of fish oil, and it does not produce trans fatty acids.
Essential for processes involving decolorization and purification in sectors like biofuels and environmental protection.
Short Path Molecular Distillation (SPMD) is currently the only industralized and effective separation process, which basically comprises two processes, removal of light components and evaporation of monoglycerides.
The separation in Molecular Distillation System is realized by the average free path of the vapor molecules generally less than 25mm, which is greater than the distance between the evaporation surface and the condensation surface, when heavy and light molecular matter escapes from the liquid phase main matter, light molecular matter can reach inner condenser and get captured.
