Advantages of Short-Path Molecular Distillation System

The short-path molecular distillation system can eliminate thermal decomposition, polymerization, or deterioration produced during the thermal separation process. Therefore, molecular distillation is the most gentle and safe distillation method among thermal separation products, particularly suitable for polymers, high-boiling-point, high-viscosity substances, and organic mixtures with poor thermal stability. In a high-vacuum environment, molecular distillation equipment boasts advantages such as low distillation temperature, short heating time, and fast separation. It has been widely used in the extraction of various natural ingredients, allowing for the release from the constraints of chemical processing methods, truly preserving the natural characteristics of the product. It is regarded as a protector and a returner of natural quality.

Short-path molecular distillation offers the following separation advantages:

Material heating time is shortened.

The rotating scraper drives the material liquid to spiral down from the heating surface, detaching from it, and the separated material escapes from the heating surface. The condenser quickly cools and collects it, minimizing the contact time between the material and the heating surface. Eliminates thermal decomposition, polymerization, or deterioration.

2. Low evaporation temperature

Compared to traditional distillation, the liquid distributors and rotating blades are evenly distributed on the heating surface, reducing the pressure difference generated by the still liquid surface. The distance between the heating and condensing surfaces is shorter, allowing light molecules to rapidly condense after escaping from the heating surface, lowering the pressure generated by gas transfer and making it easier to achieve lower evaporation pressures. As long as the free path of motion of the light molecules escaping from the vapor surface is greater than the distance between the vapor and condensing surfaces, the distillation temperature is significantly lower than that of traditional distillation.

3. Self-cleaning heated surface

The rotating scraper glides over the heating surface, continuously stirring and refreshing the liquid film, preventing material from bubbling and scaling on the heating surface. It can be successfully applied to the concentration and separation of materials prone to bubbling and scaling on the heating surface in traditional distillation processes.

High evaporation efficiency, adaptable, and easy to operate.

The rotating scraper evenly distributes material over the heating surface, maintaining a high turbulent state of the liquid film to accelerate heat transfer and reduce heat loss. The structure is simple, easy to clean, and offers free start and stop, making it suitable for small-scale chemical production with a variety of products and discontinuous processes.

Due to the aforementioned characteristics of short-path distillation, which can eliminate thermal decomposition, polymerization, or deterioration during the heat separation process, this technology has become the mildest distillation method for separating target products. It is particularly suitable for concentrating, purifying, or separating polymers, high-boiling-point, high-viscosity substances, and organically mixed compounds with poor thermal stability. This technology is used for extracting natural health products, freeing itself from the constraints of chemical processing methods, and truly maintaining their natural properties. It is regarded as a protector and a returner of natural quality.
