Short range molecular distillation equipment


Working site of sy-4a short range distiller
Many materials, such as petroleum heavy residue, chemicals, pharmaceuticals and natural foods, health products and fatty acids, are often heat sensitive, viscous and / or have high boiling points. In order to separate these materials from their other components and maintain the quality of the products, rectification can only be carried out at low boiling temperature or even below boiling temperature, and the thermal decomposition or polymerization can only be reduced to a small extent in a short time to eliminate the damage to the products.
When the operating vacuum is about 500pa, it can be carried out in the scraping film evaporator or falling film evaporator. However, if the distillation must be operated in medium and high vacuum (such as the pressure between 0.001 ~ 100Pa), there will be a problem. Evaporators with external condensers are excluded from the distillation process in which the vapor pressure of the product does not exceed the pressure difference between the heating surface and the condensing surface.
In contrast, the sy type short range evaporator is suitable for this application, and the condenser is manufactured in the evaporator directly opposite the heating distillation. Therefore, the short-range evaporator is a new separation technology which has not been widely used in industrial production and can solve the problem that a large number of conventional distillation technology can not solve.
There are three types of film scrapers: rolling film, sliding film scraping film and hinge scraping film. Different film scrapers are selected according to the viscosity and treatment properties of materials.

Short stay time The film scraper makes the liquid film stay on the heating surface for a short time.
Low distillation temperature Because the condenser is directly opposite to the heating surface, the pressure difference is reduced, so the material can be distilled at low temperature even without reaching the boiling point.
Viscous substances and products contain solids When the blade is deeply immersed, the film will cause a strong shear and mixing effect, which reduces the viscosity of the solution to be treated. It is suitable for treating the viscosity to 50pas and preventing scaling on the heating surface, especially for solid containing liquid.
Thin distillation level The function of the film scraper is to scrape the feed liquid into a thin liquid film. The separation is complete.
Thermal sensitive materials
High separation ratio The precision scraper uses a thin liquid film that is evenly distributed on the heating surface, causing the entire heating surface to be wet. This allows the operating unit to have a high boiling separation ratio. This means that more than 90% of the entry in the list is evaporated, and the level in the constant residue can be completed.
