The Short-path Distillation unit is a specialized technique for liquid-liquid separation. The average free path of vapor molecules is greater than the distance between the evaporation and condensation surfaces under high vacuum conditions, thus allowing for the separation of liquid mixtures based on the differential evaporation rates of components in the feed liquid.
Short-path distillation unit application scope:
1. Chemical Industry: including aromatics oil purification, high polymer intermediate purification, and wool fat extraction, etc.
2. Fields: such as extraction of natural vitamins, AE synthetic amino acids, and glucose derivatives.
3. Food Industry: Refining fish oil, acid removal, and mixed oil separation
4. Other Sectors: Oil Industry, Chemicals, Environmental Protection.
Key Features of Short-Range Distillation Unit:
Operating at temperatures well below the boiling point of the materials, resulting in shorter material residence time, which is beneficial for the separation of high-boiling point, highly thermosensitive, and easily oxidizable materials.
Effectively removing substances from liquids such as organic solvents and odors is a highly effective method for desolventizing liquids after solvent extraction.
3. The short-path distillation unit can choose evaporation to remove other impurities, and the multi-stage separation can simultaneously separate two or more substances.
4. The vacuum level during the distillation process is extremely high, reaching below 0.1 Pa, and a high vacuum can also be achieved internally. Generally, molecular distillation is conducted under very low pressure, hence the material is less prone to oxidation and degradation.
5. The distillate film is thin with high heat transfer efficiency, with a thickness less than 0.5 millimeters.
6. High degree of separation; molecular distillation can separate conventional substances that are difficult to isolate.
7. No boiling or bubbling occurs. Molecular distillation is a free evaporation process at the liquid surface. It is carried out under low pressure, with no dissolved air in the liquid, hence the entire liquid does not boil and no bubbles are formed during the distillation process.
