Heating time is short:
Due to the unique structure of the scraper jacketed glass reactor film evaporator, knifing instruments have pumping effect, make the material stay in the evaporator for a short time; The other, on the heating of the evaporator due to the high turbulence of the thin film products not stranded in the evaporator surface. Therefore, particularly applicable to the evaporation of the thermal sensitive material.
High evaporation strength:
In the boiling point of the material is reduced, increased with the temperature difference of heat medium; The function of the membrane scraper, reduced the thickness of liquid film of present state of turbulence, reduces the thermal resistance. At the same time, in the process of the inhibition of materials in the heating surface and wall, scale, and with good heat exchange, therefore, to improve the total heat transfer coefficient of the scraper film evaporator.
Large elasticity of operation:
It is because of scraper film evaporator * performance, to make it suitable for processing heat sensitive and requires stable evaporation, high viscosity and viscosity sharply increased with the concentration of the material, its evaporation evaporation process can smoothly. It can also successfully applied to containing solid particles, crystallization, aggregation, scaling, and so on and so forth material evaporation and distillation.
Short-range distillation apparatus is a special kind of liquid-liquid separation technology. Under the condition of high vacuum, the mean free path of steam molecules is greater than the distance between the surface evaporation and condensation surface, thus can make use of material liquid evaporation rate of the component parts.
Short-range distillation unit scope of application:
1. Fine chemical industry, such as aromatic oil cbd centrifugal extractor purification, purification, polymer intermediates lanolin extract etc.
2. The medical field, such as the extraction of natural vitamin AE synthesis of amino acid and glucose derivatives;
3. The food industry, such as refined fish oil, acid, refining high alcohols, mixed oil separation;
4. Other areas: the oil industry, chemical industry, environmental protection.
Short-range distillation unit key features:
1. At far lower than in the boiling point of the material temperature operation, short staying time of material, is advantageous to the easy oxidation of high boiling point and heat-sensitive material separation;
2. Effectively remove organic solvent, smell of hemp extraction centrifuge liquid material, such as solvent extraction is after desolventizing a very effective method for liquid;
3. Short-range distillation unit can choose evaporation, among other impurities, multi-stage separation can separate two or more substances at the same time;
4. A high vacuum degree in the process of distillation, can achieve 0.1 pa below, inside can also get higher vacuum degree. In general, molecular distillation was conducted under the pressure of very low, so the material is not easy to be oxidative damage;
5. The distilled liquid thin film, high heat transfer efficiency, less than 0.5 mm thick;
6. High degree of separation, molecular distillation is difficult to separate the conventional material can be separated;
7. No boil and bubble phenomenon. Molecular distillation is a liquid layer on the surface of the evaporation process of freedom. Under low pressure, the liquid not dissolved in the air, so the liquid will not boiling, no air bubbles in the process of distillation.
In liquid-liquid separation technology, distillation (distillation) is one of the most common is also applied to a wide range of technology, we heard the common distillation, extractive distillation, azeotropic distillation, heat pump distillation, reactive distillation, etc., but the molecular distillation heard no? What the hell is it?
