Description
Technical Parameters
Centrifugal molecular distillation is a new distillation method that combines molecular distillation and centrifugal technology, which can effectively separate two or more liquids with similar boiling points. Its working principle is to use rotational centrifugal force to throw molecules away from the liquid surface of the distillation flask, and move along the wall of the centrifuge tube, ultimately being instantly precipitated. It is a technology that uses a rotating centrifugal force field to accelerate evaporation and separation, widely used in chemical, pharmaceutical, food and other fields for the purification, purification and separation of various compounds.

Product Comparison
Centrifugal Molecular Distillation is a technology that utilizes centrifugal force fields to accelerate evaporation and separation. It differs from Molecular Distillation in terms of equipment, sampling methods, and experimental processes.
1. Equipment used:
- Molecular distillation: Molecular distillation typically uses traditional molecular distillation equipment, including distillation towers, heaters, condensers, and vacuum systems.
- Centrfugal molcular distilltion: Centrifugal molecular still uses centrifugal molcular ditillation equipment, which includes a rotating conical evaporator, condenser, and vacuum system. The rotating conical evaporator generates centrifugal force through high-speed rotation, evenly distributing the sample on the surface of the evaporator to increase evaporation efficiency.
2. Sampling method:
- Molecular distillation: Molecular distillation is usually operated by continuous feeding and continuous collection of products.
- Centrifugal molecular distilltion: Centrifugal molcular distilltion can be operated using continuous feeding and continuous collection methods, as well as intermittent feeding and intermittent collection methods. The centrifugal force field can evenly distribute the sample on the surface of the evaporator, reduce dead corners and accumulation, and facilitate product separation.
3. Experimental process:
- Molecular distillation: In molecular distillation, the temperature and pressure are controlled within an appropriate range, and evaporation separation is carried out under vacuum conditions. Usually applied to substances with high boiling points, high viscosity, or easy thermal decomposition.
- Centrifugal molecular distilltion: During the experimental process, the mixture is first added to a rotating conical evaporator, and then centrifugal force is generated through high-speed rotation to evenly distribute the thin layer of the mixture on the surface of the evaporator. Next, evaporation separation is carried out under vacuum conditions and the product is collected through the condenser. Centrifugal force can improve mass transfer rate and evaporation effect.

In summary, centrifugal molcular distilltion uses it still in terms of equipment compared to molecular distillation; In terms of sampling methods, continuous feeding and continuous collection can be selected, as well as intermittent feeding and intermittent collection; In the experimental process, the evaporation efficiency and mass transfer rate were increased through the centrifugal force field. Centrifugal molcular distilltion is suitable for some demanding separation processes and can provide higher separation efficiency and product quality. However, it should be noted that centrifugal molcular distilltion equipment has a higher cost and greater operational difficulty, making it more suitable for specific application fields and needs.
Applications
Although both centrifugal molcular distilltion and molecular distillation belong to the category of liquid separation technology, there are significant differences in their applications, which are not only reflected in equipment and collection methods, but also in their unique operating principles.
The working principle of centrifugal molcular distilltion cleverly combines the characteristics of high-speed rotation and centrifugal force field. In centrifugal molcular distilltion equipment, the liquid is placed in a high-speed rotating conical evaporator. As the rotational speed increases, the centrifugal force field gradually strengthens, forcing the liquid to form a uniform and extremely thin liquid film on the surface of the evaporator. The formation of this thin layer greatly increases the contact area between the liquid and the evaporation interface, thereby significantly improving the mass transfer rate and evaporation effect. This unique operating method enables centrifugal molcular distilltion to perform excellently in processing high boiling point, high viscosity, or thermosensitive liquids, and efficiently separate target components.
In contrast, molecular distillation mainly relies on increasing temperature and vacuum degree to achieve fine separation. In the process of molecular distillation, by increasing the temperature and reducing the system pressure, the molecules in the liquid can obtain sufficient energy to overcome the intermolecular forces, thereby achieving evaporation at low pressure. The evaporated molecules are condensed back into liquid in the condenser, thereby achieving liquid separation. Molecular distillation technology is particularly suitable for separating liquid mixtures with similar boiling points and strong intermolecular forces.
The different application characteristics of these two separation technologies mainly stem from their unique working principles. Centrifugal molecular distillation utilizes the advantages of centrifugal force field to form a uniform thin layer on the surface of the conical evaporator, thereby improving mass transfer rate and evaporation efficiency. This technology is particularly suitable for processing liquid mixtures that are difficult to separate through traditional distillation methods. Molecular distillation, on the other hand, achieves fine separation of liquid mixtures by increasing temperature and vacuum degree, utilizing the free motion characteristics between molecules.
To better understand the difference between these two technologies, we can give a simple example. Assuming we need to separate the target component from an oil sample containing high boiling point components. If we choose centrifugal molcular distilltion, we can use the centrifugal force field in the centrifugal molcular distilltion equipment to enhance the evaporation effect, so that high boiling point components can be effectively separated during the rotation process. If we choose molecular distillation, we need to increase the temperature and vacuum degree to evaporate high boiling point components at low pressure and collect them through a condenser. Although both methods can achieve separation goals, there are significant differences in their operating principles, equipment requirements, and scope of application.
In summary, although centrifugal molcular distilltion and molecular distillation are both important components of liquid separation technology, they have significant differences in operating principles, equipment requirements, and applicability. Therefore, when choosing a specific separation technology, we need to comprehensively consider factors such as the properties of the liquid to be separated, the separation target, and production conditions to ensure the selection of the most suitable separation method.
