The short-range evaporator is actually a thin film evaporator integrated with a built-in condenser. In the short-range evaporator, the scraping system evenly distributes the material on the inner wall of the heated evaporator, and the evaporated steam condenses in the condenser placed inside the evaporator. The distance between the evaporator and the internal condenser is very short, with almost no pressure drop.
VTA VK100-10short-range/Molecular Distillation DeviceIt is a very compact yet highly efficient device. Single levelVK 100 - 10The land area is only long2Meter wide1Michael2Rice and can move flexibly. Due to the adoption ofVTAHigh precision feed and discharge gear pumps allow for direct discharge under high vacuum without the need for any buffer tanks, and can accurately calculate the distillation ratio of light and heavy components. It can produce hundreds of kilograms of products every day, with astonishing efficiency.
All parts in contact with the material are designed to be heatable, with no heating dead corners, and can handle melting points up to180Materials with a temperature of ℃ can also handle light components with melting points as high as140The working conditions are at ℃, as the discharge area for light components is also insulated and heated.
Can achieve the following main functions:
- Prove the feasibility of using molecular distillation for thermal separation
- Optimize the process to obtain design data for industrial production systems
- Small scale production and continuous operation can be carried out, with a processing capacity of up to10 kilogram/hour
- ·Optimize the performance of the evaporator, including determining a suitable scraper rotor
VTApilot testShort-range/molecular distillation deviceAdvantages:
- High turbulence, the scraped film always maintains a high turbulence state, increasing the transfer of mass and heat.
- The material retention time is very short, only a few tens of seconds, which reduces the thermal stress of the product
- One step distillation, no need for circulation
- The thin film is not affected by static liquid surface pressure
- Multiple scraping systems are available, providing possibilities for handling high viscosity materials.
- Low operating pressure: Low0.001mbar(0.1Pa)The operating pressure can greatly reduce the boiling point of the material and provide the gentlest thermal separation method
There are two forms of scraper rotors to choose from,WRSRoller type processing of materials with low viscosity,SKRThe metal elastic scraper rotor can handle materials with high viscosity because the elastic metal sheet exerts a loading force on the scraper, and using the scraper can produce very good film scraping and turbulence effects on the liquid film.
