Laboratory Small Capacity Vacuum Rotary Vacuum short path Distillation Evaporator Equipment
Laboratory Small Capacity Vacuum Rotary Vacuum short path Distillation Evaporator Equipment Working principle:
Molecular distillation is a distillation process in which molecules evaporated on the heating surface reach the condensation surface as short as possible under high vacuum (< 10Pa) to condense, so as to realize liquid-liquid separation. When the distance between heating surface and condensation surface is less than or equal to the average free path of evaporated molecules under operating vacuum and temperature, the distillation process is also called molecular distillation.
Distillation process: the material enters the short-range distiller from the upper flange cover, and the distribution plate is continuously and evenly distributed on the vertical cylinder heating surface. When the material falls by gravity, the rotating film scraping device forces the extremely thin turbulent liquid film on the heating surface After a short distance, the evaporated molecules reach the built-in condenser and condense. They are discharged through the discharge port at the bottom of the evaporator. The heavy components enter the residue collection tank of the short-range distiller and are discharged from the side outlet.
Laboratory Small Capacity Vacuum Rotary Vacuum short path Distillation Evaporator Equipment Performance features:
1. High working vacuum and low distillation temperature;
2. Large heat transfer coefficient and high evaporation efficiency;
3. The heating time is short, the "dead angle free" design of DZ series short range distiller avoids the accumulation of materials in the distribution plate, heating surface and scraping film system, and reduces the thermal polymerization and thermal decomposition of heat sensitive substances.
Laboratory Small Capacity Vacuum Rotary Vacuum short path Distillation Evaporator Equipment Structural features:
The transmission device and mechanical seal of the short-range distiller are specially designed and manufactured to meet the long-term stable operation of high-precision equipment. According to the working condition and material characteristics of the short-range distiller, the reduction ratio of the transmission device, the lubrication mode of the mechanical seal (forced circulation lubrication, static lubrication) and the cooling mode of the mechanical seal are determined.
1. The evaporation cylinder is processed as a whole without intermediate flange connection;
2. The surface finish of the cylinder body is high and it is not easy to stick materials: the surface finish of the fine grinding can reach Ra0.8 μ m, and the special polishing finish can reach Ra0.2 μ m;
3. The unique design of liquid distributor and splash proof device can effectively guarantee the product quality; the high-precision design and manufacture of DZ series short-range distiller can ensure the long-term stable operation of the device, the evaporation process is very soft, almost no splash and entrainment, in most cases, even without splash proof device, it can meet the product requirements. When dealing with some special materials and having special requirements for products, the anti splashing device of DZ series short range distiller can more reliably guarantee the product quality;
4. Various types of film scraper are optional, with wide application range: inclined groove scraper, roller type, metal hinge type, fixed scraper type, etc.
Laboratory Small Capacity Vacuum Rotary Vacuum short path Distillation Evaporator Equipment Applications:
1. Control the temperature of heating body by adopting our own thermal superconducting technology. The temperature control accuracy can be 0.5°C.
2. The equipment has a small size, simple piping, short stating time and is easy to operate. The energy consumption of our equipment is reduced by 25% compared with using conduction oil to heat.
3. By Adopting our own cold trap technology, we can save cooling water and vacuum pipeline, thus to ensure the high efficiency and selectivity of the distillation process.
4. Our self-made oil diffusion pump with unique bundling nozzles has a very high compression ratio, and the backpressure can reach more than 160Pa, thus reduce greatly the demand for fore vacuum system. So the energy efficiency ratio is improved and at the same time the cost of production and maintenance is reduced.
5. We have developed automatic control of continuous rectification section of molecular distillation technology. Our equipment can separate natural matters, complex components and matters with a smaller molecular weight difference. Thus we can help our customers to improve their product quality and competitiveness.
6.We design equipment according to material features and client's requirements. We can make equipment from 0.1m² to 30m².

Polishing:
Polishing is vital for tanks. Tanks should be polished wholly inside and outside.
Therefore it can ensure there is no place for the bacteria to hide in tanks.
Our polishing system consists of auto and semi-auto polishing machine and manual polishing.
Each tank is polished three times and more polish for the key place.
Welding:
Our argon central system for welding provides 100% pure argon to protect tanks from distorting during welding.
