Product Introduction
Product principle and features
1. The operating temperature of short-path distillation (molecular distillation) is much lower than the boiling point of the material:
It is known from the principle of short-path distillation (molecular distillation) that the separation of mixtures is achieved due to the different properties of the mean free path of different types of molecules escaping from the liquid surface, and does not require boiling, so short-path distillation (molecular distillation) is far away. Operates at temperatures below the boiling point. This is fundamentally different from conventional distillation.
2. Short heating time:
According to the principle of short-path distillation (molecular distillation), the distance between the heated liquid surface and the condensation surface requires the mean free path of light molecules, and the light molecules escaping from the liquid surface reach the condensation surface almost without collision, so they are heated. Time is short. In addition, the mixed liquid is in the form of a film, so that the area of the liquid surface and the heating surface is almost equal, so that the heating time of the material in the distillation becomes shorter. For vacuum distillation, the heating time is one hour, while the short-path distillation (molecular distillation) is only ten seconds.
Product advantages:
1. Due to the high vacuum degree of short-path distillation (molecular distillation), low operating temperature and short heating time, it has the incomparable advantages of conventional methods for the separation of high boiling point, heat sensitivity and easily oxidizable materials, and can ensure the natural quality of materials. . Can be widely used in the extraction of natural substances.
2. Short-path distillation (molecular distillation) not only efficiently removes low-molecular-weight substances in liquids, such as organic solvents, odors, etc., but also selectively steams out the target product and removes other impurities, so it is regarded as the protector of natural quality and returner.
3. Short-path distillation (molecular distillation) can realize physical processes that cannot be achieved by traditional separation methods. Therefore, it is widely used as a means of deodorization, decolorization and purification in the separation of some high-value materials.
The left picture shows the basic workflow of molecular distillation: the feed liquid enters the distiller under vacuum, and is rapidly expanded into a thin film on the inner wall by the rotation of the scraper, and the downward movement is in full contact with the evaporation surface, and the heating wall (orange red) part) and high vacuum (yellow part) drive the more volatile components (Distillate) to collect on the surface of the built-in condenser in close proximity, while the less volatile components (residue) continue to move down the inner wall of the distillation column , and is collected, while the separated distillate flows out through a separate discharge port. Depending on the application, the desired product will be a distillate, or a residue. The compressible low molecular weight components were collected in a cold trap in the upper stream section equipped with a vacuum system.
product description:
The main equipment of the pilot/industrial short-path evaporation plant is composed of raw material tanks, short-path stills, cold traps, valves and pipe fittings, inlet/outlet pumps, two-stage vacuum systems, control systems and other main components. All equipment materials are made of 316L stainless steel. , The structural design of the short-path distiller is mainly based on the processing capacity and process requirements. The heating method mainly adopts heat transfer oil/steam, the built-in condenser generally adopts the tube heat exchanger or the built-in coil type, and the cooling form mainly adopts the circulating chilled water. or hot water for heat exchange.
The control system of the device adopts PLC integrated control, and the automatic control system can read and view the stored historical process data through the viewing process interface, and can access the curves of various process parameters.
