The operation principle of short path molecular distillation equipment is similar to high-performance thin-film evaporation equipment. The difference is that the steam chamber of short path molecular distillation equipment is additionally equipped with a built-in condenser, which can greatly shorten the distance between the heating surface and the condensation surface. So as to reduce the pressure drop maintained in the condensation channel.
The application range of short path molecular distillation equipment is very wide. It is suitable for both high distillation rate and vacuum distillation with a low operating pressure of 0.001 mbar in the heating zone. Not only that, but it can also demonstrate specific advantages in this wide field.
The practice has proved that it has many advantages in the small vacuum range and the intermediate vacuum range, and the measured pressure is related to the pressure drop after the vapor pressure drop of the boiling point can be ignored. Since the built-in condenser can handle a large volume of steam, products with higher decomposition temperature under normal pressure can be distilled or vaporized under very low vacuum pressure under mild heat load conditions.
In terms of its internal design, the equipment can be operated stably at a pressure as low as 0.001mbar, so it can distill heat-sensitive products. In this case, it is a solution for the thermal separation of products, which can complete products that cannot be separated by conventional thermal processes.

The short path molecular distillation device can install a condensation collection channel along with the inner condenser tube bundle so that different fractionation components can be removed, and different quality products can be obtained. At the same time, it can separate and pull out the droplets well, preventing droplets from reaching the condenser.
Molecular distillation relies on the difference in the average free path of molecular motion to achieve separation and does not need to reach the boiling point of the material. In addition, the operating vacuum of the equipment is relatively high, which further reduces the operating temperature.
During the molecular distillation process, the material is forced to form a very thin liquid film and is directionally pushed so that the liquid stays in the separator for a short time. For example, light molecules condense as soon as they escape, and the healing time is short, generally a few seconds or a dozen seconds. In this way, the thermal damage of the material is very small, and the separation process of the heat-sensitive substance provides an operating condition that cannot be compared with traditional distillation.
The above is about the basic operating conditions of molecular distillation equipment for distillation. In the face of the continuous emergence of new products in the market, it is very important how to choose and how to choose the correct one. Before choosing, you must clarify your goals and the products you produce. Different materials and conditions are different. At present, the function of the machine is more and more refined in order to increase efficiency. This can greatly save costs and increase production efficiency. Therefore, it is slightly different from the previous production method. You can purchase according to your requirements and reference equipment.
