Molecular distillation, also known as short-path distillation, is a relatively new liquid-liquid separation technology that has not been widely used in industrial production. Its application can solve many problems that cannot be solved by conventional distillation technology.
1. Ordinary distillation is the separation operation at the boiling temperature, while molecular distillation can be separated at any temperature as long as there is a sufficient temperature difference between the cold and hot surfaces. Therefore, the operating temperature of molecular distillation is much lower than the boiling point of the material.
2. Ordinary distillation has the phenomenon of bubbling and boiling, while molecular distillation is the free evaporation of the liquid film surface.
3. The evaporation and condensation of ordinary distillation are reversible processes, and the liquid and gas phases are in dynamic phase equilibrium. In the process of molecular distillation, the molecules escaped from the heating surface are directly shot to the condensation surface, and theoretically do not return to the heating surface. possibility, so molecular distillation does not have substances that are not easily separated.

Abstract: Oil deacidification is an important step in food processing, which aims to remove free fatty acids in oil and improve its quality and stability. Traditional deacidification methods have some limitations, such as low efficiency, high energy consumption, and loss of nutrients. In recent years, molecular distillation technology has gradually attracted attention as a new deacidification method. This article will introduce the application of molecular distillation in oil deacidification, including the principle, operation process and advantages, and focus on the outstanding advantages of Aishengke in molecular distillation technology.
Vitamins are products that are closely related to people's lives, and have become one of the main bulk products in the international pharmaceutical and health care products market. The amount of vitamin E is the largest, followed by vitamin A, vitamin C, vitamin D and so on. With the growth of economy and the improvement of people's living standards, the demand for vitamin products will further increase, and people's requirements for their quality and grade will also further increase. Therefore, as an important separation technology in the production of many vitamins, molecular Distillation technology will also play an increasingly important role in the vitamin industry.
Glyceryl monostearate (GMS), abbreviated as monoglyceride, is produced from natural vegetable oils and fats. The active ingredient is purified by molecular distillation technology to more than 90%, also known as molecular distillation monoglyceride. It is the most widely used food Additives, safe to use in the production and processing of food, medicine, plastics, etc., account for more than half of the emulsifier consumption in the market.
The principle of molecular distillation is to make use of the different degrees of affinity between different molecules. By controlling the conditions such as temperature and pressure, the mixture begins to vaporize. Different components in the vapor form liquids in the condenser and are separated according to their boiling points. This distillation method not only has a good separation effect, but also can be repeatedly separated and purified, and is widely used in chemical, pharmaceutical and other fields.
Molecular distillation is a common chemical method used to separate and purify compounds. In the pharmaceutical industry, molecular distillation is widely used in pharmaceutical purification. This article will focus on the application of molecular distillation in pharmaceutical purification and provide some specific examples.
Laboratory vacuum distillation equipment has undergone significant advancements in recent years, driven by the need for higher efficiency, improved safety, and enhanced user experience.
