Description
Technical Parameters
Short path molecular distillation is a special distillation technology, which can separate different components in the mixture in a very short time and at a very low temperature in a vacuum environment. The principle of this technology is based on the fact that different substances have different boiling points at the same pressure. In short-distance molecular equipment, the mixture is heated to a very high temperature and then enters a high vacuum environment. In vacuum, the different components in the mixture will evaporate at a very fast speed, because the components with low boiling point can evaporate in a very short time, while the components with high boiling point can evaporate slowly in a longer time.
Because the evaporation time is very short, this technology is called short-distance molecular distillation. It can effectively separate different components, and at the same time avoid the problems of product decomposition and deterioration caused by long-term high-temperature operation.
Short-range molecular equipment usually consists of heating furnace, condenser, vacuum pump and collecting bottle. The heating furnace can be heated to a very high temperature, the condenser can quickly cool the vapor and condense it into liquid, the vacuum pump can maintain the vacuum state in the equipment, and the collecting bottle can collect the evaporated liquid with different components.

Product Introduction
The heating furnace is one of the core components of short-range molecular equipment, and its main function is to provide stable and accurate thermal energy to achieve the required evaporation temperature of the material. Heating furnaces usually use resistance or quartz tube heating methods, which can quickly and uniformly raise the temperature, ensuring that the mixture can evaporate quickly and stably during the heating process.
The heating furnace is designed with a sample compartment inside, which is used to place the materials to be separated and ensure that they are not disturbed by the external environment during the heating process. At the same time, the heating furnace is also equipped with a temperature control system to accurately control the heating temperature and avoid local overheating or insufficient temperature. This precise temperature control is crucial for maintaining the thermal sensitivity of the material and ensuring separation efficiency.
The condenser is another key component in molecular equipment, whose main function is to rapidly cool and condense the steam generated by the evaporator into liquid. The design of the condenser directly affects the separation purity and yield of the product, so the selection of its structure and materials is particularly important.
Condensers are usually composed of tube or plate structures, which can provide a larger heat exchange area and improve cooling efficiency. In short-range molecular equipment, the condenser usually uses efficient cooling media, such as circulating water or refrigerant, to ensure that steam can quickly condense into liquid. In addition, the shape of the condenser and the gap with the heating surface also need to be designed reasonably to optimize the heat exchange effect and prevent droplet splashing and entrainment.
The splash guard is an essential component of short-range molecular equipment, whose main function is to prevent liquid droplets carried by the steam flow from splashing onto the condenser or other components. If these droplets are not removed in time, they may contaminate the product and reduce the separation purity.
Splash prevention devices are usually installed between or behind the rotor scraper film, which can effectively intercept and guide splashing droplets back to the heating surface for evaporation. Common splash prevention devices include mist separators and deflectors, and the design of these devices needs to fully consider the principles of fluid mechanics and the requirements of separation efficiency.
The built-in condenser is one of the special designs in short-range molecular distillation equipment, which is located at the center of the evaporator and closely matches with the rotor. The main function of the built-in condenser is to quickly condense light molecules escaping from the heating surface into liquid and collect it.
The design of the built-in condenser needs to fully consider factors such as distance and angle from the evaporation surface to ensure that light molecules can condense quickly and efficiently. At the same time, the built-in condenser also needs to have good sealing and corrosion resistance to cope with the effects of high temperatures and corrosive substances.
The collection device is the last component of short-range molecular equipment, and its main function is to collect the condensed liquid product. The design of the collection device needs to fully consider the requirements of product purity and collection efficiency.
The collection device is usually located at the bottom or side of the evaporator and equipped with appropriate discharge pipes and valves to control the outflow of the product. In order to avoid oxidation or contamination caused by contact between the product and air, the collection device is usually equipped with an inert gas protection device inside. In addition, in order to obtain products of different qualities and improve separation purity, the collection device can also be designed as a multi-stage collection system to separate different fractionation components.

Applications
The application of short path molecular distillation in renewable resources is mainly reflected in the production process of biodiesel.
In the process of biodiesel production, short-range molecular distillation can be used to purify biomass particles to prepare biomass fuel. This short-distance molecular distillation technology can efficiently separate and purify biomass and improve the yield and quality of biodiesel.
In addition to the production of biodiesel, short-range molecular distillation unit can also be used in other renewable resources, such as biomass power generation, biomass thermal power generation, biomass heating and other fields. It can effectively treat and utilize biomass and improve energy utilization efficiency.
In addition, molecular distillation also has broad prospects in the application of renewable materials. For example, short-range molecular distillation technology can be used to separate and extract natural polymer materials, biodegradable plastics and other renewable materials, improve the performance and quality of materials, and promote the development and application of renewable materials.
About biodiesel
Biodiesel is a renewable and environmentally friendly fuel derived from biological sources, primarily vegetable oils, animal fats, or waste greases. It serves as a direct substitute for or blend with traditional diesel fuel in compression-ignition engines, offering significant benefits for reducing greenhouse gas emissions and dependence on fossil fuels.
The production process of biodiesel typically involves a chemical reaction called transesterification, where triglycerides from the feedstock are converted into fatty acid methyl esters (FAMEs) or ethyl esters, using methanol or ethanol and a catalyst. This results in a clean-burning fuel that can be used in existing diesel engines with minimal modifications, making it an attractive alternative for immediate adoption.
One of the key advantages of biodiesel is its biodegradability and relatively low toxicity, which reduces the environmental impact in case of spills. Additionally, it contributes to energy security by utilizing domestically produced resources, often from agricultural waste or by-products, thus creating economic opportunities in rural areas. Furthermore, biodiesel production can help in managing waste oils and fats, diverting them from landfills and waterways.
However, challenges such as feedstock competition with food production, the energy balance of production processes, and the cost of raw materials remain areas of concern. Although, ongoing research and technological advancements are focused on overcoming these hurdles, making biodiesel a more viable and sustainable energy option for the future.

Short path molecular distillation, often abbreviated as SPMD, is an advanced separation technique employed in the chemical, pharmaceutical, food, and cosmetics industries. This process leverages the differences in molecular volatility under reduced pressure conditions to purify and isolate high-value compounds.
In SPMD, the feed material is heated to a temperature below its thermal degradation point, converting it into a vapor phase. This vapor then travels through a short distance-typically less than one meter-to the condenser, minimizing the residence time and reducing the likelihood of thermal decomposition. The short path ensures rapid condensation, allowing for the effective separation of components with close boiling points, even those with high boiling points or those that are heat-sensitive.
A key feature of SPMD is the use of a high vacuum, which significantly lowers the boiling point of the compounds and enhances the separation efficiency. This vacuum environment also helps eliminate oxygen, thereby preserving the quality and purity of the final product.
Moreover, SPMD systems are often equipped with wiped film evaporators, which enhance surface area for better heat transfer and vaporization. This design further supports the gentle handling of the materials, making it ideal for processing delicate compounds.
