What are the advantages of using supercritical extraction technique to extract sesame oil?

  Supercritical extraction is a technique that uses supercritical fluids, such as carbon dioxide, as solvents to extract desired compounds from a variety of materials, including plant matter. This technique has several advantages over traditional extraction methods, such as steam distillation and solvent extraction. Firstly, supercritical extraction is a more efficient method of extracting desired compounds from materials. Supercritical fluids have unique properties that make them better solvents than traditional solvents. Supercritical fluids have high diffusivity, low viscosity, and high density, which allows them to penetrate materials more deeply and extract more compounds than traditional solvents. Secondly, supercritical extraction is a more environmentally friendly method of extraction. Unlike traditional solvents, supercritical fluids are non-toxic, non-flammable, and do not leave any harmful residues behind. This makes them safer for both the environment and the workers wh...

  Automatic supercritical CO2 equipment has the following advantages: Efficiency: Automatic supercritical CO2 equipment can complete a large amount of chemical reactions in a short period of time. As a solvent, supercritical CO2 has high permeability and diffusion, which can improve reaction rate and efficiency. Environmental friendliness: Using supercritical CO2 as a reaction medium can reduce environmental pollution because it is a non-toxic, tasteless, and colorless gas that does not affect the environment. Additionally, using supercritical CO2 can also reduce waste production. Controllability: Automatic supercritical CO2 equipment can control the rate and efficiency of chemical reactions by adjusting parameters such as temperature, pressure, flow rate, and reaction time, allowing for more precise reaction conditions. Versatility: Supercritical CO2 can be used as a solvent for many different types of chemical reactions, including organic synthesis, chemical separation, solid ext...

Supercritical Fluid Extraction Technology

Supercritical fluid extraction is the world's most advanced physical extraction technology, referred to as SFE (supercritical fluid extraction). At lower temperatures, when the gas pressure is continuously increased, the gas is converted into a liquid. When the pressure increases, the volume of the liquid increases. There is always a critical temperature (Tc) and critical pressure (for a particular substance). Pc), above the critical temperature and critical pressure, the material does not become liquid or gas, which is the critical point. In the range above the critical point, the matter state is between the gas and the liquid, and the fluid within this range becomes a supercritical fluid (SF). Supercritical fluids have strong penetrability similar to gases and large density and solubility similar to liquids, have good solvent properties, and can be used as solvents for extraction and separation of monomers. Supercritical fluid extraction (SFE) is a high-tech technol...
