What is Subcritical Water Extractor
Sub-critical fluid extraction (Subcritical Water Extractor) is a technology that utilizes a subcritical fluid as an extractant. Sub-critical fluid is a substance that exists at a temperature higher than its boiling point but lower than its critical temperature, and at a pressure lower than its critical pressure, sub-critical fluid exists in liquid state under a certain pressure, and its mass transfer rate is fast, and its extraction capacity is strong.Based on the principle of similar organic solubility, the fat-soluble components in the solid material are transferred to the liquid extractant through the molecular diffusion process between the extracted material and the extractant in the immersion process. Finally, the extractant is separated from the target product through the process of decompression evaporation, so as to obtain the target product.
This technique has the advantages of high efficiency, environmental protection, energy saving, and does not use organic solvents, so it is considered a green extraction technique. Subcritical extraction technology has been widely used in the fields of chemical industry, food, medicine, etc., mainly used for the extraction of pigments, oils and fats, and precious oils.

Advantages of Subcritical Water Extractor
Improved Solubility
At higher temperatures, water’s surface tension decreases, making it an excellent solvent for extracting a wide range of compounds, including those that are harder to dissolve (like lipophilic substances).
Enhanced Mass Transfer
Under subcritical conditions, mass transfer is significantly improved. The higher temperatures increase diffusion rates and reduce the viscosity of the solvent layer around particles, allowing the water to penetrate deeply into the material.
Reduced Use of Hazardous Solvents
Subcritical water extraction replaces traditional organic solvents with water, reducing the environmental impact and creating a safer, more sustainable extraction method.
process of Subcritical Water Extractor
Good quality granules or cakes after extraction. The subcritical fluid extraction machine keeps the original heat-sensitive material not damaged, and invariance rate of water-soluble protein can reach up to 95%.
Low solvent addition and environment protection. Advanced subcritical fluid extraction technology has low solvent consumption of less than 10kg per ton material. There is no addition of steam but only 90℃ hot water to obtain 70% energy saving, and total environmental protective project.
Room temperature extraction and low temperature (less than 40℃) desolventizing. This low production cost subcritical extraction machine adopts room temperature extraction and low temperature desolventizing extraction, having no destroy of hot-sensitive material inside extracted oil. Subcritical fluid extraction technology is an ideal process for precious shelf oil and natural pigment extraction.
