corn oil extraction machine

Subcritical low-temperature extraction technology can obtain high-quality corn germ oil in one step, with an oil yield of more than 90%. In comparison, the oil yield of traditional pressing process is lower. The process has made a breakthrough in reducing acidity, which can effectively improve the quality of oil products. A low-temperature, low-pressure and highly efficient extraction and separation technology that does not require excessive heating and does not damage heat-sensitive components in the material, thus saving energy. The technology is characterized by high efficiency, safety and environmental protection, and is a superior alternative to traditional extraction methods.

The process flow of vegetable oils and fats produced by subcritical low temperature extraction of corn germ is as follows:

Cleaning: The corn germ is first cleaned to remove impurities and impurities.
Drying/softening: The cleaned corn germ is dried or softened to make it reach the state suitable for extraction.
Rolling: The corn germ is pressed into thin slices through a rolling machine to facilitate the subsequent extraction process.
Steaming and stir-frying: the germ after rolling is wetted with water, heated and stir-fried and dried to form cooked germ.
Subcritical low-temperature extraction: the use of subcritical fluid as an extractant, under low temperature conditions for countercurrent extraction of cooked embryo. The subcritical fluid dissolves the fat-soluble components under a certain pressure and separates out the oil through evaporation under reduced pressure.
Separation and Concentration: The solvent in the extracted liquid undergoes an evaporation process, which vaporizes the solvent and separates it from the extracted target components to obtain pure oil and grease.

Advantages of this process include:

Quality-preserving extraction: extraction under low-temperature conditions avoids the destruction of heat-sensitive components at high temperatures and ensures the quality of the oils and fats.
High-efficiency extraction: subcritical low-temperature extraction technology can efficiently extract fats and oils from materials with high extraction rate.
Environmental protection and energy saving: low-temperature extraction reduces energy consumption, and continuous extraction, separation and concentration in the fully closed pipeline reduces environmental pollution.
Through the above process, high quality vegetable oils and fats can be effectively extracted from corn germ.
