Sunflower oil machine
    Sunflower oil machine is generally divided into oil press machine and solvent extraction oil machine
    Pressing method of sunflower oil machine
    Pressing method, also known as "physical pressing method", is to use external force to squeeze out the oil in the oil. Other chemical solvents are not applicable, which avoids the residual of organic solvents in the oil.
    The squeezed production process retains the active ingredients in sunflower seeds to the greatest extent-polyunsaturated fatty acids and proteins, dietary fiber, vitamins, trace elements and other nutrients that are beneficial to the human body. It is more suitable for special supplements for the human body. health care.
    Solvent extraction method for sunflower oil machine
    The oil produced by the solvent extraction process is also called leaching oil. It is the extraction of oil with organic solvents (such as gasoline, n-hexane, etc.). The extraction method is to use solvent oil (light gasoline No. 6) to soak the raw oil and extract it. An oil making process in which oil is extracted. The "oil" originally leached is a mixture of organic solvents and oils. It cannot be eaten. It must be processed after a series of refining processes (chemical treatments such as dewaxing, degumming, dehydration, deodorization, deacidification, decolorization) The oil is generally light in color, and the initial natural gas taste in the material seeds is light or no obvious odor.      The extraction process can almost extract all the oil in the oil, and the economic benefits are very high. It is the most popular processing method in the modern oil industry.
    Pressing process of sunflower oil machine, raw material screening → cleaning impurities → hulling → crushing → steaming → pressing → pressing crude oil → coarse filtration → fine filtration → low temperature crystallization and crystal growth → low temperature filtration → sunflower oil
    Advantages: It retains almost all the nutrients in sunflower oil, has a refreshing and non-greasy taste, and is rich in polyunsaturated fatty acids.
    Disadvantages: low oil output rate and relatively high cost
    Extraction process of sunflower oil machine; pre-pressed cake --- solvent extraction --- separation-sunflower oil --- derefining
    Advantages: very high oil yield, low cost and higher economic benefits. The most popular processing method in modern grease industry.
    Disadvantages: Destroyed a part of the nutritional components, and there was a trace of residual organic solvents
