The sunflower oil produced by the oil plant can be divided into pressed oil and extracted oil. Pressing is a traditional process. The pressing method can retain the flavor and nutrition of the oil as much as possible, but the cake after the oil press usually has a residual oil rate of 6% to 8%. Although it has gradually decreased with the continuous improvement of the oil press technology, it still cannot avoid the waste of oil resources. Therefore, in order to ensure the quality of oil and make more full use of oil resources, the oil plant can use a combination of oil press and oil extraction. First, pre-press the sunflower seeds, extract about 80% of the oil, and then crush the oil cake to extract the remaining oil. This method can fully improve the oil yield of the oil, and the residual oil rate of the cake after extraction can reach less than 1%.
The principle of sunflower oil extraction machine is to use chemical solvents to fully contact and soak the oil, extract the oil from sunflower seed to obtain a mixed oil, and then use the different boiling points of the solvent and the oil to evaporate, condense and recover the solvent, so as to obtain the extracted crude sunflower oil.
The extracted crude oil is treated by sunflower oil refining machine such as degumming, deacidification, dehydration, decolorization, deodorization, and dewaxing to remove impurities and harmful substances in the oil, and then edible sunflower oil that meets national standards can be obtained.
When processing edible oil, the quality of the sunflower oil production machine are very important. It has an impact on the quality and output of the oil. If you want to fully extract the oil in the sunflower seeds, you must choose a reliable sunflower oil extraction machine. Here we recommend the equipment produced by Huatai Oil Machinery. Huatai Oil Machinery has 36 years of experience in the machinery and equipment industry and can independently develop and produce cooking oil machinery.
