Waxes are present in many oils, such as peanut oil, rice bran oil, sunflower oil, walnut oil, etc., and their content ranges from a few parts per million to 0.2 percent.
Sunflower oil content is high, in 38% ~ 45%, after taking the oil meal protein as high as 38% ~ 42%, suitable for the use of pre-pressing - extraction method of oil. This process can increase the oil yield of the product and also increase the production capacity of the extraction equipment. However, extraction method produces crude oil, which contains various impurities, such as water, free fatty acids, pigments, proteins and so on.
Dewaxing
Sunflower oil in the refining process, dewaxing is the last step, The
sunflower oil dewaxing process causes the wax to crystallize and then separate the oil and wax by filtering to obtain pure sunflower oil, due to the sunflower shell contains wax, in the extraction of sunflower oil, although the shell will be processed, but in order to improve the rate of oil, sunflower kernel will be mixed with a small amount of shell, which is to lead to get a small amount of wax in the crude oil, wax is a weak hydrophilic lipophilic compounds, in the low-temperature conditions will be precipitated from the oil.

Sunflower oil refining dewaxing process is relatively mature, but the effect of oil dewaxing in the market is not the same, which is closely related to the choice of machinery and equipment. Therefore, oil plant in the choice, we must cooperate with the strength and high market share of machinery and equipment manufacturers, not only can achieve the desired dewaxing effect, but also because of the large manufacturers, whether it is in the quality of machinery and equipment, program or after-sales service are guaranteed, to help oil plant high-quality economic development!
