Sunflower Seed Temperature-controlled Filtering All-in-one Oil Press

Low-temperature pressing sunflower oil and refining treatment

Low temperature pressed sunflower oil is characterized by its light color, low phospholipid content, and can be deacidified without alkali refining, white clay decolorization, and high temperature deodorization, thus avoiding the introduction of extra ingredients into the oil and trans fatty acids formed by high temperature deodorization. Low temperature pressed oil does not add any antioxidants, which meets the requirements of green, environmental protection and nutrition, and the extracted vegetable oil keeps its original color, natural taste and natural odor, especially the natural inclusions such as unsaturated fatty acids, vitamin E and trace elements can be retained. The wax content in the sunflower seed oil obtained by using low temperature pressing technology is high, if not removed, the oil will appear turbid at low temperature, which affects the beauty of the oil.

The main production process is as follows：

After the selected sunflower seeds are pressed at low temperature, the pressed oil is pumped into oil filter. After the filtered oil is de-gummed and dehydrated by refining, dewaxing treatment is required. In the process of crystallization, the cooling speed of is too fast, and the crystal particles precipitated are often very small and difficult to filter, while controlling the temperature and time of crystallization, large and solid crystals can be obtained, which are easy to separate wax and oil by filtration. Therefore, the wax content in sunflower oil is taken as the index, and the stirring speed, crystal raising time and crystal raising temperature are selected as factors to optimize the dewaxing process of sunflower oil.

The fatty acids in low temperature pressing & refined sunflower oil mainly consist of palmitic acid, stearic acid, oleic acid and linoleic acid, with unsaturated fatty acid content of 90.26%, of which linoleic acid has the highest content of 64.62%, followed by oleic acid, an essential fatty acid. And because the pressing process is under medium and low temperature conditions, the trans acid does not change basically before and after refining, and the oil structure is not destroyed.
