(The sunflower seed oil yield > 25%. So it is better to pre-press first. And then send the raw embryos to the extractor.)
Raw material → cleaning screen → stone separator → sheller → flaker → cooker → pre-press → crude oil
The press oil has good natural flavor and smell,and color with the high purity. People can eat directly.
The crude oil from pre-press index:
1,moisture and volatile matter(%):≤0.20
2,insoluble impurity:≤0.20
3,acid value:≤4.0
4,peroxide value:≤7.5
5,preserve the original smell ,no strong smells
Features of our pretreatment technology:
1. Different combinations of process can process various oil plants in one workshop.
2. Use special intensified pretreatment technology for aroma sunflower oil to make it more aroma.
3. Adopt advanced and reliable shelling technology to meet higher requirements for protein content in meal.
4. Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.
5. The new technology of shelling and low-temperature treatment can ensure high protein and least denaturation.
