Pre-pressing

Depending on the type of oilseed, we need to use different methods of oil press: Oil press is divided into pre-pressing and pressing (cold pressing, hot pressing). Here we mainly introduce oil pre-press section.

Oil Pre-pressing can extract about 70% of the oil in the oilseeds (the oil content of the extracted cake/meal is required to be less than 20%). Whether pre-pressing is required is related to the oil content of the oil seeds.

1. Oil Pre-press: oil content ≥20%

    Oil seeds: sunflower seeds, peanuts, rapeseed, cottonseed, etc.

2. Oil Solvent extraction: oil content <20%

    Oil seeds: soybeans, rice bran, etc.

The related equipment for Oil Pre-pressed: mainly oil press (palm fruit oil press is different from conventional oil presses)

Oil pre-pressing technology is a traditional processing technology for high oil content. Our pre-pressing technology has the following advantages:

1. Able to process a variety of oils: peanuts, rapeseed, cottonseed, sunflower seeds, and sesame, etc;

2. According to customers' requirements, the expansion process can be used to save energy and obtain high-quality oil;

3. Multi-stage filtration for pre-pressed oil;

4. Strong adaptability to raw material quality.
