Oilseed pretreatment & pressing machines includes the process section of cleaning, stones removal, magnetic selection, crushing, softening, flaking, drying and so on. Different oilseeds have different pretreatment process, they need different pretreatment machines.
Oilseed pretreatment & pressing machines is important section to remove impurity, regulate moisture and temperature, break oilseeds into small particles to change oilseed molecular structure,etc. Pretreatment standard is important for the following oilseeds solvent extraction process , which influences final oil quality.

Solvent extraction plant is a better way to extract oil from oil seeds, and after extracted, the oil residue rate will be only around 1%, which is suitable for the low oil content rate seeds.
Solvent Extraction is a process involving the injection of Hexane into the oil bearing cells of seeds resulting in a mix of oil and solvent, the so called miscella. The Hexane will be evaporated later from the miscella resulting in unrefined oil. By condensing the Hexane it can be recycled and used over and over again.

Refining is the process of removing the undesirable component from the substance. Vegetable oil refining plant is removing of unwanted substances from the vegetable oil and fat oil and make them valuable for use. It is carried out in four phases: first is degumming process , second is deacidifation process, third is continuous bleaching process and fourth is deodorization process.
Different raw material,the refinery process is little different.such as for peanut,soybean,cotton seed,sesame,castor,rapeseed etc,the refinery process has four steps:degumming,deacidification,decolorization and deodorization.
For corn germ,rice bran,sunflower seed,palm oil,the refinery process has five steps:degumming,deacidification,decolorization,deodorization and dewaxing(also called fractionation for palm oil).
