Prepressing adopts the screw press machine, screw press machine has characters of continuous processing, dynamic press time short, high oil yield and low the labor intensity.
Big capacity sunflower oil pressing machine is for the cooking oil industry company usage or for the huge capacity sunflower oil processing line. It has the features of high working efficient and stable. And the big capacity sunflower oil extraction machine cost is the highest.
The main part of the screw press is pressing chamber, pressing chamber is in pressing cage with pressing cage and screw axis of rotation.
Its working process is the use of screw axis helical lead to narrow or the root circle diameter increases gradually, make the pressing chamber volume shrinking and pressing effect, the extract oil extrusion flow from a crack in the press cage, at the same time pressing the residue into crumbs bread slices, from press shaft end continuously flow out.
