EXTRACTION AND GRANULATION PRESS Russian patent published in 2016 - IPC B30B9/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used, in particular, for oil extraction from oilseeds with simultaneous cake granulation. Press comprises housing, working chamber with pressing element, pressed material bin with of its output opening, bin opening shutting off mechanism. Said mechanism is made in form of piston, fixed on horizontally located hydraulic cylinder rod. Press provides for liquid fraction collector, extracting and pressing matrices. Pressing element is made in form of vertical hydraulic cylinder and arranged above opening for pressing material feeding into working chamber. Extracting matrix is placed over pressing matrix and is made in form of set of plates. Upper plate has conical holes. Each of next plates has grooves with through holes for liquid fraction discharge. To prevent extracting plates deflection along their perimeter support pads are located. In one plane with support platforms stops are arranged. Plates have vertical holes for solid fraction discharge. Extracting matrix liquid fraction discharge openings are located on one line with pressing matrix openings.

EFFECT: result is reduction of press dimensions and improving its reliability.
