ABSTRACT:
An oilseed press of the present invention is adapted to extract oil from oilseeds. The oilseed press includes a base plate having a raised surface with straight and tapered edges. A cylindrical sleeve also has a tapered edge at one end and is adapted to slide over the raised portion of the base plate forming a tight fit between the tapered portions and forming a gap between the straight edge and the sleeve. A plunger is adapted to slide within the sleeve. By applying pressure to the plunger the oilseeds are crushed between the plunger and the raised surface of the base plate. Oil collects within the gap and exits the gap through a notch formed in the tapered surface where it collects in a well. The pressure is applied by a linear actuator having a rubber bumper assembly. When the clutch of the linear actuator begins to slip, the bumper assembly maintains a high pressure on the plunger.
