Screw oil press

Screw press is a prefabricated welding frame with closed lining. In the frame there are bearing supports of the screw shaft and units for mounting of the loading case, the pressing cage, the bath for oil drainage, the channel for the oilcake exit. The transmission of torque from the motor is carried out by means of a V-belt transmission, and from the gearbox to the screw shaft – by a special cam-disc coupling. During the operation of oil press, the prepared material is fed by a screw shaft into the pressing cage through the feeder and the loading case, where the oil is extracted. The pressed oil flows through the slots of the pressing slats into the bath, from which it is fed for further processing. The pressed material (oilcake) comes out through the annular gap between the sleeve and the cone of the screw shaft.

Oil presses operate in a continuous mode of full mechanical load, so it is very important that all parts of the press that are in contact with raw materials (screws, pressing cages and slats, etc.) are durable. To achieve maximum wear resistance, our company carries out heat treatment of all these parts, which significantly increases their service life and reduces customer costs for the purchase of spare parts.

Each press is completed with gearboxes of the European production, frequency converters for regulation of rotation frequency of the electric motor according to requirements of individual production.

Our company produces oil presses in two variants:

– for preliminary pressing (forpress);

– for final oil pressing (expeller).
