DISC PRESS FOR THE OIL EXTRACTION FROM OILSEED

摘要

Device for oil extraction from oilseed, comprising three discs, one disc (14) with a horizontal rotation axis and two discs (1) with their rotation axes inclined to the horizontal. The discs (1, 14) have a truncated part in which are mounted half-cups (3) which together with the perforated plate (2) form a cavity for pressing the seeds. The seeds from tank (20) fill by free fall the dosing cavities of the rotary selector (19), pass through the gutter (23) and reach the half-cups (3) where they will be pressed. The mechanical pressing is performed in a first step by driving the half-cups (3) with the outer punches (4) and then by the radial movement of the inner punches (11), which reciprocate inside the outer punches (4) driven by radial cam (9). The outer punches (4) are radially arranged on two rotating punch-carrying wheels and ensure the synchronous rotation of the outer discs (1) and the inner disc (14). Starting with the seed loading area, the half-cups (3) are joined due to the inclination of the rotational axes of the discs (1, 14) and then, continuing the rotation movement after pressing, their separation takes place to release the pellets. In the area where the separation of the half-cups (3) begins, the plate (2) has no holes and ensures the pellets slide on the inclined trough (17) to the pellet tank (16). The electrical resistors (15) on the outer discs (1) provide a constant extraction temperature.
