A reservoir (1) contains a large amount of citrus fruits to be pressed which must successively leave the reservoir through an opening (6). In order to convey the citrus fruits a central part of the bottom surface of the reservoir, which otherwise steeply climbs up to the walls of the reservoir, is formed by several adjacent, mutually parallel rolls (2) that have a non circular cross-section with a circunference formed of three convex circumferential parts (7) and that are rotatively driven in the same direction and with the same angular position, so that the citrus fruits lying on the rolls (2) are conveyed towards the outlet opening (6). Since the citrus fruits that lie above each other in several layers within the reservoir tend to form bridges, because of the structure of the surface of their rinds, the whole amount of citrus fruits stored in the reservoir (1) is in addition moved by rammers (8) capable of moving up and down among the fruits. The rammers (8) project upwardly through the steep bottom of the reservoir adjacent to the row of rolls. Three rammers (8) are secured to a rail (9) that extends below the bottom surface of the reservoir, on each side of the row of rolls. Both rails (9) are mutually linked at one of their ends by a pivot (10). Rotary cams (11) located below each rail, on the axis of one of the driven rolls (2), make the rails (9) and the rammers (8) move up and own. |
