<p>Apparatus (1) for depositing edible mass, comprising an elongated trough (2) with an inside chamber (3) and a pump roller (4) housed in a channel (5) at the bottom (6) of the trough (2). A row of deposit openings (7) are arranged along the bottom (6). The pump roller (4) comprises a single, central shaft (8) having a succession of disc-shaped rotors (9) defining the outer periphery (10) of the pump roller (4). The rotors (9) are formed as wave-shaped displacers (11) arranged in a succession of arc-shaped channels (12). A closure plate (13) is arranged longitudinally in a groove (14) in the channel (5) and radially to the shaft (8). The plate (13) comprises a succession of notches (15) into which the rotors (9) engage, so that the plate (13) is given a reciprocal movement by the rotation of the pump roller (4). The inside chamber (3) extends as a vertical channel (16) from the top of the trough (2) and down to an upper part (17) of the pump roller periphery. So the mass is free to flow downwards and then effectively fills radially in between the wave-shaped displacers 11 and into the arc-shaped chambers 12 of the pump roller 4.The wave-shaped displacers 11 of the pump roller 4 effectively take the full action of a pump, which continuously transports the mass on to the openings 7 at the bottom of the trough 2.Mass with high contents of inclusions may then enter into the roller pump right away and very smoothly, still bringing with it the inclusions into the pump cavities.</p> |
