  • Patent number: 11503956
    Abstract: A grinder-doser may include: grinding members configured to receive and grind coffee beans and configured to deliver ground coffee into a dispensing conduit; a compacting member including a dispensing opening aligned with the dispensing conduit; a slide guide; and a sliding block configured to slide along the slide guide for selectively superimposing a first or second opening to the dispensing opening, allowing the ground coffee to move from the dispensing conduit to the dispensing opening via the first or second opening. The first opening may be reversibly closed by a closure element. The closure element may include a flexible sheet. The closure element may be configured to allow the ground coffee to move from the dispensing conduit to the dispensing opening as a thrust limit value exerted by the ground coffee on the closure element is exceeded. Thrust exerted by the ground coffee may cause the closure element to bend.

  • Patent number: 9384890
    Abstract: A powder-filling system capable of filling a container with powder at an approximately uniform filling density has: a hopper having an opening removably and hermetically closably attached to the container, the hopper communicating with the container at the opening for supplying powder to a container; a powder supplier for supplying powder to the hopper; a gas supplier for repeatedly supplying compressed gas in a pulsed form to the hopper, with the hopper hermetically closably attached to the container; and a sieve member provided at the opening and having a smaller openings in a region near a side wall of the hopper than in its central region. The smaller openings in the region near the side wall of the hopper where the powder more easily falls from the hopper into the container impedes the fall of the powder in that region and improves the overall uniformity in the filling density.

  • Patent number: 4576209
    Abstract: A method and apparatus for delivering a predetermined amount of material into a predetermined position on each of a series of moving trays while avoiding spillage of the product onto other portions of the trays. A conveyor lifts the material from a supply bin and deposits the material onto a shaker pan. The shaker pan delivers the material in an even flow on to a rotating turntable having a plurality of radially extending gutters thereon. The turntable directs the material to flow along the gutters and into a plurality of hoppers disposed at the periphery of the turntable. The hoppers are rocked to distribute the product evenly within each hopper. Once a hopper is full, any excess material falls onto a drip tray which returns the material back to the supply bin. The filled hoppers are rotated above the trays, which are moving on a conveyor, and release the material onto a predetermined area of the trays by means of funnels mounted adjacent to each hopper.

    Abstract: A guide cylinder with its axis directed in the upper and lower directions is provided on the bottom of a hopper. In the guide cylinder are allowed to pass a plurality of measuring containers supported by an endless conveyor which is moving upwardly from the bottom of the hopper, so that bulk foods in the hopper are scooped up into the measuring containers. While the measuring container is still over the hopper, excess bulk foods are caused to fall onto the hopper by way of a suitable shaking operation. Thereafter, the bulk foods are conveyed out of the hopper by the conveyor, and exhausted at an exhausting station by turning the measuring container upside down. The distance between the measuring containers provided on the endless conveyor is made smaller than the length of the guide cylinder so that at least one of the measuring containers is always present in said guide cylinder. This enables the measuring containers to further serve as a bottom covering of the hopper.
