Abstract: This invention relates to a screw feeder adapted to be used in relation with a combination weigher, where the combination weigher comprises a dispersion unit, and a plurality of trenches surrounding the dispersion unit, where each of the plurality of trenches comprise an infeed end and a releasing end where each of the trenches and have a circular sector like shaped bottom portion, where the dispersion unit is adapted to radially disperse food products into the trenches at their receiving ends, where at each trench the received food product is advanced by said screw feeder towards the releasing end, where said screw feeder is made of a material being softer than the material of the trenches and is designed such that it has a polygon cross sectional shape having three or more edges.

Abstract: A mounting device for mounting a screw feeder to a combination weigher allows an operator to mount a screw feeder to a motor unit assembly of a combination weigher by placing the screw feeder to the motor unit assembly such that the actual rotation of the motor ensures the actual mounting of the screw feeder to the motor unit.

Abstract: A combination weigher includes: a dispersion unit adapted to radially disperse food products dropped in from above and onto the dispersion unit; a plurality of V-shaped like guide structures extending radially away from a center of the dispersion unit and arranged such that a narrower end of the V-shaped like guide structures face a center point of the dispersion unit; a plurality of hoppers associated to each of the trenches arranged below the outfeed ends of the trenches; and a control unit; and screw feeders arranged in each of the trenches operated by the control unit. The space between adjacent V-shaped like guide structures at a distance R1 defines a buffer zone for radially dispersed food products from the dispersion unit. The screw feeders in the adjacent trenches have opposite orientation and rotate in opposite directions such that upper part of the screw feeders are rotating away from each other.

Abstract: A combination weigher including a dispersion unit adapted to radially disperse product material dropped in from above onto the dispersion unit, plurality of weighing hoppers, plurality of conveyor units arranged around and below a periphery of the dispersion unit. The conveyor units include troughs having infeed ends positioned below the dispersion units and outfeed ends positioned above the weighing hoppers, and spiral shaped members extending from the infeed ends towards the outfeed ends. Spiral shaped members being operable connected to an operation unit for operating a rotational movement of the spiral shaped members conveying the product material from the infeed ends towards the outfeed ends into the weighing hoppers. Conical shaped members are arranged within the spiral shaped members.
