The device includes a holding device provided with an array of feeder positions arranged adjacently in a plane, a collection frame arranged below the holding device including a series of collection trays for capturing discharged solid substances from the feeder units and each collection tray includes an output opening, and a packing unit arranged below the collection frame for collecting the captured solid substances from the output opening of a tray and packing the substances. The collection frame and the holding device are movable with respect to each other. The collection trays have an elongated shape with a longitudinal direction which extends substantially parallel to the plane and over a length of at least two of the feeder positions.
