Abstract: Particulate material to be aromatized is fed to the circumferentially grooved surface of a rotating wheel which carries said material from the in-feed to the discharge stage of its rotation during which travel the material is injected with a predetermined quantity of an aroma-enriched carrier liquid.

Abstract: A housing for receiving a working amount of dough, a shaft mounted on a central axis within the housing, a first wall, curved on a radius from the central axis and having a plurality of apertures formed through it. A feed cylinder mounted on the shaft, the cylinder having a surface eccentric about the central axis with the highest point of eccentricity approximately equal to but less than that of the radius, so that as it is rotated it traverses the apertures with the highest eccentricity in intimate association with them, for separating portions of dough from the working amount. For dough of heavy consistency, spring means is included for urging touching contact between the cylinder and the curved wall, and a cut-off edge may be provided on the cylinder at its highest point of eccentricity.

Abstract: Envelopes are opened by standing each envelope on an edge thereof in a guide channel and moving the envelope on edge along the channel into and through a cutting zone where one or more knives being rotated on a flywheel rotor continually move past an anvil and slice off a succession of narrow elongate segments of the border of the envelope. The segments are thrown from the cutter and fall by gravity into a collecting receptacle. Each knife has a cutting edge formed with at least one leading point and with cutting edge portions trailing from the point. Each segment is sliced off by first puncturing the envelope at a point in its border and then slicing it from that point across and along its edge.
