A granular coating conveyor system for coating granular particles carried in compartments along a tubular conveyor member. Coating fluid is fed over the granular particles through radial nozzles located inside a co-axial rotating blender with tubular member upstream discharge port and tubular member downstream return ingress port for the granular particles. The blender is a drum having a helicoidal spiral screw integrally mounted to an interior peripheral wall face of the drum and extending therealong radially outwardly of the tubular member mixing in the drum in tumbling fashion the granular particles with coating fluid and guiding same therealong, so as to dynamically form a kidney shape mass of granular particles.

This invention quickly supplies a predetermined amount of powder from a hopper to a recoater. A powder supply apparatus includes, as its feature, a hopper, a powder spreader, a powder replenisher, and a pivoting unit. The hopper of the powder supply apparatus stores a powder. The powder spreader spreads the powder on a shaping surface. The powder replenisher of the powder supply apparatus is provided between the hopper and the powder spreader, and replenishes the powder spreader with a predetermined amount of powder. The pivoting unit of the powder supply apparatus causes the powder replenisher to pivot.

A combine harvester including a grain tank having an auger trough in which a screw conveyor of an unloading system is disposed. The screw conveyor is operable to define an upturning side and a downturning side. The grain tank includes a floor section that covers the upturning side to prevent back flow and the formation of a stagnation zone in the vicinity thereof.

A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.
