Abstract: The invention is an apparatus for loading and unloading pellets into a trailer. Conduits are positioned with at least one opening configured to direct flow toward a central longitudinal axis of the interior region. A blower is connected to an input port, and a suction device is connected to an output port to cause a flow of moving air so that pellets within the interior region are carried with the flow toward the central longitudinal axis, the collector and an output port. A pellet loading pipe has a plurality of spaced openings and deflection plates upstream of each opening. Pellets in the pipe are deflected from the openings until a clog develops downstream, at which time the pellets will exit an opening adjacent the clog until it clogs, and continuing successively until the longitudinal spaced opening proximate the loading port becomes clogged and the interior region is substantially full.
