A fine powder is reliably dispensed from a hopper into containers on a moving conveyor belt with the assistance of a powder feed system. The hopper serves as a powder inlet that dispenses by gravity into a feed chamber that is form fitted to the sweep of a relatively slow rotating feed wheel with two spaced sets of pins. A relatively fast rotating agitator is located below the feed wheel which has a series of agitating blades that rotate between the span of the feed wheel pins, the blades in at least one embodiment resemble a J-shape. The agitator is located directly above a rotary trap chamber wheel, which has recesses that take doses of powder and dispense them into awaiting containers moving on a conveyor belt below.
