Screw-feeder dosage unit particularly for the dosage of solid or powdered products, which includes a frame which supports a hopper in which the product to be dosed is introduced, and an extractor for the product which is driven by a gearmotor. The unit includes a stirrer which is suspended inside the hopper, above the extractor, and is driven by an actuation means, the stirrer producing vibrations which allow separation of the product from the walls of the hopper for the descent of the product toward the extractor.
