Abstract
A controls stage, a hopper stage, and a pneumatic stage are arranged to govern the movement of particulate additives from a hopper through a receptacle that communicates with a delivery tube with the particles exiting the delivery tube via an outlet and contacting products or commodities such as food products. Embodiments include those wherein the use of air flow through the delivery tube is responsible for ushering particulate additives out of the delivery tube, with or without a secondary air flow to facilitate movement of particulate additives into the delivery tube, and a notched disc controlling the opening and closing of a valve to allow or restrict particulates from passing, wherein the size and quantity of notches affects the frequency at which particulate additives move from the hopper into the delivery tube.
