Abstract: A dispensing apparatus dispenses a precisely metered quantity of pellets or granular material from a hopper to a vessel. The hopper which holds the pellets or granular material has a conical bottom portion which terminates in a bottom opening that is in constant communication with a conveyor tube which leads to the vessel. The conveyor tube preferably extends horizontally below the hopper and is in communication with a bottom opening in the hopper. A venturi driven by compressed air is provided in the conveyor tube for creating a vacuum which carries the pellets or granular material from the hopper to the vessel. The pressure of the compressed air entering the venturi is precisely regulated so as to precisely control the amount of pellets or granulated material moved from the hopper to the vessel. Alternatively, a controller can be provided for regulating several conveyor tubes, each to feed a different type of pellet or granular material into the vessel.
