ABSTRACT:
A feeder apparatus for feeding dry, granular material from a barrel into a hopper and from the hopper into a mixing tank has a plunger which accepts small predetermined amounts of material through an opening in the bottom of the hopper, slides to a second position where the material is released into the mixing tank. The plunger is solenoid actuated and has an electronic timing circuit for actuation in a predetermined time sequence for varying the amount of material deposited in the mixing tank.
