Abstract: A mixing apparatus and method wherein the mixing apparatus includes a hopper having a port piston for periodically retracting to open a fluid port to allow a slug of gas to be quickly injected into the bottom of a hopper, which produces a mixing and blending of the materials in the hopper as the slug of gas flows upward through the materials in the hopper. The port piston periodically closes to seal the fluid port without allowing the material in the hopper to backflow, which would prevent between the port piston and a hopper sealing member from being brought into sealing engagement.
