Dry powder mix is mixed with water in accurate amounts on demand, the water and powder pass through an axial passage of a mixing rotor and must pass radially outward in a mixing bowl through a narrow gap to a tangential discharge opening. Demand is determined by startup and continuous operation level sensors arranged to maintain accurate and limited levels of mixed product in the freezing cylinder.
