A mixing chamber for mixing a variety of dry ingredients with a liquid is disclosed. The mixing chamber has an accumulation chamber that evenly distributes ingredients as they pass a liquid spray nozzle, resulting in uniform hydration. The liquid may be sprayed at a variety of pressures to achieve varying levels of granule hydration to permit the manufacture of dough, batter, or other compositions. Even dry ingredients which are generally slow to absorb moisture may be rapidly and evenly hydrated without an excess of liquid. Process parameters, such as volume flow rate of the dry ingredients, can also be varied.
