Liquid beverage concentrate mixing beverage dispenser and method

A mixing drink dispenser comprising:

• a mixing chamber for receipt of mixing liquid drink concentrate with water for mixing together into a beverage, said mixing chamber having
• an upper cylindrical section with
• a water inlet directed for flow of streaming water tangentially against an interior surface of the cylindrical section at a first level, and
• a concentrate inlet directed for flow of streaming concentrate generally perpendicularly against the interior surface at a second level beneath the first level;
• a source of mixing water connected with the water inlet, and
• a concentrate hopper for holding liquid drink concentrate connected with a drain hole connected to the concentrate inlet,
• said concentrate inlet being an open end of an elongate concentrate inlet tube located within the mixing chamber and extending from one side of the upper cylindrical section toward a side opposite the one side, and
• said inlet tube extending substantially across the mixing chamber to the open end, said open end being located directly opposite a concentrate inlet closure at another side of the upper cylindrical section diametrically opposite the sealed tube opening at the one side.

A method of mixing and dispensing a mixed drink with a mixing drink dispenser, comprising the steps of:

• injecting mixing water from a source of water through a tangentially directed water inlet in a cylindrical side of an upper cylindrical section of a mixing chamber against and along an interior surface of the cylindrical section at a first level to create a spiraling flow of streaming water around the interior cylindrical surface;
• and
• injecting liquid concentrate from a concentrate hopper though a concentrate inlet in a cylindrical side of the mixing chamber directed for flow of streaming concentrate generally radially against the interior surface at a second level beneath the first level;
• and
• mixing the water with the concentrate along the interior surface as the spiraling flow of streaming water moves downwardly along the interior surface from the first level to the second level to mix with the concentrate on the interior surface.
