Abstract
A static mixing nozzle used with a dispenser system thoroughly mixes one or more liquids. The static mixing nozzle has an insert having a housing with a plurality of baffles arranged in a staggered and alternating pattern throughout the passage. The baffles cause turbulence which mixes the liquid. Static mixing nozzles with different numbers of baffles may be used in the dispenser system to accommodate the different types of concentrates and syrups which may be used. The insert is removable and may be formed in parts which can be easily separated and cleaned. The insert has a ridge with an outer diameter greater than that of the nozzle, thus allowing the insert to be manually removed.
Claims29
A beverage dispenser system comprising:
- a potable water source for supplying potable water;
- a concentrate container for storing a liquid;
- and
- a beverage discharge assembly including:
- a mixing block having a passage with a receiving end for receiving the liquid from the concentrate container and for receiving potable water from the potable water source, and an outlet end;
- a nozzle having a nozzle passage having a first end fluidly coupled to the outlet end of the mixing block passage and a second end at a liquid-dispensing location;
- and
- a removable insert extending into the nozzle passage and having a housing defining an insert passage and a plurality of inwardly-directed baffles, the insert having an inlet end for receiving the liquid and the potable water from the mixing block and an outlet end for providing a mixed liquid, the housing having at the outlet end an outer diameter greater than an outer diameter of the nozzle adjacent the outlet end of the insert so as to define an insert ridge extending beyond the nozzle to provide a gripping surface.
5 more elements
A discharge assembly for mixing at least one stored liquid comprising:
- a nozzle having sidewalls defining a nozzle passage and having an inlet end for receiving a liquid, and an outlet end;
- and
- a removable insert extending into the nozzle and having a housing defining an insert passage and a plurality of inwardly-directed baffles, the insert housing further having a nozzle end near the outlet end of the nozzle passage, the housing having at the nozzle end an outer diameter greater than an outer diameter of the nozzle adjacent the nozzle end of the insert so as to define an insert ridge extending beyond the nozzle to provide a gripping surface.
A discharge assembly for mixing at least one stored liquid comprising:
- a nozzle having a vertical passage and a horizontal passage integrally formed within a nozzle housing, the horizontal passage having an inlet end for receiving liquid and an outlet end, the vertical passage having a first end fluidly coupled to the outlet end of the horizontal passage and a second end at a liquid dispensing location;
- and
- a removable insert having a housing defining an insert passage and having a plurality of inwardly-directed baffles, the insert housing further having a nozzle end near the outlet end of the vertical passage, wherein the insert housing has sidewalls along the insert passage between the first and second ends of the vertical passage, wherein the baffles are perpendicular to the sidewalls and have a uniform thickness, wherein the nozzle end of the insert has a ridge that has a maximum outside diameter greater than an outside diameter of the nozzle housing to provide a gripping surface.
A discharge assembly for mixing at least one stored liquid comprising:
- a nozzle having a vertical passage and a horizontal passage integrally formed within a nozzle housing, the horizontal passage having an inlet end for receiving liquid and an outlet end, the vertical passage having a first end fluidly coupled to the outlet end of the horizontal passage and a second end at a liquid dispensing location;
- and
- a removable insert having a housing defining an insert passage and having a plurality of inwardly-directed baffles, the insert housing further having a nozzle end near the outlet end of the vertical passage, wherein the insert housing has sidewalls along the insert passage between the first and second ends of the vertical passage, wherein the baffles are perpendicular to the sidewalls and have a uniform thickness, wherein said insert housing has a first inner diameter and a second inner diameter at the nozzle end, the second inside diameter being less than the first inner diameter.
A discharge assembly for mixing at least one stored liquid comprising:
- a nozzle having a vertical passage and a horizontal passage integrally formed within a nozzle housing, the horizontal passage having an inlet end for receiving liquid and an outlet end, the vertical passage having a first end fluidly coupled to the outlet end of the horizontal passage and a second end at a liquid dispensing location;
- and
- a removable insert having a housing defining an insert passage and having a plurality of inwardly-directed baffles, the insert housing further having a nozzle end near the outlet end of the vertical passage, wherein the insert housing has sidewalls along the insert passage between the first and second ends of the vertical passage, wherein the baffles are perpendicular to the sidewalls and have a uniform thickness, wherein the insert includes a plurality of ribs on an outer surface of the insert housing to permit the vertical passage to firmly maintain the insert and to enable slidable removal of the insert from the vertical passage through the outlet end of the vertical passage when a force is applied to the insert.
A discharge assembly for mixing at least one stored liquid comprising:
- a nozzle having a vertical passage and a horizontal passage integrally formed within a nozzle housing, the horizontal passage having an inlet end for receiving liquid and an outlet end, the vertical passage having a first end fluidly coupled to the outlet end of the horizontal passage and a second end at a liquid dispensing location;
- and
- a removable insert having a housing defining an insert passage and having a plurality of inwardly-directed baffles, the insert housing further having a nozzle end near the outlet end of the vertical passage, wherein the insert housing has sidewalls along the insert passage between the first and second ends of the vertical passage, wherein the baffles are perpendicular to the sidewalls and have a uniform thickness, and wherein the second end of the vertical passage has an inner diameter that is sufficient to permit the insertion and removal of the insert through the second end of the vertical passage.
A discharge assembly for mixing at least one stored liquid comprising:
- a removable insert having a housing defining an insert passage and having a plurality of inwardly-directed baffles, the insert housing having an inlet end and a nozzle end;
- and
- a nozzle having sidewalls defining a nozzle passage, and having an inlet end for receiving liquid and an outlet end having an inner diameter that is sufficient to permit the insertion and removal of the insert through the outlet end of the nozzle.
