Definitions

  • This invention relates to a beverage or beverage component cooling and pumping system. Such systems are frequently used as part of an ice bank cooling system for the chilling of beverages such as carbonated water or beer. Another name for carbonated water is soda.
  • ice bank cooling systems there is a reservoir containing two sets of coils.
  • the first coil comprises the expansion portion of a refrigeration circuit and acts to cool the water in the reservoir to form an ice bank.
  • the second coil which passes through the water/ice bath or reservoir, is a heat exchanger for cooling a beverage or a beverage component such as a concentrate diluent.
  • a pump may be located within the reservoir to pump the chilled beverage towards its dispense point.
  • Such pump is typically driven by a motor located above the reservoir, and the same motor may be used to drive an agitator in the form of a paddle to prevent temperature stratification of the water within the reservoir.
  • a motor located above the reservoir, and the same motor may be used to drive an agitator in the form of a paddle to prevent temperature stratification of the water within the reservoir.
  • GB-A-2 167 845 is described a different system in which the motor is located within the reservoir and has a magnetic coupling thermally insulated from a shaft carrying an agitator.
  • the coupling provides the means to drive the agitator and a pump both of which drive coolant liquid rather than the beverage to be cooled.
  • a beverage or beverage component cooling and pumping system including a reservoir of coolant liquid, an agitator for agitating liquid in the reservoir, power means located above the reservoir and arranged to drive a first shaft which conveys rotation to the agitator, a pump for pumping the beverage component through a circuit, the pump being driven by the same power means as the agitator and being magnetically coupled to the power means by a magnetic coupling, characterised in that the pump and the magnetic coupling are located upon the shaft between the motor and the agitator.
  • a further magnetic coupling may be provided between the pump and a second shaft co-axial with the first shaft, and the agitator may be located upon the second shaft.
  • an electric motor (or power means) 10 drives a shaft 11 which extends downwardly from motor 10 into a reservoir of water.
  • Shaft 11 passes through a detachable cover plate 17.
  • Cover plate 17 is located in a cover for the reservoir and is designed to contain evaporation from the surface of the water.
  • a paddle-shaped agitator 19 Attached to the end of shaft 11 is a paddle-shaped agitator 19 which can agitate the water in the reservoir.
  • arms 13 extend radially outwardly at an angle from shaft 11. Arms 13 encompass the driving part 20 of a magnetic coupling 20 at their ends remote from shaft 11.
  • a set of stays 18 depend from the perimeter of cover plate 17 in the same direction as shaft 11 to support a pump housing 14 surrounding shaft 11 between the arms 13 and the agitator 19.
  • the pump housing 14 has within it a pump impeller 15 which drives beverage entering the pump housing 14 towards a remote dispense point (not shown) for the beverage.
  • the beverage is soda.
  • the pump impeller 15 is driven, not directly from shaft 11, but through the magnetic coupling.
  • the driving part of magnetic coupling 20 co-operates magnetically with a driven magnet 16 which is radially inboard of the driving part 20, but inside pump housing 14 and connected to impeller 15. Rotation of shaft 11 thus causes direct rotation of agitator 19, and indirectly, through the magnetic coupling, the rotation of pump impeller 15.
  • the positioning of the impeller deeper in the reservoir provides for improved agitation of the water reservoir in deep baths.
  • a motor 110 drives a shaft 111 which extends vertically downwards into a water reservoir.
  • a pump housing 114 is located and supported by stays 118 which surround shaft 111.
  • Pump housing 114 contains an impeller 115 which has an annular or hollow vertical shaft 121 which can rotate about a spindle 126 which is attached to pump housing 114.
  • Spindle 126 and cylindrical shaft 121 are co-axial with but spaced axially from drive shaft 111.
  • Arms 113 similar to arms 13 of Figure 1, extend from adjacent the end of drive shaft 111 remote from motor 110. Arms 113 retain the driving part 120 of a magnetic coupling which extends around the upper part of pump housing 114. Co-operating with driving part 120 is a driven magnet 116 located within pump housing 114 and attached to the upper end of hollow shaft 121. Hollow shaft 121 is thus caused to rotate by magnetic coupling between the driving part 120 and the driving part 116 of the magnetic coupling when shaft 111 is rotated by motor 110.
  • the lower portion of the hollow shaft 121 which carries pump impeller 115 also carries a magnetic driving component 122, located beneath impeller 115.
  • Component 122 is cylindrical in shape and co-axial with the previously mentioned magnetic driving means and with shaft 111.
  • An agitator 119 attached to a lower shaft 124 extends beneath pump housing 114 and is coupled magnetically to hollow shaft 121 through the magnetic drive component 122 and magnetically driven member 123.
  • the bottom end of lower shaft 124 is located and supported so that it extends co-axially with drive shaft 111 by means of extensions 125 of stays 118 and a lower location member 128 attached to extensions 125.
