Definitions

  • This invention relates to beverage or beverage component cooling and pumping systems and has particular, but not exclusive, reference to such pumping systems intended to pump carbonated water around a soda circuit.
  • Ice bank cooling systems are well known. Such systems incorporate a reservoir containing water and two sets of coils. The first coil comprises the expansion portion of a refrigeration circuit and the second coil is a heat exchanger for cooling beverage or a beverage component such as a concentrate or diluent.
  • the operation of the refrigeration system builds up a layer of ice on the refrigerant coils which acts as a store of cold and enables a smaller refrigeration unit running for longer time periods to cool beverages where the demand occurs in peaks throughout the day.
  • a motor may be connected directly via a shaft to the paddle or agitator or may be connected indirectly utilising a magnetic coupling system as is for example described in UK patent application GB-A-2 167 845.
  • a coil or other form of heat exchanger for the beverage or beverage component is immersed in the coolant and cools the beverage or beverage component which passes through the coil.
  • the beverage or beverage component is passed through the coil under pressure from an external source.
  • a pump is used to pump a beverage or beverage component through the coil.
  • a loop for a soda circuit in which carbonated water is continuously pumped around a loop and is tapped off at locations around the loop for supply to a beverage mixing apparatus.
  • the carbonated water is pumped by means of a conventional electrical pump which therefore has to handle the cold soda water.
  • Such pumps normally operate 24 hours a day and continuously circulate chilled water through the soda circuit.
  • 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 shaft connected to the agitator, a pump for pumping the beverage or 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 magnetic coupling is located upon the shaft between the agitator and the pump.
  • the pump may be immersed in the coolant liquid or may be located exteriorly of the reservoir which is formed at least in part of a non-ferromagnetic material permitting coupling magnetically through the wall.
  • the pump when mounted in an exterior position may be thermally insulated from the external atmosphere.
  • the circuit may include a heat exchanger immersed at least in part in the coolant liquid.
  • the pump may have two feeds and a single outlet, one feed for a return from the circuit and the other feed for a circuit top up from a carbonator.
  • the motor may be an electric motor and may be a two-pole electric motor.
  • the liquid coolant may be water and there may be provided means to freeze part of the water in the reservoir.
  • the system may incorporate a carbonator for carbonating water.
  • the present invention further provides a beverage or beverage component cooling system including a reservoir of coolant liquid, an electric motor located above the reservoir, a shaft dependant from the motor and having agitator means therein within the reservoir, a magnetic coupling at the end of the shaft interengaging the shaft and a pump for pumping the beverage or beverage component through a circuit.
  • this shows a circuit 1 in the form of a loop which extends from and to a pump 2 and incorporates a 'T' lead off 3.
  • the 'T' lead off heads towards a valve 4 which controls the flow of said water to an exit point or nozzle 5.
  • the valve 4 may be part of a system for mixing carbonated water with a drink concentrate or may be a simple control valve.
  • the pump 2 has a pair of inlets 6, 7.
  • the inlet 6 is for the return from the circuit 1 and the inlet 7 is for replenishment of soda water from a carbonator 8.
  • the pump 2 runs continuously and would normally circulate water around the circuit 1. However, in the event of carbonated water being drawn through valve 4 top up for the circuit is provided by carbonator 8.
  • the carbonator 8 is supplied by a carbon dioxide line 9 and a water line 10 incorporating valves 11 and 12.
  • the remote carbonator 8 is of conventional form.
  • the circuit 1 incorporates a heat exchanger to maintain the carbonated water at a low temperature and the circuit itself is normally insulated.
  • the pump 2 and its cooling system is shown in more detail in Figure 2.
  • the pump 2 has an output through line 13 into a heat exchanger 14 which forms part of the circuit 1.
  • Feed line 15 leads to port 7 and feed line 16 leads to port 6.
  • the pump 2 is immersed in water 17 contained within an insulated reservoir 18.
  • Also within the reservoir is a refrigeration coil 19 shown surrounded by an ice bank 20 in a conventional manner.
  • the water within the reservoir is agitated by agitator paddle 21 fixed to shaft 22 and driven by electric motor 23.
  • a magnetic coupling 24 interconnects the shaft 22 and the pump 2.
  • the agitator pump and motor system are shown in more detail in Figure 3.
  • the electric motor 23 which forms the power means for the system comprises a two-pole motor having a cooling fan 25 and being supported on a frame 26 to which is mounted a pump head 27 being part of the pump 2.
  • the agitator paddle 21 is mounted on the shaft 22 and the end of the shaft terminates in a magnetic coupling 24 which couples to a corresponding portion of a magnetic coupling in the pump head.
  • the outlet line 13, the pump itself 2 and the inlet lines, one of which 15 is shown in Figure 3, are all immersed in the coolant water. Because the magnetic coupling avoids the need for seals, the pump can be completely sealed from the water 17 in the reservoir.
  • the pump 2 has a single inlet and the top up line from the carbonator 8 is fed into the loop 1. This means that there is only a single seal for the inlet to the pump and a single seal for the outlet.
  • the feed line or lines to the pump may be led over the top of the wall 18 of the reservoir so as to avoid the need for seals in the wall of the reservoir.
  • the pump 2 could be located outside the reservoir 18 which could have a pocket for the pump provided that the wall of the reservoir was not ferromagnetic for the region where the magnetic coupling was to make the connection.
  • a system would require insulation to prevent condensation from the pump damaging the container or its surroundings.
