  • the beverage dispensing system has a water inlet 1 l for being connected to a supply of pressurized potable water.
  • the inlet 11 leads to a strainer 12 which is connected to a pressure regulating valve 13 from which a water line 14 extends in the form of a helical coil. Downstream of the water line coil 14, the line is connected to a first main or dispensing valve 15, a further main or dispensing valve 16, a flushing valve 17 and a further flushing valve 18.
  • the dispensing valves 15, 16 communicate through a pair of lines 19, 20 with a water inlet 21, 22 forming part of a mixing and dispensing spout 23, 24. Water from the dispensing valves 15, 16 is also carried by a pair of bypass lines 25, 26, each of which has a check valve 27, 28 and a manually adjustable throttling valve 29, 30. Each of the dispensing spouts 23, 24 has a flow restrictor 86 by which a back pressure is created.
  • the beverage dispensing system 10 further includes a pair of storage tanks 31, 32 which may be constructed as a partitioned unit with a single cover 33. The cover enables air to enter the tanks 31, 32 as liquid flavored beverage ingredient is withdrawn therefrom.

  • Each of the ingredient lines 34, 35 further includes a control member 40, 41, such control members here comprising a pump, such as of the peristaltic type driven by an electric motor 42, 43.
  • the flushing valves 17, 18 are connected by a pair of flushing lines 44, 45 with the beverage ingredient lines 34, 35 close to the point where the bypass lines 25, 26 join the ingredient lines 34, 35, such connection being upstream of the control member 40, 41.
  • Each of the dispensing spouts 23, 24 has an air inlet 46, 47 which is connected to an air throttling valve 48, 49 which enables a selected amount of air to be drawn into the mixing and dispensing spouts 23, 24, such as air being at atmospheric pressure and obtained from any suitable ambient location.
  • the down-tumed portion of the spouts 23, 24 should really be illustrated as extending downwardly, perpendicular to the plane of the drawing as shown in FIG. 6 in horizontal cross sectional view).
  • pressurized water flows through the line 19 into the water inlet 21 and through the flow restrictor 86.
  • the backpressure in line 19 upstream from the flow restrictor causes water to flow through the bypass line 25, the check valve 27 and the adjustable throttling valve 29 which are connected to the suction side of the pump 40 so that a mixture of beverage ingredient from the check valve 38 and water from the throttling valve 29 are drawn into and metered by the control member or pump 40, the outlet of which is connected to the beverage ingredient inlet 36.
  • the stream of water and the stream of partially diluted beverage concentrate engage against each other to further dilute the concentrate to the proper degree, a preselected amount of air being drawn in and also mixed therewith through the air inlet 86.
  • the operation of the dispensing valve 16 and control 41 in bringing water to the dispensing spout 24 and in bringing beverage ingredient from the source 32 to the spout 24 is identical to that explained.
  • the dispensing valve and the control member 40 are operated until the source 31 is empty whereupon the same can be readily wiped out.
  • the flushing valve 17 is also energized, clear water flows through the flushing line 44, bypassing the check valve 27 and the throttling valve 29, at a flow rate at least equal to the flow capacity of the control member 40.
  • the check valve 27 and the throttling valve 29 do not need to be cleaned because in their ordinary operation, they handle the same water.
  • the flushing water is prevented from entering the source 31 by the check valve 38 and is also connected to the upstream sideof the control member or pump 40, thereby flushing the beverage ingredient line 34 including the control member 40 and the inlet 36 of the dispensing spout 23.
  • the other spout 24 receives flushing water by energization of the flushing valve 18.
  • a hermetically sealed motorcompressor 50 has an output line 51 leading to a condenser coil 52 which is air-cooled by a ventilating fan 53.
  • the line 51 then leads to a strainer-dryer 54 and thence through several feet of a first capillary tubing 55 which typically has an inside diameter of 0.049 inch.
  • the line 55 divides at a point 56 and a second capillary tubing 57 of smaller inside diameter leads to an evaporator coil 58 which is disposed in heat-exchange relationship with the sources 31, 32.
  • the discharge end of the evaporator coil 58 passes through a downwardly directed section line 59 (for draining the evaporator coil 58) to an accumulator 60 which is connected to a suction line 61 leading to the motor-compressor 50.
  • the other branch 62 leads through a solenoid valve 63 to a line 64 which is arranged in the form of a vertical helical coil, the discharge end, as shown in dashed lines, being also connected to the lower end of the accumulator 60 via a vertical loop or trap 89 which prevents backflow of refrigerant into the helical coil 64 from the evaporator 58.
  • the upper and lower loops of the coil 14 are bonded as at 91 to a pair of mounting brackets 92, 93, for a purpose explained below.
  • the helical coil portion of the refrigerant line 64 is disposed within the helical water coil 14 as best seen in FIG. 5. Although the turns of the helical coil of the refrigeration line 64 are shown as being concentric with the individual turns of the water lines helical coil 14, the actual location is at random since the coils are formed after the assembly is made. Refrigerant enters the upper end of the helical coil and exits through the lower end, while the warmer water enters the lower end of the coil 14 and flows in surrounding relation to the refrigerant coil and exits at the upper end.
  • the accumulator is disposed within the helical coil 14, as shown.
  • a first thermostatic control is provided which is responsive to the temperature of the water line helix 14, and a second temperature control 66, shown in FIG. 1 is disposed so as to be responsive to the temperature of the beverage ingredient source.
  • the first thermostatic control 65 has a sensing element 67 and an electric switch 68, and is of the limited vapor filled type so that it is responsive to the coldest part of the sensing element.
  • the sensing segment 67 is constructed with a zig-zag portion at the lower end of the helical coil 14 and a shorter zig-zag portion near the upper end thereof.
  • the coldest water which is at the upper end of the helical coil 14 is sensed to open the switch 68 and the warmest water, such as fresh incoming water is sensed at the lower end of the water coil 14 to call for refrigeration.
  • the sensing element 67 extends from the top of the water line 14 and is covered with insulation 90 which shields the elements 67 from the cold air around the water coil 14 which air, during operation of the refrigeration system, will be colder than the water coil 14.
  • the switch 68 is in circuit with the refrigeration solenoid valve 63 which is normally closed so that unless the thermostatic control 65 is calling for refrigeration, the solenoid valve 63 will be closed. When refrigeration is called for, the compressor 50, the fan 53 and the solenoid valve 63 are simultaneously energized.
  • the various portions or stretches of the sensing element 67 lies intermediate adjacent turns of the water helix l4 and in direct engagement with both adjacent turns for ensuring good heat transfer and for obtaining accurate sensing of water temperature.
  • an arcuate clamp 69 shown only in FIG. 3 which acts through slightly yieldable insulation 70 to maintain good contact between the sensing element 67 and the water line helix 14, for example, as'seen between the points 67a and 67b.
  • the evaporator line 58 is in parallel to the lines 62, 64 and is controlled only by the capillary tubing 55 and 57 from a refrigerant gas standpoint, while the second thermostatic control 66 is arranged to turn the com-- pressor 50 and fan 53 on and off.
  • the evaporator coil 58 will receive refrigerant gas.
  • the thermostatic control 65 which typically operates in the temperature range between 35 and 38 F keeps the temperature of the coldest water above freezing.
  • a liquid level senser 71 has two sensing elements 72, 73, respectively insulatingly disposed for extending into concentrate in the concentrate sources 31, 32. When the liquid level falls below either of them, a circuit is closed to a warning lamp for indicating that the supply of beverage ingredient is low.
  • the thermostatic control 66 has a switch 74.
  • a line 75 brings power to the switches 74, 68.
  • the water thermostat switch 68 is connected to the normally closed stationary contact 76 of 5 a relay 77 and is also connected to bring power to the solenoid of the refrigeration valve 63.
  • the movable or armature contact 78 of the relay 77 is connected to bring power to the motor of the compressor 50 and to the motor of the fan 53.
  • the thermostatic control 65 energizes the parallelconnected refrigeration valve 63, compressor 50 and fan 53.
  • the switch 74 which is a part of the concentrate thermostat 66 brings power to the coil of the relay 77 and also brings power to the normally open stationary contact 79. Thus when the switch 74 is closed alone, power is delivered to the compressor 50 and fan 53.
  • the circuitry for the refrigeration system is independent of other switches so that if the dispenser is plugged into a power source, it cannot be shut off accidentally.
  • the keyoperated switch 80 is in series with a master switch 81 which controls power for the vending of both flavors.
  • the master switch 81 is connected to a pair of dispensing switches 82, 83 which are respectively connected to bring power to the dispensing valve 15 and motor 42, and the dispensing valve 16 and the motor 43 respec tively.
  • the solenoids of the flushing valves 17, 18 are also connected to receive power from the dispensing switches 82, 83 but in the return line of each of the solenoid valves 17, 18, there is a flushing switch 84, 85 so that flushing will take place only when the same is closed.
  • the actuators may be mechanically ganged. With this arrangement, either or both of the systems within the dispenser may be flushed.
  • the switches 84, 85 could be in series with the other terminal of the flushing valve solenoids.
  • the adjustability of the throttling means 29, 30 has several advantages.
  • One advantage is that the apparatus can be used with beverages that have reconstitution ratios between 1 to 3 and 1 to 5, whereby such ratio is selected.
  • a second advantage is that beverage ingredients reconstituted at a selected ratio do not all have the same viscosity at a given operating temperature.
  • the control members 40, 41 when comprising peristaltic pumps, have a flexible tube section which decreases in size under suction as a function of viscosity and such decrease is compensatable by the aforesaid adjustability.
  • the check valves 38 and 39 in the ingredient lines 34, 35 are preferably spaced upstream by a portion 87, 88 of each such line from the point at which the flush lines 44, 45 are connected.
  • the beverage ingredient is a citrus concentrate
  • some pulp will occasionally be trapped against the seat of the check valve 38, 39, thereby slightly holding the check valve 38, 39 open. This condition is of no consequence during ordinary sequential dispensing.
