Attorney, Agent, or Firm-Richards, Harris & Medlock  ABSTRACT A high volume stadium type filler for delivering sub stantially uniform chilled carbonated beverages at high volume wherein an ice chest is provided with a carbonator tank therein, a drain in the bottom near one end thereof leading through a pump and a baffled chamber extending the height of and in the other end thereof with water cooling coils in the chamber leading from a pressurized source to the carbonator with means for delivering water from the bottom of said carbonator to a dispensing valve simultaneously with syrup, both under CO gas pressure. 9 Claims, 2 Drawing Figures FATENTED m 7 i974 SHEET 2 OF 2 STADIUM FILLER SUMMARY OF THE INVENTION This invention relates to a system for delivering chilled carbonated beverages in multiple streams and- /or at high volume to permit dispensing in individual containers to large crowds. In a more specific aspect, the invention relates to a stadium type of cup filler with a cool reservoir (ice orelectric) adapted to maintain a carbonator and the effluent therefrom chilled even .though the flow of water thereto is ata high temperature and the throughput is at a high volume.
Delivering of high volumes of carbonated beverages in short periods of time as at sporting events and the like can readily be accommodated by the installation of large capacity refrigeration systems. However, the economics involved in such operation have forced concessionaires to less sophisticated systems and primarily to those systems in which the latent heat involved in an ice bank is employed.
In prior art systems, large cooling coils have been installed in the bottom of an ice chest and coveredv with an ice bank. Makeup water to. a carbonator drawn through the cooling coils is thus to be chilled. Bridging of ice in the ice bank at the bottom portion thereof has been found to be such that the lake of water which forms as the makeup water courses through the coil rapidly increases in temperature, resulting in the delivery of an inferior product. The present invention is directed to a system which overcomes the foregoing problems and, with minimum equipment, assures high volume delivery of a substantially uniform chilled carbonated beverage.
More particularly, in accordance with a preferred embodiment of the present invention there is provided a combination of an ice chest that has a baffled chamber in one end in which cooling coils are located. A carbonator located within the chest is connected by water BRIEF DESCRIPTION OF THE DRAWINGS For a more complete understanding of the present invention and for further objects and advantages thereof, reference may now be had to the following description taken in conjunction with the accompanying drawings in which:
FIG. 1 is a view illustrating a high volume dispensing system which embodies the present invention; and
FIG. 2 is a drawing illustrating the carbonator filler arrangement of FIG. 1.
DESCRIPTION OF A PREFERRED EMBODIMENT FIG. 1 illustrates a high volume system for dispensing post mixed carbonated beverages employing the present invention. A pair ofrails and 11 extend from a cup dropping station 12 to an output station 13. A
mesh wire rack 14 is adapted to be-placed on the rails 10 and 11 and passed beneath a cup dropper 15 wherein a plurality of cups simultaneously are deposited in the rack 14 in a 4 X 6 array. Twenty-four cups are simultaneously placed there.
Rack 14 is then moved forward to a location beneath a cup icer unit 16 wherein each of the cups is filled with crushed ice. The rack is then moved to the position shown in FIG. 1 wherein each transverse row of cups, four cups at a time, pass beneath four spouts depending from an overhead unit 17 which is positioned above and is a part of a filler unit 18.
The cups are then filled and then moved to a cup capping unit 19 wherein the twenty-four cups in a rack 20 simultaneously are capped. Thereafter, rack 20 is moved to the output station 13 as rack 14 is moved under the capper 19. I
A plurality of syrup tanks 21 are provided adjacent to the carbonator 18 to store syrup for chilled carbonated water provided in the tiller unit 18. A source of water and a source of carbon dioxide (not shown) are provided so that the conventional carbonated beverages are supplied to the cups in the racks.
The problem to which the present invention is directed is to provide a filler unit having a carbonator which has such high capacity and yet remains relatively simple in its construction, as to permit a high throughput. In satisfying the demand at sporting events, such as football games, baseball games, and the like, a high demand over a short period of time is imposed upon as comprising an open topped ice chest containing therein a carbonator 30. CO gas from a tank 31 is sup- Chilled carbonated water travels by way of a tube 36- which extends to the bottom of the tank 30, and line 37 to a manifold 38.
An output line 39 from the manifold 38 leads to a dispensing valve 40, In the system shown in FIG. 1, four lines such as line 39 lead to four valves such as valve 40 all actuated simultaneously by a single lever 41, FIG. l.
Syrup from syru'p tanks 42 is forced through a line 43, a cooling coil 44 and a line 45 to the valve 40 wherein the syrup is mixed with the carbonated water in the desired proportions. Drive energy for the syrup is supplied by way of a C0 purge line 46 leading from the top of the carbonator tank 30 to a manifold 47 which is connected to the syrup tanks 42.
Water is supplied to the system by way of a line 50 which passes through a pressure regulator 51 to pump 52. Pump 52 forces the makeup water through line 53 and cooling coil 54 and then by way of line 55 to a spray float controlled valve 56 in the lid of the carbonator 30. Regulator 51 normally is set at about 20 p.s.i. and regulator 31a on CO tank 31 is set at about 55 p.s.i.
The problem involved in maintaining the capability of deliveringhigh volumes of substantially uniformly chilled carbonated beverages ismet by the presentinvention by employing a large volume chest for filler 18 in which a large ice bank 60 may be provided. Initially in a given operation ice bank 60 may completely cover the carbonator and extend nearly to the top of the filler 18.
As the ice melts, a pool 61 of water accumulates in the bottom of the filler 18; In accordance with the present invention, an intake pipe 62 leads from a filter 63 to a pump 64. Pump 64 picks up water from-the bottom of the tank in the lower right-hand corner thereof. Filter 63 prevents the circulation of ice particles and limits the flow through the pipe 62 to water. The inlet of pump 64 is connected to pipe 62. The outlet of pump 64 is connected to the bottom of a chamber 65 formed in the left end of filler 18 by a baffle 66. A coil 54 through 'which the water passes is' confined within the chamber 65. The water at about 32 picked up at the bottom of the filler 18 passes from the bottom of the chamber 65 to the top passing over'the water cooling coil 54 and the syrup cooling coil 44. The water then spills out of the top of the chamber 65. Note that the baffle 65 is positioned in the end of the chest 18 opposite the filter 63. By this means, the cold storage represented by theice bank may be fully utilized for maintaining 32 water constantly flowing into the cooling chamber 65. This system avoids bridging of the ice in filler 18 by maintaining the flow of water the length of the chest 18 after it spills over the baffle 66. Thus, by controlling the movement of the cooling water through the filler 18, a more efficient operation of the carbonator is assured. I
It has been found that the arrangement herein provided, limiting the flow as shown in FIG. 2, permits the delivery of chilled beverages from the valve 40 on the average of to l2 colder than normally is delivered through contemporary systems which do not include the cooling provisions as above described.
It will be noted that the pump 52 for makeup water is provided with. a bypass channel. The line 71 is provided from line 35 to the input to the pump 52 so that when the valve 56 is closed, a small stream of water will continuously be circulated through the loop which includes line 71 to prevent pump 52 from overheating.
coil is'located within the chamber over which the chilled water from the circulating pump flows. A carbonator tank is connected to the outlet of the cooling coil for receiving and carbonatingchilled water from the cooling coil. A mixing-dispensing valve connected 'to the carbonator controls the flow of chilled water from the carbonator. A syrup tank connection leads to the valve for delivering syrup thereto for mixture with water from the carbonator. A pressurized source of carbon dioxide gas is flow connected to deliver gas to the bottom of the carbonator and thence from the top of the carbonator to the top of the syrup tank to pro- The pump bypass 70 eliminates the need for any pres- I sure switches in .the system and permits the pump 52 to be operated continuously even though water is not being withdrawn from the system."
By way of example, in operation of one embodiment of the system, the regulator 51 was set at 20 p.s.i. pressure. The CO gas source was regulated at about 55 p.s.i. The valve 56 in carbonator 30 was set to close and hold off flow from pump 52 at about 170 p.s.i. The pump bypass in loop 70 was set to open at about 150 p.s.i. By this means, it is assured that the water pressure from pump 52 would not override float 34 as it closes valve 56 thereby avoiding flooding the carbonator 30. The capillary bypass line 71 leading from the outlet point of the coil 54 assures a continued flow of chilled water into the pump sufficientto prevent the pump from heating.
Thus, in accordance with the invention, an ice chest is provided having a drain pipe with a pickup zone therefor at the bottom of the chest and in one end thereof with structure forming a chamber in the oppovide a drive force .on both the water in the carbonator tank and syrup in the syrup tank while carbonating water in the carbonator tank. 7
In preferred form, the cooling coils 54 are arranged in downwardly arrayed horizontally extending sections or loops, all contained within a' set of vertical baffles 54a. The baffles are parallel vertical plates to require laminar flow of water over coils 54 greatly to increase the efficiency of the system. Ascending chilled water from plenum chamber 65a below the baffles 54a is uniformly distributed to all parts of the cooling coil 54 as it flows upward through a tortuous restrictive path' over the coils.
Having described the invention'in connection with the embodiment illustrated in FIG. 2, it is to be understood that further modifications thereof may now appear to thoseskilled in the art and it is intended to cover such modifications as fall within the scope of the appended claims.
