Cross-Reference To Related Applications

[0001] This application claims priority to U.S. Provisional Patent Application Serial No. 63/569,714, filed March 25, 2024, the disclosure of which is incorporated herein by reference in its entirety.

Background

[0002] In the food preparation industry, it is important to mix ingredients to achieve an interim or final product. Prior mixing devices include passive, as well as active, mixing devices. Examples of passive mixing devices are devices which, by way of example, but not limitation, introduce beverage concentrate flowing into a stream of diluent, such as water. In some situations, this passive mixing may be acceptable depending on the type and nature of the concentrate as well as the diluent material, such as water.

[0003] In situations where passive mixing may be preferable for a variety of reasons, it is also important to make sure that the desired mixing results are achieved. Recently, in the area of beverage concentrates, the trend by the concentrate manufacturers is to increase the viscosity of the concentrate material. For example, while concentrate to diluent ratios of 4:1 are common, beverage concentrate manufacturers are increasing ratios to 5:1 and beyond. This increase in concentrate viscosity requires new systems, methods and apparatus for mixing the concentrate with water.

[0004] Concentrate materials may include increased levels of crystalline compounds, such as potassium citrate, which collect in the mixing cavity of a passive mixing device. The presence of these compounds within tight-tolerance passive mixing systems lowers mixing efficiency, creating stratification of Brix measurements throughout a final mixed product. Further, these compounds, when collected for sufficient time in the mixing cavity, may result in clogging of the passive mixing device. As such, there is room in the art for passive mixing devices which maintain a consistent Brix measurement of a final mixed product, such as a beverage, while providing additional area for mixing within a mixing cavity. It is further advantageous if these benefits can be achieved through a kit to retrofit an existing passive mixing device.

[0005] This background information is provided merely for context. No admission is intended, nor should such admission be inferred or construed, that any of the preceding information constitutes prior art against the present disclosure. Other aims, objects, advantages and features of the invention will become more apparent upon reading of the following non- restrictive description of specific embodiments thereof, given by way of example only with reference to the accompanying drawings.

Detailed Description

[0028] An exemplary component mixing system 10 in accordance with an embodiment of the present disclosure is illustratively shown in Fig. 1. The mixing system 10 is shown in diagrammatic form to present the general principles and structures associated with exemplary systems, methods, and apparatuses of the present disclosure. The mixing system 10 includes a mixing device 12 coupled to a first ingredient source 24, such as a container of juice concentrate, and a second ingredient source 34, such as a water line or other diluent supply, and mixing control components such as a controller 50 configured to control operation of the mixing device 12 and/or the flow of first and second ingredients 20, 30 into the mixing device 12.

[0029] In the illustrative embodiment, the mixing device 12 includes a body 14 defining an internal cavity 11 and a first inlet 15, and a second inlet 16 coupled to the body 14 and extending into the cavity 11. The first inlet 15 is in fluid communication with the cavity 11, and the body 14 also defines an outlet 17 spaced apart from the first inlet 15 and in fluid communication with the cavity 11. The second inlet 16 extends from a proximal end adjacent the outlet 17 to a distal end adjacent the first inlet 15 to define a flow path 19 through the cavity 11 from the first inlet 15 to the outlet 17. The first inlet 15 allows a first ingredient 20, such as a juice concentrate, to flow into the cavity 11 for mixing with a second ingredient 30, such as water, flowing through the second inlet 16 to form a mixture 40, such as a beverage, for dispensing from the mixing device 12 through the outlet 17.

[0030] As used throughout, the term "concentrate" is intended to be broadly interpreted as an ingredient, which in one embodiment is a concentrate for beverages and other food substances including, by way of example, but not intended to be limited to, juice, tea, coffee, sugar-based beverages, dairy-based beverages, soda-fountain beverages, sports drinks, combinations of any beverages or beverage concentrates, as well as other food substances which might also benefit from the devices, systems, and methods for mixing of the present disclosure. Similarly, the term "diluent" or "water" is intended to be broadly interpreted as an ingredient for beverages and other food substances as noted above. While the present disclosure uses the term "water" and "diluent" generally interchangeably, a variety of diluent materials may be used to produce a variety of beverage products. For example, diluent may be another ingredient such as anotherflavoror base ingredient otherthan water. Further, the diluent could be anotherform of ingredient such as a liquid, gel, gas, ice crystals, or any other substance that is mixed with at least one other substance to produce the desired resultant mixed product.

[0031] Returning to Fig. 1, the exemplary second inlet 16 defines an internal passageway 61 for flow of the second ingredient 30 through the second inlet 16 and out of a plurality of openings 63 in the second inlet 16 into the cavity 11 for mixing with the first ingredient 20. The plurality of openings 63 are arranged at a location along the second inlet 16 between the first inlet 15 and the outlet 17. In the illustrative embodiment, the plurality of openings 63 are configured to direct the second ingredient 30 in a substantially radial direction. In some embodiments, the openings 63 are each configured (e.g., by shape and/or size) to provide narrowly-directed, localized streams of the second ingredient 30 into the cavity 11 at a relatively high speed compared to a stream of the first ingredient 20 flowing into the cavity 11. In some embodiments, the openings 63 are nozzles configured to provide a defined flow pattern such as in the form of a fan, ring, point, or any other shape for relatively high speed delivery of the second ingredient 30 (e.g., as a jet stream) into the cavity 11 compared to a stream of the first ingredient 20 flowing into the cavity 11.

[0032] The flow of the second ingredient 30 exiting the second inlet 16 through the openings 63 forces the first ingredient 20 against the body 14 (e.g., an inner surface of the cavity 11) to maximize mixing ofthe first and second ingredients 20, 30 and to provide shearing and/or cutting forces to maximize breakdown and/or dissolution of clumped particles and other compounds within the first ingredient 20 in the mixture 40 with the second ingredient 30. For example, in some embodiments, the first ingredient 20 is a juice concentrate containing a relatively high percentage of crystalline compounds, such as potassium citrate, and/or fibrous material (e.g., pulp), and the flow of the second ingredient 30, such as water, exiting the openings 63 impinges on the particulates in the first ingredient 20 to break down larger particles or clumps of material into smaller portions as suggested in Fig. 1. In some embodiments, an outer surface of the exemplary second inlet 16 is spaced apart from an inner surface of the cavity 11 to allow larger particulates to pass from the first inlet 15 to the outlet 17 to minimize clogging of the mixing device 12.

[0033] In some embodiments, an upstream end of the cavity 11 (e.g., adjacent to the first inlet 15) is spaced apart from a distal end of the second inlet 16 (e.g., adjacent to the openings 63) defining a chamber where some mixing of the first and second ingredients 20, 30 can occur. The combined mixture 40 flows along the flow path 19 from the chamber at the upstream end of the cavity 11 toward the outlet 17. The ingredients 20, 30 within the mixture 40 will continue to mix as they flow toward the outlet 17 into a generally integrated, homogeneous product, such as a beverage. The consistency of the beverage is a result of the physical agitation, impact, and/or collision of the ingredients 20, 30 in the cavity 11 and flow along the flow path 19. The mixture 40, once moving along the flow path 19, is generally already homogeneous and fully dissolved, mixed or otherwise is a chemical combination of the at least two ingredients such as water and concentrate. This thorough mixing prevents separation, stratification, or other settling or separation of the concentrate and water once it is dispensed from the outlet 17. It should be noted that the various dimensions, shapes, proportions and relationships may be varied to some degree to achieve the same or similar results as generally described and disclosed herein.

[0034] The flow of ingredients 20, 30 into the cavity 11 can be accurately controlled through various control components as shown in Fig. 1. The control components are to be broadly interpreted but may include, by way of example and not limitation, the controller 50, one or more of a pump device 22, a controllable inlet valve 26, and/or a flow regulator 28 coupled to the first ingredient source 24 and to the first inlet 15 by an inlet passage 21, and one or more of a pump device 32, a controllable inlet valve 36, and/or a flow regulator 38 coupled to the second ingredient source 34 and to the second inlet 16 by an inlet passage 31. The pump device 22, controllable inlet valve 26, and/or a flow regulator 28 can be arranged in any order between the first ingredient source 24 and first inlet 15, and the inlet passage 21 includes one or more fittings, connectors, hoses, or pipes, for example, to direct a flow of the first ingredient 20 from the first ingredient source 24 and through the various control components to the first inlet 15. The pump device 32, controllable inlet valve 36, and/or a flow regulator 38 can be arranged in any order between the second ingredient source 34 and second inlet 16, and the inlet passage 31 includes one or more fittings, connectors, hoses, or pipes, for example, to direct a flow of the second ingredient 30 from the second ingredient source 34 and through the various control components to the second inlet 16. The exemplary pump devices 22, 32 are configured to pressurize and/or accelerate the flows of ingredients 20, 30 directed to the first and second inlets 15, 16, respectively.

[0035] In the illustrative embodiment shown in Fig. 1, the controller 50 is coupled to the pump devices 22, 32 and controllable valves 26, 36 and configured for selective and controllable operation thereof in order to direct flows of the first and second ingredients 20, 30 into the cavity 11. In some embodiments, a control panel, switch, or other control device 52 is also coupled to the controller 50 for a user to adjust operation of the mixing system 10. The control components 22, 26, 28, 32, 36, 38 are configured to be manually adjusted and/or actively controlled by the controller 50 to modify the flows and dispensing of ingredients 20, 30 into the cavity 11 for mixing. In some embodiments, one or more sensors or detectors 54, 56, 58 are coupled to the mixing device 12 for detecting one or more of the concentration, Brix, specific gravity, conductivity, or other measurable characteristics of the ingredients 20, 30 and/or mixture 40 at one or more locations to provide information to the controller 50 for controlling operation of the mixing system 10. For example, if the concentration or other characteristics of the mixture 40 as sensed by the sensors 54, 56, and/or 58 indicates that more of the first ingredient 20 (e.g., juice concentrate) is needed, the pump device 22 and/or controllable valve 26 can be adjusted to allow more of the first ingredient 20 to flow into the first inlet 15. Alternatively, the pump device 32 and/or controllable valve 36 can be adjusted to allow less of the second ingredient 30 to flow into the second inlet 16.

[0036] In use, the first ingredient (e.g., juice concentrate) is introduced through the first inlet 15 and forced to flow past the openings 63 of the second inlet 16 to be impacted, collided with, or otherwise impinged on by the second ingredient 30 flowing from the second inlet 16 into the cavity 11 to form the mixture 40. The mixture 40 tends to flow along the flow path 19 through the cavity 11 toward the outlet 17. Some mixture 40 may develop in the chamber at the upstream end of the cavity 11 and is generally forced to flow along the flow path 19 against the flow of the second ingredient 30 by the incoming stream of the first ingredient 20.

[0037] Another embodiment of a mixing device 112 in accordance with the present disclosure is shown in Figs. 2-4. The mixing device 112 is configured to receive flows of first and second ingredients 120, 130, such as juice concentrate and water, to form a mixture 140 thereof, such as a beverage, similar to the mixing device 12 of Fig. 1, and similar numbers in the 100's are used to identify portions similar to those of mixing device 12. The mixing device 112 includes a body 114 defining an internal cavity 111, a first inlet 115 in fluid communication with the cavity 111, and an outlet 117 spaced apart from the first inlet 115 and in fluid communication with the cavity 111, and a second inlet 116 coupled to the body 114 and extending into the cavity 111 (Fig. 10) from a proximal end adjacent the outlet 117 to a distal end adjacent the first inlet 115 to define a flow path 119 through the cavity 111 from the first inlet 115 to the outlet 117. In some embodiments, the body 114 defines a channel 172 extending between the outlet 117 and a hub 176 of the body 114 to pass the mixture 140 exiting the cavity 111 through the outlet 117 to an outlet passage 178 coupled, for example, to a dispensing head for delivery of the mixture to a container, such as a cup, pitcher, or other container for further dispending or consumption of the mixture (e.g., finished beverage produced).

[0038] In the illustrative embodiment, as shown in Figs. 2-4, a fitting 123 is coupled to the first inlet 115 and sealed against the body 114 (e.g. by an O-ring) as part of an inlet passage for the first ingredient 120. A plate 108 secures to the body 114 with a fastener 173 to hold the fitting 123 in the first inlet 115. In some embodiments, the body 114 defines a seat 133 adjacent to the outlet 117 and configured to receive the second inlet 116. A gasket 181 engages with the second inlet 116 and the body 114 to form seals therewith. In some embodiments, a pump device 136 is coupled to the seat 133 and configured to direct a flow of the second ingredient 130 into the second inlet 116. In some embodiments, a flow regulator or flow control assembly 138 is coupled to a chamber 135 of the body 114 and configured to allow for adjustment of the flow of the second ingredient 130 to the pump device 136 through a channel 137 extending between the chamber 135 and the seat 133. For example, the exemplary pump device 136 includes a pump portion 180, a head portion 182 coupled to the pump portion 180, and a protruding portion 186 extending from the head portion 182. One or more holes 184 in the head portion 184 allow the second ingredient 130 flowing though the channel 137 into the seat 133 to pass into the pump portion 180, and one or more holes 188 in the protruding portion 186 allow the second ingredient 130 flowing through the pump portion 180 to pass into the second inlet 116. The head portion 182 is sealed against the seat 133 (e.g. by an O-ring), and the protruding portion 186 extends into the second inlet 116 (Fig. 10) and is sealed against the second inlet 116 (e.g. by an O-ring). A plate 178 of the pump device 136 is secured to the seat 133 with fasteners 179. A plate 175 secures to the chamber 135 with fasteners 177 to hold the flow regulator 138 in the chamber 135.

[0039] The exemplary second inlet 116 is shown in further detail in Figs. 5-9. The second inlet 116 includes a base 160, a neck 162 extending from the base 160, and a post 164 extending from the neck 162 at a proximal end to a distal end spaced apart from the neck 162. The base 160, neck 162, and post 164 are arranged concentrically along an axis A (Fig. 9). In the illustrative embodiment, the base 160 has a first outer diameter, the neck 162 has a second outer diameter smaller than the first diameter, and the post 164 generally has a third outer diameter smaller than the second diameter. In some embodiments, the post 164 has an outer tapered profile reducing in diameter as the post 164 extends farther away from neck 162. The base 160, neck 162, and post 164 are generally annular (with the distal end of the post 164 closed) to define an internal passageway 161 of the second inlet 116. The base 160 defines a port 165 opening into the internal passageway 161. In the illustrative embodiment, a pair of openings 163a, 163b in fluid communication with the internal passageway 161 and arranged adjacent to a distal end of the post 164 opposite of the neck 162. In some embodiments, a circumferential groove 151 (shown in phantom in Fig. 9) is formed around the base 160. In some embodiments, a further opening 153 (shown in phantom in Fig. 9) extends through the distal end of the post 164 to provide a flow of the second ingredient 130 into the chamber at the upstream end of the cavity 111 for pre-mixing of the first and second ingredients 120, 130. In some embodiments, the neck 162 is omitted, and the post 164 extends from the base 160.

[0040] The openings 163a, 163b each generally provide a circumferential spray (flow) of the second ingredient 130 around the second inlet 116 for thorough mixing with the first ingredient 120 in the cavity 111 and dissolution of particulates. In some embodiments, the openings 163a, 163b together provide a substantially uninterrupted spray of the second ingredient 130 circumferentially around the second inlet 116 (when viewed along the axis A) such that substantially all of the first ingredient 120 flowing through the cavity 111 is impinged by the flow of the second ingredient 130. In some embodiments, the openings 163a, 163b are configured to discharge the second ingredient 130 in a fan spray pattern extending circumferentially and along a substantially radial direction. In some embodiments, the pair of openings 163a, 163b together provide a flow of the second ingredient 130 substantially 360 degrees around the second inlet 116 (e.g., around the axis A) such that substantially all of the first ingredient 120 flowing through the cavity 111 is impinged by the flow of the second ingredient 130. In some embodiments, a portion of the spray provided by one opening 163a circumferentially overlaps with a portion of the spray provided by the other opening 163b. In some embodiments, the openings 163a, 163b together provide a flow of the second ingredient 130 between about 315 degrees and about 405 degrees around the second inlet 116. While two openings 163a, 163b are shown, three or more openings are used in some embodiments, with each opening providing a spray of the second ingredient 130 around respective circumferential (or partially overlapping) portions around the second inlet 116.

[0041] In the illustrative embodiment, the openings 163a, 163b are arranged at a substantially similar axial location along the post 164 and each opening 163a, 163b extends axially and circumferentially along the post 164 to define arcuate slots as shown in Figs. 5-9. The openings 163a, 163b generally divide the post 164 into a first section 167 (extending between the openings 163a, 163b and the neck 162) and a second section 169 (extending from the openings 163a, 163b to the distal end of the post 164) coupled together by bridges 166a, 166b extending between axially-offset circumferential ends of the openings 163a, 163b. In some embodiments, the second inlet 116 is a unitary and integral structure. In some embodiments, the second inlet 116 is formed by an injection molding process. In some embodiments, the openings 163a, 163b widen as they extend through the post 164 from a radially inward position (e.g., at the internal passageway 161) to a radially outward position (e.g., at an exterior surface of the post 164). In some embodiments, the openings 163a, 163b extend substantially circumferentially and are axially and/or circumferentially offset to provide connecting structures between the first and second sections 167, 169.

[0042] The second inlet 116 is shown extending into the cavity 111 to define the flow path 119 in Fig. 10. The second inlet 116 is sealed against the body 114 with the gasket 181 that extends around the neck 162. The protruding portion 186 of the pump device 136 extends through the port 165 into the base 160 of the second inlet 116 for the flow of second ingredient 130 into the internal passageway 161. The first and second ingredients 120, 130 flow through the cavity 111 and combine into the mixture 140 for discharge through the outlet 117.

[0043] In some embodiments, the second inlet 116 is provided as a retrofit kit. For example, some existing mixing devices 1012 include a body 1014 (defining an internal cavity 1011, a first inlet 1015, and an outlet 1017) and a second inlet 1016 coupled to the body 1014 and extending into the cavity 1011 to define a flow path 1019 through the cavity 1011 as shown in Fig. 15. The second inlet 1016 includes a base 1060 and a post 1064 extending from the base 1060 as shown in Fig. 16. The second inlet 1016 is generally hollow to define an internal passageway 1061, and an opening 1063 is arranged at a distal end of the post 1064 and angled upward. A protrusion 1055 extends radially outward from an upper side of the post 1064 downstream from the opening 1063. A detent 1057 engages with a notch (not shown) in the body 1014 to orient the opening 1063 toward the first inlet 1015. The base 160 and neck 162 of the exemplary second inlet 116 can have substantially the same outer diameters as the base 1060 and post 1064 of the existing second inlet 1016, respectively, such that the second inlet 116 can be used in place of the existing second inlet 1016 without significant modification of other components in the mixing device 1012 (such as the gasket 1081, cavity 1011, or other mating components (e.g., a pump device)). In some embodiments, a retrofit kit includes a second inlet in accordance with the present disclosure, such as the second inlet 116, and one or more replacement sealing components, such as the gasket 1081. In some embodiments, the retrofit kit excludes the replacement sealing components.

[0044] The second inlet 116 of the present disclosure also has several benefits over the existing second inlet 1016. For example, the additional reduced diameter of the post 164 compared to the post 1064 provides a wider flow path 119 (e.g., an increased distance between the outer surface of the post 164 and inner surface of the cavity 111) to allow larger particles to pass and minimize clogging of the mixing device 112. The lack of protrusion 1055 also allows the mixture 140 to flow around a greater extent of the second inlet 116 to maximize mixing of the ingredients 120, 130. As shown in Figs. 17 and 18, the existing second inlet 1016 directs flow through the opening 1063 toward the first inlet 1015 forcing the ingredients into the upstream end of the cavity 1011 for mixing primarily by swirling within the cavity. The gradient lines show the relative velocity of the flows within the cavity (listed values are in inches per second). By contrast, as shown by the relative flow velocities in Figs. 19 and 20 (listed values are in inches per second), the second inlet 116 of the present disclosure primarily directs the flow of the second ingredient 130 radially outward to impinge on the flow of the first ingredient 120 passing the openings 163a, 163b and providing cutting/shearing forces for improved mixing and breakdown of particulates. The lack of detent 1057 also allows the second inlet 116 of the present disclosure to be inserted into the cavity 111 in any rotation orientation about the axis A without regard for the direction of the openings 163a, 163b relative to the first inlet 115.

[0045] Another embodiment of a mixing device 212 in accordance with the present disclosure is shown in Figs. 11 and 12. The mixing device 212 is configured to receive flows of first and second ingredients, such as juice concentrate and water, to form a mixture thereof, such as a beverage, similar to the mixing device 112 of Figs. 2-10, and similar numbers in the 200's are used to identify portions similar to those of mixing device 112 with the associated description thereof applying equally to the mixing device 212. At least one difference includes the addition of a second pair of openings 263c, 263d spaced axially closer to the neck 262. The openings 263a, 263b, 263c, 263d generally divide the post 264 into a first section 267a (extending between the openings 263c, 263d and the neck 262), a second section 267b (extending between the openings 263c, 263d and the openings 263a, 263b), and a third section 269 (extending from the openings 263a, 263b to the distal end of the post 264) coupled together by bridges 266a, 266b, 266c, 266d extending between axially-offset circumferential ends of the openings 263a, 263b, 263c, 263d.
