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.
An example of such a passive mixing device might be a venturi mixing apparatus in which two ingredients or components are brought together to produce a final mixed product. In a venturi device a stream of diluent, such as water, flows through a water feed line. Water flow is restricted and then expanded to produce a desired flow characteristic. On the expansion side of the venturi device is a connection to a second component. For example, the second component may be a beverage concentrate. The beverage concentrate connection or tube is connected to and communicates with the expansion side of the venturi device. When water flows through the water line and flows through the venturi device the venturi device creates a vacuum on the second component line thereby drawing second component from its source or container.
Another example of a passive mixing device occurs in the beverage industry in which concentrate is mixed with water by use of two separate lines and corresponding controllable valves. For example, the controllable valves are operated to allow the diluent, such as water, to be dispensed and a second component, such as a beverage concentrate, to be dispensed into the water stream. The water and beverage concentrate can be pumped to the valve, pressurized, fed by gravity or otherwise delivered to the corresponding valve. When the valves are activated, the ingredients or components come together for mixing in a passive manner. The combined stream produces some degree of turbulence thereby mixing or at least combining the components.
Examples of active mixing may include dispensing ingredients into a conical mixing chamber that may include rotating blades or other agitators. While mechanical mixing is essential in some situations, it requires additional time and effort to periodically cleanse the mechanical mixing components. Additionally, the use of mechanical mixing components results in a more complex and, possibly, more expensive system. Further, the use of mechanical mixing or active mixing components often requires a cleansing cycle. The clean-out cycle often involves rinsing the system with the diluent at the end of a dispensing cycle. The dispensing of the diluent such as water at the end of a dispense cycle may not be preferred because it adds a very diluted juice on the top of the cup. This may appear to the consumer as an improperly mixed solution or over diluted solution. In some situations the user or consumer of the product may find this rinsing unattractive or question whether their product is being over diluted or improperly diluted or watered-down.
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.
Additional features will become apparent to those skilled in the art upon consideration of the following detailed description of drawings exemplifying the best mode as presently perceived.
The description particularly refers to the accompanying figures in which:
While the present disclosure may be susceptible to embodiment in different forms, there is shown in the drawings, and herein will be described in detail, embodiments with the understanding that the present description is to be considered an exemplification of the principles of the disclosure and is not intended to limit the disclosure to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings.
With reference to
The body 22 includes a first inlet 28 communicating with the cavity 26 and through which at least one first ingredient, for example, juice concentrate 30 is dispensed into the cavity. An outlet 32 also communicates with the cavity 26 and is positioned spaced apart from the inlet 28. Concentrate 30 is introduced through the inlet 28 for mixing with a second ingredient, for example, water 34 which is introduced through a second or water delivery inlet 38. The concentrate 30 and water 34 flow into the chamber 26 for mixing therein.
Water 34 is introduced into the cavity 26 by a water delivery inlet 38. The inlet 38 includes a passage 40 defined in the illustration as a tube which has a dispensing end 42. The dispensing end 42 has at least one opening 43 through which water is dispensed. The opening 43 is positioned at or proximate to the dispensing end 42. The dispensing end 42 and at least one opening 43 are to be broadly interpreted and are not limited to the specific construction shown and described herein. The dispensing end 42 is positioned in the cavity 26 generally spaced between the inlet 28 and the outlet 32. Further, in at least one embodiment, the dispensing end 42 is positioned generally downstream of the inlet 28 and generally upstream of the outlet 32.
As used throughout, various terms are intended to be broadly interpreted. In this regard, the term “concentrate” is intended to be broadly interpreted as a second 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 device, system and apparatus for mixing as disclosed herein. Similarly, the term “diluent” or “water” is intended to be broadly interpreted as a first ingredient which in one embodiment is water. While the present disclosure uses the term “water” and “diluent” generally interchangeably, it is anticipated that a variety of diluent materials may be used to produce a variety of beverage products. For example, diluent may be another ingredient such as another flavor or base ingredient other than water. Further, the diluent could be another form of ingredient such as, liquid gel, gas, ice crystals, or any other substance that is mixed with at least one other substance to produce the desired resultant product.
In at least one embodiment, a chamber 50 is defined within the cavity 26. The chamber 50 is generally positioned proximate to the inlet 28 and the dispensing end 42 of the water inlet 38. The chamber 50 is generally positioned spaced from and generally at least partially in opposition to the dispensing end 42 of the water inlet 38. The chamber 50 is positioned in any position to receive the first and second ingredients. As such, when water 34 is dispensed through the water inlet 38 and out through the end 42, water is directed toward the chamber 50. Also, the chamber 50 is generally positioned upstream of the flow out of the chamber 50 or generally out of the direct flow path of concentrate 30 flowing through the inlet 28. The position of the chamber 50 relative to the inlet 28 and dispensing end 42 results in some volume of concentrate 30 and water 34 being pushed or flowed into at least a portion of the chamber 50 for mixing within at least a portion of the chamber 50 before it is allowed to flow downstream toward the outlet 32.
The inlet 28, opening 43 of dispensing end 42 and the outlet 32 are shown in general diagrammatic form. For example, the inlet 28 and outlet 32 are generally shown as circular or otherwise tubular passages through which fluid can flow. Similarly, opening 43 of dispensing end 42 is shown as the reduced diameter tip of the tube at the dispensing end 42 of the delivery inlet 38. Each of these passages or tubes can be configured in any variety of forms to achieve a desired result. The diagrammatic embodiments are provided by way of illustration and are not intended to be limiting. For example, the opening associated with the inlet 28 and the outlet 32 may be in a flare outwardly or inwardly to produce a desired flow characteristic. For example, the concentrate entry point may be a reduced diameter relative to the diameter of the corresponding flow path 45 to change the flow characteristics of the concentrate 30 introduced into the device. Similarly, the outlet 32 may include an increased diameter opening in a corresponding tube 47 so as to facilitate draining, streamlining, columnating or otherwise making the fluid flow exiting the device flow in a predetermined manner, for example more cohesive or less cohesive. It is expected that these variations and other variations which are inspired by the present disclosure are within the scope of the present disclosure.
The present configuration of the device 20 prevents only a direct, gravity-induced fall of concentrate 30 and water 34 through the body 22 to the outlet 32. Rather, the flow action of the pressurized water from the dispensing end 42 directed toward the flow of concentrate 30 through the inlet 38 causes a driving or forcing of the water 34 and concentrate 30 into the chamber 50 for mixing. The pressurized water (a first ingredient) impinging on the concentrate (a second ingredient) causes mixing of the two ingredients in a manner not known in the prior art. This general concept applies to this disclosure regardless of the type and characteristics of the two or more ingredients mixed or the structure or orientation of the device used to mix the two or more ingredients. The force of the pressurized water impinging on the concentrate flow will cause the water and concentrate to mix. The chamber 50 has an end 52 which does not allow water and concentrate to flow there beyond. The directional flow of pressurized water 34 from the dispensing end 42 and the generally positively pressurized flow of concentrate 30 through the inlet 28 result in an accumulation of ingredients in the chamber 50. While it is mentioned that the flow of concentrate 30 through the inlet 28 is generally positively pressurized, it is expected that a gravity flow of concentrate 30 will also function in this application. The gravity flow also produces some degree of pressurization as a result of the influence of gravity on the concentrate flow and this embodiment is included in this disclosure.
Eventually, the accumulation in the chamber 50 is a volume which is greater than the volume of the chamber 50. This occurs when the pressure in the chamber exceeds the forces associated with the inlet flow of the pressurized water 34 from the dispensing end 42 and the inlet flow of the concentrate 30 through the inlet 28. At this point, a mixture 54 of concentrate and water will tend to flow 56 away from the chamber 50 and toward the outlet 32. The mixture 54 will continue to mix as it continues to flow 56 toward the outlet 32 whereupon it is dispensed as a generally integrated, homogeneous product, in this case a beverage 36.
The consistency of the beverage is a result of the physical agitation impact, or collision of the mixture 54 in the chamber 50 and flow 56 through the cavity 26. The mixture 54, once mixed in the chamber, 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 32. As the volume of the chamber 50 is finite and water 34 and concentrate 30 continue to flow therein, the mixture 54 will tend to accumulate. The consistency of the beverage 36 may be, at least in part, due to the dissolution of the concentrate 30 into the water 34. This is in contrast to prior art mixing devices which merely may have combined the ingredients, yet not caused the concentrate 30 to dissolve, combine or otherwise transform into solution with the water 34 creating a generally homogeneous beverage 36.
The homogeneity of the beverage 36 can be tested by a Brix Scale measurement or Brix measurement. Preliminary tests show that the beverage 36 dispensed through the outlet 32 provides a consistent Brix measurement throughout different levels of a beverage volume dispensed into a container. Prior art devices may exhibit noticeably defined changes or variations in Brix measurements at different levels in the same container. In other words, the concentrate and the diluent or water are not thoroughly mixed or integrated. In contrast, the present mixing method and device causes the concentrate 30 to be thoroughly mixed in the water 34 creating a generally homogeneous beverage 36 as measured by the Brix measurements in a standard container. In contrast, the prior art devices dispensing beverage into the same container resulted in a change in the Brix measurement from the bottom of the container toward the top of the container. The variations in the Brix measurement are an indication that the beverage has not been thoroughly mixed and that, at least some portions of concentrate may not have been integrated or dissolved into the solution.
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. For example, while the general parameters of an inlet 28 communicating with the cavity 26 and an outlet 32 also communicating with the cavity 26 can be found in various embodiments, the generally horizontally, or at least partially horizontally, oriented configuration of these components will be used in various embodiments as well. Similarly, it is believed that the configuration of the chamber or holding area 50 providing a dead-end or cul-du-sac area in which water 34 and concentrate 30 collide and impinge upon each other to cause mixing is found in other configurations based on the concepts taught herein.
The flow of water and concentrate into the body 22 can be accurately controlled for controlled mixing by use of mixing control components 51. The mixing control components are to be broadly interpreted but may include, by way of example and not limitation, such components as a controllable inlet valve 53 on the water line and a controllable inlet valve 55 on the concentrate line. Further, a flow regulator 57 may be used on the water inlet line and a flow regulator 59 may be provided on the concentrate inlet line. The controllable valves 53,55 may be coupled to a controller 61 having a control panel, switch or other control device 63 also coupled to the controller. Additionally, pumping devices 71,75 or other flow pressurizing or accelerating devices may be coupled to the controller 61 for further control of the components. These flow control components 57 help to achieve the required or preferred mix of concentrate and water.
These components 51 can be actively controlled to modify the flow and dispensing of water and concentrate into the body 22. In this regard, one or more mixture sensors or detectors 65, 67, 69 may be positioned in the device or proximate to the device as necessary for detecting one or more of the concentration, Brix, specific gravity, conductivity or other measurable characteristics of the mixture at one or more locations to provide information to the controller 61. The sensors provide information which can be used by the controller to modify the operation of the components such as the control valves 53,55, pumps or other devices which are controllable and may have an effect on the resultant product 36. For example, if the concentration or other characteristics of the mixture as sensed by the sensors indicates that more concentrate is needed, the controllable valve 55 may be opened to allow more concentrate to flow. Alternatively, the pump 71 coupled to the controller 61 may be operated to increase the pumping rate to deliver more concentrate 30 from the ingredient or concentrate source 73. Similarly, the rate of pumping of a pump 75 communicating with the inlet line and coupled to the controller 61 may be reduced so as to reduce the quantity of water flowing into the inlet line.
It should be noted that the system as described above may include all of the aforementioned additional components or none of the components. In its simplest embodiment the device 20 includes the inlet line 38, inlet line 45 and body 22. The water inlet line 38 is a second ingredient source, in this case water, coupled to a pressurized or gravity fed source and the concentrate is coupled to a pressurized or gravity fed source. Desired pressures are provided to produce the desired result. However, more complicated variations may be provided by combining the simplest form with one or more of the aforementioned components. It is also envisioned that other components may be added to various embodiments to provide additional control, sensing, quality or other characteristics of the resultant beverage.
In its simplest form, the device eliminates extra components, parts or structures used for mixing. In the more complicated form the device provides increased control and accuracy of mixing. The resultant beverage is produced consistently and is mixed properly to produce a desired end product.
It is anticipated that the general principles are covered hereunder as well as all the other various modifications and variations that can be conceived by one of ordinary skill in the art having been taught the principles herein. For example, the dispensing end 42 can be a nozzle to provide a defined flow configuration such as in the form of a fan, ring, point or any other dispensing end 42 and associated opening 43 or openings configuration. A variety of dispensing ends 42 may be used to achieve specific results depending on the mixing conditions and the components used in the mixing operation and the ingredients, such as concentrate 30 and water 34, used in the mixing method. The nozzle or dispensing end 42 generally creates an upstream flow having a flow generally directed into the chamber 50. In at least one configuration, the dispensing end or nozzle 42 is configured to provide a jet action of measurable force. In this embodiment, the flow of the water causes movement of the concentrate 30 dispensed through the inlet 28 into the chamber 50 for subsequent agitation and mixing to form the mixture 54.
It is also envisioned that a variety of configurations of the chamber 50 are included within the scope of this disclosure. While a generally tubular, rounded, dead-end configuration is provided for the chamber 50, it is envisioned that various cross-sections, end 52 configurations and other features may be incorporated into the chamber 50 to provide the desired mixing effect depending upon the specific conditions used in the mixing method. Similarly, the configuration of the body 22 defining the shape, volume and surface features of the cavity 26 is to be broadly interpreted to include various embodiments. Likewise, the configuration, angular orientation, size, dimension, flow rate and other characteristics associated with the inlet 28 and the outlet 32 are envisioned to be broadly interpreted.
Consistent with the broadening of the various terms and characteristics of the present device, method and system, the introduction of water through the inlet 38 is shown as being positioned towards an end 62 generally positioned opposite the chamber 50. The inlet 38 could be introduced into the cavity 26 through the body 22 at various portions along the wall 24. Also, the position of the nozzle 42 in the cavity 26 can be adjusted to produce desired mixing results. In this regard, the nozzle 42 can be positioned upwardly, downwardly or angled towards or angled away from the inlet 28. As will be described in greater detail below with regard to
The mixing device of this disclosure can be configured in a cascading arrangement as shown in
The cascading or serial configuration, with or without the pump 80, may be useful in situations in which a high density concentrate 30 may require mixing with water having an elevated temperature to produce a desired beverage or secondary concentrate result. It is envisioned that multiple cascading configurations which might have different characteristics can be used to produce a desired resultant beverage.
The present device also includes benefits with regard to concentrates which might include fibrous material. For example, some orange juice and other citrus juice concentrates may include relatively high levels of fibrous content or pulp. In prior art mixing devices, juice concentrate containing fibrous material may accumulate within the mixing device clogging the flow path in the system. In the present device, the surfaces are generally smooth and continuous allowing for easier, more efficient cleaning and sanitizing. In this regard, during a cleaning cycle, cleaning material could be introduced through the inlet 28 and agitated in the same manner as when diluting a beverage concentrate. In this regard, the water 34 can be adjusted to a desired flow rate for mixing with sanitizing solution introduced through the inlet 28. The mixture then flows through the cavity 26 cleansing the interior surfaces of the cavity. The cleansing material flows through the outlet 32 for thorough cleaning of the mixing device.
Additionally, the device 20 can be configured to remove the body 22 to facilitate cleaning. This can be achieved in any one of many configurations which will allow disengagement of the body 22 from the dispensing device with which it may be used. If the body 22 is removable it can be placed into a sanitizing or dishwashing system to sanitize all the appropriate surfaces. Such a configuration may require a removable connection between the inlet passage 45 and the body 22 or may include a portion of the tube 45 and the outlet tube 47. It is anticipated that it may be preferable to allow one of the ends 52,62 to be removable so as to allow water to flush through the tube 22 defining the body. It is expected that many configurations can be developed which will allow the device to be removed from the machine for cleaning. Such developments might also include quick release connectors between the tube 47 and the tube 45, as well as a quick release between the water line 38 and the system. Further, it is envisioned that the body 22 could be separated at some location between the ends 52,62 to allow each portion to be placed into a cleaning or sanitizing system for thorough cleansing of the corresponding portions of the chamber 26.
In use, concentrate is introduced through the inlet 28 and impacted, collided with or otherwise impinged or impacted by pressurized water 34 flowing from the dispensing end 42. The water and concentrate 30 form a mixture 54 which backs up in a dead end chamber 50. The chamber 50 is positioned generally upstream from the outlet 32 and proximate to the inlet with the inlet 28 being positioned between the dispensing end 42 and the primary volume of the chamber 50. During the mixing method, the system and apparatus cause a volume of mixture 54 to back up in the chamber 50.
At a point when the volume and pressure created by the mixture 54 in the chamber 50 is greater than the flow rate of the flow path of water 68 flowing into the chamber 50, in combination with the volume and flow pressure of the juice concentrate 30 flowing therein, the mixture 54 tends to flow along the flow path 56 through the cavity 26. In this regard, the buildup of mixture 54 in the chamber 50 reaches a point where no additional mixture can accumulate in the chamber, the volume of the mixture 54 exceeds the volume of the chamber 50, and the mixture flows against the opposing flow 68 of water 34 from the water inlet 38. The mixture having the concentrate thoroughly combined in solution with the water flows through the outlet 32.
It is envisioned that the mixing device 20 as disclosed herein may also be provided as a kit for use with existing machines or to retrofit existing machines. In this kit, the device 20 can include a connection between the inlet tube 38 and the existing water line. Additionally, the inlet 28 can be coupled to an existing concentrate dispensing line. In this manner, the device 20 can be used with a variety of existing or yet to be designed beverage dispensers. The overall configuration of the device 20 can be adjusted or modified to accommodate the particular characteristics, inputs and desired outputs of the beverage dispenser.
With reference to
It is envisioned that multiple water inlets 38a, 38b may be used to increase the mechanical combination or agitation of the water with a single stream of concentrate. Also it is envisioned that a single water inlet may be used to combine two different flavors or two identical flavors of concentrate flowing in through the multiple inlets 30a, 30b. With the foregoing in mind, there may be advantages to introducing smaller streams of identical concentrate flavors from two different directions so as to further result in combination with the dilution water.
As shown in FIGURES in 5-8, an exterior surface 86 of the inlet 38d includes a series of protrusions 88. The protrusions as shown are in the form of ribs which are positioned generally spirally about the exterior surface 86. While ribs are shown it is intended that a broad interpretation of the protrusions 88 is included in this disclosure. The pattern of the ribs as shown provides the structures which interrupt or disrupt an otherwise generally smooth flow path along the exterior surface 86 of the inlet 38d. Additionally, similar protrusions can be added to the interior surface 84 of the body 22. The function of the protrusions whether on the exterior surface 86 of the inlet 38d, interior surface 84 of the body 22 or any combination of such structures is to disrupt and increase turbulence in the flow of the mixed concentrate and water as it flows from the chamber 50 towards the exit 42.
Additionally, as shown in
In
It should also be noted that all of the aforementioned variations of the device, system and method as described hereinabove with regard to
A controllable valve 112 and inlet 38 are retained on the body 22 by a retaining clamp 114 and corresponding screws 116. Water is introduced into the body 22 through the water control fitting assembly 120. Water is introduced into a primary chamber 122 that communicates with a secondary chamber 124 that communicates with the inlet 38. Operation of the controllable valve 112 opens and closes against a rear portion 128 of the inlet 38 by means of moveable stopper 130. The inlet water assembly 120 is pressurized thereby allowing positive flow of water through the primary and secondary chambers 122, 124 when the valve 112 is operated over lines 118 by a controller.
The water inlet assembly 120 includes a flow control assembly 132. The flow control 132 assembly includes an O-ring 134 on a sleeve 136. A flow control piston 138 is retained in the sleeve. Flow control spring 140 acts against the piston 138. Another O-ring 142 is carried on an adjuster bonnet 144. The adjuster bonnet 144 is engaged in the bore 146 of the primary chamber 122. An O-ring 148 and positioned adjuster 150 is engaged with the bonnet 144 with the entire assembly being retained in place by a bracket 152 attached to the body with screws 154. Flow control assembly 132 allows for adjustment of the flow of the water attached to the feed side 160 of the primary chamber 122.
The structures as disclosed in
As shown in
As shown in
With further reference to
As shown in
In the embodiment as shown in
In use, the user attaches the device 220 to the tube 232 and to the BIB 230. Additionally, the assembly may come preassembled with the tube 232 along with means for restricting or permitting flow through the tube. For example, the tube could be clamped shut during shipment whereupon a clamp is released from the tube 232 to allow flow through the tube. Additionally, while the tube 232 is shown as a rather short section, the tube can be an elongated section of a flexible tube which might be used in combination with a peristaltic pump or other pumping device. In this manner, the elongated tube can be installed or otherwise engaged with the pumping mechanism. This type of configuration will facilitate an easy and efficient installation in a sanitary manner. None of the structures or devices need to be opened and there is no contact between the concentrate retained within the BIB, tube and mixing device.
With regard to
While three different inlet port locations are shown, 300, 302, 304, any number of inlet ports may be used, and any variety of locations may be used. The inlet ports 300, 302, 304 shown in
For example, the inlet ports, 300, 302, 304 may be used to inject or introduce a distillate to a mixture. For example, when a tea concentrate dispensing system tea concentrate 30 may be introduced into the chamber for mixing with water 68 to produce a tea product 54. However, additional dilution may be required and as such the product 54 can flow into a second mixing device 20a. Whereas the first mixing device 20 may have introduced a heated water or dilution material, the second mixing device 20a may introduce a cool or unheated water or dilution material. The product of the second mixing chamber 54a may be the final product or may be the final produce before introduction of a distillate. The distillate provides additional flavor, aroma, and other beverage characteristics which may not be found or may not be as prominently expressed in the concentrate or the dilution materials. As such, such a distillate may enhance the beverage experience. The introduction of the distillate may depend on such conditions such as the temperature of the beverage product or the timing of the beverage product as well as any number of additional conditions. As such, such inlet ports may be needed to be placed at any one or more locations throughout the dispensing process. All of the various locations of the inlet ports 300, 302, 304 and any other desired or preferred location is within the scope of this disclosure.
