     TECHNICAL FIELD OF THE INVENTION 
     This invention relates to product dispensers, and in particular, relates to systems and methods for priming or purging a product dispenser. 
     BACKGROUND OF THE INVENTION 
     Conventional product dispensers can pour a beverage by combining a syrup, sweetener, and/or water. To create a finite variety of beverage selections different kinds of syrup can be offered. This typically results in being able to offer a finite number of branded and non-branded beverage selections. As an example, a single prior art dispenser using several different kinds of syrup might be able to offer limited choices of COCA-COLA™, DIET COCA-COLA™, SPRITE™, and a few other branded or non-branded beverage selections. 
     One problem with these types of conventional product dispensers is that only a limited number of drinks can be offered. As such, conventional product dispensers may be limited in being able to offer the consumer what they want. In this regard, consumers want a wider menu of beverage selections and the ability to customize their beverage. Research suggests that they want more beverage variations even for a traditional branded beverage. For example, offering COCA-COLA™, COCA-COLA™ with lime, CHERRY COCA-COLA™, VANILLA COCA-COLA™ and numerous other types of COCA-COLA™ beverage variations. Offering all the variations possible for a single drink brand such as COCA-COLA™ are impractical in conventional product dispensers in part because conventional product dispensers have limited capacity and selection capability. They may not offer the consumer what the consumer wants, that is, a complete variety of choices for all types of branded and non-branded beverages. 
     Product dispensers historically have worked by combining a diluent (such as water) with a beverage base. These beverage bases usually have a reconstitution ratio of about 3:1 to 6:1. The beverage bases usually come in large containers that require large amounts of storage space and may need to be refrigerated. These requirements often necessitate the need to store these containers far from the actual dispenser and to run long lines from the containers to the dispenser. 
     Given the improvements in shelf life and concentration described above, there is a desire for a product dispenser that can produce even more and different types of beverages while using a smaller footprint. This can be accomplished by breaking down the traditional beverage bases into constituent parts at much higher reconstitution ratios. These parts can then be stored in much smaller packages and stored closer to, adjacent to, or within the product dispenser itself. The product dispenser preferably can give the consumer multiple beverage options such that the consumer has the ability to customize his or her beverage as desired. 
     In certain instances, any number of beverages may become “sold out,” wherein the associated container for a particular beverage base or flavor becomes empty or near empty after the original amount of beverage base or flavor in the container is used. When a sold out condition occurs, an air pocket or air bubble may be introduced into a portion of an associated beverage supply line between the container and a dispensing nozzle. If a new container for the particular beverage base or flavor is connected to the beverage supply line, a product dispenser operator may have to “prime” the product dispenser to clear out the air pocket or air bubble from the portion of supply line. This can be performed by operating the product dispenser and selecting the particular beverage associated with the new container. In conventional product dispensers, the priming operation for each new container is a time consuming, manually initiated operation that requires the operator to individually prime each supply line for each newly installed container. In some instances, when multiple containers are installed, the priming operation for multiple containers can take several minutes since the operator must successively prime each container before the product dispenser is ready for further operation.

     The detailed description explains various embodiments of the invention, together with aspects and features, by way of example with reference to the drawings. 
     DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 
     As used herein, the terms “beverage forming dispenser”, “product dispenser”, “beverage dispenser”, “dispenser apparatus”, and “dispenser” refer to a device which dispenses a product such as a beverage, a fluid, or a consumable product. 
     As used herein, the terms “product” and “beverage”, and their pluralized forms, are used synonymously, and embodiments of the invention should not be limited in scope by the use of either term. 
     As used herein, the terms “prime” and “priming” refer to an operation used to clear out air, fluid, other substances or materials, or any combination thereof from a portion of supply line between a source and a dispensing nozzle. For example, priming or a prime operation can include introducing a fluid, for instance, a relatively small fluid amount of about 5 ml, into a supply line between a beverage source and a sensor disposed between the source and a dispensing nozzle, wherein the sensor can detect flow of the fluid introduced into the supply line. In certain instances, the sensor can detect a no or low flow condition in the supply line, a condition which may also be called a “sold out” condition. Upon or after priming or a prime operation, the sensor can detect fluid in the supply line, and thereby reset the sensor for subsequent detection of any no or low flow conditions. 
     As used herein, the terms “purge” and “purging” refer to an operation used to clear out air, fluid, other substances or materials, or any combination thereof from a supply line between a source and a dispensing nozzle. For example, purging or a purge operation can include introducing a fluid, for instance, a relatively larger fluid amount of about 60 ml, into a supply line between a beverage source and a dispensing nozzle, wherein the supply line is substantially filled with the fluid between the beverage source and the dispensing nozzle. In certain embodiments, purging or a purge operation can be used when ingredient sources are switched for a particular supply line, when the product dispenser is initially started upon installation of all new ingredients, when the product dispenser is initially started after manufacture for cleaning or testing, or to clear any shipping fluid from the supply lines. 
     Embodiments of the invention can include systems and methods for priming or purging a product dispenser. Certain embodiments of the invention can be particularly useful when operating a product dispenser, such as a beverage dispenser. In one instance, when an ingredient source is exhausted or otherwise depleted, air can be introduced into a portion of an associated supply line between the source and a dispenser nozzle associated with the product or beverage dispenser. In certain instances, a user or product dispenser operator may find it inconvenient to replace the ingredient source until multiple ingredient sources need to be replaced due to exhaustion or depletion. In this instance, the user or product dispenser operator may decide to replace the exhausted or depleted ingredient sources in a successive manner. Upon restart of the product or beverage dispenser, rather than successively prime each newly installed ingredient source and associated supply line, which can be time consuming, the user or product dispenser operator can use a one button prime command to simultaneously introduce a predefined amount of each ingredient into associated beverage supply lines between the newly installed ingredient sources and the dispenser nozzle, such as between the newly installed ingredient sources and a respective sensor. In this manner, any air or other substance that may be detected by a sensor associated with each supply line can be flushed out and replaced with relatively new ingredients from the newly installed ingredient sources, which can, in turn, reset the sensors and permit the product or beverage dispenser to dispense the newly installed ingredient sources. Thus, certain embodiments of the invention can provide a technical solution to the time consuming problem of successively priming the supply lines by flushing and replacing air from the supply lines in a product dispenser, such as a beverage dispenser. 
     In another instance, upon initial startup of a product dispenser, or in some instances, upon startup after prolonged maintenance, all new ingredient sources may be installed in a product dispenser. Rather than successively purge each newly installed ingredient source and associated supply line, which can be time consuming, the user or product dispenser operator can use a one button purge command, or a “Hyperstart”™ command, to simultaneously introduce a predefined amount of each ingredient into associated supply lines between the newly installed ingredient sources and the dispenser nozzle. In this manner, any air, shipping fluids, and/or sanitizing fluids, or relatively older ingredients within the supply lines can be flushed out and replaced with relatively new ingredients from the newly installed ingredient sources. Thus, certain embodiments of the invention can provide a technical solution to the time consuming problem of successively purging newly installed ingredient sources and associated supply lines in a product dispenser, such as a beverage dispenser. 
     The circumstances provided above are for illustration only, and are not intended to be limiting. One will recognize other circumstances for applying embodiments of the invention, and the applicability of those embodiments to other product and/or beverage dispenser technologies. 
     Turning now to the drawings in greater detail, in which like numerals indicate like elements throughout the several views,  FIG. 1  shows an example system such as a product dispenser  100  as is described herein. A user interface  110  may control some or all of the functional aspects of the product dispenser  100 . A consumer may select and/or create numerous types of beverages, blends, and additives using the user interface  110 . Furthermore, a food service employee and/or dispenser technician may use the user interface to implement certain installation and/or maintenance functions. A control device  120  may support the user interface  110 . The control device  120  may be a conventional microcomputer, processor, or a similar type of device. The control device  120  may be internal to or remote from the product dispenser  100 . 
     The product dispenser  100  may use any number of different ingredients. In this example, several different types of ingredients may be used: water (plain and/or carbonated) from a water source  130 ; macro-ingredients from a number of macro-ingredient sources  140 ; and micro-ingredients from a number of micro-ingredient sources  150 . Any number or combinations of sources  130 ,  140 ,  150  may be used herein. For example, it may not be necessary to have a macro-ingredient source, e.g., HFCS (High Fructose Corn Syrup), which is difficult to pump at high reconstitution ratios, may not be used. As such, only a diluent and a micro-ingredient source may be required. In another example, 106 unique ingredient sources  140 ,  150  may be present in a product dispenser, such as  100 , in accordance with an embodiment of the invention. One will recognize that other embodiments of the invention can include fewer or greater numbers of ingredient sources  140 ,  150 . 
     The water from the water source  130  may or may not be refrigerated. Other types of diluents may be used herein. A conventional carbonator or a similar type of device may be used to produce carbonated water as desired. The amount of carbonation may be varied. 
     Generally described, the macro-ingredients may have reconstitution ratios in the range of about 3:1 to about 6:1. The viscosities of the macro-ingredients typically range from about 100 centipoise or higher. Macro-ingredients may include sugar syrup, HFCS, juice concentrates, and similar types of fluids. Similarly, a macro-ingredient base product may include sweetener, acid, and other common components. The syrups, sweeteners, and base products generally can be stored in a conventional bag-in-box container remote from the dispenser  100 . The macro-ingredients also may be positioned within the product dispenser  100  itself. Any type of container may be used herein in accordance with embodiments of the invention. The macro-ingredients may or may not need to be refrigerated. 
     The micro-ingredients may have a reconstitution ratio ranging from about ten to one (10:1), twenty to one (20:1), thirty to one (30:1), or higher. Specifically, many micro-ingredients may be in the range of fifty to one (50:1) to three hundred to one (300:1). The viscosities of the micro-ingredients typically range from about 1 to about 100 centipoise or so. Examples of micro-ingredients include natural and artificial flavors; flavor additives; natural and artificial colors; artificial sweeteners (high potency or otherwise); additives for controlling tartness, e.g., citric acid, potassium citrate; functional additives such as vitamins, minerals, herbal extracts; nutraceuticals; and over-the-counter (or otherwise) medicines such as acetaminophen and similar types of materials. As described above, the acid and non-acid components of the non-sweetened concentrate also may be separated and stored individually. The micro-ingredients may be liquid, powder (solid), or gaseous form and/or combinations thereof. The micro-ingredients may or may not require refrigeration. Non-beverage substances such as paints, dyes, oils, cosmetics, etc., also may be used. Various types of alcohols may be used as micro or macro-ingredients. 
     In certain instances, the micro-ingredients and the micro-ingredient sources  150  may be positioned within or about the product dispenser  100  itself as opposed to being remotely positioned in conventional bag in box containers or otherwise. By being positioned about the dispenser, the micro-ingredient sources  150  can, for example, be positioned in close proximity to the dispenser  100  such as adjacent thereto, underneath, or in other near by positions. Any other type of storage arrangements may be used in accordance with embodiments of the invention. The macro and/or micro-ingredient sources may optionally be located remotely from the dispenser  100 , such as in a back room, connected to the dispenser  100  with conventional tubing. Furthermore, any type of container may be used herein in accordance with embodiments of the invention. 
     The water source  130 , the macro-ingredient sources  140 , and the micro-ingredient sources  150  each may be in communication with a respective pump  160 , sensor  165 , and/or a metering device  170  via a respective supply line  175 . The control device  120  may control the pumps  160 , sensors  165 , and metering devices  170 . Generally described, the water source  130  and the macro-ingredient sources  140  each may be in communication with one of the pumps  160 . The pump  160  may be a conventional solenoid pump or a similar type of device. 
     The micro-ingredient sources  150  each may be in communication with a respective metering device  170  via a respective supply line  175 . The metering device  170  may be a positive displacement pump or a similar type of device. Such a positive displacement pump provides portion control for the more highly concentrated micro-ingredients. An example of the operation of a positive displacement pump is shown in commonly owned U.S. patent application Ser. No. 11/276,548, entitled “Pump System with Calibration Curve” incorporated herein by reference. 
     For example, the positive displacement pump may be a solenoid pump, a gear pump, an annular pump, a peristaltic pump, a syringe pump, a piezo pump or any other type of positive displacement device that is designed to pump a fixed displacement for each pump cycle. 
     The pumps  160 , sensors  165 , and the metering devices  170  may be in communication with a dispensing nozzle  180  via respective supply lines  185 . The dispensing nozzle  180  preferably may be a multi-flavor dispensing valve capable of mixing a number of fluids at the same time. Examples of dispensing nozzles that may be used herein are shown in commonly owned U.S. patent application Ser. No. 10/233,867 (U.S. Patent Publication No. US 2004/0040983 A1), entitled “Dispensing Nozzle” and commonly-owned U.S. patent application Ser. No. 11/276,551, entitled “Dispensing Nozzle Assembly”. Collectively or individually, the supply lines  175 ,  185  can be known as beverage supply lines. 
     The sensors  165  can be operable to detect a no or low flow condition in the respective supply lines  175 ,  185 , and can communicate a corresponding signal to the control device  120  when a no or low flow condition is detected. The control device  120  can generate an indication that a no or low flow condition exists with the respective supply lines  175 ,  185 . For example, upon receipt of an indication from a control device  120  that a no or low flow condition exists in a particular supply line such as  175  or  185 , the control device  120  can output a signal to a user, for instance via a user interface such as  304  in  FIG. 3 , that a certain product or ingredient has a no or low flow condition in the associated supply line. This signal may be an indicator that the certain product or ingredient has been exhausted or is in a “sold out” condition. The sensors  165  in  FIG. 1  are shown positioned with respect to a supply line, such as  175 ,  185 , for each ingredient source  140 ,  150 . One will recognize that the sensors  165  can be positioned in any location with respect to a supply line  175 ,  185  between at least one ingredient source  140 ,  150  and a dispenser nozzle, such as  180 . 
     In certain embodiments, when a “sold out” condition occurs for a particular product or ingredient, the missing ingredient can affect beverage taste and/or beverage quality, and therefore, the associated product dispenser, such as  100 , may altogether stop or otherwise cease attempting to dispense the particular product or ingredient. A control device, such as  120 , can provide a user or operator with an opportunity to reset the sensor  165  upon correction of the “sold out” condition for the one or more particular products or ingredients. In this manner, a prime or priming operation can be performed for the “sold out” product or ingredient which “resets” the associated sensor  165 , and permits the product dispenser, such as  100 , to again permit dispensing of the particular product or ingredient. 
     Generally shown in  FIG. 1 , the dispensing nozzle can include a flow director  190  with a number of conduits extending therethrough. In this example, the flow director  190  may have a first conduit  200  and a second conduit  210  extending therethrough. The first conduit  200  may be used for water, other types of diluents, or other fluids. The second conduit  210  may be used for a macro-ingredient such as sweetened concentrate, sugar syrup, HFCS syrup, juice concentrate, or other type of fluids. Positioned beneath the flow director  190  may be a target, which may include a number of vertically extending fins that form a number of U- or V-shaped channels. The water, the macro-ingredients, or other fluids may flow out of the flow director  190  and down along the channels of the target so as to begin mixing. 
     Positioned adjacent to the flow director  190  may be a tertiary flow assembly  250 . The tertiary flow assembly  250  may include a number of modules, which may have a number of conduits  270  extending therethrough. The conduits  270  may have differing sizes and configurations depending upon the nature of the intended flow therethrough. The modules may be replaceable and interchangeable. Each of the modules and the conduits  270  may be in communication with one of the micro-ingredient sources  150  or other types of fluids. The conduits  270  may be aimed towards the target so as to mix the micro-ingredients or other fluid with the water, the macro-ingredients, or other fluid. Any number of micro-ingredients or other types of fluids may be used at the same time. 
     As stated above, the control device  120  may be, for example, a processor or controller. The control device  120  may include one or more computer-executable instructions  280  stored in an associated memory, such as  290 , or other computer-readable medium. The computer-executable instructions can include instructions operable to receive a command to prime the product dispenser, and to activate the at least one pump, wherein a predefined amount of the respective beverage ingredients is simultaneously introduced into each of the plurality of beverage supply lines. 
     In at least one embodiment, wherein a product dispenser includes a respective pump for each of a plurality of beverage ingredient sources, a control device  120 , such as a controller, may be in communication with each of the respective pumps. In this embodiment, the control device  120 , such as a controller, can further include computer-executable instructions operable to activate each of the respective pumps, wherein a predefined amount of the respective beverage ingredients is simultaneously introduced into each of the plurality of beverage supply lines. In one example, a predefined amount can be an amount sufficient to clear each of the plurality of beverage supply lines of any air pocket between the respective beverage ingredient source and a respective sensor associated with each of the plurality of beverage supply lines. In another example, a predefined amount can be an amount sufficient to clear each of the plurality of beverage supply lines of any air pocket between the respective beverage ingredient source and the dispensing nozzle. 
     In at least one embodiment, a control device  120 , such as a controller, can further include computer-executable instructions operable to receive a selection of more than one of a plurality of beverage supply lines to prime. In this embodiment, the control device  120 , such as a controller, can activate each of the respective pumps for the selected beverage supply lines, wherein a predefined amount of the respective beverage ingredients is simultaneously introduced into each of the selected beverage supply lines. In certain embodiments, the control device  120 , such as a controller, can activate each of the respective pumps for all of the beverage supply lines, wherein a predefined amount of the respective beverage ingredients is simultaneously introduced into each of the selected beverage supply lines. In one example, a predefined amount can be an amount sufficient to clear each of the selected beverage supply lines of any air pocket between the respective beverage ingredient source and a respective sensor associated with each of the selected beverage supply lines. In another example, a predefined amount can be an amount sufficient to clear each of the selected beverage supply lines of any air pocket between the respective beverage ingredient source and the dispensing nozzle. 
       FIG. 2  shows an embodiment of the user interface  110 , an interface  300 . As shown, the user interface can be a graphical interface, which may include one or more physical buttons and/or computer generated touch screen display buttons or icons. In any instance, the interface  300  may include one or more predefined product prime buttons  302 . Each product prime button  302  may represent a different base product, product component, or ingredient source. When desired, each product prime button  302  can be selected by a user to prime an associated beverage supply line, such as  175 ,  185 , for the particular base product, product component, or ingredient source. Each product prime button  302  may have an indicator  304  that may signal to a user that a certain product or ingredient has been exhausted or is in a “sold out” condition. In this manner, a user can readily observe which base product, product component, or ingredient source may require replacement prior to performing a priming operation after installation of or replacement with a new base product or product component container. 
     The interface  300  may also include an all prime button  306 , which may be used to simultaneously prime all of the associated beverage supply lines, such as  175 ,  185 , for all of the base products, product components, or ingredient sources associated with the product dispenser. In one embodiment, the all prime button  306  can initiate a one button prime command which simultaneously primes all beverage supply lines  175 ,  185  in the product dispenser. Generally, when the all prime button  306  is used, a product dispenser operator can simultaneously prime multiple beverage supply lines for multiple different base products or product components immediately after installation of or replacement with one or more new base product or product component containers. 
     The interface  300  may also include an all purge button or Hyperstart™ button  308 , which may be used to simultaneously purge some or all of the associated beverage supply lines, such as  175 ,  185 , for all of the base products, product components, or ingredient sources associated with the product dispenser. In one embodiment, the all purge button or Hyperstart™ button  308  can initiate a one button purge command which simultaneously purges all beverage supply lines  175 ,  185  in the product dispenser. Generally, when the all purge button or Hyperstart™ button  308  is used, a product dispenser operator can simultaneously purge multiple beverage supply lines for multiple different base products or product components immediately after installation of all new base product or product component containers, which is typically done at a new installation of the product dispenser or at a product dispenser manufacturing facility when the entire product dispenser is flushed for cleaning or testing purposes. 
     Furthermore, the interface  300  may include one or more selectable group prime buttons  310 . Each product group button  310  may represent a different group of base products, product components, or ingredient sources. When desired, each product group prime button  310  can be selected by a user to prime associated beverage supply lines, such as  175 ,  185 , for a particular group of base products, product components, or ingredient sources. When the product group prime button  310  is used, a product dispenser operator can simultaneously prime multiple beverage supply lines for a single group of different base products or product components immediately after installation of one or more new base product or product component containers. While the group prime buttons  310  shown in  FIG. 2  indicate successive groups of products, such as A-C, D-F, G-J, and X-Z, any number of products can be grouped together or otherwise can be grouped together regardless of any predefined product dispenser order, such as A-Z, in accordance with embodiments of invention. For example, each of the group prime buttons can be independently programmed to group certain selected products together, such as related products, components, or ingredients. One will recognize the applicability of group priming to group purging, and one or more group purging buttons can be provided in other embodiments of a product dispenser. 
     The interface  300  may provide a user, such as an individual product dispenser operator, with secure access by password, smart card, biometric identification, credit card, RFID, or otherwise. In certain embodiments, the user interface  300  may provide a user with certain product prime buttons corresponding to those base products, product components, or ingredient sources which need or require a priming operation and/or an all prime button which can prime only those base products or product components which need or require a priming operation, and other types of information. In other embodiments, the user interface  300  may provide a user with certain product purge buttons corresponding to those base products, product components, or ingredient sources which need or require a purging operation and/or an all purge button which can purge only those base products, product components, or ingredient sources which need or require a purging operation, and other types of information. In further embodiments, the user interface  300  may restrict and/or allow which and how much of various ingredient sources, base products, or product components may be primed or purged by a user, such as product dispenser operator. User or operator preferences also may be retained and used for future product dispenser maintenance. 
     In addition to the graphical interface, the product dispenser  100  as a whole may provide other product dispenser statistics and troubleshooting information. For example, the delay time for the start of the pumps  160  or the metering devices  170 , the times for the vent and/or flush cycles, the portion cycles, etc. may be accessed through the user interface  110 ,  300 . This interface  110 ,  300  may be password or otherwise protected. The user interface  110 ,  300  may communicate and/or be accessed as needed with a network or other source for troubleshooting or repair and for notifications or alerts, for example, of a potential incorrect dose of ingredients. 
     In use, a user such as a product dispenser operator, for example a food service employee and/or dispenser technician, may select a desired beverage to prime from the user interface  110 . The product dispenser  100  thus provides a user with the ability to simultaneously prime or purge associated beverage supply lines for any number of or all of the beverages offered by the product dispenser  100  as desired. The user can select some or all of the ingredients as needed to perform a simultaneous priming or purging operation on the associated beverage supply lines. As such, the user can simultaneously prime or purge all of the beverage supply lines for a product dispenser with a single operation. 
     In one embodiment, a user can request priming or purging of the beverage supply lines of any number of particular “branded” beverages that may be sold out or for which the associated containers have recently been replaced. For example, icons associated with the “Cherry Coke®” beverage and the “Coca-Cola®” beverage sold by The Coca-Cola Company of Atlanta, Ga. can be displayed on a user interface, such as  300  in  FIG. 2 , when the product dispenser detects that a priming or purging operation can be performed for the particular beverage and associated beverage supply lines. If desired, the user can prime each beverage supply line by selecting the respective icons, or may decide to select an all prime button, similar to  306 , to simultaneously prime all or a selected number of associated beverage supply lines. Furthermore, if desired, the user can purge each beverage supply line by selecting the respective icons, or may decide to select an all purge button, similar to  308 , to simultaneously purge all or a selected number of associated beverage supply lines. The product dispenser  100  thus may provide via the user interface  300  as many “branded” beverages as may be available from the product dispenser  100  and/or as may need or otherwise require a priming or purging operation. 
     The interface  110 , with the control device  120 , can instruct some or all of the individual pumps  160  and/or the metering devices  170  to dispense suitable ingredients in the appropriate proportions through the beverage supply lines  175 ,  185  towards the dispensing nozzle  180 . The pumps  160  and the metering devices  170  may be pulsed on and off as desired to vary the flow rate, or may otherwise be activated for a predetermined amount of time to introduce a predefined amount of each respective ingredient into the respective beverage supply lines  175 ,  185 . For example, all of the pumps  160  and the metering devices  170  may be activated for about 5 seconds to introduce a predefined amount, such as 5 ml, of each respective ingredient into the respective beverage supply lines  175 ,  185 . In another example, all of the pumps  160  and the metering devices  170  may be activated as needed to introduce a predefined amount of each respective ingredient into the respective beverage supply lines  175 ,  185  to reset a respective sensor associated with each beverage supply line. In yet another example, all of the pumps  160  and the metering devices  170  may be activated for about 60 seconds to introduce a predefined amount, such as 60 ml, of each respective ingredient into the respective beverage supply lines  175 ,  185  to purge each beverage supply line. Depending on the type of ingredients and/or beverages, different flow rates and flow timing may be employed, e.g., certain fluid streams may be added early or late, certain fluid streams may be pulsed, etc. 
     The use of a single button prime operation with the individual pumps  160  and/or the metering devices  170  for the water source  130 , the macro-ingredient sources  140 , and the macro-ingredient sources  150  provides the ability to simultaneously prime some or all of the ingredients offered by the product dispenser  100 . In other words, as opposed to a conventional prime operation where each beverage and/or ingredient had to be primed in successive operations, the product dispenser  100  shown in  FIG. 1  can provide for simultaneous priming of some or all of the beverages and/or ingredients as well as their respective beverage supply lines. Likewise, the use of a single button purge operation with the individual pumps  160  and/or the metering devices  170  for the water source  130 , the macro-ingredient sources  140 , and the macro-ingredient sources  150  provides the ability to simultaneously purge some or all of the ingredients offered by the product dispenser  100 . In other words, as opposed to a conventional purge operation where each beverage and/or ingredient had to be purged in successive operations, the product dispenser  100  shown in  FIG. 1  can provide for simultaneous purging of some or all of the beverages and/or ingredients as well as their respective beverage supply lines. Embodiments of the invention thus have applicability to conventional countertop devices, vending devices, and various types of bottling and filling devices. Although embodiments of the invention are described in terms of the product dispenser  100 , embodiments of the invention are applicable to the combination of any types of ingredients, wet or dry. For example, commonly owned U.S. patent application Ser. No. 11/276,549, entitled “Juice Dispensing System”, is specifically directed towards certain concepts related to the juice field.
