The present invention disclosure relates to a wine dispensing system for providing wine by the glass.
Restaurants, taverns and other eating establishments typically supplement their menus with various wines. Such offerings not only enhance the appeal of such restaurants, taverns and eating establishments but they can also significantly increase revenue. For various reasons, however, some diners and tavern patrons do not desire to purchase an entire bottle of wine with their meal. Instead, some diners and tavern patrons prefer to supplement their meal with only one or two glasses of wine.
Although the wine being served may be stored at above or below a desired temperature, some wines taste best if served at a specific temperature. That is, some wines may be stored at an ambient temperature but are typically chilled when they are served to patrons. On the other hand, other wines may stored in a refrigerator or the like but taste best when served within a specific temperature range. A sub-cooled wine typically has a longer life expectancy than wine stored at room or an ambient temperature. When wine is stored in kegs at sub-cooled temperatures, however, crystallization may form in the wine. As such, an added filter may be required
The ability to serve a glass or glasses of wine to a customer and at a predetermined temperature to optimize its flavor and taste, however, has proven problematical for many reasons for restaurants, taverns and other eating establishments. Known wine delivery systems offer unsatisfying compromises between pressure loss, flows, beverage working volumes, temperature controls and system sizes. Compromises regarding any one or more of these aspects can result in a less than satisfying performance.
Known wine delivery systems use a single-pass beverage heat exchanger which uses relatively high volumes of beverage in the heat exchanger resulting in high “end” product waste. Alternatively, low volume wine delivery systems have poor temperature controls over the wine being delivered.
Most known wine delivery systems use high pressure carbon-dioxide or mixed gases to drive or otherwise move the wine through the system. As will be appreciated, high pressure losses in these systems results in low flow rates. Moreover, the high pressure carbon dioxide frequently results in carbonization of the wine—a result not appreciated or desired by the customer. Additionally, such known systems can be expensive to install and operate. Moreover, temperature gradients can occur as the wine moves through the line to the tap or point of disbursement.
As such, some establishments use a counter-top (stand alone compressor, evaporator and condenser) system at a serving station. Such known systems are not only bulky by design but they also consume valuable counter space in an already crowded environment.
Alternatively, and in an effort to overcome the bulky space requirements associated with a counter-top system, some establishments have been known to use an under-the-counter bulky keg refrigeration system at the serving station. These known under-the-counter keg refrigeration systems also take precious space at the serving station. Moreover, these known under-the-counter keg refrigeration systems require timely changing of the kegs when they are emptied. This can be a labor intensive effort which can occur at inopportune occasions.
Thus, there continues to be a need and a desire for a wine dispensing system which addresses and solvers the heretofore known problems and challenges associated with known wine delivery systems.
In view of the above, and in accordance with one aspect, there is provided a system for dispensing wine at a preselected temperature from a dispensing apparatus having a manifold defining an outlet. According to the first family of embodiments, the wine dispensing system includes a tank for holding and storing an intermediate fluid therein and a multi-tube heat exchanger disposed within the tank. The multi-tube heat exchanger has a Reynolds Number of less than 2500 and a total internal volume of less than ten ounces. The multi-tube heat exchanger has an inlet and an outlet. The system of this invention disclosure further includes an apparatus for constantly monitoring and maintaining the intermediate fluid in the tank at a preselected and substantially constant temperature. The inlet end of the tube of the multi-tube heat exchanger is adapted for releasable connection to a source of wine. The outlet end of the tube of the multi-tube heat exchanger is adapted for releasable connection to a manifold to effect a positive laminar flow between the source of wine and the outlet on the dispensing apparatus.
According to another aspect, there is provided a system for dispensing a plurality of different types of wines at a predetermined temperature from a dispensing apparatus with a manifold having a plurality of independent and separate outlets. In this family of embodiments, the wine dispensing system includes a tank for holding and storing an intermediate fluid therein and a plurality of multi-tube heat exchangers disposed within the tank and through which the wines flow. In this family of embodiment, each multi-tube heat exchanger defines a ratio of about of 0.75 square inches/ounces per minute of wine flowing therethrough. Each multi-tube heat exchanger has a tube with an inlet and an outlet. An apparatus is provided for constantly monitoring and maintaining the intermediate fluid in the tank at a preselected and generally constant temperature. The inlet end of the tube of each multi-tube heat exchanger is adapted for releasable connection to a separate source of wine. The outlet end of the tube of each multi-tube heat exchanger is adapted for releasable connection to the manifold to effect a positive laminar flow between the respective source of wine and one of the outlets on the manifold.
According to yet another aspect of this invention disclosure, there is provided a system for dispensing at least three different types of wines at a preselected temperature from a dispensing apparatus with a manifold having three independent and separate outlets. According to this aspect, the wine dispensing system includes a tank for holding and storing an coolant fluid therein and a series of multi-tube heat exchanger disposed within the tank. In this embodiment, each multi-tube heat exchanger has a Reynolds Number of less than 2500 and a total internal volume of less than ten ounces. Each multi-tube heat exchanger defines a ratio of about 0.75 square inches/ounces per minute of wine flowing therethrough. Each multi-tube heat exchanger has a tube with an inlet and an outlet. An apparatus is provided for constantly monitoring and maintaining the coolant fluid in the tank at a selected and generally constant temperature.
The inlet end of the tube of the first multi-tube heat exchanger is adapted for releasable connection to a first source of wine. The outlet end of the tube of the first multi-tube heat exchanger is adapted for releasable connection to the manifold to effect a positive laminar flow between the first source of wine and a first outlet on the manifold. The inlet end of the tube of the second multi-tube heat exchanger is adapted for releasable connection to a second source of wine. The outlet end of the tube of the second multi-tube heat exchanger is adapted for releasable connection to the manifold to effect a positive laminar flow between the second source of wine and a second outlet on the manifold. The inlet end of the tube of the third multi-tube heat exchanger is adapted for releasable connection to a third source of wine. The outlet end of the third tube of the multi-tube heat exchanger is adapted for releasable connection to the manifold to effect a positive laminar flow between the third source of wine and a third outlet on the manifold.
In each embodiment of the invention disclosure, the intermediate fluid in the tank heats and/or cools the wine to be dispensed from the manifold to a desired temperature so as to optimize the taste of the wine. As such, the source of the wines can be stored at temperature above or below the desired temperature at which the wine is to be dispensed. Accordingly, the present invention disclosure readily and conveniently allows the wine to be stored at room temperature or sub-cooled in a refrigerated storage area.
In each embodiment of the invention disclosure, each multi-tube heat exchanger has relatively small diameter lines arranged in multiple passes relative to each other. The multi-tube heat exchangers advantageously offer a relatively low pressure loss between the inlet and outlet ends of each tube of the heat exchanger. The relatively low pressure loss between the inlet and outlet ends of each tube of the heat exchanger is advantageously accomplished while maintaining satisfactory delivery rates/flow of the wine through the heat exchanger. Each multi-tube heat exchanger of the present invention disclosure offers a relatively high efficiency so as to deliver wine at each of the multiple outlets of the manifold at temperature closely corresponding to the selected temperature of the intermediate fluid in the tank. Moreover, the low internal volume of the of each multi-tube heat exchanger minimizes wasted wine product.
Moreover, the multi-tube heat exchanger preferably uses low pressure gas to positively move the wines through the heat exchanger and to the dispensing apparatus. As such, the likelihood of carbonation of the wine is significantly reduced. Notably, wines typically have a very low carbonation rate, i.e. typically below 10 psi.
Preferably, the apparatus for constantly monitoring and maintaining the intermediate fluid in the tank in each embodiment of the wine dispensing system includes either and/or both an intermittently driven pump and a selectively operated valve operably connected to a system for influencing the intermediate fluid temperature in the tank. In a preferred embodiment, the apparatus for constantly monitoring and maintaining the intermediate fluid in the tank in each embodiment of the wine dispensing system includes a closed-loop controller for maintaining the intermediate fluid in the tank at a preselected and substantially constant temperature. To accomplish there desirous results, the apparatus for constantly monitoring and maintaining the coolant fluid in the tank in each embodiment includes a heater for influencing the temperature of the fluid in the tank.
In a preferred form of this invention disclosure, the wine dispensing system is designed and constructed such that fluid from the tank flows in surrounding relation relative to a portion of each tube extending from the multi-tube heat exchanger to the manifold to further maintain a predetermined temperature for the wine.
