Definitions

  • the present invention relates to a nozzle for dispensing carbonated or pressurized beverages, and more specifically to a removable nozzle for adapting a conventional carbonated beverage faucet to dispense carbonated or pressurized beverages at high flow rates with minimal foaming.
  • Pressurized beverages such as beer
  • the beverage contains a certain amount of dissolved gas, typically carbon dioxide (C0 2 ). While a certain amount of dissolved C0 2 occurs naturally in the beer brewing and fermentation process, most large commercial breweries dissolve additional CO2 into their product. Adding additional C0 2 serves two main purposes for the commercial breweries. First, from a quality control standpoint, all the beer produced can be modified to contain the same amount of C0 2 . Second, the additional C0 2 gives the beer a more effervescent quality, which is perceived by the consumer as having better crispness and flavor.
  • C0 2 carbon dioxide
  • Beer produced by most major breweries contains between 10 and 15 psi (68950 and 103425 Newtons per square meter) of dissolved C0 2 . Since atmospheric levels of C0 2 are substantially smaller, beer has a tendency to release some of its dissolved C0 2 when exposed to the ambient atmosphere. Due to the complex chemical makeup of beer, foam tends to form when this dissolved C0 2 comes out of solution. [0005] Additional parameters contributing to the amount of foam occurring in beer include temperature and turbulence. The physical properties of liquids dictate that the higher the liquid temperature, the lower its capacity for dissolved gasses. Thus, the greater the temperature of beer, the greater the tendency for its dissolved gasses to come out of solution and the greater the tendency of the beer to foam. Turbulence and other forms of agitation produce regions of sudden, extreme pressure variation within the beer that cause C0 2 to come out of solution in the form of foam.
  • Kegs are reusable and refillable aluminum containers that allow for efficient, sanitary handling, storage and dispensing of typically 15.5 gallons (58.7 liters) of beer. Beer packaged into kegs, called keg beer, is commonly served at bars, taverns, night clubs, stadiums, festivals and large parties.
  • Dispensing keg beer into open containers for consumption requires specialized equipment.
  • the beer dispensing faucet (commonly called the beer tap) comprises a valve and a spout for controlling and directing the flow of beer into an open container.
  • Beer often foams as it is dispensed from conventional faucets.
  • One cause of such foaming is simply the pressure differential between C0 2 dissolved in the beer and C0 2 present in the ambient atmosphere; C0 2 will naturally be released from the beer when the beer is exposed to the atmosphere.
  • Another cause of such foaming is the turbulent nature by which beer is dispensed from conventional faucets; even when dispensed carefully, beer splashes onto the walls and bottom of the container and foam results. [0008]
  • a small amount of foam is often desirable. Beer that has not been stored properly often loses its dissolved C0 2 to the atmosphere and is considered to be flat. Thus, a small amount of foam indicates to the consumer that the beer is fresh.
  • the present invention is directed to a beverage dispensing device for dispensing pressurized beverages at a flow rate substantially higher than prior mechanical tap apparatus without producing excessive foaming. It can be implemented as a purely mechanical device so as to keep manufacturing and maintenance costs low. In addition, the present invention can be implemented without the use of reservoirs at or near the point of dispensing, thus facilitating cleaning and retrofitting to existing bar tops.
  • the present invention comprises a beverage dispensing apparatus for dispensing a pressurized beverage comprising a nozzle through which the pressurized beverage at least initially exits at atmospheric conditions having an internal passageway, a liquid receiving end adapted to attach as the end element of a pressurized beverage dispensing system, and a liquid dispensing end that dispenses the pressurized beverage at least initially to atmospheric conditions, wherein the cross-sectional area of the internal passageway of the nozzle decreases from the liquid receiving end to the liquid dispensing end.
  • the nozzle is adapted at its liquid receiving end to removably and sealingly fit to the end of a conventional carbonated beverage faucet.
  • the present invention comprises an upward extending neck, a streamlined valve assembly and a downward extending nozzle assembly.
  • the overall shape and size of the device permits a range of containers to be filled from the bottom.
  • the nozzle assembly contains a streamlined flow redirecting component that serves to generally radially disperse liquid flow.
  • the amount of foaming that occurs when beer is dispensed at fast rates is desirably reduced.
  • the horizontal cross-sectional area of the nozzle gradually decreases from the top of the nozzle to the bottom or liquid dispensing end of the nozzle.
  • the profile of this decreasing cross-sectional area is consistent with that of a liquid stream falling under the force of gravity in the absence of such a nozzle.
  • a nozzle with this shape ensures that liquid flowing through it remains in substantially continuous contact with the interior wall of the nozzle. In this way, air from the liquid dispensing end of the nozzle is prevented from bubbling up into the nozzle.
  • the viscous forces acting between the nozzle interior wall and the liquid flowing through the nozzle serve to counteract the acceleration experienced by the liquid in the nozzle due to gravitational forces.
  • flow-straightening elements are added to the nozzle which may serve to make the flow of liquid through the nozzle less turbulent. Such elements also increase the amount of surface area across which decelerating viscous forces can take
  • the device is able to selectively dispense beer at two different flow rates.
  • a pressure-reducing element is integrated into the device along with a multi-way valve that selectively routes liquid through the pressure-reducing element.
  • the valve When the valve is positioned such that liquid first flows through the pressure reducer before entering the rapid beverage dispensing device, liquid is dispensed at a reduced rate, preferably the optimal rate of conventional beer dispensing faucets.
  • the valve When the valve is positioned such that liquid bypasses the pressure reducer, the rapid beverage dispensing device functions at its faster flow rate.
  • the rapid beverage dispensing device is capable of dispensing beer at at least twice the flow rate of conventional beer dispensing systems while still achieving optimal levels of foam, it also tends to attract attention from beverage consumers as an object of curiosity. This attraction can be heightened by forming components of the device from transparent material to allow consumers to see the beverage flowing therein.

  • neck assembly 36 is substantially vertical.
  • the rapid beverage dispensing device 35 is designed to attach to a conventional pressurized beverage dispensing system, such as a beer dispensing system 39 that includes a beer keg 40 or similar beverage-containing reservoir and beverage tubing 41 for conveying a beverage from a container or beer keg 40 to the rapid beverage dispensing device 35.

  • Beer produced by most major manufacturers in the United States is formulated to be stored and served optimally at approximately 38 degrees Fahrenheit (3.3 degrees Celsius). If the beer is warmer than this optimal temperature, it will tend to release too much carbon dioxide (C0 2 ) when it is dispensed. If the beer is colder than this optimal temperature, it will tend to retain too much C0 2 when it is dispensed and have a muled flavor. Since most systems are not able to maintain a precise temperature, a range between 36 and 40 degrees Fahrenheit (2.2 and 4.4 degrees Celsius) is generally considered acceptable. Accordingly, in one embodiment, the beer dispensing system 39 of the present invention has the ability to cool various elements of the system and maintain these elements within this acceptable temperature range. [0050] As shown in FIG.

  • some systems blow cold air through conduits containing the beverage tubing 41 as a means of keeping the beverage tubing 41 cold.
  • Beer contained in a beer keg 40 requires an energy source for conveying the beverage from the beer keg 40 through the entire beer dispensing system 39 to the rapid beverage dispensing device 35.
  • energy is commonly provided via pressurized gas, typically pressurized C0 2 .

  • the Reynolds number is a dimensionless parameter often used in fluid flow analysis. Fluid moving through round piping or tubing possessing a Reynolds number under 2100 is said to exhibit laminar flow.
