Patent Application
20230312324
The present application provides a novel and useful apparatus for nitrogenizing a beverage such as tea or coffee.
“Cold brew coffee” has become a popular beverage and is prepared by steeping coffee grounds in cold water. Nitrogen has often been added to these beverages and other beverages, such as beer, tea, juices, milk, and the like. Such beverages may be nitrogenized with the apparatus of the present application.
Cold brew coffee is often packaged as a ready-to-drink item. As such, cold brew coffee is either packaged in a can or bottle or dispensed via a tap at a place of purchase.
Nitrogenized cold brew coffee may also be prepared and served or dispensed. To prepare nitrogenized cold brew coffee, unsweetened black coffee is infused or combined with nitrogen gas. Such a beverage is often referred to as “nitro cold brew” or “nitro coffee”. The introduction of nitrogen to cold brew coffee changes the appearance of the coffee from a heavy, dark, black liquor to a lighter colored, frothy, and creamy beverage. Consumers find nitro coffee to be visually and texturally appealing and desirable. Such a popularity is due to the taste of the nitro coffee since it is creamier and sweeter than the typical uninfused cold brew coffee.
In the past, nitrogenizing of cold brew coffee and other beverages have generally been limited to infusing the nitrogen before its distribution. For example, the prior dispensing of cold brew coffee places the beverage in a holding still followed by infusion with nitrogen. The beverage is then dispensed with a specific type of tap faucet referred to as a “stout faucet”. In other words, the prior methods for nitrogenization of cold brew coffee requires a special type of faucet for distribution.
Various prior art systems have been proposed to combine gaseous material with a liquid. For example, United States Patent Publication 2018/0318777 describes a liquid drink dispensing apparatus in which a gas generating component and a liquid drink dispensing element form an apparatus. The gas generated infuses a liquid drink prior to dispensing.
United States Patent Publication 2018/02113824 shows a technique and method for injecting a gas into a beverage. The beverage is placed into a container and a gas is pumped into the delivery device having a porous end portion to deliver the gas to the liquid.
U.S. Pat. No. 9,801,405 shows a method to prepare and dispense gaseous-infused beverages in which a beverage concentrate is utilized and mixed with a particular gas such as nitrogen or carbon dioxide. A slow pour faucet is then employed to deliver the infused liquid for use.
European patent specification EP2783743 shows a method for processing a fluid in which a gas is sparged into a fluid to form a humid gas. The humid gas is passed from the container into a condenser bag for cooling, which causes separation of the components into a condensed fluid in a dehumidified gas. The condensed fluid is then combined with components or recirculated back to the still.
Korean Publication KR1020160099794A teaches an apparatus to produce lotions, drops, gels, ointments, and the like by placing a fluid in a container with an impeller. Dissolved gasses are then added to infuse liquids in the container and produce a fluid with a large amount of nanobubbles.
International Publication WO2018/148843 illustrates the combination of a liquid by infusion of carbon dioxide into such liquid by mixing the same with a magnetic mixer.
International Publication WO2018/156361 involves a method of mixing a first beverage with a second beverage through the use of an external control system.
An apparatus for the infusion of nitrogen into a beverage and the production of near microscopic bubbles to produce a drink which exhibits superior flavor and visual appeal would be a notable step in the beverage processing industry.
In accordance with the present application, a novel and useful apparatus for nitrogenizing a beverage by infusion of gaseous nitrogen from a source is herein provided.
The apparatus of the present application utilizes a container having a chamber for the beverage and is formed by a base and a side portion that extends from the base. The container is formed by a base a side portion extending therefrom. At least one baffle is located in the chamber and is positioned along the side portion of the container. The apparatus is also constructed with a lid from which at least one baffle, and preferably a multiplicity of baffles, depend. Thus, a multiplicity of baffles extend into the chamber of the container from the lid. Once in the container, the multiplicity of baffles are positioned along the inside wall portion of the side portion of the container.
A port, having an orifice, is located in the base of the container to control or regulate the passage of gaseous nitrogen from a source to a beverage in the chamber of the container. The port may be formed of a resilient element that is located at the base of the container. The flow of nitrogen gas from the source to the chamber of the container, via a support, causes enlargement of the orifice. Such enlargement is a result of the pressure of the nitrogen gas at the port orifice and serves to regulate the flow of nitrogen gas into the chamber into the container. Interruption of nitrogen gas to the port orifice closes the orifice and prevents the flow of nitrogen gas to the container chamber.
An agitator is also employed in the present apparatus. The agitator may take the form of a shaft which extends into the chamber of the container to create a shearing force on the beverage within the chamber of the container. The agitator is preferably positioned adjacent the port orifice, from which the nitrogen gas is emanating, and adjacent to the at least one baffle. A motor is employed to turn the shaft of the agitator and is mounted on a plate located apart from the container. The apparatus further includes a housing, which may be employed to aid in the positioning of the motor for turning the shaft. In certain instances, the motor mounted to the plate is located in the housing. Plate further includes a conical protrusion having an opening through the same. The lid of the container may be also provided with a concave fitting having an aperture to allow the shaft to extend into the chamber of the container. Thus, the plate protrusion opening aligns with the aperture through the concave fitting on the lid such that the shaft extends through the aperture of the concave fitting of the plate, the aperture of concave fitting, and into the chamber of the container.
A first conventional controller regulates the activity of the motor and the agitator while a second controller regulates rate of entry of the gaseous nitrogen through the port orifice at the base of the container. As heretofore stated, the orifice of the resilient port at the base of the container provides such regulation through the quantity of pressure of gaseous nitrogen fed to the resilient port.
A support for the container is also included in the present apparatus and is formed with a nitrogen delivery system that communicates with the resilient port located at the base of the container. Specifically, the support is rotatably attached to the housing and includes a passageway therethrough, which conducts gaseous nitrogen to the port at the base of the container.
It may be apparent that a novel and useful apparatus for infusing gaseous nitrogen from a source to a beverage has hereinabove described.
It is therefore an object of the present application to provide an apparatus for infusing gaseous nitrogen from a source into a beverage that combines the steps of infusion and dispersion of nitrogen gas into a beverage.
