This invention is in the field of infusing and flavoring liquids for human consumption. The invention relates to a Liquid Infusing, Flavoring, and Dispensing Device. The invention is useful for infusing, flavoring and dispensing alcoholic liquids. The invention is particularly useful for infusing, flavoring and dispensing beer into a drinking vessel.
The practice of infusing and flavoring liquids for human consumption has been used for centuries. Making tea is a good example. It is becoming more common to infuse alcoholic beverages with different flavoring substances. Specialty flavored beers are becoming especially popular. Traditionally, flavor, such as from hops, is infused into the beer during the brewing process. However, many of the delicate aroma and flavor of flavoring substances do not survive the brewing process. The hops that are commonly used to flavor beer are composed of two main parts, Alpha and Beta acids. The Beta acids, which are responsible for most of the aromatic qualities of the beer, are very delicate and do not survive the brewing process. Thus, much of the desired qualities are lost during the brewing process. One solution to the problem of loss of flavor and aroma during the brewing process is to infuse the beer after brewing, and preferable just prior to or during dispensing into a drinking vessel. However, currently available infusing systems subject the beer to trauma during the infusing process, yielding beer that is flat, warm and usually very slow to pour. Moreover, up to 45% of a keg of beer can be lost due to foaming in currently available systems. One such system is described in U.S. Pat. No. 8,245,629.
The present invention is directed to a Modular Liquid Infusing, Flavoring and Dispensing Device (the “Device of the Invention”) that provides a means to infuse flavor into liquids for variable periods of time prior to dispensing, and after the brewing process, wherein the system provides a means to control the rate at which the liquid is dispensed, reduces the trauma to the dispensed liquid, and reduces the amount of foaming in the dispensed liquid.

The present invention is directed to a Modular Liquid Infusing, Flavoring and Dispensing Device that provides a means to infuse flavor into liquids for variable periods of time prior to dispensing, and after the brewing process, wherein the system provides a means to control the rate at which the liquid is dispensed, reduces the trauma to the dispensed liquid, and reduces the amount of foaming in the dispensed liquid.
The invention includes a process and a device for infusing aroma and flavor into a liquid, preferably beer, by allowing the liquid from a tapped source to contact a flavor enhancing solid material for a variable period of time prior to entering a drinking container such as a beer glass. This is accomplished by using the device of the invention that contains the solid flavor-enhancing material in such a fashion that the solid material contacts the liquid after the liquid leaves the tap, but before dispensing the liquid, in such a manner that the flavor-enhancing solid material does not flow into the drinking container. The device has an infusion chamber and optionally one or more additional in-line chambers, wherein the infusion chamber contains a flavor-enhancing solid material, and wherein each chamber is bounded on either end of the flow system with a shut-off valve/clamp allowing simple replacement, re-filling, or cleaning of the chamber without disconnecting the overall system from the tapped source. The infusion chamber can optionally be vacuum-jacketed which allows continuous circulation of a cooling solution such as glycol or ice water around the dispensing outlet to regulate the final temperature of the liquid dispensed into the drinking container. This chamber may optionally be filled with solid cooling materials as well, including dry ice or standard ice from water. The overall system is designed to produce a flavored beer or other beverage with minimal foaming and at the optimal drinking temperature to enhance the aroma and drinking experience.

In one embodiment the liquid is an alcoholic beverage.
In another embodiment, the liquid is beer.
In one embodiment, the Devise of the Invention comprises:
The present invention is directed to a process for using the modular liquid infusing, flavoring and dispensing device to flavor a liquid wherein the liquid from a tapped source is in liquid communication with the first hose member, the inlet passage of the first holding means, the outlet passage of the first holding means, the inlet passage of the second holding means, the third hose member, and the tap member.
In one embodiment of the process of the invention, the pressure relief valve is opened, causing the modular liquid infusing, flavoring and dispensing device to fill with more liquid volume.
In one embodiment, the liquid that is infused, flavored and dispensed is an alcoholic beverage.
In another embodiment, the liquid is beer.
In a non-limiting embodiment, the device of the invention is configured as follows, a first hose member is connected to the tap source. In reference to the appended Figures, a first hose member runs up through the pipe tower housing 1, 2, and connects to the hose barb of the first hose barb junction 3). Liquid from the tapped source flows through the first hose member to fill the first holding means 5. A filter gasket 11, 12 is situated at the top of the first holding means between the first hose barb junction and the first holding means helps to prevent foaming of the liquid. This filter gasket, located at the highest connection-clamp position on the device, serves to prevent foam from passing through while allowing air to exit, thereby reducing foaming out of the pressure relief valve 4 located at the top of the first holding means. The pressure relief valve controls the rate at which gas leaves the system, and controls the rate at which liquid enters the system. The pressure relief valve gives the user/operator more control over the fill rate, thus further aiding the control over foaming of the liquid.
The liquid flows into the second holding means through the outlet passage of the first holding means (5) and through the inlet passage of the second holding means (7). There is a gasket at the top of the second holding means between the outlet passage of the first holding means and the inlet passage of the second holding means. The gasket mesh size ranges from about 4 mesh to about 20 mesh, and is preferably about 10 mesh. The gasket is preferably sock-shaped, extending about 4 inches to about 6 inches into the infusion chamber. When a flat gasket is used at the top of the second holding means/infusion chamber, foam tends to stack on the flat gasket when liquid passes through. Using a sock-shaped gasket increases the surface area of the gasket, thus reducing compaction of the flavoring substance, and reducing the foaming of the liquid in the device.
The second holding means/infusion chamber contains the flavoring substance. A better infusing effect results from the passing friction motion of the liquid traveling at faster speeds through the flavoring substance. To maximize that effect, the system is built long and narrow to encourage the liquid to travel quickly through the infusion chamber. To achieve this effect, the internal diameter of the infusion chamber is from about 1″ to about 6″. Preferably, the internal diameter of the infusion chamber is no greater than about 3″.
There is a filter gasket at the bottom of the infusion chamber. At the bottom of the infusion chamber, below the gasket, there is a “hose terminus.” The hose terminus is a second hose barb junction. The hose terminus provides a recessed space below the lower filter gasket at the bottom of the infusion chamber. The hose terminus provides a recessed space beneath the lower filter gasket. The space beneath the lower filter gasket fills with liquid, and improves flow rate because the liquid in the recessed space covalently “pulls” the liquid in the infusion chamber across the filter gasket. There is a hose barb at the outlet passage of the hose terminus to which the second hose member (#) is attached. The second hose member is attached at the other end to the faucet. The second hose member ranges from about 4″ to about 40″ long. Shorter lengths increase the flow rate, whereas longer lengths decrease the flow rate of the liquid.
The modular liquid infusing, flavoring and dispensing device of the present invention has zero dead volume, and therefore can recover all of the liquid infused from the tapped source. This happens because the liquid enters the system at the highest point and exits at the lowest point, allowing the device to be completely drained of all of the liquid being infused.
Turning the shut off valve (6) to the “OFF” (flow stop) position allows the complete draining of the liquid in the infusion chamber, so that the infusion chamber can be refilled, removed, or replaced without the need to disconnect the system from the tapped source.
The device of the present invention can be variously configured based on its modular construction. With reference to
