The present invention relates to nitrogen gas infused cold brew beverages, such as coffee, and, more particularly, but not by way of limitation, to a dispenser for nitrogen gas infused cold brew beverages and a method for dispensing thereof.
Nitrogen gas infused cold brew beverages such as coffee continue to increase in popularity, creating a demand in the food/drink dispensing industry for dispensers suitable to dispense such beverages. One nitrogen gas infused cold brew coffee dispenser includes a cooling cabinet containing therein a tank filled with coffee. The tank connects at an inlet with a source of nitrogen gas that delivers nitrogen gas into the tank for infusion into the coffee within the tank. The tank connects at an outlet with a faucet secured to the cooling cabinet whereby the faucet delivers nitrogen gas infused cold brew coffee from the tank. Although the dispenser delivers nitrogen gas infused cold brew coffee, combining the nitrogen gas with the coffee in the tank results in a less than satisfactory infusion of the nitrogen gas into the coffee. Moreover, the size of the cooling cabinet limits the venues acceptable for use of the dispenser.
Another nitrogen gas infused cold brew coffee dispenser includes a contactor membrane unit coupled at a gas inlet with a source of nitrogen gas and at a liquid inlet with a pump connected with a tank filled with coffee. The contactor membrane unit receives coffee from the tank via the pump and nitrogen gas from the source of nitrogen gas and contacts the nitrogen gas with the coffee in order to infuse the coffee with the nitrogen gas. The contactor membrane unit connects at an outlet with a faucet securable to a counter whereby the faucet delivers nitrogen gas infused cold brew coffee from the contactor membrane unit. Although the dispenser delivers nitrogen gas infused cold brew coffee, the use of a contactor membrane unit to infuse the coffee with nitrogen gas creates a sanitation issue in that cleaning the contactor membrane unit to prevent bacterial growth within the dispenser can be difficult.
Accordingly, a dispenser with small space requirements that delivers a quality nitrogen gas infused cold brew beverage while offering easy and effective cleaning will improve over prior dispensers.
In accordance with the present invention, a dispenser makes nitrogen gas infused water and then combines the nitrogen gas infused water with a product to create a nitrogen gas infused beverage. The dispenser further chills the nitrogen gas infused beverage to produce a nitrogen gas infused cold brew beverage for dispensing therefrom.
The dispenser in a preferred embodiment includes a product container, a nitrogenator, a mixing unit, and a dispensing unit. The nitrogenator receives water from a water source and nitrogen gas from a nitrogen gas source and infuses the nitrogen gas into the water to produce nitrogen gas infused water. The mixing unit receives product from the product container and nitrogen gas infused water from the nitrogenator. The mixing unit combines the product and the nitrogen gas infused water to induce a mixing thereof that creates a nitrogen gas infused beverage. The dispensing unit receives nitrogen gas infused beverage from the mixing unit and chills the nitrogen gas infused beverage to produce a nitrogen gas infused cold brew beverage for dispensing therefrom.

As illustrated by
The mixer 34 includes a product line segment 41 having a product inlet 42 and a nitrogenated water line segment 43 having a nitrogenated water inlet 44. The product line segment 41 and the nitrogenated water line segment 43 merge at a mixing line segment 45 to contact the product with the nitrogenated water resulting in the mixing of the product and the nitrogenated water into a nitrogen gas infused beverage. The mixing line segment 45 terminates in the beverage outlet 30 that extends through the aperture 40. In the preferred embodiment, the mixer 34 comprises a U-shaped tube, which includes first and second inlets, joined with an outlet tube.
The product flow control assembly 32 includes a flow rate controller 46, which may be any suitable flow rate controller such as a flow rate control valve including a spring-loaded ceramic piston well known to one of ordinary skill in the art. The flow rate controller 46 includes an inlet coupled with the product line 27 to receive product therefrom and an outlet coupled with the product inlet 42 of the product line segment 41 for the mixer 34. The flow rate controller 46 in the preferred embodiment is adjustable to either increase or decrease the flow rate of the product through the product flow control assembly 32 and to the mixer 34. An adjustment of the flow rate controller 46 to raise the flow rate of the product increases the amount of product delivered to the mixer 34, thereby enhancing the strength of the resulting nitrogen gas infused beverage. Conversely, an adjustment of the flow rate controller 46 to lower the flow rate of the product decreases the amount of product delivered to the mixer 34, thereby diminishing the strength of the resulting nitrogen gas infused beverage.

The flow rate controller 49 in the preferred embodiment is adjustable to either increase or decrease the flow rate of the nitrogenated water through the nitrogenated water flow control assembly 33 and to the mixer 34. An adjustment of the flow rate controller 49 to raise the flow rate of the nitrogenated water increases the amount of nitrogenated water delivered to the mixer 34, thereby diminishing the strength of the resulting nitrogen gas infused beverage. Conversely, an adjustment of the flow rate controller 49 to lower the flow rate of the nitrogenated water decreases the amount of nitrogenated water delivered to the mixer 34, thereby enhancing the strength of the resulting nitrogen gas infused beverage.
The nitrogenated water flow control assembly 33 in the preferred embodiment further includes a regulator 50, a shut-off valve 51 and a check valve 52.

The check valve 52 permits nitrogenated water flow to the mixer 34 while preventing back-flow of nitrogenated water or product to the flow controller 49. Although the nitrogenated water flow control assembly 33 in the preferred embodiment includes a regulator 50, a shut-off valve 51, and a check valve 52, one of ordinary skill in the art will recognize that the nitrogenated water flow control assembly 33 may comprise only the flow controller 49.
The dispensing unit 11 receives the nitrogen gas infused beverage from the mixing unit 12 via the beverage line 31 and chills the nitrogen gas infused beverage to produce a nitrogen gas infused cold brew beverage prior to the dispensing thereof to a consumer. As illustrated by
Before delivering a nitrogen gas infused cold brew beverage to a consumer, the nitrogen gas infused cold brew beverage delivered from the dispensing unit 11 may be regulated with respect to strength and thus taste and flavor. An operator of the dispenser 10 dispenses a nitrogen gas infused cold brew beverage into a container and, based on the taste/flavor of the beverage in combination with its visual appearance, the operator adjusts the mixing unit 12. In particular, the operator adjusts the flow rate controller 46 of the mixing unit 12 to raise the flow rate of the product and increase the amount of product delivered to the mixer 34, thereby enhancing the strength of the resulting nitrogen gas infused beverage. Similarly, the operator adjusts the flow rate controller 49 of the mixing unit 12 to lower the flow rate of the nitrogenated water and decrease the amount of nitrogenated water delivered to the mixer 34, thereby enhancing the strength of the resulting nitrogen gas infused beverage. Conversely, the operator adjusts the flow rate controller 46 to lower the flow rate of the product and decrease the amount of product delivered to the mixer 34, thereby diminishing the strength of the resulting nitrogen gas infused beverage. Similarly, the operator adjusts the flow rate controller 49 to raise the flow rate of the nitrogenated water and increase the amount of nitrogenated water delivered to the mixer 34, thereby diminishing the strength of the resulting nitrogen gas infused beverage. The operator adjusts the flow rate controllers 46 and 49 of the mixing unit 12 until the resulting nitrogen gas infused beverage provides the desired visual appearance along with the more important desired taste and flavor. The flow rate controllers 46 and 49 deliver the product and the nitrogenated water, respectively, to the mixer 34, which contacts the product with the nitrogenated water resulting in the mixing of the product and the nitrogenated water into the nitrogen gas infused beverage. Although an operator may subjectively adjust the taste and flavor of the nitrogen gas infused beverage, one of ordinary skill in the art will recognize that specific ratios of the product relative to the nitrogenated water may be used.
The dispenser 10 provides an improvement in the dispensing of nitrogen gas infused cold brew beverages by including a mixing unit 12 with a mixer 34 that is fed from a separate nitrogenator 13 and a separate product container 15. The nitrogenator 13 ensures nitrogen gas properly infuses into the water to form the nitrogenated water delivered to the mixer 34, and the mixer 34 ensures the product mixes and substantially, completely combines with the nitrogenated water to create a nitrogen gas infused beverage. Moreover, an advantage of the dispenser 10 is the ease in its cleaning without disassembly. In particular, the pump 14 is disconnected from the product container 15 and connected with a container holding a cleaning solution. Operation of the pump 14 pumps the cleaning solution through the product flow control assembly 32, the product line segment 41, the mixing line segment 45, and the dispensing unit 11 including an opened faucet 57, thereby cleaning the product flow control assembly 32, the product line segment 41, the mixing line segment 45, and the dispensing unit 11. After pumping the cleaning solution, the pump 14 may be connected with a container holding water, which is then pumped to flush any residual cleaning solution from the product flow control assembly 32, the product line segment 41, the mixing line segment 45, and the dispensing unit 11. While the dispenser 10 may be cleaned without disassembly, it should be understood by one of ordinary skill in the art that the dispenser 10 may be disassembled for the complete cleaning of each component.
