## Background
TECHNICAL FIELD
The present invention relates generally to the field of food preparation and, more particularly, to a frozen beverage dispenser.
BACKGROUND
Modern food preparation often includes preparation outside of a typical kitchen environment. As such, techniques have been developed for food preparation at, for example, catered events. Similarly, modern beverage preparation also often includes preparation outside of a fixed-location bar. For example, at catered events, one or more temporary beverage preparation workstations typically include items routinely found at full-service bars.
Blended beverages require additional equipment, which typically require access to electricity. In temporary beverage workstations, access to electricity can dictate suitable locations to establish such temporary beverage workstations. Most typical temporary beverage stations can only accommodate a small blender, suitable for lower quantity production. Low quantity production can result in customers dissatisfied with long wait times.
Full fixed-location bars also frequently have a machine dedicated to make frozen beverages, especially margaritas. Temporary beverage workstations at events where high margarita consumption is expected typically do not include a dedicated margarita machine. Instead, typical setups use pre-made margaritas stored in a cooler or other container.
But storing margaritas (and other frozen/blended beverages) makes the beverage quality and consistency difficult to maintain. For example, in some cases, the alcohol does not get mixed properly with the other beverage components. Further, in some cases, the frozen and less-frozen parts of the mixture do not blend well together and tend to separate in storage. Poorly blended drinks can result in dissatisfied customers.
In some cases, temporary beverage stations include portable margarita machines. But typical portable margarita machines are bulky, difficult to use, consume a lot of electricity, and are expensive. Moreover, non-commercial uses are usually cost-prohibitive.

In the illustrated embodiment, tap handle 1210 is more offset from the neutral position than the “blend” position, away from beverage port 1206, the motor is ON, and flow from spout 704 is ON. In the illustrated embodiment, the distal end of magnetic bar 1212 is moved away from contact 1216 by a distance 1222. Distance 1222 can be configured based on the particular characteristics of contact 1216 and magnetic bar 1212. Thus, FIG. 12 illustrates one configuration of control inputs and control states for the disclosed embodiments, in accordance with one embodiment.
Thus, generally, system 100 and the other embodiments disclosed herein offer a number of technical advantages over other methods and systems. As described above, prior art systems typically suffer from various challenges. For example, typical systems that can support a high-capacity are not suitable for portable operation, while portable systems are typically unable to provide high-capacity. Similarly, typical systems that can maintain an even consistency and frozen/blended state throughout the beverage are not suitable for portable operation. But typical beverage portability systems cannot adequately maintain an even consistency and/or frozen/blended state throughout the beverage. The disclosed embodiments overcome these and other challenges associated with prior art systems and methods.
For example, the disclosed embodiments can be configured to provide consumers with increased blended beverage volume over conventional portable beverage storage/production approaches. Moreover, the disclosed embodiments can also be configured to provide an easy way to pour with the proper mixture because every pour will trigger the blender to recirculate the ice and liquids to create the perfect consistency in a drink.
Additionally, the disclosed embodiments can be configured with a cone-shaped inner sleeve, which offers a better cyclone mixing effect than traditional multi-gallon blenders, especially portable blenders and portable storage/production approaches. Additionally, the disclosed embodiments can be configured with improved ice packs and ice storage, which keeps the frozen beverages cooler and more-consistently frozen than typical portable storage/production systems.
Thus, generally, the disclosed embodiments provide superior mixing and blending as the frozen beverages are dispensed. The user operation of the tap handle causes the disclosed embodiments to blend the frozen beverage and then dispense the blended beverage with each pour, an advancement over typical frozen beverage dispensers. Additionally, the disclosed embodiments are generally configured for ease of portability, providing superior blended beverages in locations where a typical fixed-location frozen beverage system is impractical. Moreover, the disclosed embodiments are configured for cost-effective portable frozen beverage dispensation, increasing user satisfaction while maintaining high quality for the ultimate consumer of the frozen beverage.
Additionally, the disclosed embodiments can be configured with a see-through gauge allowing a user to check volume levels of the beverage mixture without having to open the lid and release the cold air stored inside the system. Additionally, the disclosed embodiments can be configured with a stand configured with a sound system, allowing the user to play music through the base. These additional features enhance the user experience and contribute to the atmosphere in the location where the disclosed embodiments are employed.
One skilled in the art will appreciate that variations of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Additionally, various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, which are also intended to be encompassed by the following claims.
