Description

[Technical field]

[0001] Disclosed below are methods and devices for dissolving or emulsifying mixtures from particulate matter using fluids in a rotating fluid device. More particularly, disclosed are rotating fluid devices for hot and cold brew coffee extraction and beverage infusion, and methods for coffee extraction and / or beverage infusion using such devices.

[0002] The method and the device are particularly suitable for extracting coffee in the so-called cold brew process. Furthermore, the method is suitable for infusing beverages such as cocktails or drinks. [Background technology]

[0003] In principle, preparing coffee or tea beverages from ground coffee beans or tea leaves, respectively, is a process of dissolving and / or emulsifying the mixture from the granulation. Conventional methods for brewing coffee include drip brewing, espresso extraction, and immersion brewing, which involve different techniques of passing water through or holding water around the coffee grounds. Cold brewing, a subcategory of immersion brewing, involves steeping the coffee grounds in cold or room temperature water for extended periods of time, typically 12-24 hours. While cold brewing produces a unique flavor profile with reduced bitterness and acidity, it can be time consuming and may not efficiently extract all the desired mixtures from the coffee grounds. In contrast, hot brewing methods can extract mixtures more efficiently, but may result in undesirable flavors due to the higher extraction temperature. Beverage infusion techniques, such as those used for cocktails or other drinks, often involve simple mixing or steeping of the ingredients, which may not maximize the extraction of flavors and mixtures from the ingredients. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to address the limitations and shortcomings of conventional coffee brewing and beverage infusion methods. This object is solved by a method according to independent claim 1 and a device according to independent claim 35. Further embodiments of the invention are defined by the dependent claims and the following description. [Means for solving the problem]

[0005] By utilizing a rotating fluid device, the present invention provides an efficient and versatile method for extracting mixtures from particulates such as coffee or tea. The unique geometry and rotational motion of the device creates fluid rotation, which promotes efficient extraction and emulsification of mixtures from particulates such as coffee grounds or tea leaves. The present invention is suitable for both hot and cold brew coffee extraction, providing improved extraction efficiency, reduced brewing time, enhanced flavor profile, and versatility of brewing temperature. Additionally, the present invention can be used to infuse beverages such as cocktails or other drinks, providing improved flavor extraction and infusion capabilities.

[0006] The present invention provides a rotating fluid device and method for efficiently dissolving or emulsifying mixtures from particulate matter such as coffee or tea, and for infusing beverages such as cocktails or other drinks, in coffee extraction processes, both hot and cold brewing. The method employs a holder for particulate matter having at least one inlet for receiving fluid into the holder and at least one outlet for discharging fluid from the holder, and at least one flow path adjacent to said holder. Preferably, a container having a specific geometric shape, such as a conical or square shape, is provided to contain the fluid.

[0007] The present rotating fluid device and method for dissolving and / or emulsifying mixtures from particulates such as coffee or tea represents a novel approach to beverage extraction. This innovative system uniquely combines the principles of percolation and immersion brewing to offer a distinct set of advantages over traditional brewing methods.

[0008] In percolation brewing, water is passed through a bed of granules, extracting the mixture as it flows. This method ensures efficient extraction and a distinct flavor profile. Immersion brewing, on the other hand, involves steeping the granules in water for a longer period of time, allowing for a more complete extraction process, resulting in a richer, more complex flavor.

[0009] The present rotating fluid device does the best of both methods by providing a holder for the granules with at least one inlet and outlet for fluid movement. As the holder rotates, boundaries and / or shear layers are created in the fluid, causing it to move within at least one of the provided flow paths. This movement carries the fluid through the inlet into the holder, effectively permeating the fluid through the granules. At the same time, the same fluid is reused in the process, mimicking the immersion brewing technique. This unique combination ensures efficient extraction, a distinct flavor profile, and a richer, more complex beverage.

[0010] By integrating both percolation and immersion brewing techniques into a single device, the rotating fluid device provides a versatile and adaptable brewing solution. This innovative method allows users to achieve optimal extraction efficiency and customize the flavor and texture of the resulting beverage, differentiating it from other brewing methods currently on the market.

[0011] The present invention utilizes a rotational movement of a holder about an axis, which creates boundaries and / or shear layers in the fluid, causing movement of at least a portion of the fluid within at least one of said flow paths, which movement causes at least a portion of said fluid to enter at least one of said inlets. The present rotational fluid device allows for more efficient extraction and emulsification of the mixture from the particulate matter, resulting in improved extraction efficiency, reduced brewing time and enhanced flavor profile.

[0012] The present invention is versatile and capable of brewing both hot and cold coffee, as well as infusing beverages. In one embodiment, the rotating fluid device includes a heater, which can be used to heat fluids for brewing hot coffee or other applications requiring high temperatures. The method and device provide a novel approach to coffee brewing and beverage infusion, overcoming the limitations and shortcomings of conventional brewing and infusion methods.

[0013] The present invention provides a adaptable and versatile brewing system capable of handling a variety of granular materials such as coffee, tea, and other infusible substances, in particular by allowing the user to customize parameters such as rotation speed, temperature, brewing time, etc.

[0014] The present invention incorporates innovative features such as impeller geometry, fluid aeration, and various heating mechanisms at the inlet to optimize the extraction or emulsification process and enhance the flavor profile, texture, and sensory qualities of the resulting beverage.

[0015] The present invention offers a wide range of container geometries and holder designs, including integrated filters and various valve configurations, to accommodate different brewing techniques and particulates to improve overall brewing efficiency and user experience.

[0016] The present rotating fluid device and method offer significant versatility in beverage brewing and preparation. In addition to traditional water-based brewing, the device can be utilized to brew coffee directly into milk or milk substitutes such as almond milk, soy milk, or oat milk. This feature allows users to make a wide variety of beverages, including lattes, cappuccinos, and other specialty coffee drinks, using a single brewing step.

[0017] One notable advantage of the rotating fluid device is its ability to aerate milk or milk substitutes to produce foam even when the fluid is cold. The device achieves this by creating boundaries and / or shear layers in the fluid during the extraction process, entraining air in the fluid and producing the desired foamy texture. This aeration enhances the mouthfeel of the resulting beverage, providing a richer, more enjoyable drinking experience.

[0018] Additionally, the present rotational fluid device and method may be adapted to operate under vacuum conditions by incorporating a vacuum pump connected to the vessel. Operating the device under vacuum may provide several benefits, such as preventing foam formation in the beverage when a smoother texture is preferred, or improving extraction efficiency for certain types of particulate matter. The vacuum setup provides the user with additional control over the extraction process as well as the ability to customize the texture and flavor profile of the resulting beverage.

[0019] In summary, the present rotating fluid device and method provides a highly adaptable and versatile brewing solution suitable for making a variety of beverages ranging from traditional coffee extracts to specialty drinks with milk or milk substitutes. The device's ability to aerate the fluid and potential to operate under vacuum conditions widens the range of possibilities for users to create their own personal beverages, differentiating it from traditional brewing methods.

[0020] The present invention incorporates advanced technologies such as magnetic or fluid bearings, programmable control systems, and integrated sensor systems to provide precise control over the extraction or infusion process and ensure consistent, high quality results.

[0021] The present invention addresses limitations and shortcomings of traditional brewing and infusion methods by utilizing a rotating fluid device to create fluid rotation that enhances the extraction or emulsification process, shortening brewing times and improving extraction efficiency.
