Description

Technical Field

[0001] The following discloses a method and a device for dissolving or emulsifying a mixture from particulate matter using a fluid within a rotating fluid device. More particularly, a rotating fluid device for high-temperature and low-temperature brew coffee extraction and beverage infusion, and a method for coffee extraction and / or beverage infusion using such a device are disclosed.

[0002] The present method and device are particularly suitable for extracting coffee in a so-called low-temperature brew process. Further, the present method is suitable for infusing beverages such as cocktails or drinks.

Background Art

[0003] In principle, preparing coffee or a tea beverage from ground coffee beans or tea leaves respectively is a process of dissolving and / or emulsifying a mixture from particulate matter. Conventional methods for brewing coffee include drip brewing, espresso extraction, and immersion brewing, which involve different techniques of passing water through coffee powder or holding water around coffee powder. Low-temperature brewing, a subcategory of immersion brewing, involves soaking coffee powder in cold or room-temperature water for a long time, typically 12 to 24 hours. While low-temperature brewing produces a unique flavor profile with reduced bitterness and acidity, it can be time-consuming and may not efficiently extract all desired mixtures from coffee powder. In contrast, high-temperature brewing methods can extract mixtures more efficiently but may result in undesired flavors due to higher extraction temperatures. Beverage infusion techniques, such as those used in cocktails or other drinks, often involve simply mixing or steeping the ingredients, which may not maximize flavor and mixture extraction from the ingredients.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The object of the present invention is to address the limitations and disadvantages of conventional coffee brewing and beverage infusion methods. This object is solved by the method described in independent clause 1 and the device described in independent clause 35. Further embodiments of the present invention are defined by the dependent clauses 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 granular materials such as coffee or tea. The unique geometric shape and rotational motion of the device generate fluid rotation, which facilitates the efficient extraction and emulsification of mixtures from granular materials such as coffee grounds or tea leaves. The present invention is suitable for coffee extraction in both high-temperature and low-temperature brewing, providing improved extraction efficiency, reduced brewing time, an enhanced flavor profile, and versatility in brewing temperature. Furthermore, 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 rotary fluid device and method for efficiently dissolving or emulsifying a mixture from granular material such as coffee or tea, and for brewing beverages such as cocktails or other drinks, in both high-temperature and low-temperature coffee extraction processes. The method of the present invention employs a holder for granular material having at least one inlet for receiving fluid into the holder and at least one outlet for releasing fluid from the holder, as well as at least one flow path adjacent to the holder. Preferably, a container having a specific geometric shape, such as a conical or square shape, is provided for holding the fluid.

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

[0008] In percolation brewing, water passes through a bed of granular material, extracting the mixture as it flows. This method ensures efficient extraction and a distinct flavor profile. On the other hand, immersion brewing involves soaking the granular material in water for a longer period, allowing for a more complete extraction process and resulting in a richer, more complex flavor.

[0009] This rotating fluid device performs the best of both methods by providing a holder for granular materials having 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 the provided at least one channel. This movement carries the fluid into the holder through the inlet and effectively permeates the fluid through the granular material. At the same time, the same fluid is reused in this process, mimicking the immersion extraction 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, this rotary fluid device offers a versatile and adaptable brewing solution. This innovative method allows users to achieve optimal extraction efficiency and customize the resulting beverage's flavor and texture, setting it apart from other brewing methods currently on the market.

[0011] The present invention utilizes the rotational motion of a holder around an axis, which creates boundaries and / or shear layers in the fluid, causing the movement of at least a portion of the fluid within at least one of the flow channels, and this movement causes at least a portion of the fluid to enter at least one of the inlets. This rotating fluid device enables more efficient extraction and emulsification of mixtures from granular material, 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 rotary fluid device includes a heater, which may be used to heat the fluid for brewing hot coffee or other applications requiring high temperatures. The method and device offer 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 versatile and adaptable brewing system that can handle a variety of granular materials, such as coffee, tea, and other brewable substances, by allowing the user to customize parameters such as rotation speed, temperature, and brewing time.

[0014] This invention incorporates innovative features such as the geometric shape of the impeller at the inlet, fluid aeration, and various heating mechanisms to optimize the extraction or emulsification process and enhance the resulting flavor profile, texture, and perceived quality of the beverage.

[0015] The present invention provides a wide range of container geometric shapes and holder designs, including integrated filters and various valve configurations, to accept different extraction techniques and granular materials, thereby improving overall extraction efficiency and user experience.

[0016] This rotary fluid device and method offers remarkable versatility in beverage extraction and preparation. In addition to conventional water-based extraction, the device can be used to directly extract coffee into milk or milk substitutes such as almond milk, soy milk, or oat milk. This feature allows users to create a wide variety of beverages, including lattes, cappuccinos, and other specialty coffee drinks, using a single extraction process.

[0017] One of the notable advantages of this rotating fluid device is its ability to aerate milk or milk substitutes to create 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, incorporating air into the fluid and creating the desired foamy texture. This aeration enhances the mouthfeel of the resulting beverage, providing a richer and more enjoyable drinking experience.

[0018] Furthermore, this rotary fluid device and method can be adapted to operate under vacuum by incorporating a vacuum pump connected to a container. Operating the device under vacuum can offer several benefits, such as preventing foam formation in beverages when a smoother texture is preferred, or improving extraction efficiency for certain types of granular materials. The vacuum setup provides the user with additional control over the extraction process and the ability to customize the texture and flavor profile of the resulting beverage.

[0019] In summary, this rotary fluid device and method provides a highly adaptable and versatile brewing solution suitable for producing a wide range of beverages, from conventional coffee extracts to specialty drinks with milk or milk substitutes. The device's ability to aerate fluids and its potential to operate under vacuum expands the range of possibilities for users to create their own personalized beverages, distinguishing it from conventional 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 leaching process and ensure consistent high-quality results.

[0021] The present invention addresses the limitations and disadvantages of conventional leaching and extraction methods by generating fluid rotation using a rotating fluid device to enhance the extraction or emulsification process, shortening the leaching time, and improving the extraction efficiency.
