Magnetically Driven Beverage Brewing System and Method

Abstract

A coffee brewing system includes a brew vessel adapted to receive water and ground coffee to produce and store a brewed beverage. The brew vessel includes a filter and a magnet stirrer in the lower portion of the brew vessel. The magnet stirrer creates a water vortex for brewing the coffee. The used coffee grounds are allowed to settle on the filter creating a bed of used coffee grounds and the coffee is then filtered through both the bed of used coffee grounds and the filter and collected in a coffee storage container.

Description

TECHNICAL FIELD[0001]The present disclosure generally relate to systems and methods for brewing a beverage. More particularly, the present disclosure relates to systems and methods for brewing high quality hot coffee and cold brew coffee in a rapid and convenient manner.BACKGROUND[0002]Coffee is a very popular drink that is consumed by a huge number of consumers every day. Typically consumers rely on coffee shops, restaurants, and other places that produce brewed coffee in bulk for consumer consumption. In making large quantities of coffee, typical coffee brewing machines are used that pass heated water through a static bed of coffee grounds to produce a coffee beverage that is collected in a coffee container. This is referred to as a drip coffee maker. The static bed of coffee grounds, which grounds are produced by grinding roasted coffee beans, is typically contained within a disposable paper filter held within a funnel.[0003]A static bed of coffee grounds presents numerous proble...

AI Technical Summary

Benefits of technology

[0014]In the preferred embodiment of the present invention, a brew vessel receives water and coffee grounds to produce a brewed beverage. A portion of the walls of the brew vessel are made of a transparent material, such as heat resistant glass, so that the brewing operation of the coffee is visible. The brew vessel includes a reusable filter, preferably conical, disposed in a lower portion of the brew vessel that is used to filter the coffee from the mixture of coffee grounds and water (fluidized slurry). A magnet stirrer in the lower portion of the brew vessel, coupled to a motor below the magnet stirrer, creates a water vortex for mixing the ground coffee and water and at the same time preventing the small particles of the used coffee grounds from clogging the pores of the filter.

[0022]It is another object of the present invention to more effectively extract the flavor of ground coffee.

[0024]It is yet another object of the present invention to more efficiently use the coffee grounds.

[0025]It is another object of the present invention to make cold brew coffee in less time.

[0026]It is also another object of the present invention to provide a coffee machine that can make both hot coffee and cold brew coffee.

Problems solved by technology

A static bed of coffee grounds presents numerous problems that negatively affect the coffee made with known brewing machines according to traditional brewing methods.

It is difficult to maintain the temperature of the heated water while the heated water passes through a static bed of coffee grounds.

The temperature drop of the water temperature passing through the static coffee grounds bed creates a temperature gradient that can negatively affect the quality of brewed coffee produced.

Among other things, the traditional drip coffee can become bitter and acidic.

In addition, exposing the same coffee grounds in the channel causes the water to extract more of the unpleasant chemicals from the coffee grounds and produce undesirable coffee.

Further, a portion of the desirable flavor components contained in the remaining coffee grounds not in the channels are not sufficiently extracted, which results in effectively wasting coffee beans and flavor.

In addition, used coffee grounds are only usable to produce a certain amount of coffee until the coffee produced becomes undesirable in taste.

However, having to constantly reach up to the top of these brewing machines to lift, remove and refill filter trays and filters can be a work safety issue for workers.
