Abstract

A coffee brewing system and a method of brewing coffee are provided. The coffee brewing system comprises a base stand, an interactive display screen integral with the base stand, a coffee bean roaster, a coffee bean grinder, and a coffee brew chamber. The coffee bean roaster is a horizontally mounted cylinder with helical mixing blades and an electric heat system on a lower surface, which is detachably mounted to the base stand. The coffee bean grinder is a vertically orientated burr grinder and is detachably mounted to the base stand. The coffee bean grinder is positioned below the coffee bean roaster and configured to receive roasted coffee beans exiting the flap of the coffee bean roaster. The coffee brew chamber is detachably mounted to a heating base integral with the base stand.

First claim

1 : A coffee brewing system, comprising:
a base stand having a flat horizontal section, a vertical section circumferentially connected to an edge of the flat horizontal section, an interactive display screen integral with the base stand, a coffee bean roaster mounted on the vertical section of the base stand, wherein the coffee bean roaster is a horizontally mounted cylinder with helical mixing blades, wherein the coffee bean roaster has an electric heat system on a lower surface and a flap on a front surface, wherein the coffee bean roaster is detachably mounted on the vertical section of the base stand, a coffee bean grinder, wherein the coffee bean grinder is a vertically orientated burr grinder detachably mounted on the flat horizontal section of the base stand, wherein the coffee bean grinder is positioned below the flap on the front surface of the coffee bean roaster and configured to receive roasted coffee beans exiting the flap of the coffee bean roaster, and a coffee brew chamber, wherein the coffee brew chamber is detachably mounted to a heating base integral with the flat horizontal section of the base stand.

2 : The coffee brewing system of claim 1 , wherein the coffee brew chamber is a dallah.

3 : The coffee brewing system of claim 2 , wherein the dallah is made of copper.

4 : The coffee brewing system of claim 1 , wherein the coffee bean roaster has a sensor.

5 : The coffee brewing system of claim 4 , wherein the sensor is a temperature sensor.

6 : The coffee brewing system of claim 5 , wherein the temperature sensor detects the temperature inside the coffee bean roaster and is connected with the electric heat system and configured to prevent coffee beans from being burned during roasting.

7 : The coffee brewing system of claim 1 , wherein the coffee brew chamber has a sensor.

8 : The coffee brewing system of claim 7 , wherein the sensor is an overflow sensor.

9 : The coffee brewing system of claim 8 , wherein the overflow sensor detects a liquid in the coffee brew chamber and is connected with the heating base and configured to prevent the liquid from spilling from the coffee brew chamber during brewing.

10 : The coffee brewing system of claim 1 , wherein the helical mixing blades are connected to a motor configured to rotate the helical mixing blades along a central axis.

11 : The coffee brewing system of claim 1 , wherein the horizontally mounted cylinder is made of a glass.

12 : The coffee brewing system of claim 1 , wherein the coffee bean grinder is made of copper.

13 : The coffee brewing system of claim 1 , wherein the heating base comprises a resistive heating element configured to operate at a temperature of 20 to 120° C.

14 : The coffee brewing system of claim 1 , wherein the flap on the front surface of the coffee bean roaster has a handle.

15 : The coffee brewing system of claim 1 , wherein the flat horizontal section of the base stand is circular, and the vertical section of the base stand has a front side and a rear side, wherein the front side is lower than the rear side.

16 : The coffee brewing system of claim 15 , wherein the interactive display screen is on the vertical section of the base stand on the front side.

17 : A method of brewing coffee, comprising:
adding raw coffee beans into the coffee bean roaster of the coffee brewing system of claim 1 ; selecting a brew method from the interactive display screen; roasting the raw coffee beans to form roasted coffee beans, dropping the roasted coffee beans into the coffee bean grinder; grinding the roasted coffee beans to form ground roasted coffee beans; transferring the ground roasted coffee beans into the coffee brew chamber; adding water to the coffee brew chamber; and heating the ground roasted coffee beans and water in the coffee brew chamber to a temperature for a time sufficient to make the coffee.

18 : The method of claim 17 , wherein roasting the raw coffee beans comprises simultaneously heating the electric heat system and rotating the helical mixing blades.

19 : The method of claim 17 , wherein heating the ground roasted coffee beans and water occurs for 5 to 30 minutes.

20 : The method of claim 17 , wherein the method of brewing coffee is a Saudi Arabian method of brewing coffee.
