Abstract
Systems and methods for submerging coffee within water in a chamber directly below a filter, creating a vacuum within the chamber, removing carbon dioxide through the filter while preventing the formation of carbonic acid, and creating another vacuum within the chamber.
Claims18
A system for vacuum brewing coffee comprising:
- a container including first threads and a lip positioned below the first threads;
- a lid with a lower opening, upper opening, and second threads, the second threads being configured to be coupled with the first threads;
- a filter being configured to be positioned between a distal end of the container and a proximal end of the container, the filter being configured to form a first chamber between a lower surface of the filter and the distal end of the container, and a second chamber between an upper surface of the filter and the proximal end of the container, the filter having a rim configured to be positioned on the lip and secured in place via the lower opening, the rim defining the upper surface of the filter;
- ground coffee positioned within the first chamber, the filter being configured to filter the ground coffee and allow for fluids to flow across the filter, wherein the ground coffee includes carbon dioxide, wherein an entirety of the first chamber is configured to be filled with fluid during a brewing process, wherein the ground coffee is configured to be positioned directly below the filter during the brewing process, and a lower portion of the second chamber and the rim of the filter is configured to be filled with the fluid during the brewing process, wherein the ground coffee is submerged directly below the filter for an entirety of the brewing process;
- a one way valve positioned on the upper opening of the lid and configured to allow air and gases to flow from the second chamber across the one way valve into the atmosphere, the one way valve being configured to restrict the flow of air and gases from the atmosphere across the one way valve into the second chamber, wherein the ground coffee is positioned directly below the filter and in an annulus between the filter and the inner surface of the container during the brewing process;
- a vacuum device configured to be positioned on the one way valve move air and gases from the second chamber into the atmosphere across the one way valve to lower a pressure within the second chamber below atmospheric pressure in chamber during an entirety of the brewing process to lower a boiling point of the water to allow the ground coffee to be brewed without an external heating source, the vacuum device being configured to activate the one way valve, the vacuum device being positioned above the rim of the filter, and the one way valve is positioned axially between the vacuum device and the upper opening of the lid, wherein the first chamber is larger than the second chamber.

- forming a second chamber between an upper surface of the filter and a proximal end of the container, the filter having a rim configured to be positioned on the lip and secured in place via the lower opening, the rim defining the upper surface of the filter;
- filling an entirety of the first chamber and above the rim of the filter with fluid;
- submerging the ground coffee directly below the filter for an entirety of a brewing process;
- coupling a one way valve with the lid;
- controlling the flow of gases within the second chamber during the brewing process via the one way valve, wherein the one way valve allows gases to flow from the second chamber across the one way valve into an atmosphere and restricts the flow of gases from the atmosphere across the one way valve into the second chamber, wherein the ground coffee is positioned directly below the filter and in an annulus between the filter and the inner surface of the container during the brewing process;
- positioned a vacuum device on the one way valve;
- moving, via the vacuum device, gases from the second chamber into the atmosphere across the one way valve to lower a pressure within the second chamber below atmospheric pressure during the brewing process to lower a boiling point of the water to allow the ground coffee to be brewed without an external heating source, wherein the vacuum device being configured to activate the one way valve, the vacuum device being positioned above the rim of the filter, and the one way valve is positioned axially between the vacuum device and the upper opening of the lid;
- removing the one way valve from the lid;
- filtering the ground coffee positioned within the first chamber and allowing fluids to flow across the filter when pouring brewed coffee, wherein the first chamber is larger than the second chamber.
