Cold coffee brewer
View Patent ↗A cold coffee brewing device reduces the time required to produce cold brewed coffee. The cold brewer includes a container, preferably transparent, and an elongated brewing material holder suspended from a lid of the container. The brewing material holder is enclosed in a mesh to retain brewing material in the brewing material holder. In one embodiment, the mesh is a fine nylon mesh or a 75 micron opening nylon mesh. The lid includes a mechanism to rotate the brewing material holder. The container is filled with water and the brewing material holder is filled with brewing material. Movement of the brewing material submerged in water substantially reduces the time required for cold brewing.

wherein the drive assembly includes an electric motor,
wherein the drive assembly includes a coupler having spaced bars, and
wherein the beverage material holder includes corresponding teeth configured to align and engage the bars to mechanically couple the drive assembly to the beverage material holder.
2. The cold coffee brewer of Claim 1 , wherein the drive assembly includes an electric motor.
3. The cold coffee brewer of claim 2 , wherein the drive assembly includes reduction gears configured to couple the electric motor to the brewing material holder.
4. The cold coffee brewer of claim 2 , wherein the drive assembly includes a belt drive configured to couple the electric motor to the brewing material holder.
5. The cold coffee brewer of claim 1 , wherein the teeth are generally triangular in shape.
6. The cold coffee brewer of Claim 1 , wherein the drive assembly is configured to rotate the brewing material holder such that the brewing material holder oscillates in a range of between 90 degrees and 270 degrees of rotation at a frequency of between 30 and 90 cycles per minute.
7. The cold coffee brewer of claim 6 , wherein the drive assembly is configured to rotate the brewing material holder such that the brewing material holder oscillates through about 120 degrees of rotation.
8. The cold coffee brewer of Claim 1 , wherein the drive assembly is configured to rotate the brewing material holder such that the brewing material holder oscillates at a frequency of about 60 cycles per minute.
9. The cold coffee brewer of Claim 1 , wherein the container is made from a transparent material.
10. The cold coffee brewer of Claim 1 , wherein the mesh is selected from the group consisting of a 75-micron opening nylon mesh, a metal mesh, a paper mesh material, and filter paper.
11. The cold coffee brewer of claim 10 , wherein the mesh is a metal mesh material.
12. The cold coffee brewer of claim 11 , wherein the mesh is a 75-micron opening nylon mesh.
13. The cold coffee brewer of Claim 1 , wherein the beverage material holder includes a skeleton frame comprising vertical members and connecting circular members.
14. The cold coffee brewer of claim 13 , further comprising blades that project radially from the skeleton frame into an interior of the beverage material holder.
15. A cold coffee brewer, comprising:
a container having an open top;
a container lid configured to cover the open top;
a brewing material holder configured to hold ground brewing material and to be suspended from the container lid and into an interior of the container, having a sidewall with open regions;
a mesh material covering the open regions of the brewing material holder; and
a drive assembly positionable on the container lid and configured to be mechanically coupled to and rotate the brewing material holder in an oscillating manner;
wherein the drive assembly includes a coupler including spaced bars; and
wherein the beverage material holder includes corresponding teeth configured to align and engage the bars of the coupler to mechanically couple the drive assembly to the beverage material holder.
16. The cold coffee brewer of Claim 1 , wherein the beverage material holder includes
a bottom cap, and
fins extending outward from an exterior of a bottom of the bottom cap.
17. A cold coffee brewer, comprising:
container means for holding liquid, having an open top;
cover means for covering the open top;
holding means for holding ground brewing material and for being suspended from the container lid and into an interior of the container means;
mesh means for covering openings in a sidewall of the holding means; and
drive means for mechanically coupling to and rotating the holding means, positionable on the container lid;
wherein the drive means includes coupling means including spaced bars; and
wherein the holding means includes corresponding teeth configured to align and engage the bars of the coupling means to mechanically couple the drive means to the holding means.
18. The cold coffee brewer of claim 17 , wherein the drive means is a means for rotating the holding means in an oscillating manner.
