NZ 762052 TITLE OF THE INVENTION COMMERCIAL FRENCH PRESS COFFEE BREWING AND DISPENSING SYSTEM CROSS-REFERENCE TO RELATED APPLICATIONS This patent application claims the benefit of US. Provisional Patent Application Serial No. 62/554,241 filed on September 05, 2017 and entitled "Commercial French Press Coffee Brewing and Dispensing System," the disclosure of which is hereby incorporated by reference herein in its entirety and made part of the present U.S. utility patent application for all purposes.
BACKGROUND OF THE INVENTION The described invention relates in general to systems and devices for making coffee or other beverages, and more specifically to a large—scale French press type coffee brewing and sing system for use in commercial environments.
A French press coffee maker is a fairly , commercially available coffee brewing device that typically includes a cylindrical pot or reservoir with a plunger and built—in filter screen or mesh that presses hot water through ground coffee. A French press coffee maker tends to work best with coffee of a coarser grind than does a drip brew coffee maker; r, a medium grind of coffee with uniformity and tency throughout is often most desirable for use with such devices. Finer grounds, when immersed in water, have lower permeability, thereby requiring excessive force to be applied by hand to lower the plunger and are more likely to seep through or around the perimeter of the press filter and into the coffee. Additionally, finer grounds tend to over—extract and impart a bitter taste to the coffee.
Using a French press, coffee is typically brewed by placing ground coffee in the empty rical pot and adding hot (e.g., between 93—96°C / l99—205°) water, in proportions of about 30g of coffee grounds to about 500 ml of water, more or less to taste. After stirring the ts, the coffee is y allowed to brew for about two to four minutes. The plunger is pressed to te the grounds and retain them at the bottom of the cylindrical pot. The mesh screen at the end of the piston does not normally ss the coffee grounds, as most French 1004737947 press coffee maker designs leave about 30 mm (1.2 inches) below the piston in its lowest position. If the brewed coffee is allowed to remain in the cylindrical pot with the spent coffee grounds, the coffee may become astringent and bitter, though this is an effect that some users of the French press er ble. The optimum time for brewing coffee is considered to be around four minutes, and some consider the coffee ruined after about 20 minutes. Other approaches, such as cold-brewing, require several hours of contact n the water and the grounds to achieve the desired extraction. After each use, the cylindrical pot should be washed with water and a mild detergent and dried thoroughly.
Although the French press coffee maker is a somewhat common item, the devices tend to be relatively small in size and volume and are intended for making one or two cups of coffee. French press coffee makers are also somewhat difficult to clean due to their basic design and the fact that they must be cleaned after each use, in addition to their small size and volume, makes them impractical for commercial use. Accordingly, there is an ongoing need for a large French press coffee maker that can be used in cial nments such as restaurants and coffee shops.

Other suitable materials may also be used. With regard to using fully assembled coffee maker 100, lift assembly 300 is moved into its lowered positioned using lift knob assembly 323 and grounds chamber assembly 800 is d from lift assembly 300 by sliding it d. Grounds chamber 800 is d (if necessary) and an appropriate amount of ground coffee is added to the basin of component 805. Grounds chamber assembly 800 is returned to lift assembly 300 in the proper position and lift assembly 300 is moved to its raised positioned (again using lift knob assembly 323) wherein seal ring 806 engages lower seal ring 716 on brew chamber assembly 700. An appropriate volume of heated water is added to brew r ly 700 and mixed with ground coffee, which is then allowed to brew for a predetermined period of time.
Lid assembly 600 is then positioned on brew chamber assembly 700 and press handle 652 is depressed either manually or in some embodiments of this invention, in an automated manner. As press handle 652 is depressed the filter screen in frame 606 pushes the coffee grounds out of sion in the heated water and back into the basin of component 805.
As press handle 652 is depressed, both wiper seals 604 and 610 to act together to prevent the coffee grounds from bypassing the filter screen. After coffee has been dispensed from coffee maker 100, press release button 644 is depressed allowing the filter screen to remain on top of the spent coffee grounds and second wiper seal 610 to be pulled upward. As wiper seal 610 moves upward, it acts as a squeegee that cleans the edges of the brew chamber by removing oils and any remaining coffee grounds. Brewed coffee is dispensed from the brew chamber by way of a dispensing system that includes spout tube 846, which (in some embodiments) when not in use is positioned against the curved outer wall of basin 802. The curved geometry of spout tube 846 allows it to be wrapped around basin 802 to prevent damage to spout tube 846 when not in use.
By pulling outward on handle 812, an internal valve system is opened (see ) and brewed coffee flows out of basin 805. Releasing handle 812 causes the internal valve system to return to its closed position and coffee stops flowing from basin 802.
