Brewing Process
Reference Drawings
Step 1 Ascent of the piston
The ground coffee and the water are dispensed into the
brew chamber during the ascension of the piston. This
compresses the air in the cylinder and forces it through the
coffee mixture in the brew chamber thereby agitating the
brewing coffee.
Step 2 Pauses
Once the piston has reached its top dead point, it will pause to
allow the coffee to brew to the appropriate strength. There will
be one shot of water before the descent to rinse the chamber.
Step 3 Descent of the piston
The descent of the piston will create a vacuum thereby extracting
the coffee from the grounds through the filter paper and into the
cylinder. One last pause will be to allow all the coffee to drip from
the brew chamber.
Step 4 Product delivery
The piston follows its course heading to its low dead point.
Distribution of coffee through the spout begins once the piston is
below the coffee exit. Meanwhile, the brew chamber lifts to allow
the paper to advance thereby discarding the spent grounds into
the waste chute.
