What is the primary extraction principle utilized by the automatic drip coffee maker?
Answer
Percolation (Gravity)
The automatic drip coffee maker operates based on the principle of percolation, which relies on gravity for extraction. In this semi-automatic process, internal heating elements warm the water to the appropriate temperature. This hot water then travels upwards and is slowly dripped over the bed of coffee grounds held within a filter basket. Gravity pulls the water down through the grounds, extracting the flavors, and the resulting brewed coffee subsequently drips down into a carafe positioned below, often resting on a warming plate to maintain temperature.
