Percolator Coffee

How does a Coffee Machine work?

Almost all coffee machines work in a similar manner. There is water that is boiled that is made to pass through freshly grounded coffee and as it does so the coffee machine mixes the two thoroughly. The liquid passes through a filter so that the solid particles are drained out and what is left is the coffee machine concoction.

There are different kinds of coffee machines and each works in a slightly different manner. A percolation coffee machine is a design in which the heating element is in the pot. The boiling water becomes steam that pushes the water out of the pot and it passes over the basket that contains grounded coffee. This type of machine is cyclic in nature and the brewed coffee falls back into the pot only to be steamed again till the brewing is complete.

The Drip Coffee machine uses gravity for the brewed coffee to fall into the pot. The water is stored in a reservoir on top and as it begins to boil, it is passed over a measured amount of coffee. The coffee and water mix and pass through a filter at the bottom before the brewed coffee drips into the coffee machine pot.

A Commercial Coffee machine also uses the technology similar to that of drip machines, albeit high in capacity. The coffee is held in a filter that is placed between the water reservoir and the pot. The additional aspect of a commercial coffee machine is also the dispenser that allows for single cups of different sizes to be dispensed.
