03 Sep 09 Find Out Some Interesting Facts About Coffee Makers

The aromatic property of coffee has allowed people to use it in so many ways. It has helped people stimulate their senses and made conversations go for hours in cafeterias. And most of you are not eve aware that coffee has been taken to higher form of usage in clinics, not as a beverage, but as a substance for testing the olfactory nerve of patients.

Years back, people shed their sweat and blood before a cup of coffee can be produced. It involves a lot of processes, from roasting, to grounding and boiling. Then on the 19th and 20th century, people learned that it is pointless to roast the coffee beans because it produces the same delicious drink even if it’s just plain ground coffee.

The invention of modern coffee makers made life easy for anyone who considers himself a coffee addict. Coffee makers are home appliances used to brew coffee without the need to boil water in a separate container. Commonly, it undergoes the so-called automatic drip-brew process. The paper or metal filter inside its funnel is filled with coffee grounds, then it is set over a glass or coffee pot. In another chamber, cold water is boiled, and then directed into the funnel.

Vacuum brewers, which were grounded in vacuum principle, were first used in the 19th century to create clear coffee. On its lower vessel, heat is applied on the water to increase the pressure inside. The increasing pressure now forces the water through a tube that opens into the upper vessel. On the upper vessel, coffee grounds are stored, and the water that passes to it absorbs their flavor. When the lower vessel has no more water, heat is removed. The absence of heat lowers the pressure in the chamber, forcing the water from the upper chamber to go back to the lower vessel. It then passes through a filter, and then poured out.

Another coffee maker was introduced in the mid-19th century in the United States. Percolators are first filled with water and subjected to heat. When the water boils, water travels through a metal tube going into the coffee grounds. The same mechanism is done repeatedly until the coffee grounds run out of flavors.

Electric drip coffee makers or dripolators are another type of coffee brewing device that uses the principle called thermosiphon. In this type, there is a reservoir for cold water. Water from this reservoir goes into a flexible hose that leads to an aluminum heating chamber. This chamber moves the heated water into another hose by way of thermally-induced pressure and siphoning effect. From this hose, water goes to a spray head, and then to the ground coffee. Coffee then passes through a filter, and then poured out.

Coffee makers have been designed in different ways through the years. All these coffee makers made coffee experience incomparable from other beverages.
