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.
Many years ago, a cup of coffee was never easy to make. Coffee beans were being roasted then grounded, placed in a hot pot, and boiled under water. During the 19th to 20th century, people learned that roasting coffee beans was not really necessary, and that adding ground coffee to boiling water was enough to make a delicious drink.
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.
One type of coffee maker that became popular in the 19th century is called a vacuum brewer. It uses the vacuum principle to produce a clear brew. How does it work? Water is heated in the lower vessel until it expands to force the contents through a tube. This tube leads to the upper vessel that contains ground coffee. Once the lower vessel is empty, heat is removed. Vacuum then pulls back the brewed coffee and passes through a strainer in the lower chamber from where it is poured out.
Still in the mid-nineteenth century, percolators with detachable lid covers came out in United States. Water is first heated until it boils. Once boiling, water travels through a metal tube heading to the coffee grounds. Until the brew is saturated with coffee flavor, the process is done over and over again.
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. - 30241
