Coffee Makers: Learn A Number Of Interesting Facts

By April Kerr

Coffee is one of the most aromatic substances that humans ever discovered. In clinical areas, it is often used to test the sense of smell of neurologically impaired patients. In offices and homes, it is used to awaken the senses and keep you on the go. In cafeterias, it is often used for relaxation and making conversations. No matter what purpose coffee has for you, it is quite clear that coffee is already part of everyone's lifestyle.

A cup of coffee used to be extremely laborious to make. First it was roasted. Then people would grind it until it turns into fine particles. After this, they can now put it under a boiling water to make a delicious coffee drink. During the 19th and 20th century, people have stopped roasting coffee. This is because they learned that whether you roast the coffee beans or not, you would still get the same taste out of it.

Coffee makers have allowed coffee enthusiasts to make coffee the easier way. Unlike traditional brewing, coffee makers don't need an outside source of boiled water to make a cup of coffee. Inside it are two chambers: one for the funnel containing the coffee grounds, and another for the boiling water. Boiled water goes into the filter-lined funnel to create a flavorful coffee drink, a process called automatic drip-brew.

In the 19th century, vacuum brewers came into existence and became renowned. It has a lower and an upper chamber that works using the vacuum principle. In the lower chamber, water is heated first. The rising temperature causes increase in pressure, pushing the water out through a tube that leads to the upper chamber. Heat is then removed once the lower chamber runs out of contents. Meanwhile in the upper chamber, the coffee grounds are kept, and once water reaches them, their flavors are extracted. After heat is removed, vacuum pulls the brew back into the lower chamber, where the coffee is strained and then 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.

Another type of coffee maker works through another principle called thermosiphon. These coffee makers are known as electric drip or dripolators. Cold water from its storage passes into a hose that opens into the heating chamber. By way of pressure produced from heat and siphoning effects, water moves into a spray head while passing through a separate hose. From the spray head, water goes to the ground coffee. It is then filtered and then poured out.

Through the years, many coffee maker designs were released by various manufacturers. All of these allowed people to experience coffee like no other beverage can.
