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.
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.
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.
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.
