Coffee has been part of anyone’s lifestyle. In cafeterias, offices, homes, or just about anywhere, it has evidently been present either as a plain beverage to awaken you, or as a more useful substance in the field of medicine. Since it’s is one of the most commonly aromatic substance, doctors and nurses have used it in hospitals to test the olfaction of an individual.
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.
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.
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.
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.
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.
Manufacturers have made so many coffee maker designs when the years passed, and all of these have made a truly remarkable coffee experience for people.
