Diagram of a coffee percolator A disassembled coffee percolator A coffee percolator consists of a pot with a small chamber at the bottom which is placed closest to the heat source.

A vertical tube leads from this chamber to the top of the percolator. Just below the upper end of this tube is a perforated chamber. The desired quantity of water is poured into the water chamber of the pot and the desired amount of a fairly coarse-ground coffee is placed in the top chamber.

It is important that the water level be below the bottom of the coffee chamber. The heat source under the percolator such as a range or stove heats the water in the bottom chamber.

Water The patent process essay the very bottom of the chamber gets hot first and starts to boil. The boiling makes bubbles rise up and, using the principle of an airlift pumppush water up the vertical tube then out The patent process essay top of the vertical tube.

From the top of the tube, the water flows out and over the lid of the coffee chamber. Perforations in the lid distribute the water over the top of the coffee grounds.

The water then seeps through the coffee grounds then through the bottom of the coffee chamber.

From the bottom of the coffee chamber, the water drops onto the colder water at the top of the bottom chamber, helping to force water up the tube.

This whole cycle repeats continuously. As the brew continually seeps through the grounds, the overall temperature of the liquid approaches boiling point, at which stage the "perking" action the characteristic spurting sound the pot makes stops, and the coffee is ready for drinking. In a manual percolator it is important to remove or reduce the heat at this point.

Brewed coffee left on high heat for too long will acquire a bitter taste. Some coffee percolators have an integral electric heating element and are not used on a stove. Most of these automatically reduce the heat at the end of the brewing phase, keeping the coffee at drinking temperature but not boiling.

Inventor[ edit ] The percolating coffee pot was invented by American-born British physicist [2] and soldier Count Rumford, otherwise known as Sir Benjamin Thompson — He invented a percolating coffee pot between and following his pioneering work with the Bavarian Army, where he improved the soldiers' diet as well as their clothing.

It was his abhorrence of alcohol and his dislike for tea that led him to promote the use of coffee for its stimulating benefits. For his efforts, inhe was named a Count of the Holy Roman Empireand granted the formal title of Reichsgraf von Rumford.

His pot did not use the rising of boiling water through a tube to form a continuous cycle. The first modern percolator incorporating these features and capable of being heated on a kitchen stove was invented a few years later, inby the Parisian tinsmith Joseph-Henry-Marie Laurens [3].

Its principle was then often copied and modified. There were also attempts to produce closed systems, in other words "pressure cookers". The first US patent for a coffee percolator, which however still used a downflow method without rising steam and water, was issued to James Nason of Franklin, Massachusettsin An Illinois farmer named Hanson Goodrich patented the modern U.

It has the key elements, the broad base for boiling, the upflow central tube and a perforated basket hanging on it. He still describes the downflow as being the "percolating.

Subsequent patents have added very little. Finally, in the world's first electric coffee perculator was invented by British company Russell Hobbs [4] Usage[ edit ] Percolators are popular among campers and outdoorspeople because of their ability to make coffee without electricity.

Non-pressure percolators may also be used with paper filters. Large s-era percolators are still used in the s at community events, church gatherings and other large group activities where large quantities of coffee are needed.

Improvements[ edit ] The method for making coffee in a percolator had changed very little since the introduction of the electric percolator in the early part of the 20th century.

The coffee filter rings were designed for use in percolators, and each ring contained a pre-measured amount of coffee grounds that were sealed in a self-contained paper filter. The sealed rings resembled the shape of a doughnut, and the small hole in the middle of the ring enabled the coffee filter ring to be placed in the metal percolator basket around the protruding convection percolator tube.

Prior to the introduction of pre-measured self-contained ground coffee filter rings, fresh coffee grounds were measured out in scoopsful and placed into the metal percolator basket. This process enabled small amounts of coffee grounds to leak into the fresh coffee.

Additionally, the process left wet grounds in the percolator basket. The benefit of the pre-packed coffee filter rings was two-fold: First, because the amount of coffee contained in the rings was pre-measured, it negated the need to measure each scoop and then place it in the metal percolator basket.

Second, the filter paper was strong enough to hold all the coffee grounds within the sealed paper. After use, the coffee filter ring could be easily removed from the basket and discarded.

This relieved the consumer from the task of cleaning out the remaining wet coffee grounds from the percolator basket.Expository writing is used to convey information.
