Coffee Maker & It's Types

Coffee Machines or Coffee Makers are a very important product in the cooking world. They are used to produce and infuse coffee. Coffee makers use different kinds of brewing principles to make coffee. According to these principles coffee makers are of many types.

In the past centuries, it was very simple to infuse or brew a cup of coffee. Coffee beans which were grounded and roasted were placed in a pan or a pot, with a lid attachment in which hot water was poured and infusion process was initiated.

The first country to introduce the brewing or infusion process to the world in the year 1710, was France. The process was to let the grounded coffee submersed in hot water, in a closed linen bag. This resulted in infusing or brewing of the coffee. The strength of the coffee depended on the time of infusion. Later the idea of not boiling coffee gained a lot of acceptance by the people.

The size of the grounded coffee determined its quality and taste, for example – too fine coffee let the water not drip from the filter and if too coarse, the coffee was very weak in taste. The ‘pumping percolator’ was also developed by a French Inventor- this contained a chamber at bottom which had boiling water. This water was forced into a tube by itself and then ‘percolated’ the grounded coffee.

 

Types of Coffee Makers

 

These type of coffee makers work on the principle of vacuum. For example, there was a machine which was invented in 1840 – The Napier Vacuum Machine. Vacuum brewers were highly popular at a time for producing or infusing a clear brew. This worked on a principle that the lower vessel contained water which was heated, which led to the expansion of the vessel and the contents were moved into the upper vessel through a narrow tube. The upper vessel contained grounded coffee.

The vacuum which had occurred, forced the coffee to the lower vessel. It uses technique like balance siphon. Later the automatic vacuum coffee brewer was invented and modified into Faberware Coffee Robot.

  • Percolators

In this type of coffee makers, the boiling pot is used to heat water. This boiling pot comes with a removable lid. Water is heated until it is moved or forced into a brewing or infusing basket, which contains the grounded coffee through a metal tube. The extracted liquid which is dripped and collected into the pot is drained from the brew basket. This cycle is repeated continuously until the coffee reaches its adequate strength and colour.

  • Moka Pot

The Moka Pot uses the technique of passing hot water through the grounded coffee which is pressurised by the steam to produce or infuse a good quality coffee. This coffee maker can be considered as a stove top coffee maker. It is most commonly used in Latin America and Europe. This pot is also displayed in design and modern industrial art museums.

  • Electric Drip Coffeemakers

It is also called as a dripolator. It produces coffee by passing water from a cold reservoir to a heating chamber through a flexible hose. The heating chamber is used to heat water. The water which is already heated moves in the machine ( based on the principle of thermosiphon). The heated water moves onto the grounded coffee beans. Then the coffee is filtered and collected into a carafe.

  • Espresso Machine

It is a single-cup or a single-serve coffee maker. It is very popular. It delivers the coffee rapidly, and the colour and the strength of the coffee depends on the individual drinking it. It can be used in commercial spaces as well as in homely environment.
