One that is not as popular as all the others is the vacuum machine. They come in many shapes and sizes, yet they are more alike than they are different. This system heats the water in the lower chamber creating a water vapor. This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat, the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.
One definition for a machine is a mechanically, electrically, or electronically operated device for performing a task. Thus, a coffee machine can, for all intents and purposes, be defined as a coffee maker or coffee grinder. These coffee machines can be simple to advanced and inexpensive to very expensive. This article will cover coffee makers that make as little as a single cup or as much as 60 cups and are inexpensive to very expensive.
The drip coffee machines are usually electric ones that heat the water and then pump it over the grounds. However, a stove top type is still used. The water is boiled in a tea kettle and poured into a top reservoir with holes in it. A smaller container below holds the coffee grounds, usually with a filter. When the water finishes dripping through to the bottom, the coffee is ready to drink. Both the electric and stove top makers come in many brands and in a wide range of prices. The less expensive ones require a filter, while others may come with a permanent gold-coated coffee filter or other permanent filter.
If you work in a small office, a machine with a small carafe is sufficient. However, you work in a very large office, a machine that can fill a large coffee urn might be what is needed. Another feature that would be useful in this type of environment is a machine with a "time to clean" indicator coupled with a self clean feature. Often, calcium buildup can occur in these machines and an indicator of when the machine needs to be cleaned is important. In a shared environment, it is very likely that responsibilities like cleaning the coffee machine can be ignored due to the phenomenon known as the tragedy of the commons. By having a machine with simplified cleaning measures like an auto-clean, you can avoid the pitfall of nobody taking responsibility to clean.
