How Does Machine Espresso Work?
Machine espresso uses precision pressure and incredible filter technology to produce the delicious coffee we enjoy. How exactly does it work?
In order to make espresso hot water is forced under high pressure through finely ground coffee. The process is similar to that of making drip coffee. However the pressure is the primary difference.
The Head of the Group
As the name implies, the group head is the place you place your portafilter when brewing espresso. It is responsible for dispersing the water into the portafilter and controlling the pressure of the resulting extraction. There are numerous kinds of group heads, each with its own advantages and disadvantages. Some are focused on temperature stability, others on pre-infusion capabilities, while others are designed to control the lever. Some have a combination, like the E61. This is a preferred choice for baristas since it provides multiple benefits in one package.
As you can see from the image above the head of the group is fitted with several notches. The portafilter is placed into these notches and twist the head to lock it. There is also a rubber gasket that is a part of the notches and helps create an airtight seal after inserting your portafilter into the machine. The notches on the head allow for a precise positioning of the portafilter which is essential for an efficient extraction.
The group head not only allows you to place your portafilter easily but also maintains the same temperature. It does this by circulating hot water through the brew basket and around the portafilter, ensuring that it is always at the correct temperature for extraction. It is important to realize that even a slight differences can make the distinction between a good and great pro espresso machine.
The Pump
In contrast to manual piston machines that use a lever to pressurize water, Rotary cafe espresso machine machines rely on motorized pumps to supply the nine atmospheric bars of pressure that are required for professional espresso machine for home extraction. The pressure is created by drawing tap water from a reservoir and pumping it through a heat exchanger before being pumped through the ground coffee in the group head.
Pumps are typically less expensive and last longer than piston-driven machines. However, both kinds of machines can degrade due to excessive use and inadequate cleaning. Pumps are also more complex mechanically, which can increase the cost of even most basic models.
Some espresso machines can eliminate the pump entirely and make use of steam pressure to make espresso. This can cause over-extraction because the boiler that makes steam also causes the water to boil. These machines also have to continuously rebuild their pressure between cups. This requires energy and time.
Many espresso machines make use of the rotary or vibration pump, with a vibrating model using a vibrating disc to create pressure and rotating models that push hot water through the grounds at high speed. Both types of machine can make a great espresso maker barista, Cafe Espresso machine but the rotary pumps are quieter, and more durable than vibration pumps.
The Boiler
The boiler will heat the water to the right temperature for extraction. The resultant steam then reaches the portafilter, which contains ground espresso beans and is then pumped into the cup. During this process the steam generates enough pressure to push the grounds of coffee through. This results in a layer of crema on top. This is one of the main characteristics of a great espresso.
There are three types of espresso machines, each with different types of pumps and the temperature of the brew. There are a variety of ways that the brew can be controlled, as well as the dimensions of the cup the machine can make.
The first espresso machines were steam-types. They employed only one boiler to make steam and brew, however the pressure they were able to produce was very low - just two bars of atmospheric pressure at the most. This led to the coffee tasting bitter and burnt. The modern espresso machine was designed by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most popular espresso machine is a semiautomatic that has an electric pump. When people think of espresso machines, they think of these machines. With a semi-automatic machine you grind the beans and then tamp them yourself but the pump is able to regulate the flow of water and pressure. This is a fantastic compromise between human control and mechanized reliability.
The Filter
Espresso machines typically use filters that separate the grounds of the coffee from the hot water. The filter is also an essential part of the temperature control system, as it keeps the machine from overheating.
A filter also helps with flavor as it allows for a longer flowering phase. This allows the beans to release their flavor and improves extraction.
However, it is important to keep in mind that even a good filter can make a terrible cup of coffee, since the quality of the beans and extraction is crucial.
It's in this area that the magic happens. This is what makes espresso taste so delicious. The grouphead (also known as the brewhead) is where you put the portafilter, which is the thingy which you put the coffee grounds into, when making espresso coffee machine.
Steam-driven espresso machines make use of hot water that is heated in an airtight container to create steam. The steam then pushes hot water through grounds of coffee under high pressure. These types of machines are generally less expensive and simpler to maintain than pumps-driven models. They are however limited in their ability for cafe Espresso Machine creating the ideal conditions for brewing, as they operate with 1-1.5 bar of pressure. The perfect shot requires 9-10 bars.
In recent years, compressed air-driven espresso machines have become more popular. They use an air-compressor to push hot water through the ground, and are more mobile than steam-driven electric espresso machines.
