How Does Machine Espresso Work?
The machine espresso is made using precise pressure, as well as a filtering technology that is amazing to make the coffee you love. How exactly does it work?
In order to make espresso, hot water is pushed under pressure through finely ground coffee. The process is similar to making drip coffee espresso machine, however the main difference lies in the pressure.
The Group Head
As the name suggests the group head is the place you put your portafilter in when making espresso. It disperses water into the portafilter, and regulates the pressure during the extraction. There are numerous kinds of group heads each with their own advantages and drawbacks. Some focus on temperature stability, while others on pre-infusion features, and others are designed to control the lever. Some come with a combination of both, like the E61. This is a favorite among baristas because it offers multiple advantages in a single package.
As you can see from the photo above the group head has a number of notches. The portafilter is placed in these notches, then turn the head around to secure it. A gasket of rubber is situated in the notches to create a seal as you insert your portafilter. The notches permit an exact placement of the portafilter. This is crucial to ensure an even extraction.
The group head not only allows the portafilter to be inserted easily however it also keeps a constant temperature. This is done by cycling hot water around the portafilter and through the brew-basket, ensuring that the temperature is at the right level to extract the coffee. It is important to remember that even a few degree deviation can make the difference between a decent and a excellent espresso.
The Pump
Unlike manual piston machines, which use a lever to pressurize water, the rotary uk compact espresso machine machine - Continue Reading - machines use motorized pumps to supply the nine atmospheric bars of pressure that are required to extract espresso. The pressure is created by drawing tap water from a reservoir, espresso coffee Machines uk and pumping it through a heat exchanger prior to being shot through the ground coffee inside the group head.
Pumps are generally less expensive than piston-driven models, and they tend to last longer, however both types of machines can get damaged through overuse and lack of cleaning. Pumps are also more complex mechanically, which can increase the cost of even most basic models.
Certain espresso machines can eliminate the pump completely and utilize steam pressure to make espresso. The downside is that the boiler that produces steam also raises the temperature of the water to the point of boiling which could lead to over-extraction. The machines also need to constantly rebuild their pressure between cups. This takes energy and time.
Many espresso machines make use of an rotary or a vibration pump. A vibration model utilizes a vibrating disk to generate pressure, whereas the rotating model pushes hot water through the ground at a fast speed. Both machines can produce excellent professional espresso machine, but rotary machines are quieter, more durable and less likely to fail.
The Boiler
The boiler is the part which heats the water to the optimal temperature to extract. The steam that is produced reaches the portafilter which holds the ground espresso and is then funneled down into the cup. The steam causes enough pressure to push the grounds of the coffee through. This results in a whipped-up the top of the espresso. This is a sign of a good espresso.
There are three distinct types of espresso machines, each with a different type of pump and the temperature of the brew. There are a variety of ways to control the amount of brew, as well as the size of the cup that can be produced by the machine.
The first espresso machines were steam type. They employed one boiler to make both steam and brew however, the pressure they could produce was not very high - two bars of atmospheric pressure at most. This resulted in the coffee tasting bitter and burnt. The modern espresso machine was designed by the Milanese producers Luigi Bezzerra & Desiderio Pavoni.
The most well-known espresso maker is a semi-automatic one with an electric pump. When people think of espresso machines, they think of these machines. If you have a semi-automatic machine you need to grind the beans and then tamp them by hand. However, the pump regulates the flow of water and pressure. This is a fantastic combination of human control and mechanized reliability.
The Filter
Espresso machines typically have a filter that separates the grounds of coffee from hot water. The filter is also a vital part of the machine's temperature control, as it helps prevent overheating.
It also aids in flavor, as it lets you enjoy a longer bloom time. This allows beans to release their nuances and gives an opportunity for better extraction.
It is important to keep in mind that even the best espresso machine filter can make a bad cup of coffee. The quality of the beans, and the extraction process, are still crucial.
It's in this area that the magic occurs. This is the reason why espresso tastes so delicious. The grouphead, often referred to as the brew head, is where the portafilter (the thingy you put the ground coffee in) is placed when you're making espresso.
Steam-driven espresso machines use hot water that is heated in an airtight container to create steam. The steam then pushes hot water through coffee grounds under high pressure. These types of machines are typically less expensive and simpler to maintain than pumps-driven models. They are however limited to create the ideal conditions for brewing, as they operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent times, espresso machines powered by a compressed air compressor have become increasingly popular. They use an air compressor to force hot water through the grounds and are significantly more portable than electric steam-driven machines.
