How Does Machine Espresso Work?
The machine espresso uses precision pressure, and filtering system that is awe-inspiring to make the coffee you love. How exactly does it work?
Espresso is created by forcing hot water under pressure through finely ground coffee. The process is similar to making drip coffee, but the key difference is in the pressure.
The Group Head
As the name suggests, the group head is where you insert your portafilter when making espresso. It disperses the water into the portafilter, and then regulates the pressure of extraction. There are various kinds of group head, each with their own advantages and disadvantages. Some are focused on temperature stability, while others on pre-infusion capabilities, and still others are designed to control the lever. There are even some that have a combination of features, such as the E61 one, which is the classic choice among many baristas because of its ability to provide multiple benefits in one package.
As you can see in the image above the group head is made up of several notches to place your portafilter and twist it by hand to secure it. A rubber gasket is located inside the notches, which helps create a seal as you insert your portafilter. The notches on the head allow for an exact placement of the portafilter, which is necessary for an even extraction.
Apart from allowing you easily place your portafilter in, the group head is also responsible for maintaining an even 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 tiny variation can mean the difference between a great and a excellent espresso.
The Pump
The motorized pumps used in rotary espresso machines provide the nine atmospheric bar pressure that is required to extract espresso. This differs from manual piston machines that use a lever. The pressure is created by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be more affordable and last longer than piston-driven machines. However, both types of machines are susceptible to degrading because of frequent use and inadequate cleaning. They also increase the complexity of mechanical systems and can lead to the cost of even the simplest models.
Some espresso machines use steam pressure instead of a pump in order to brew espresso. This can result in over-extraction because the dual boiler espresso machine that produces steam also causes the water to boil. These machines also have to constantly 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 that uses a vibrating disc to create pressure, and the rotary model pushing hot water through the grounds at high speed. Both machines can produce excellent espresso however rotary machines tend to be quieter, more durable and less likely to break.
The Boiler
The boiler is the part that heats water to the optimal temperature for extraction. The steam that is produced is then directed to the portafilter, which is the container that holds the espresso coffee grounds. It is then pumped into the cup. During this process, the steam creates pressure to push through the coffee grounds. This creates a crema on top of the espresso. This is one of the hallmarks of a good espresso.
There are three types of espresso machines, each with a different type of pump and brew temperature. There are many ways to control the brew as well as the size of cup that can be made by the machine.
The first espresso machines were steam-type. The first espresso machines were steam-type machines. This led to the coffee tasting bitter and burnt. The modern espresso machines home machine was designed by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most well-known espresso maker is a semi-automatic device with an electric pump. When people think of espresso machines, they picture these machines. Semi-automatic machines require you to grind and tamp the beans on your own, but the pump regulates the flow of water and pressure. This is an excellent compromise between human control and mechanised accuracy.
The Filter
Typically, espresso machines have filters to separate the grounds of the coffee as they go through the hot water. The filter is also a crucial component of the temperature control system, because it stops the machine from overheating.
It also aids in flavor as a filter can allow for a longer bloom phase. This lets the beans release their flavor and allows for a better extraction.
It is important to remember that even the finest filter can make a bad cup of coffee. The quality of the beans and the extraction process are still very important.
It's in this area that the magic happens. This is the reason why espresso tastes so good. The grouphead, also referred to as the brew head, is the place where the portafilter (the thingy you put the ground coffee in) is placed when you're making espresso.
In the steam-driven espresso machine hot water is heated in an airtight container to create steam. This then pushes the hot water through the grounds at a high pressure. These machines are less expensive and easier for the owner to maintain than pumps-driven models. They are however limited to create the perfect conditions for brewing since they only operate with 1-1.5 bar of pressure. The perfect shot requires 9-10 bars.
In recent times, espresso machines powered by a compressed air compressor have become increasingly popular. They utilize an air compressor to push hot water into the grounds and are more portable than steam-driven electric machines.
