How Does Machine Espresso Work?
The machine retro espresso maker makes use of precision pressure, and filter technology that is awe-inspiring to make the coffee you enjoy. How does it work exactly?
In order to make espresso, hot water is forced under high pressure through finely ground coffee. The process is similar to making drip coffee but the key difference is in the pressure.
The Group Head
The group head is the portafilter you place in the espresso maker when making it. It is responsible for dispersing the water into the portafilter before controlling the pressure of the extraction. There are many different types of group heads each with distinct advantages and disadvantages. Some are focused on temperature stability, whereas others on pre-infusion features, and others are designed to control the lever. There are some that contain a variety of features, such as the E61 that is the standard choice for many baristas due to its capacity to offer multiple benefits in a single package.
As you can see in the photo above, the group head has several notches where you place your portafilter before twisting it by hand to secure it. A gasket made of rubber is positioned within the notches to create a seal while you insert your portafilter. The notches on the head permit an exact position of the portafilter which is necessary for an efficient extraction.
The group head not only allows you to insert your portafilter easily, but it also maintains a constant temperature. It does this by cycling hot water through the brew pan and around the portafilter, making sure that it is always at the right temperature to extract. It is important to note that even a small difference can make the difference between a decent espresso machine and a excellent espresso.
The Pump
Unlike manual piston machines, which rely on a lever that pressurize water, the rotary espresso machines use motorized pumps that provide the nine atmospheric bars of pressure that are required to extract espresso. The pressure builds by removing tap water from a reservoir and pumping it through a heat exchanger prior to being shot through the ground coffee inside the group head.
Pumps tend to be less expensive than piston-driven machines, and they tend to last longer, but both types of machines could be damaged by excessive use and inadequate cleaning. Pumps are also more complicated mechanically, which can raise prices of even simplest models.
Certain espresso machines utilize steam pressure instead of a pump to make espresso. This can result in over-extraction because the boiler that produces steam also heats the water to boil. These machines also have to continually rebuild their pressure between cups. This takes energy and time.
Many espresso machines make use of either a rotary or vibration pump, which has a vibration model that uses a vibrating disc that generates the pressure, and an rotary model that pushes hot water through the grounds under high speed. Both types of machine can make a great espresso machine coffee, but the rotary models are quieter and more durable than vibration pumps.
The Boiler
The boiler is the one that makes the water warm to the ideal temperature for extraction. The steam produced gets to the portafilter which is a container for compact espresso machine grounds. It is then pumped into the cup. During this process, steam creates pressure and pushes through the coffee grounds. This produces a layer of crema that is then poured over. This is the hallmark of a good espresso.
There are three kinds of espresso makers, and they differ in the type of pump they employ and how hot the espresso is. There are a variety of ways that the brew can be controlled as well as the size of the cup that the maker can create.
The first espresso machines were steam type. They had a single boiler to make steam and brew, however, the pressure they could create was minimal - two bars of atmospheric pressure maximum. The coffee tasted bitter and burnt. This is the reason why Milanese manufacturers Luigi Bezzerra and Desiderio Pavoni invented the modern espresso machine.
The most commonly used espresso maker is a semi-automatic machine with an electric pump. These are the images people have when they think of an espresso maker. With a semi-automatic espresso machine, you need to grind the beans and tamp them by hand. The pump is able to regulate the flow of water and pressure. This is an excellent compromise between human touch and the mechanised accuracy.
The Filter
best budget espresso machine machines typically use a filter that separates the grounds of the coffee from hot water. The filter is also a vital element of the temperature control system, since it helps prevent the machine from overheating.
Filters also aid in flavor since it allows for a longer flowering period. This allows the beans to release their flavors, and also allows for better extraction.
However, it is important to remember that even a great filter could result in a bad cup of coffee as the quality of the beans and extraction is still crucial.
It's in this area that the magic occurs. This is what makes espresso taste so good. The grouphead, sometimes referred to as the brewhead, is where the portafilter (the thingy you put the ground coffee in) sits when you're making espresso.
Steam-driven espresso machines make use of hot water that is heated in an airtight vessel to create steam. The steam then moves hot water through the grounds of the coffee under pressure. These types of machines tend to be cheaper and easier to maintain than pump-driven models. However, they are not as efficient in their ability to provide the perfect conditions for brewing, because they operate at 1-1.5 bars of pressure. The perfect shot requires 9-10 bar.
In recent times, espresso coffee maker machines powered by a compressed air pump have become increasingly popular. They utilize an air compressor to push hot water through the grounds and are more portable than electric steam-driven machines.
