How Does Machine Espresso Work?
The machine espresso uses precision pressure, and a filtering technology that is amazing to create the coffee you love. What exactly does it work?
Espresso is made by pushing hot water at high pressure through finely ground coffee. The process is similar to making drip coffee, but the major difference is in the pressure.
The Head of the Group
As the name implies the group head is the place you place your portafilter when brewing espresso. It disperses the water into the portafilter, and regulates the pressure of the extraction. There are a variety of group heads, each with its own advantages and disadvantages. Some are specifically designed for stability in temperature, while others are specifically designed to handle pre-infusion. Some are designed to control the lever. There are some that come with a range of features, like the E61 that is the most popular choice among baristas due to its ability to offer multiple benefits in one package.
As you can see in the image above the group head is fitted with several notches. The portafilter is placed into these notches and turn the head around to secure it. A gasket made of rubber is placed within the notches to create a seal when you insert your portafilter. The notches permit precise placement of your portafilter. This is crucial for a consistent extraction.
The group head is not just able to allow the portafilter to be inserted easily however it also keeps the temperature at a constant level. This is achieved by cycling hot water around the portafilter, and through the brew-basket to ensure the temperature is always right to extract the coffee. This is crucial, since just a few degrees could mean the difference between excellent and great espresso machines for home.
The Pump
The motorized pumps used in rotary espresso machines supply the nine atmospheric bar pressure that is required for espresso extraction. This differs from manual piston machines which use a lever. The pressure is created by pumping water through a heat exchanger and then through the ground coffee.
Pumps tend to be cheaper and last longer than piston-driven machines. However, both kinds of machines may degrade because of excessive use and inadequate cleaning. They also increase the complexity of mechanical systems, which can result in an expensive price for even the simplest models.
Some espresso machines employ steam pressure instead of a pump to brew italian espresso machines. The disadvantage of this is that the boiler that produces steam also raises the temperature of the water until it reaches boiling which can cause over-extraction. Additionally, these machines frequently have to restore their pressure between cups, which takes time and energy.
A majority of espresso machines utilize either a vibration or rotary pump. A vibration model employs a vibrating disk to generate pressure, while the rotary model pushes hot water through the ground at a rapid speed. Both types of machines can make a great espresso, however the rotary models are quieter and more durable than vibration pumps.
The Boiler
The boiler is what will heat the water to the right temperature for extraction. The steam produced will eventually reach the portafilter, which contains the espresso coffee grounds. It is then poured into the cup. The steam causes pressure to push through the coffee grounds. This produces a layer of crema that is then poured over. This is a hallmark of a good espresso coffee machine for home.
There are three different types of espresso machines, each having different pumps and the temperature of the brew. There are various ways in which the brew could be controlled and the dimensions of the cup the maker can create.
The first espresso machine uk machines were steam-type. They had one boiler to create both steam and brew, but the pressure they could generate was low - only two bars of atmospheric pressure at the most. This resulted in 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 one with an electric pump. When people think of espresso machines for home machines, they imagine these machines. With a semi-automatic espresso machine, you grind the beans and then tamp them by hand, but the pump is able to regulate the flow of water and pressure. This is an excellent compromise between human touch and the mechanised consistency.
The Filter
Espresso machines usually use a filter that separates the coffee grounds from the hot water. The filter is also an essential component of the machine's temp control, as it prevents overheating.
A filter can also help with flavor, as it permits a longer flowering period. This allows the beans to release their nuances, and allows for better extraction.
However, it is important to keep in mind that even a top filter can produce a bad cup of coffee as the quality of the beans and extraction is still crucial.
It's here that the magic occurs. This is what makes espresso taste so delicious. The grouphead, also referred to as the brew head, is where the portafilter (the thing you put the ground coffee into) is placed when making espresso.
Steam-driven espresso machines use hot water that is heated inside an airtight container to make steam. The steam then pushes hot water through grounds of coffee under high pressure. These machines are less expensive and easier to maintain than pumps-driven models. However, they are limited in their ability to produce the perfect conditions for brewing, since they operate at 1-1.5 bars of pressure, while the perfect shot requires 9-10 bar.
In recent years, compressed air-driven espresso machines have been gaining popularity. They use an air compressor to push hot water through the grounds and are more portable than electric steam-driven machines.
