How Does Machine Espresso Work?
The machine espresso makes use of precise pressure and filter technology that is awe-inspiring to make the coffee you love. How does it work exactly?
To make an espresso, hot water is pushed under pressure through finely ground coffee. The process is similar to making drip coffee. However the pressure is the main difference.
The Group Head
As the name implies the group head is the place you place your portafilter while brewing espresso. It is responsible for dispersing water into the portafilter before controlling the pressure of the extraction. There are many different types of group heads each with distinct advantages and drawbacks. Some are focused on temperature stability, whereas others on pre-infusion capabilities, while others are designed to control the lever. Some come with a combination of both, like the E61. This is a preferred choice for baristas due to the fact that it has multiple advantages in one package.
As you can see in the image above the group head is fitted with a variety of notches. You can place your portafilter in these notches, then turn the head around to secure it. There is also a rubber gasket that is a part of the notches to help create an airtight seal when you insert your portafilter into the machine. The notches permit precise placement of your portafilter. This is crucial for an efficient extraction.
Apart from allowing you easily connect your portafilter, the group head is responsible for maintaining a consistent temperature. It does this by cycling hot water through the brew basket, and around the portafilter, espresso Makers making sure that it is always at the correct temperature to extract. It is crucial to keep in mind that even a slight differences can make the distinction between a decent and a excellent espresso.
The Pump
The motorized pumps used in rotary espresso machines supply the nine atmospheric bar pressure needed for espresso extraction. This is different from manually operated piston machines that employ levers. This pressure is built up by pumping water through a heat exchanger and then through the ground coffee.
Pumps are typically cheaper and last longer than piston-driven machines. However, both types of machines are susceptible to degrading due to excessive use and insufficient cleaning. Pumps are also more complex mechanically, which can increase the cost of even the simpler models.
Some espresso machines make use of steam pressure instead of a pump to make espresso. This can cause over-extraction because the boiler that makes steam also heats the water to boil. They also have to continuously rebuild their pressure between cups. This takes energy and time.
Many espresso machines make use of the rotary or vibration pump. A vibration model makes use of an oscillating disk to create pressure, while the circular model pushes hot liquid through the ground at a high speed. Both types of machines can make a great espresso, but Rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is the one that is used to heat the water to the ideal temperature for extraction. The steam created will eventually reach the portafilter, which is the container that holds the espresso coffee grounds. It is then poured into the cup. During this process the steam is able to create enough pressure to push the grounds of the coffee through. This results in a layer of crema that is then poured over. This is a sign of a great espresso.
There are three kinds of espresso makers, and they differ in the kind of pump they use and the degree of heat that the coffee is. There are different ways in which the brew can be controlled as well as the size of the cup that the machine can produce.
The earliest espresso machine small machines were steam type. They had one boiler to create both steam and brew but the pressure they could produce was very low - just two bars of atmospheric pressure, at most. The coffee for espresso machine tasted bitter and burnt. The modern espresso machine was designed by the Milanese manufacturers Luigi Bezzerra & Desiderio Pavoni.
The most common espresso machine is a semiautomatic one with an electric pump. These are the images people have when they imagine an espresso machine. Semi-automatic machines require you to grind and tamp the beans by yourself, but the pump regulates the water flow and pressure. This is an excellent compromise between human touch and the mechanized quality.
The Filter
Typically, espresso coffee maker machines have a filter to separate out the grounds of the coffee as they go through the hot water. The filter is also an essential element of the temperature control system as it keeps the machine from overheating.
It also enhances flavor, since a filter allows for a more prolonged bloom time. This allows beans to let their nuances out and provides an opportunity for better extraction.
It is important to keep in mind that even the finest filter can result in a bad cup of coffee. The quality of the beans, and the extraction, remain crucial.
This is where the magic happens, it's what makes an espresso really taste great. The grouphead, espresso makers sometimes referred to as the brew head, is where the portafilter (the thingy you put the ground coffee in) is located when you're making espresso.
Steam-driven espresso machines use hot water that is heated inside an airtight container to produce steam. The steam then pushes hot water into the grounds of the coffee under pressure. These kinds of machines are typically cheaper and easier to maintain than pump-driven models. They are however limited to create the perfect conditions for brewing as they only operate with 1-1.5 bar of pressure. The perfect shot requires 9 bar espresso machine-10 bars.
In recent years, compressed-air-pump-driven espresso machines have been gaining popularity. They utilize an air compressor to force hot water into the grounds, and are far more portable than steam-driven electric machines.
