How Does Machine Espresso Work?
The machine espresso uses precision pressure, and filtering technology that is amazing 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, however the main difference lies in the pressure.
The Group Head
As the name suggests, the group head is where you insert your portafilter when making espresso. It is responsible for dispersing water into the portafilter before controlling the pressure of the extraction. There are a variety of types of group head, each with their unique advantages and drawbacks. Some are designed for stability in temperature, while others are built to handle pre-infusion. Others are made to control the lever. Some come with a combination of both, like the E61. This is a very popular choice for baristas since it provides multiple advantages in one package.
As you can see in the image above The group head features many notches in which you can place your portafilter before twisting it by hand to lock it in. There is also a rubber gasket that is a part of the notches, which helps create the seal when you insert your portafilter into the machine. The notches permit precise placement of your portafilter. This is crucial for an efficient extraction.
The group head does not just allow you to insert your portafilter 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 constant for extraction. This is important, as even a small difference in temperature can make the difference between a excellent and great espresso.
The Pump
The motorized pumps in espresso machines rotary provide nine atmospheric bars of pressure required for espresso extraction. This is different from manual piston machines that use a lever. This pressure is generated 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 kinds of machines espresso are susceptible to degrading because of excessive use and poor cleaning. Pumps are also more complex mechanically, which can increase the cost of even simpler models.
Some espresso machines use steam pressure instead of a pump to make espresso coffee machine for home. This can result in over-extraction because the boiler that makes steam also heats the water to boil. Additionally the machines often have to rebuild their pressure between cups, which requires time and energy.
Many espresso machines employ the rotary or vibration pump, with a vibration model using a vibrating disc to generate the pressure, and a rotary model pushing hot water through the grounds under high speed. Both machines can produce excellent espresso but rotary machines are more stable, quieter and less likely to break.
The Boiler
The boiler is the component that heats water to an ideal temperature for extraction. The steam that is produced gets to the portafilter which contains the espresso coffee grounds. It is then poured into the cup. The steam generates enough pressure to push the coffee grounds through. This creates a layer crema that is then poured over. This is one of the hallmarks of a good espresso.
There are three kinds of espresso makers, which differ in the kind of pump they use and the degree of heat that the espresso is. There are various ways to control the amount of brew, as well as the size of cup that can be made by the machine.
The first espresso machines were steam type. The earliest espresso machines were steam-type machines. The coffee tasted bitter and burned. The modern espresso machine was designed by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most common espresso maker is a semi-automatic machine with an electric pump. When people think of Buy Espresso Machines machines, they imagine these machines. Semi-automatic machines require you to grind and tamp the beans yourself however the pump controls the water flow and pressure. This is a great compromise between the human touch and the mechanised consistency.
The Filter
Espresso machines usually have filters that separate the coffee grounds from the hot water. The filter is also a crucial element of the temperature control system, since it helps prevent the machine from overheating.
It also aids in flavor, as it allows for a longer bloom phase. This helps the beans to release their flavors and provides an opportunity to improve extraction.
However it is crucial to keep in mind that even a top filter can result in a poor cup of coffee espresso machines, as the quality of the beans and extraction is still crucial.
This is where the magic happens, it's what makes espresso taste great. The grouphead (also called the brewhead) is where you put the portafilter - the thingy used to place the grounds of your coffee into when making espresso.
In the steam-driven espresso machine hot water is heated in an airtight tank to create steam. Steam is then pushed through the grounds with high pressure. These types of machines are usually less expensive and easier to maintain than pump-driven models. They are however limited to create the ideal brewing conditions as they only operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, compressed air-driven espresso machines have been gaining popularity. They make use of an air compressor to push hot water through the ground and are much more mobile than steam-driven electric espresso machines.
