How Does Machine Espresso Work?
Machine espresso employs precise pressure and amazing filter technology to make the coffee we love. But how exactly does it work?
Espresso is made by forcing hot water under high pressure through finely-ground coffee. The process is similar to making drip coffee, but the difference is in the pressure.
The Group Head
The name implies, the group head is where you put your portafilter in when making espresso. It is responsible for dispersing the water into the portafilter and then controlling the pressure of the resulting extraction. There are a variety of group heads each with their own advantages and drawbacks. Some are focused on temperature stability, whereas others on pre-infusion features, and others are designed to control the lever. There are some that come with a range of features, such as the E61, which is to be the most popular among baristas because of its ability to provide multiple benefits in one package.
As you can see in the above image The group head features several notches where you place your portafilter and twist it by hand to lock it in. A gasket of rubber is situated inside the notches, which helps create a seal as you insert your portafilter. The notches on the head allow for an exact location of the portafilter which is vital to ensure an efficient extraction.
The group head not only lets you to insert your portafilter easily but also maintains the temperature at a constant level. It does this by circulating hot water through the brew pan and around the portafilter to ensure that it's always at the correct temperature for extraction. It is important to remember that even a small difference can make the difference between a great and a excellent espresso.
The Pump
The motorized pumps in espresso machines rotary provide nine atmospheric bar pressure that is required to extract espresso. This differs from manual piston machines that use levers. The pressure builds by removing tap water from a reservoir and pumping it through a heat exchanger before being pumped through the ground coffee in the group head.
Pumps tend to be cheaper than piston-driven models, and they tend to last longer. However, both types of machines could get damaged through overuse and lack of cleaning. Pumps are also more complex mechanically, and can add to the price of even the most basic models.
Certain espresso machines utilize steam pressure instead of a pump to brew espresso. This can cause over-extraction because the boiler that produces steam also warms the water to boil. The machines must also continually rebuild their pressure between cups. This takes energy and time.
A majority of espresso machines utilize an rotary or a vibration pump. A vibration model makes use of a rotating disk to generate pressure, whereas a circular model pushes hot liquid through the ground at high speed. Both types of machine can make excellent italian espresso machine, however Rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is the element which heats the water to the optimal temperature to extract. The resultant steam then reaches the portafilter that contains the ground espresso and filter coffee machine (instituto.disitec.pe) best coffee espresso machine and gets funnelled down into the cup. The steam is able to create enough pressure to push the grounds of the coffee through. This produces a layer of crema on top. This is one of the main characteristics of a good espresso.
There are three types of espresso makers, which differ in the type of pump they use and how hot the mini espresso maker is. There are also different ways in which the brew can be controlled as well as the size of the cup that the machine can make.
The first espresso machines were steam-type. They used one boiler to make both steam and brew however the pressure they were able to produce was very low - just two bars of atmospheric pressure maximum. This led to the coffee tasting burnt and bitter. The modern espresso machine was developed by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most well-known espresso machine is a semiautomatic that has an electric pump. This is what people envision when they think of an espresso machine. Semi-automatic machines require you to grind and tamp your beans yourself however the pump controls the flow of water and pressure. This is an excellent compromise between human control and mechanised consistency.
The Filter
Espresso machines typically have a filter that separates the grounds of the coffee from the hot water. The filter is also a vital element of the temperature control system, as it prevents the machine from overheating.
It also aids in flavor, as a filter allows for a more prolonged bloom phase. This allows beans to release their flavor and gives an opportunity for a better extraction.
However it is crucial to keep in mind that even a good filter can produce a bad cup of coffee, as the quality of the beans and extraction is essential.
This is where the magic happens, it's what makes espresso taste good. The grouphead (also known as the brewhead) is where you put the portafilter, which is the thingy used to place the grounds of your coffee into when making espresso.
Steam-driven espresso machines make use of hot water heated in an airtight container to make steam. The steam then pushes hot water into the grounds of the coffee under pressure. They are less expensive and easier to maintain than pumps-driven models. However, they are limited in their capacity to create the perfect brewing conditions as they only operate at 1-1.5 bars of pressure, while the perfect shot requires 9-10 bar.
In recent years, compressed air-pump-driven espresso machines have become more popular. They utilize an air compressor to push hot water across the ground and are much more mobile than steam-driven electric espresso machines.
