How Does machine espresso (okerclub.ru) Work?
Machine espresso employs precise pressure and incredible filter technology to produce the delicious coffee we enjoy. How does it work exactly?
Espresso is made by pushing hot water under pressure through finely ground coffee. The process is similar to making drip coffee, however the main difference lies in the pressure.
The Group Head
The group head is the portafilter is inserted when you are making espresso. It disperses water into the portafilter, and regulates the pressure of extraction. There are many different kinds of group head, each with their own advantages and disadvantages. Some are designed to provide 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, such as the E61. This is a very popular choice for baristas as it provides a variety of benefits in a single package.
As you can see in the image above The group head features several notches to place your portafilter before twisting it by hand to secure it. A gasket made of rubber is positioned inside the notches to help make a seal when you insert your portafilter. The notches on the head permit an exact location of the portafilter which is necessary for a consistent extraction.
Apart from allowing you effortlessly insert your portafilter the group head is also responsible for maintaining a consistent temperature. It does this by circulating hot water through the brew basket and around the portafilter to ensure that it's always at the correct temperature for extraction. This is crucial, since even a small difference in temperature can make the difference between a good and excellent espresso.
The Pump
The motorized pumps in rotary espresso machines provide the nine atmospheric bar pressure needed to extract espresso. This is different from manual piston machines that use a lever. The pressure is created by drawing tap water from a reservoir, and pumping it through a heat exchanger prior being pumped through the ground coffee inside the group head.
Pumps are generally cheaper and last longer than piston-driven machines. However, both types of machines may degrade because of frequent use and insufficient cleaning. Pumps are also more complicated mechanically, which could increase the price of even the most basic models.
Certain espresso machines do away with the pump entirely and use steam pressure to brew espresso. This could lead to over-extraction since the boiler that makes steam also causes the water to boil. They also have to constantly rebuild their pressure in between cups. This takes energy and time.
Many espresso coffee makers machines use a rotary or vibration pump. A vibration model utilizes the vibrating disk bean to cup espresso machine create pressure, while the rotary model pushes hot water through the ground at a fast speed. Both types of machine can produce an excellent espresso, but rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is what will heat the water to a temperature that is ideal to extract. The resulting steam is then transferred to the portafilter that contains ground espresso beans and is then pumped into the cup. During this process, the steam creates pressure to push through the grounds of the coffee. This creates a layer crema on top. This is the hallmark of a great espresso.
There are three types of espresso machines, each with different types of pumps and brew temperature. There are different ways in which the brew can be controlled and the size of the cup that the machine can make.
The first best espresso machine machines were steam-type. The earliest espresso machines were steam types. The coffee tasted bitter and burnt. The modern espresso machine was invented by the Milanese producers Luigi Bezzerra & Desiderio Pavoni.
The most common espresso maker is a semi-automatic machine that has an electric pump. When people think of espresso machines, they imagine these machines. Semi-automatic machines require you to grind and tamp the beans by yourself while the pump controls the flow of water and pressure. This is a great compromise between human control and mechanised reliability.
The Filter
Typically, espresso machines employ a filter to separate out the grounds of coffee when they pass through the hot water. The filter is also an essential component of the temperature control system, as it keeps the machine from overheating.
It also helps with flavor as a filter allows for a more prolonged bloom time. This allows beans to release their flavors and provides an opportunity for better extraction.
However, it is important to keep in mind that even a great 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 takes place. 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 coffee grounds into) is located when you're making espresso.
Steam-driven espresso machines use hot water that is heated in an airtight container to make steam. The steam then moves hot water through the coffee grounds under high pressure. These types of machines are typically cheaper and easier to maintain than pump-driven models. However, they are limited in their ability to create the perfect brewing conditions since they 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 use an air compressor to push hot water into the grounds and are more portable than electric steam-driven machines.
