Important Parts of an Espresso Machine
A quality espresso machine must give a rich and strong shot of coffee, with a full aroma and a strong flavor. This requires a high level of pressure and temperature.
Also, pay attention to the crema, which is a golden brown layer that gives the espresso its characteristic flavor and color. There are four types of espresso machines. These include semi-automatic, manual and automatic.
Water reservoir
The reservoir for water is a container that houses chilled, purified water that is fed into the espresso machine. It is usually removable and comes with a lid to keep the water fresh and free of dust. It is an important part of an espresso machine, and should be kept clean to prevent clogging. To clean it, you can pour vinegar into the reservoir and let it run for about a minute.
The espresso machine utilizes water to pressurize coffee grounds and extract the flavors, oils and caffeine. It also produces crema, the foam. Achille Gaggia designed the first espresso machines, which utilized pistons and levers to create high-pressure making. Gaggia's spring piston levers were used to push water through the coffee into the cup. This created a brand new term "coffee crème" (crema).
The pump is an electric device that moves the water through the heating element to bring it up to the ideal brewing temperature of 195 degrees Fahrenheit. It is usually situated at the bottom of the machine and attached to a tube which runs up to the heating element. The tube is also connected at either end to hot-water and cold-water tubes. It also passes underneath the heating elements of resistance which are covered with white grease to keep the plate warm.
Pump
The pump is what makes an espresso machines work and there are many types. Some machines use a vibratory pump or a vibratory pump that uses an electromagnetic motor to move between the sides of a coil at 60 pushes per sec. The pump then pumps water through the portafilter and out of the spouts. Other pumps employ the heating system known as a thermoblock or thermocoil, which heats the water precisely at the temperature that is required for the brewing. These systems also allow for the control of water pressure and temperature, which is important to ensure a good extraction.
Pump-driven espresso machines could employ a spring, piston or electric pump. However, they all require that water be moved through the grounds of the coffee with high pressure. The higher the pressure, the more delicious the extraction. The pump makes sure that the coffee ground is evenly distributed, which helps create a great crema.
Other types of espresso machines include piston-driven or steam-driven. In a steam-driven machine the water is forced through the coffee using steam pressure. This type of espresso machine is more affordable, but does not generate as much pressure for extraction. There are also air pump-driven espresso machines that are smaller, lighter and do not require a steam boiler. They can be powered by a hand-pump or a canister using compressed air (such N2 or CO2). Air-pump espresso makers yield less espresso when compared to pumps-driven machines, but can be more convenient for some people.
Steam tool
The steam wand is a thin metal pipe that comes out of the espresso maker and releases steam that is hot and pressurized into the milk to create foamy drinks like cappuccinos or lattes. You can also make hot water for cocoa or tea. The wand is equipped with several holes that can be turned on or off to control the amount of steam released. Some machines have the traditional wand while others have a Pannarello, which is easier to use but does not produce foam suitable for latte arts.
If you're having difficulty getting your milk to froth, you might be having a problem with your espresso machine's anti-vacuum valve. This valve is designed in order to prevent air from getting into the steam wand when it is in use. You can test it by lower the steam wand and watching for a whirring sound. If you hear this sound it indicates coffee espresso machine that air is being sucked into the wand and you need to raise the wand so that it is submerged more fully.
You can also test the anti-vacuum by taking off the wand and washing it with warm water using a soft bristled sponge or brush. It is important to keep the wand clean to prevent clogs, which can impact your foaming. If you're not able to fix it on your own, call a professional or the manufacturer.
Control panel
The control panel enables users to alter and set up settings. These include coffee strength as well as milk volume. These settings are stored in memory and can be modified anytime. The display indicates when the machine needs to be descaled and whether the reservoir of water is full.
The majority of espresso machines have hot water dispensers. This is usually located close to or between groups. It can be used to make hot cups or tea, in the event of need. It's also great for cleaning and rinsing. Many models have pressure gauges that indicate the current pressure of the boiler.
A brew switch is also available, which controls the brew process as well as the amount of shots. This is important since espresso shot size is determined by the length of time that the grounds are in contact with water. The switch can also be used to begin the steaming process, should you wish.
The control system of this espresso machine feels a bit old-fashioned, but it is user-friendly. It has a small LCD screen that appears like an LED. This makes it simple to navigate the menus, however there is a bit of a learning curve for people who aren't used to espresso machines. The machine's temperature stability is also impressive. It ensures a perfect water temperature of 194deg - the 208 degree F throughout the entire the brewing process. This ensures a perfect extraction of aroma and a top-quality cup each time.
