Important Parts of an Espresso Machine
A good espresso machine will give you a shot with a dense body with a rich taste and an strong aroma. This requires high levels of temperature and pressure.
Pay close attention to the crema. This golden-brown layer is what gives rich espressos their distinctive taste and color. There are four kinds of espresso machines: manual, semi-automatic, automatic and super-automatic.
Water reservoir
The water reservoir is a container which holds filtered, cold water that is fed to the espresso machine. It is usually removable, and comes with a lid to keep the water fresh and free of dust. It is a vital component of an espresso machine, and should be kept clean to avoid getting blocked. To clean it, add vinegar to the reservoir and let it run for about a minute.
The espresso machine makes use of water to pressurize coffee grounds and extract flavors as well as caffeine, oils and flavor. It also produces crema, which is the foam. Achille Gaggia was the inventor of the first espresso machines that used pistons and levers to produce high-pressure making. Gaggia's spring piston levers pushed water through the coffee and into the cup, introducing new terms for what people referred to as "coffee cream" (crema).
The pump is an electrical device that moves the water through the heating element to raise it to the ideal brewing temperature of 195 degrees Fahrenheit. The pump is usually found on the bottom of the machine. It is connected to a tube which runs through the heating elements. The tube is also connected on both ends to the cold-water tube and the hot-water tube. It also passes underneath the heating elements that resist heat, which are covered with white grease to keep the plate warm.
Pump
The pump is what makes espresso machine work, and there are several types. Some machines use a vibratory pump or vibe pump that makes use of an electromagnetic motor to move back and forth in the form of a coil at 60 pushes per sec. The pump then pumps water through the portafilter, and out of the spouts. Other pumps use a thermoblock or thermocoil heating system that is able to precisely heat the water to the desired temperature for brewing. These systems also allow control of pressure and water temperature, which are crucial for a high-quality extraction.
Pump-driven espresso machines can include a spring or piston design or an electric pump, but they all require water to pass through the coffee grounds under high pressure. The higher the pressure, more flavorful the extraction. The pump makes sure that the coffee is evenly distributed and helps create a good crema.
Other kinds of espresso machines are piston-driven or steam-driven. In a steam-driven espresso machine, the water is pushed through the ground coffee by using steam pressure. This type of machine is cheaper but does not produce the same amount of pressure for extraction. There are also air-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 CO2 or N2). Pump-driven espresso makers use less pressure than espresso machines driven by pumps, but they may be more convenient for some.
Steam tool
The steam wand is the thin metal pipe that is inserted out of the espresso machine and shoots steam hot and pressurized into your milk, resulting in foamy drinks such as cappuccinos and lattes. The wand can be used warm water for cocoa, tea, or other hot drinks. The wand generally has several holes on its tip, that you can turn off and on to regulate how much steam is released. Some machines have traditional wands, while others have a Pannarello wand that is more simple to operate, but doesn't produce the same type of foam needed for the latte art.
If you're having problems frothing milk, it could be that your espresso machine is having issues with its anti-vacuum device. The valve was designed in order to prevent air from getting absorbed into the steam wand while it is in operation. You can test this by lowering the wand, and listening for a sound that screams. If you hear a sound that is hissing it means that air is being drawn in. You need to raise the wand a little to submerge it fully.
You can also test the valve that controls the anti-vacuum by taking off the wand and cleaning it using warm water and a soft-bristled or soft-bristled sponge. It is important to keep the wand clean to avoid clogging, which could impact your frost. If you are unable to fix it yourself, call a professional or the manufacturer.
Control panel
The control panel allows users to alter and configure settings. Included are the strength of coffee and the quantity of milk. The settings can be modified at anytime. The display also indicates when the machine must be descaled, and also indicates whether the water tank is full.
The majority of espresso machines have hot-water dispensers, which are usually adjacent to one of the groups, or between them. This can be used for tea or to heat cups if required. It can also be used to clean and rinse. There are many models with pressure gauges on the front of the machine, which indicate the current boiler pressure.
There is also a brew switch which controls the brew cycle and the amount of shots. This is important as espresso shot size is determined by the amount of time the grounds are in contact with water. The switch can be used to also start the steaming process, when desired.
The control system of this espresso machine is a little here old-fashioned, yet it has a user-friendly interface. It has a narrow LCD that is more like an ordinary LED. This makes it easy to navigate through the menus however there is some learning curve for users that aren't familiar with espresso machines. The stability of the temperature is impressive as well. It keeps a perfect water temperature of 194deg - the 208 degree F throughout the entire making process. This guarantees perfect aroma extraction and a superior cup every time.
