Important Parts of an Espresso Machine
A quality espresso machine will create a shot of espresso with a rich body, a rich flavor and an strong aroma. This requires a high temperatures and pressure.
You should also be attentive to the crema, which is a golden-brown layer that gives a rich espresso its characteristic color and taste. There are four kinds of espresso machines, including semi-automatic, automatic, and manual.
Water reservoir
The reservoir for water is the container that holds the cold, filtered water that is supplied to the espresso machine. It is usually removable, and comes with a lid in order to keep the water clean and dust-free. It is a vital component of an espresso machine and should be kept clean to avoid the clogging. To clean it, pour vinegar into the reservoir and let it run for several minutes.
The espresso machine makes use of water to pressurize coffee grounds to extract flavors, oils and caffeine. It also produces crema, the foam. Achille Gaggia designed the first espresso machines, which used levers and pistons to create high-pressure coffee brewing. Gaggia's spring-piston levers moved the water through the coffee and into the cup, introducing new jargon for what people referred to as "coffee cream" (crema).
The pump is an electric device that pushes the water through the heating element to raise it to the ideal temperature for brewing of 195 degrees Fahrenheit. It is usually situated at the bottom of the machine, and is connected to a tube that goes up through the heating element. The tube also connects at both ends to the cold-water tube and the hot-water tube. It also runs under the resistive heating element, which is covered in white grease, which helps keep the plate warm.
Pump
There are a variety of espresso machines. For instance certain machines use a vibratory or vibe pump, which uses an electromagnetic motor that moves back and forth within the coil to generate 60 pushes per second. The pump forces water into the portafilter, and then out of the spouts. Other pumps use an heating system, known as a thermoblock, or thermocoil, which heats the water precisely to the temperature desired for brewing. These systems permit the control of temperature and pressure, which is essential for a successful extraction.
Pump-driven espresso machines may use a piston, spring or electric pump. However, they all require that water be moved through the grounds of the coffee at a high pressure. The higher the pressure the better the extraction. The pump helps ensure that the coffee grounds are evenly dispersed, which helps make a good crema.
Espresso machines that are piston-driven or steam-driven are also available. Steam pressure is used to force water through the coffee grounds in a steam-driven espresso machine. This kind of espresso machine is more affordable, but doesn't produce the same amount of pressure for extraction. There are also pump-driven espresso machines which are lighter and smaller, but do not require a boiler and can be powered by hand pumps or a canister filled with compressed air (such as N2 or CO2). Air-pump espresso makers yield less espresso than pumps-driven machines, however they may be more suitable for certain people.
Steam Wand
The steam tool is a thin metal pipe that shoots hot pressurized Steam into your milk for foamy drinks like cappuccinos and Lattes. You can also use the wand to create hot water for tea or cocoa. The wand has several holes that can be turned on or off to regulate the amount of steam released. Some machines come with a traditional wand while others have a Pannarello wand, which is more user-friendly but doesn't create the same foam needed for latte art.
If you're having problems frothing milk, it could be that your espresso machine has a problem with its anti-vacuum device. This device is designed best espresso maker to prevent air from sucking into the steam wand during operation. You can test it by lower the steam wand and listening for a hissing noise. If you hear this sound it is an indication that air is being sucked in and you should raise the wand just a little so that it is submerged more fully.
You can also test the valve for anti-vacuum by removing the wand and washing it using warm water and a soft-bristled brush or sponge. It is vital to clean the wand to avoid clogs which could affect your foaming. If you are unable to fix it yourself, call a professional or the manufacturer.
Control panel
The control panel of an espresso machine allows users to configure and alter settings. These include the strength of the coffee and volume of milk. These settings are stored in memory and can be altered at any time. The display also shows the time when the machine has to be descaled as well as if the water tank is full.
Most espresso machines have hot-water dispensers, either in one of the groups, or between them. It can be used to prepare coffee or to heat cups when needed. It can also be used for cleaning and rinsing. Many models have pressure gauges on the front of the machine, indicating the current pressure in the boiler.
There is also a brew switch, which controls the brew cycle and the amount of shots. This is important, as the size of espresso shots is determined by how long the grounds are in direct contact with the water. The switch can also be used to start the steaming process should you wish.
The control system on this espresso machine may be a bit outdated, but it offers easy-to-use functionality. It has a small LCD which feels more like a simple LED. This makes it simple to navigate through the menus, however there's a bit of a learning curve for people who are new to espresso machines. The stability of the temperature is impressive as well. It keeps a perfect temperature of 194deg - the 208 degree F throughout the entire the brewing process. This ensures a perfect extraction of aroma and a premium cup every time.
