Important Parts of an Espresso Machine
A quality espresso machine must deliver a strong and thick-bodied shot of coffee, with a full flavor and intense aroma. This requires a high 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, which include semi-automatic, manual and automatic.
Water reservoir
The reservoir of water is the container that stores the water that is cold, filtered and that is supplied to the espresso maker. It is usually removable and has lids that keep the water free of dust. It is an essential component of an espresso maker, and must be kept clean to prevent blocking. To clean it, pour vinegar into the reservoir and let it run for a few minutes.
The espresso machine uses water to pressurize coffee grounds and extract flavors, oils and caffeine. It also produces crema, the foam. Achille Gaggia designed the first espresso machines, which utilized levers and pistons to create high-pressure coffee. Gaggia's spring-piston levers drove the water through the coffee and into the cup, introducing new terms for what was referred to by consumers as "coffee cream" (crema).
The pump is an electric device that is used to push the water through the heating element to heat it up to the ideal brewing temperature of 195 degrees Fahrenheit. The pump is typically located at the bottom of the machine. It is connected to a tube that runs through the heating elements. The tube is also connected on both ends to the cold-water tube as well as the hot-water tube. It also connects to the resistive heating elements which are covered with white grease to keep the plate warm.
Pump
The pump is the thing that makes espresso machines work and there are many kinds. Certain machines utilize a vibratory pump, also known as a vibe pump, that uses an electromagnetic motor that moves back and forth in a coil with 60 pushes per sec. The pump draws water into the portafilter, and then out of the spouts. Other pumps utilize thermoblocks or thermocoils as a heating system that is able to precisely heat the water to the temperature that is desired for making. These systems allow for the control of water temperature and pressure, which are important for a quality extraction.
Pump-driven espresso machines may employ a piston, spring or electric pump. However, all require that water be transported through the grounds of the coffee with high pressure. The higher the pressure the better the extraction. The pump makes sure that the coffee is evenly distributed and helps produce good crema.
The piston-driven and steam-driven espresso machines are also available. Steam pressure is used to push water through the grounds of the coffee in a steam-driven espresso machine. This model is more affordable however it does not provide the same amount of pressure for extraction. There are also pump-driven espresso machines which are smaller and lighter, but do not require a boiler. They can be powered by hand pumps or a canister filled with compressed air (such as N2 or CO2). Air-pump espresso makers yield less pressurized espresso than pumps, but they can be more suitable for certain people.
Steam tool
The steam wand is the thin metal pipe that comes out of the espresso machine and releases steam hot and pressurized into your milk to make foamy drinks such as cappuccinos, lattes. You can also make hot coffee or cocoa. The wand generally has several holes on the tip, that you can turn on and off to control how much steam is released. Some machines come with the traditional wand while others come with a Pannarello which is more simple to use but does not create foam suitable for latte arts.
If you're having problems in frothing milk, it might be that your espresso maker has a problem with its anti-vacuum device. This valve is designed to stop air from being sucked into the steam wand when it is operating. You can test this by lowering the wand, and watching for a hissing sound. If you hear a sound that is hissing it is a sign that air is being drawn in. You should raise the wand a little to submerge it fully.
You can also test the valve for anti-vacuum by removing the wand and cleaning it with warm water and a soft-bristled brush or sponge. Cleaning the wand is vital to avoid clogs that may impact the frost. If you're unable to fix it yourself, consult a technician or a manufacturer.
Control panel
The control panel of an espresso machine permits the user to set up and alter settings. These include the strength of the coffee and milk volume. These settings are stored in memory and can be changed at any time. The display also informs you that the machine requires to be descaled, and also indicates if the water tank is full.
The majority of espresso machines have a hot-water dispenser, either in one of the groups, or between them. It can be used to make tea or to warm cups if needed. It is also ideal for cleaning and rinsing. Many models feature pressure gauges that display the current pressure of the boiler.
A brew switch is also available, that controls the brew cycle as as the number of shots. This is crucial, since the size of espresso shots is determined by how long the grounds are in direct contact with the water. If desired, the switch can be used to initiate the steaming process.
The control system of this espresso machine feels a bit old-fashioned, yet it provides easy-to-use functions. It has a small LCD which feels more like an ordinary LED. It is easy to navigate through the best espresso maker menus. However there is a slight learning curve for those who are unfamiliar with the use of espresso machines. The ability of the machine to maintain a constant temperature is impressive. It maintains a consistent temperature of 194deg to 208deg F during the entire brewing process. This provides perfect aroma extraction and guarantees an exact, high-quality cup each time.
