Important Parts of an Espresso Machine
A quality espresso machine will make a shot of coffee with a firm body that has a full flavor and an intense aroma. This requires high temperature and pressure.
You should also be aware of the crema, a golden brown layer that gives an intense espresso its characteristic color and taste. There are four major kinds of espresso machines: manual, semi-automatic automatic, super-automatic and semi-automatic.
Water reservoir
The reservoir for water is a container in which you can store cold, purified water that is fed into the espresso machine. It is usually removable and comes with a lid in order to keep the water fresh and free of dust. It is an essential part of an espresso maker and should be kept clean in order to prevent the clogging. Pour vinegar into the reservoir to wash it. Let it run for several minutes.
The espresso machine uses water to pressurize coffee grounds and extract flavors as well as caffeine, oils and flavor. It also produces crema, the foam. Achille Gaggia was the inventor of the first espresso machines, which utilized pistons and levers for high-pressure coffee brewing. Gaggia's spring-piston levers moved 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 pushes the water through the heating element to raise it to the ideal temperature for brewing of 195 degrees Fahrenheit. The pump is usually located at the bottom of the machine. It is connected to a tube which is pushed upwards through the heating elements. The tube is connected to hot-water and cold-water tubes. It is also connected to the resistive heating element which is coated with white grease that helps keep the plate warm.
Pump
The pump is what makes espresso machine work, and there are several kinds. Certain machines utilize a vibratory pump, also known as a vibe pump, that makes use of an electromagnetic motor that moves back and forth in a coil with 60 pushes per second. The pump then pumps water through the portafilter and out of the spouts. Some pumps employ thermoblocks or thermocoils as a heating system, which is able to precisely heat the water to the desired temperature for the brewing. These systems permit the control of water temperature and pressure, both of which are important for a quality extraction.
Pump-driven espresso machines may feature a spring or piston design or an electric pump, but they all require water to flow espresso machines home through the coffee grounds under high pressure. The higher the pressure the better the extraction. The pump makes sure that the coffee is evenly distributed and helps to produce good crema.
Other kinds of espresso machines are steam-driven or piston-driven. In a steam-driven machine, the water is pushed through the coffee using steam pressure. This model is more affordable however it does not provide the same amount of pressure for extraction. There are also air-driven espresso machines that are smaller, lighter and do not require steam boilers. They can be powered by a hand pump or canister filled with compressed air (such N2 or CO2). Air-pump-driven espresso makers have less pressure than pump-driven espresso machines, but they may be more suitable for some.
Steam Wand
The steam wand is the thin pipe made of metal that comes out of the espresso machine and shoots hot, pressurized steam into your milk to make foamy drinks like cappuccinos or lattes. You can also use the wand to create hot water for tea or cocoa. The wand usually has several holes in the tip that you can turn off and on to regulate the amount of steam released. Some machines have a traditional wand and others come with a Pannarello, which is easier to use, but doesn't produce foam that is suitable for latte art.
If you're having trouble in frothing milk, it might be because your espresso machine is having issues with its anti-vacuum device. This valve is designed to stop air from flowing into the steam wand when it is in use. You can test this by lowering the wand, and listening for a hissing sound. If you hear this noise, it means that air is being drawn into the wand and you need to raise the wand a bit to let it submerge more completely.
You can also test the anti-vacuum using the wand and washing it in warm water using a soft bristled brush or sponge. Cleaning the wand is vital to avoid clogs that can affect the frost. If you're unable fix the problem yourself, you can always call an expert technician or manufacturer for assistance.
Control panel
The control panel of an espresso machine allows the user to set up and modify settings. These include coffee strength as well as volume of milk. These settings can be adjusted at any time. The display also shows when the machine needs to be descaled and shows if the water tank is full.
Most espresso machines have hot water dispensers, either close to one of the groups or in between them. It can be used to make tea or heat cups, in the event of need. This is also great for cleaning and rinsing. Many models feature pressure gauges that display the current boiler pressure.
A brew switch is also available, which controls the brew process as well as the number of shots. This is crucial as the size of the espresso shot is determined by the length of time the grounds are in direct contact with the water. If you wish the switch can be used to initiate the steaming process.
The control system for this espresso machine is outdated however, it provides easy-to use functions. It features a narrow LCD screen that looks more like an LED. It is simple to navigate through the menus. However, there is a slight learning curve for those who are unfamiliar with the use of espresso machines. The machine's ability to keep an unbeatable temperature is remarkable. It can maintain a consistent water temperature of 194deg - the 208 degree F throughout the entire the brewing process. This allows for perfect aroma extraction and guarantees an even, high-quality, consistent cup each time.
