Important Parts of an Espresso Machine
A good espresso machine should give a rich and strong shot of coffee, with a full-bodied flavor and intense aroma. This requires high pressure and temperature.
It is also important to pay attention to the crema, a golden brown layer that gives the espresso its characteristic color and taste. There are four primary types of espresso machines: semi-automatic, manual, automatic and super-automatic.
Water reservoir
The water reservoir is the container that houses the water that is cold, filtered and that is fed to the espresso machine. It is usually movable and has an lid that keeps the water free of dust. It is a crucial component of an espresso machine, and should be kept clean to avoid the clogging. To clean it, add vinegar to the reservoir and let it run for several minutes.
The espresso machine uses water to pressurize coffee grounds to extract flavors, oils and caffeine. It also produces crema, the foam. The first espresso machines were developed by Achille Gaggia. They employed pistons attached to levers to produce high-pressure brewing. Gaggia's spring-piston levers pushed the water through the coffee and into the cup, and introduced new jargon for what consumers referred to as "coffee cream" (crema).
The pump is an electrical device that pushes the water through the heating element to warm it to the ideal brewing temperature of 195 degrees Fahrenheit. It is usually located at the bottom of the machine and attached to a tube which runs through the heating element. The tube is also connected at either end to the cold-water tube and the hot-water tube. It also connects to the heating elements that resist heat, which are covered with white grease to keep the plate warm.
Pump
There are different types of espresso machines. Certain machines utilize a vibratory pump or vibe pump that uses an electromagnetic motor to move between the sides of a coil with 60 pushes per sec. The pump pumps water into the portafilter, and then out of the spouts. Other pumps use a heating system called a thermoblock, or thermocoil, to heat the water precisely to the temperature desired 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 could have a piston or spring design or an electric pump, however they all require water to pass through the coffee grounds under high pressure. The greater the pressure, the more flavorful the extraction. The pump makes sure that the coffee is evenly distributed and helps produce a great crema.
The piston-driven and steam-driven espresso machines are also available. Steam pressure is used to force water through the grounds of the coffee beans in a steam driven espresso machine. This kind of espresso machine is more affordable, but doesn't produce enough pressure for extraction. There are also air pump-driven espresso machines that are lighter, smaller and do not require a steam boiler. They can be powered by a hand-pump or a canister that is filled with compressed air (such N2 or CO2). Air-pump espresso makers make less espresso than pumps, but they can be more convenient for certain people.
Steam Wand
The steam wand is the thin pipe made of metal that comes from the espresso machine and shoots steam hot and pressurized into your milk, resulting in foamy drinks such as cappuccinos, lattes. The steam wand can also be used to warm water for tea, cocoa or other hot drinks. The wand has several holes that can be turned on or off to control the amount of steam released. Certain machines come with an old-fashioned wand, while others come with a Pannarello which is more simple to use, but doesn't make foam that is suitable for latte art.
If you're having trouble condensing milk, it could be that your espresso machine has a problem with its anti-vacuum device. This valve is designed in order to prevent air from getting absorbed into the steam wand while it is in operation. You can test it by lowering the steam wand while watching for a whirring sound. If you hear this noise it is a sign that air is being sucked in and you should raise the wand to submerge it more fully.
You can also test the anti-vacuum using the wand, then washing it with warm water using a soft bristled sponge or brush. Cleaning the wand is essential to avoid clogs which could hinder your frothing. If you are unable to resolve the issue on your own, then you can always contact an expert technician or the manufacturer for assistance.
Control panel
The control panel permits users to alter and configure settings. Included are the strength of coffee and the quantity of milk. These settings are saved in memory and can be altered anytime. The display will also indicate the time when the machine has to be descaled, and also indicates if the water tank is full.
Most espresso machines come with hot water dispensers. This is usually placed in between or next to the groups. It can be used to prepare hot tea or to heat cups in the event of need. It is also ideal for cleaning and cleaning. Many models feature pressure read more gauges that indicate the current boiler pressure.
There is also a brew switch which controls the brew time and the amount of shots. This is important because espresso shot size is determined by the length of time the grounds are in contact with the water. The switch can also be used to begin the steaming process if desired.
The control system for this espresso machine is a bit outdated however it has easy-to use functions. It has a slim LCD that is more like a simple LED. It is easy to navigate through the menus. However there is a little learning curve for those who are unfamiliar with the use of 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 making process. This ensures perfect aroma extraction and a superior cup every time.
