Important Parts of an Espresso Machine
A top espresso machine should deliver a strong and thick-bodied shot of coffee with a full-bodied aroma and a strong flavor. This requires a high temperatures and pressure.
It is also important to pay attention to the crema, a golden brown layer that gives the espresso its distinctive color and taste. There are four types of espresso machines. They include semi-automatic, automatic, and manual.
Water reservoir
The water reservoir is the container in which you store the water that is cold, filtered and that is supplied to the espresso machine. It is usually removable and comes with lids that keep the water free of dust. It is a crucial component of an espresso maker and must be kept clean to prevent the clogging. To clean it, put vinegar in the reservoir and let it run for a few minutes.
The espresso machine uses water to pressurize coffee grounds to extract flavors as well as caffeine, oils and flavor. It also creates the foam called crema. The first espresso machines were designed by Achille Gaggia, who used pistons attached to levers to create high-pressure coffee. Gaggia's spring-piston levers moved the water through the coffee and into the cup, and introduced new terms for what people referred to as "coffee cream" (crema).
The pump makes use of electricity to push water through the heating element to heat it up to the ideal brewing temperatures of 195 degrees Fahrenheit. The pump is usually situated at the bottom of the machine. It is connected to a tube which goes through the heating elements. The tube also connects at either end to the cold-water tube as well as the hot-water tube. It also runs under the resistive heating element, which is covered with white grease to keep the plate warm.
Pump
The pump is what makes an 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 between the sides of the form of a coil at 60 pushes per second. The pump then forces water through the portafilter, and out of the spouts. Other pumps use a heating system called thermoblock, also known as thermocoil, to heat the water precisely at the temperature desired for making. These systems also permit control of pressure as well as water temperature, which is crucial to a quality extraction.
Pump-driven espresso machines may use a piston, spring or electric pump. However,
bean to cup espresso machines require that water be transported through the grounds of coffee at a high pressure. The higher the pressure the more efficient the extraction. The pump makes sure that the coffee is evenly distributed and helps to create a good crema.
Other kinds of espresso machines are piston-driven or steam-driven. In a steam driven machine, the water is forced through the ground coffee by using steam pressure. This type of espresso machine is less expensive, but does not provide as much pressure for extraction. There are also air-pump-driven machines which are smaller and lighter, but do not require a boiler. They can be powered by a hand pump or a canister of compressed air (such as N2 or CO2). Air-pump espresso makers produce less pressured espresso than pump-driven machines, but may be more convenient for some people.
Steam wand
The steam wand is a thin metal pipe that comes out of the espresso maker and shoots steam that is hot and pressurized into your milk, resulting in foamy drinks like cappuccinos or lattes. You can also make hot water for cocoa or tea. The wand typically has a few holes on its tip, that you can turn off and on to regulate the amount of steam released. Certain machines come with the traditional wand while others have a Pannarello, which is easier to use, but doesn't produce foam that is suitable for latte art.
If you're experiencing problems with condensing milk, it could be that your espresso machine has a problem with its anti-vacuum device. This device was created in order to prevent air from getting absorbed into the steam wand as it is in operation. You can test it by lowering the steam wand while listening for a sound that makes a hiss. If you hear this noise it is a sign that air is being sucked into the wand and you need to raise the wand a bit to allow it to sink more deeply.
You can also test the anti-vacuum valve by taking off the wand, then cleaning it using warm water and a soft-bristled brush sponge. Cleaning the wand is crucial to avoid clogs that may hinder your frothing. If you're not able to fix it on your own, seek help from a technician or the manufacturer.
Control panel
The control panel of an espresso machine permits the user to set up and change settings. The settings include the strength of the coffee and milk quantity. These settings can be adjusted at anytime. The display displays when the machine is descaled, and when the reservoir for water is full.
The majority of espresso machines have hot water dispensers, either close to one of the groups or in between them. It can be used to make hot tea or heat cups in the event of need. It can also be used for cleaning and rinsing. There are many models with pressure gauges on the front of the machine, which indicate the current pressure in the boiler.
A brew switch is available, which controls both the brew cycle as in the quantity of shots. This is crucial as the size of espresso shots is determined by how long the grounds are in direct contact with the water. If you wish the switch could be used to start the steaming process.
The control system on this espresso machine is a bit outdated however, it provides easy-to use functions. It has a narrow LCD screen that looks more like an LED. This makes it simple to navigate the menus though there is some learning curve for users that are new to espresso machines. The ability of the machine to maintain the temperature at a constant level is impressive. The machine maintains a perfect water temperature between 194deg and 208deg F during the entire process of brewing. This guarantees a perfect aroma extraction and a premium cup each time.
