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 a high temperatures and pressure.
You must also pay attention to the crema, a golden brown layer that gives an intense espresso its distinctive flavor and color. There are four major types of espresso machines: manual, semi-automatic automated, super-automatic, and semi-automatic.
Water reservoir
The reservoir of water is the container in which you store the water that is cold, filtered and that is supplied to the espresso maker. It is usually removable and has a lid that keeps the water free of dust. It is an essential component of an espresso maker and should be kept clean in order to prevent the clogging. Pour vinegar into the reservoir to clean it. Let it run for several minutes.
The espresso machine uses water to pressurize the coffee grounds to extract the oils, flavors, and caffeine. It also produces crema, which is the foam. Achille Gaggia designed the first espresso machines that used levers and pistons to create high-pressure making. Gaggia's spring piston levers pushed water through the coffee and into the cup, introducing new terms for what consumers called "coffee cream" (crema).
The pump is an electrical 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 on the bottom of the machine. It is connected to a tube that runs up through the heating elements. The tube is connected at both ends to hot-water and cold-water tubes. It also goes under the heating element that resists heat, that is covered with white grease, which helps keep the plate warm.
Pump
The pump is what makes an espresso machines work, and there are several types. Some machines employ a vibratory pump, also known as a vibe pump, which uses an electromagnetic motor to move back and forth in a coil at 60 pushes per second. The pump then pushes water through the portafilter, and out of the spouts. Some pumps employ thermoblocks or a thermocoil heating system, which heats the water precisely to the temperature that is desired for making. These systems also permit the control of water pressure and temperature, which is crucial to a quality extraction.
Pump-driven espresso machines may use a piston, spring or electric pump. But, they all require that water be transported 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 ground is evenly distributed, which helps make a good crema.
Steam-driven and piston-driven espresso machines are also available. Steam pressure is used to force water through the grounds of coffee in a steam-driven espresso machine. This type of machine is cheaper however it does not provide the same amount of pressure for extraction. There are also air pump-driven espresso machines that are smaller, lighter and do not require steam boilers. They can be powered either by a hand pump or canister that is filled with compressed air (such CO2 or N2). The espresso makers that are driven by air have lower pressure than pumps-driven espresso machines but may be more convenient for some.
Steam tool
The steam wand is a thin metal pipe that comes out of the espresso machine and shoots hot, pressurized steam into the milk to create foamy drinks like cappuccinos or lattes. The wand can be used warm cocoa, tea, or other hot drinks. The wand is usually made of several holes on the tip, that you can turn on and off to control the amount of steam released. Some machines come with an old-fashioned wand, while others use a Pannarello, which is easier to use, but doesn't make foam that is suitable for latte arts.
If you're having issues in frothing milk, it might be because your espresso machine is having issues with its anti-vacuum device. The valve is designed to prevent air from getting into the steam wand when it is in use. You can test this by lowering the wand and hearing a whirring sound. If you hear a sound that is hissing, this means air is being drawn into. You check here should raise the wand to allow it to sink completely.
You can also test the anti-vacuum using the wand and then cleaning it in warm water using a soft bristled brush or sponge. Cleaning the wand is essential to prevent clogs that could hinder the frost. If you are unable fix it yourself, you can seek help from a technician or the manufacturer.
Control panel
The control panel allows users to modify and configure settings. These include the strength of the coffee and volume of milk. The settings can be modified at any time. The display shows when the machine must be descaled and also when the reservoir for water is full.
The majority of espresso machines have a hot water dispenser. This is usually placed next to or between the groups. It can be used to make tea or to warm cups if needed. It can also be used to clean and rinse. A lot of models have gauges for pressure on the front of the machine that indicate the current pressure in the boiler.
A brew switch is also available, which controls both the brew cycle as well in the quantity of shots. This is important as espresso shot size is determined by the length of time that the grounds are in contact with the water. If you wish the switch can be used to initiate the steaming process.
The control system of this espresso machine feels a bit outdated, but it provides easy-to-use functions. It has a narrow LCD that is more like an ordinary LED. This makes it simple to navigate through the menus, though there is some learning curve for users that aren't familiar with espresso machines. The machine's temperature stability is impressive as well. The machine maintains a perfect water temperature between 194deg and 208deg F throughout the entire process of brewing. This guarantees a perfect aroma extraction and a premium cup each time.
