How a Coffee Machine Works
A coffee maker makes it easy to brew an espresso at home. They automate the process, and take charge of all the work.
Whether you're a snoozer who requires a quick jolt, or an espresso lover, there's a machine for all. Learn how they work to make the perfect cup.
The Reservoir
You add water to a reservoir, and from there it flows through the rest of your coffee maker. You place your coffee grounds into the portafilter, and then tamp them down. Then, you turn on the machine.
Drip coffee machines are a standard and are a time saver for those who prefer a cup of joe that's ready when they wake up. The machine comes with a variety of features that allow you to personalize your experience, such as a timer that can be programmed and the option to use capsules or ground coffee.
Keep your reservoir clean to prevent the build-up of limescale. This can lead to mineral deposits that can affect the taste. After every brewing session, it's important to empty and refill the reservoir with clean water. To remove vinegary smells and stains in the reservoir, fill it with warm water mixed with white vinegar. Make a brew cycle, then discard the vinegar-water mix and rinse the reservoir, the portafilter, and the holster of the K-cup pod using hot water and dish soap in the sink.
The Cold-Water Tube
The cold-water tube is responsible to bring fresh purified water to the heating chamber when it's time to brew. Once it's in the heating chamber, it's then pumped into the showerhead, where hot water is sprayed over the ground coffee. This is a way of infusing the coffee grounds, extracting their flavor and then spilling into the carafe below.
If you hear a clicking sound, this could be an indication of a blockage in the tubing. These can be resolved by cutting a piece of standard household tubing and fitting it to the inlet fitting on the coffee maker, using an adapter in the event that it is required.
The one-way valve can be located in the bucket opening or inside the aluminum tube. It is responsible for bringing cold water into the tubing after the reservoir has been empty and then releasing hot water boiling back into it once the tubing is ready to be used. This valve can produce a sound when it is clogged with dirt or mineral deposits. It can be easily cleared with a toothpick or other thin instrument.
The Hot-Water Tube
There's a small tube of aluminum inside your coffee maker that connects the reservoir with the shower head faucet (also called the showerhead). When you press a button to start making your coffee the heating element is turned on and water begins to pass through the machine. The tube is insulated so that the water stays hot when it moves from section to section.
Sensors turn the water off and on after it has reached the reservoir to ensure that it remains at the ideal temperature for coffee extraction, which is 195-205 degrees F. Certain machines have a temperature probe to ensure that the water is always at the right temperature.
The water then turns into steam which rises up through a hole in the bucket. It then passes over the coffee's coarse grounds in a filter basket on the top of the machine. The hot water continuously soaks the grounds, extracting the flavor, before pouring into the carafe. Certain models have a pre-infusion water system that is used to wet the grounds with low-pressure water prior to the pressure is fully reached, further enhancing extraction.
The Faucet
Coffee machines are little devices that do a lot to convert the water they receive into hot coffee. Understanding how they function will help you understand why they're so popular and why it's vital to keep them running.
The coffee machine faucet is a showerhead that spouts water from the hot-water tube onto the coffee grounds. The water is pumped through a perforated plastic disc, known as the drip area, and the rate that it falls over the grounds determines the amount of moisture released into the coffee.
Certain models with advanced features come with a built-in grinder to ensure that the coffee beans are freshly ground prior to when they are placed in the heating chamber. They can also be programmed to brew before you wake up, meaning that when your alarm goes off your coffee is ready. They can be equipped with an app that allows you to choose a beverage and alter the milk and coffee ratios.
The Drip Area
The coffee machine is easy to use, but it does much to transform water into delicious cups. In this section of the machine, you'll discover the various components that create the magic.
There's a reservoir bucket which holds the water you pour into at the beginning of the cycle, and there's a white tubing that connects the base of the reservoir to the drip area. The tube's function is to carry hot water which will be sprayed on your lawn.
The shower head is the next, which receives the hot liquid that is carried by the tube and then sprays it onto your beans that you've ground. This is where the brewing process starts, and it's here that the flavor of your brew will begin to emerge. You can modify the final outcome of your brew by making alter the brewing temperature and time (some coffees require longer brewing times or higher temperatures to extract their full flavors). The final product will run through a tiny disc, referred to as a drip area and into your cup below.
The Heating Element
Heating elements are found in nearly every coffee maker. It is made up of resistive cables that heats up when electricity flows through it. There is also a switch to turn the power off and on to stop the coil from becoming too hot. The coffee machine also has components such as sensors and fuses that cut off the current when needed.
The aluminum water tube that transports hot water from the reservoir to the faucet is connected on both ends to the heating element. The resistive heating elements are sandwiched between the aluminum tube and a warming plate that is covered with white heat-conductive grease.
Drip coffee machines make one cup of coffee at one time. This is great for those who don't wish to fill a carafe and simply want an easy cup of java. These machines are also ideal for people who don't drink coffee often or families with a different wake-up time. Espresso machines are best for those who like stronger drinks, such as cappuccinos and lattes. They make use of pressure to push the water through the ground, which extracts the oils that give your beverage its flavor.
The One-Way Valve
A one-way valve, also referred to as a check valve allows fluid to flow through it in only one direction. This valve is found either in the hole in the reservoir or in the aluminum tube that carries the water under the heating element that is resistive. This valve prevents cold water from returning into the bucket while forcing bubbles of boiling water to upwards in the tube to the faucet.
The one-way valve can be blocked. This can happen when the machine is used for a prolonged time or if minerals accumulate inside the valve. This could result in the coffee machine not making any coffee. If this happens, you should clean the valve by pouring hot tap water over it. Take here off the base of the coffee machine.
The coffee maker is a smart device that can turn the smallest amount of grounds and a cup of water into a steaming hot cup of coffee. There are a variety of advanced features available on these machines that give you more control over your drink.
The Power Cord
The power cord connects to the wall and provides the energy for this machine to work. It is black and grounded with a female C13 connector that plugs into the standard US outlets. Inside the coffeemaker you can see a special high temperature wire that connects to the thermostat control and switch for both the boiler and carafe heater. This wire is made of white glass braid or similar insulation. The heating elements reach boiling point and can be cooled by a few degrees which is why it makes sense that the designer arranged the wiring to shield heat from the power cord that is coming in.
