If you are an avid admirer of coffee and can’t start your day properly without a cup, you must be familiar with a good quality coffee maker. It is that beautiful thing that produces the heavenly drink with the gentle push of a button – every time, just as you want it.
You may have wondered a few times what you would do if you didn’t have one of these bad boys. Would your days be the same as they are now? Of course not!
For majority of us, life would be miserable without coffee!
But have you ever wondered how this little machine works and how it makes you a delicious drink every morning? To be honest, you probably haven’t.
We’re going to explain to you exactly how a coffee machine works. This knowledge might help you in ways you can never imagine.
Essential Parts of a Coffee Maker
All machines have these basic parts: A water reservoir, a holder for the ground coffee, a heating unit and a dripping nozzle from where the coffee is dispensed.
In many of the machines today, you would find a separate reservoir for milk. With a lot of other machines, powdered milk is mixed with the hot water to form the milk.
An air pressure unit with a capacity varying from 9 to 15 bars is built into the machine. This is required to push water through the ground coffee.
Also you would occasionally find a steam hand at one side of the machine which helps to steam your coffee and gives it a smooth, silky touch – just like you want it.
Now the very first thing that happens when you pour water in the reservoir is heating. When switching the machine on, the water is heated up to a certain temperature and kept ready for use.
At this stage, the temperature is not the same because different drinks (like latte, cappuccino etc.) require different temperature and the machine doesn’t know that yet.
When you select the type of drink you need, the software sends a signal to the hardware and the heating unit heats the water to the required level.
The air pressure unit also helps the warm water to push through the ground coffee holder while the coffee is dripped through the nozzle in the dripping area.
Depending on the type of drink you selected, the machine may mix milk with it or it may not. If you have pressed the ‘Black Coffee’ button, the machine will not pour milk in it. And if you want your drink to be steamed very well, you would have the option to do so by dripping the steaming arm into your cup and steaming it as necessary.
Another very important and integral part of every machine is a filter.
There are various types of filters to choose from including paper and metal filters etc. It’s important to choose your coffee maker according to your preferred filter type.
Now that you have a basic idea of how a coffee machine operates, you might have guessed that there is no rocket science involved in its process.
If one morning, you find your machine isn’t working properly, you can probably figure out what went wrong.
The problem could also be related to the taste and smell. So, if that’s the case, you might need to consider descaling your coffee machine.
However, if it’s a physical problem with the machine, then we seriously don’t recommend you try to fix it yourself. There is no point in messing with it unless you are professionally qualified.
