Coffee Machine

Reservoir

There is this thing called the “reservoir” that holds the water you pour into the start of the coffee making cycle. At the bottom of the reservoir, there is a hole that is connected to a white tube that transfers the water.

Shower head

There is a shower head where water from the reservoir and tube gets sprayed over the coffee grounds. In some other machines, the water comes out of a hose that is on this drip area disc that has holes in it. The water falls though the holes and to the coffee grounds.

Heating element

There is a coil/plate component that is made out of aluminum with 2 parts. As the water goes through the heating element, the water gets heated.

Conclusion

The mixed coffee water then comes out the brew basket/filter and you can now have coffee.

Solar energy

As solar energy gets collected by solar panels it gets transferred to the outlets of the house.

Electric energy

When you first plug this technology device into the outlet, electricity/electric energy surges through the wire and to the machine.

Thermal energy

The electric energy then turns into thermal energy, and that heats the water in the machine. As the coffee grounds get mixed with the water, it becomes coffee.

Mechanical energy

There is also mechanical energy when the machines get turned on and the hole opens so that the coffee can come out.

Sound energy

When the coffee comes out of the machine, it creates sound energy.

Chemical energy

Obviously, coffee is also a source of chemical energy as it stores energy.

The solar energy collected by solar panels gets transferred into electric energy. As that electric energy surges through the coffee machine to power it up, the electric energy ends up turning into thermal energy since the electric energy powers the heating elements. After, as the coffee hole opens, mechanical energy happens since the closed hole opens automatically . Then, when the coffee drips, it creates sound energy. Lastly, while you drink it, you are receiving chemical energy.

Conduction

The heating elements/components touch the water, causing the water’s temperature to rise. It’s similar to cooking on a stove with a pan.

Convection

When the water gets heated, it rises because of its lower density. Cooler water then replaces the hot water. A mini water cycle is made in the reservoir of moving hot and cold water, up and down. This movement helps the coffee to be evenly hot throughout the drink.

Radiation

While this is not a primary heat transfer, it does happen. The heating elements/components radiate heat and this helps the water to heat up quicker.

Problem

Having a coffee machine can be really handy. It gets annoying going out to purchase coffee, especially in the morning when you just woke up and don’t want to do a lot of moving.

Solution

However, having a coffee machine at home fixes this issue. You only have to walk to your kitchen, put in some instant coffee, press a button, and wait for the vibration to make the coffee come out.

Benefit

Having your own coffee machine means you can also make combinations of coffees to cater to your taste. It’s quick and safe as long as you know how it works and what to do. There is also less waste as you are using a reusable mug, cup, etc.

Fact 1

As coffee undergoes the roasting process, its caffeine content diminishes, meaning that a dark, "bold" coffee contains lower levels of caffeine compared to a lighter roast.

Fact 2

Brazil holds the title of the biggest coffee producer globally, starting from the early 18th century when French settlers introduced the plant to the country. As Europeans developed a strong fondness for coffee, Brazil's production soared, securing its position as the leading producer by the 1840s and maintaining that status to this day. The Brazilian landscape has approximately 300,000 coffee farms.

Fact 3

The optimal time to consume coffee for maximum effectiveness is during the window between 9:30 am and 11:30 am. This timeframe concurs with a period when the majority of individuals have lower levels of cortisol, a steroid hormone produced by the adrenal glands situated on top of the kidneys. Elevated cortisol levels are typically released into the bloodstream during times of stress. Maintaining a proper balance of cortisol is crucial for overall well-being, as excessive or insufficient production of this hormone can lead to various health issues.

Fun Fact

According to legend, it is said that during the 9th century, a goat herder from Ethiopia unintentionally stumbled upon coffee when he saw how crazy his goats were acting.
