Study on the working principle of American coffee machine

Abstract: This paper explores the working principle of American coffee machine. The coffee machine heats the water in the water tank through the heating system, making it boil and produce steam. The steam enters the grinder containing coffee beans through the pipe. The coffee beans release aroma and oil under high temperature and pressure, and mix with the steam to form rich coffee. The coffee flows into the collection place and can be enjoyed after filtering the residue. The American coffee machine has a simple design and convenient operation. It has become an indispensable beverage making tool in modern homes and offices.

In the busy modern life, American coffee has become a daily necessity for many people. Have you ever wondered how the American coffee machine that prepares fragrant coffee for you every day works? Let's explore the working principle of the American coffee machine.

1. Pressure system

One of the main components of an American coffee machine is its pressure system. There is a sealed pressure vessel inside the coffee machine. There is a certain pressure inside this container, which ensures that the coffee powder can be evenly pressurized, thereby extracting delicious coffee. When we add an appropriate amount of water and turn on the coffee machine, the water pump starts working, introducing water into the pressure pipe and transporting it to the heating element inside the coffee machine.

2. Heating element

The heating element is the core part of the American coffee machine. When water passes through the heating element, it will quickly heat up to a near-boiling state. In this process, the minerals and oxygen in the water will be fully activated, providing good conditions for the subsequent extraction process. The precise temperature control function of the heating element ensures the stability of the water temperature and avoids affecting the taste of the coffee due to excessively high or low temperature.

3. Coffee powder and filter paper

Users will add coffee powder and filter paper to another part of the coffee machine. The main function of the filter paper is to filter out impurities during the extraction process to ensure that the final coffee is pure and free of impurities. The coffee powder comes into contact with hot water to start the extraction process. In this step, the pressure system plays a particularly critical role. It ensures that the hot water can pass through the coffee powder layer under appropriate pressure to extract the coffee with the concentration and taste we want.

4. Dripping process

The extracted hot water mixed with the essence of coffee flows into the water collection area under the coffee machine through a specific pipe. At this stage, the control system inside the coffee machine will accurately control the dripping speed and time to ensure that every drop of water is fully extracted American coffee. Users can control this process by adjusting the buttons or knobs on the coffee machine.

5. Temperature and humidity control

In addition to the key parts mentioned above, temperature and humidity also have an important impact on the performance of American coffee machines. Appropriate temperature and humidity can ensure that the flavor of coffee beans is perfectly released during the extraction process. For this reason, modern American coffee machines are usually equipped with intelligent temperature control systems that can monitor and adjust internal temperature and humidity in real time to ensure that every cup of coffee can achieve the best taste.

6. Other auxiliary functions

Modern American coffee machines have many other auxiliary functions, such as automatic cleaning function, preset programs, etc. These functions make the use of coffee machines more convenient and efficient. These functions also improve the safety and durability of coffee machines and bring better user experience.

To sum up, this is a brief introduction to the working principle of American coffee machines. Behind the seemingly simple operation actually lies precise design and complex scientific principles. Every time you press a button, it is a perfect combination of technology and art, which brings us cup after cup of fragrant American coffee. However, the key to making coffee delicious is not only the working principle of the machine, but also our choice of coffee beans, careful adjustment of the extraction process, and cherishing and enjoying every sip.
