Working mechanism of fully automatic coffee machine and coffee bean requirements

Fully automatic coffee machines have gained wide popularity for their convenience and consistency. Their working principle involves several key steps, including grinding of coffee beans, extraction and final coffee making. First, the machine's built-in grinder grinds the coffee beans to the desired coarseness. The coarseness of the grind is crucial to the flavor of the coffee, because too coarse a grind will result in a thin taste, while too fine a grind may produce a bitter taste. Fully automatic coffee machines usually allow users to adjust the grind setting to accommodate different types of coffee beans.

After the ground coffee beans are fed into the extraction system. Extraction is the process of passing high-temperature water through the ground beans to release their aroma and flavor into the liquid. The extraction process of the fully automatic coffee machine includes adjusting the water temperature, pressure and extraction time, which directly affect the flavor and taste of the coffee. The precise control of the machine ensures the stability and consistency of each cup of coffee.

The choice of coffee beans has a profound impact on the final taste of coffee. Beans of different varieties and roasting degrees will bring different flavor characteristics to coffee.

How to choose the right coffee beans for you

Choosing the right coffee beans is the key to enjoying delicious coffee. First, you need to understand the basic types of coffee beans, the two most common of which are Arabica beans and Robusta beans. Arabica beans usually have a more complex flavor and lower bitterness, suitable for coffee lovers who like delicate taste. Robusta beans, on the other hand, have a stronger bitterness and higher caffeine content, suitable for consumers who like strong flavors.

In addition to the type of beans, the freshness of the coffee beans is also an important factor when choosing. Freshly roasted coffee beans can bring richer aroma and flavor. When purchasing, you should try to choose beans marked with the roasting date to ensure that they are as fresh as possible. Beans that are expired or stored for too long may lose their original flavor.

The roasting degree of coffee beans will also affect the final taste of coffee. Lightly roasted beans retain more of the original bean flavor and usually taste sour and refreshing; medium roasted beans balance the acidity and bitterness, which is suitable for most people's taste; dark roasted beans have a stronger bitterness and smokiness, which is suitable for people who like a strong taste. The choice of roasting degree should be determined according to personal taste preference.

Taking into account the bean variety, freshness and roast degree can help you choose the coffee beans that best suit your taste so that every cup of coffee can meet your expectations.

Optimizing the matching degree between coffee beans and fully automatic coffee machines

The performance of a fully automatic coffee machine depends largely on the coffee beans that match it. Different coffee bean types and grinds will affect the extraction effect of the coffee machine, so it is important to understand these matching requirements. Fully automatic coffee machines are generally equipped with built-in bean grinders, which requires the degree of grind of the coffee beans to be adapted to the machine settings. Grinding too coarsely or too finely may result in the coffee machine being unable to effectively extract the flavor of the beans.

Generally speaking, most fully automatic coffee machines require the coffee beans to be ground to a medium coarseness. This degree of grinding can ensure uniform extraction without excessive wear on the coffee machine. When choosing beans, it is recommended to choose coffee beans marked as suitable for medium grinding. For users who want to adjust the flavor, they can try different grinding settings to find the best match.

In addition, the freshness of the coffee beans is also a key factor. Freshly roasted coffee beans can fully develop their flavor in the fully automatic coffee machine. Choosing fresh beans and avoiding long-term storage can effectively improve the overall quality of the coffee. If you find that a certain type of coffee beans does not perform well in the machine, you may need to adjust the grinding degree or try changing

Best storage methods and preservation tips for coffee beans

In order to maintain the freshness and flavor of coffee beans, the correct storage method is essential. First of all, coffee beans should be stored in a cool and dry environment. Avoid exposing coffee beans to direct sunlight or high temperatures, as these conditions will accelerate the oxidation of coffee beans, resulting in the loss of flavor and aroma.

The ideal storage temperature is around 20°C and humidity should be kept at a low level. High humidity can cause the coffee beans to become damp, which can affect the flavor and taste. Therefore, do not store coffee beans in a place with heavy humidity, such as near the sink in the kitchen.

Choosing the right storage container is also an important factor in keeping coffee beans fresh. The most ideal container is a sealed glass jar or ceramic jar, which can effectively block air and reduce the occurrence of oxidation. Avoid using plastic bags or paper bags because these materials do not provide sufficient isolation.

If you buy a large amount of coffee beans, it is recommended to divide it into small portions and take out the required amount each time.

Adjust coffee machine settings to optimize the flavor of different coffee beans

In order for a fully automatic coffee machine to bring out the best flavor of coffee beans, it is very important to know how to adjust the machine settings according to different coffee bean types. First of all, the grind size of coffee beans directly affects the extraction effect of coffee. For Arabica beans, this bean is usually suitable for medium or slightly fine grind, which can effectively release its rich flavor and aroma. For Robusta beans, a coarser grind helps reduce bitterness and enhance the strong feeling of coffee.

Adjusting the brewing time is also a key factor. Generally speaking, lightly roasted coffee beans require a shorter brewing time to maintain their fresh acidity and complex flavor. Deeply roasted beans can be brewed for a longer time to better release their rich bitterness and smoky flavor. By making appropriate adjustments, you can ensure that each roasted degree of beans can achieve the best extraction effect.

Water temperature also has a significant effect on coffee extraction. Most fully automatic coffee machines allow users to adjust the water temperature, and the generally recommended range is 90°C to 96°C. For lightly roasted coffee beans, a slightly lower water temperature (around 90°C) helps reduce the sharpness of the acidity, while for dark roasted beans, a slightly higher water temperature (around 96°C) can better release its deep flavor.

By understanding these adjustment tips, you can optimize the settings of your fully automatic coffee machine according to the type of coffee beans you use, thereby making more delicious coffee. Proper settings can not only improve the flavor of the coffee,
