Research on the grinding gears of coffee beans in the wall breaking machine

As people's pursuit of coffee becomes higher and higher, coffee bean grinders have become a common coffee making tool in households. When using a coffee bean grinder, it is very important to choose the right grinding gear. This article will focus on the exploration of coffee bean grinding gears of coffee bean grinders, and deeply analyze the impact of different gears on the taste and flavor of coffee.

1. Low speed gear

The low speed gear means setting the grinder at a lower speed for grinding. This method is suitable for lightly or medium roasted coffee beans, which can retain more of the original flavor and aroma. Due to the slow speed, it will not generate excessive friction and high temperature, avoiding bitterness and burnt taste.

However, the powder particles produced at low speed are relatively large and less uniform. Therefore, it takes longer for the water to fully contact the powder and extract the flavor of the coffee during brewing. At the same time, the powder ground at low speed tends to produce more fine particles, which may cause clogging of the filter paper filter.

2. Medium speed gear

The medium speed gear means setting the machine to grind at a moderate speed. This method is suitable for coffee beans of various roasting degrees and can obtain a more uniform and fine powder. Due to the moderate speed, it will not generate too much high temperature and friction.

The powder particles produced at the medium speed are of moderate size and have good uniformity. The water and powder are in full contact during brewing, and the extraction effect is good. At the same time, it is not easy to cause clogging when using filter paper filters.

3. High speed gear

High speed gear means setting the machine to grind at a higher speed. This method is suitable for coffee beans with deep roasting or special requirements, and can obtain more delicate and uniform powder.

However, the powder particles produced at high speed are very fine, which can easily produce too many fine particles. These fine particles may pass through the filter paper and enter the coffee, causing precipitation or turbidity. In addition, due to the friction and high temperature at high speed, it is easy for the coffee beans to lose part of their original flavor and aroma.

4. Gear selection tips

When choosing the grinding level of the blender, you need to consider factors such as personal taste preferences, coffee bean roasting degree, and brewing method.

If you prefer to retain more original flavor and aroma and use a more traditional brewing method (such as hand pouring), you can choose a low speed gear. This will give you a soft taste, obvious acidity, and rich sweetness.

If you want a more uniform and fine powder, and use a paper filter for brewing (such as drip coffee), you can choose a medium speed. This will give you a balanced taste, moderate acidity, and a refreshing and smooth coffee.

If you want a finer and more uniform powder and use a special brewing method (such as immersion), you can choose a high speed gear. This will give you a rich taste, lower acidity, and a strong aroma of coffee.

in conclusion

In the exploration of coffee bean grinding gears of the coffee bean breaker, different gears have a significant impact on the taste and flavor of coffee. The low speed gear is suitable for retaining the original flavor and aroma, the medium speed gear is suitable for uniform and fine powder, and the high speed gear is suitable for fine and uniform powder. Therefore, when choosing the grinding gear, you need to weigh the trade-offs based on your personal preferences and brewing methods.

Finally, I would like to remind everyone that when using a wall breaker for grinding, you must pay attention to the operating specifications, and adjust and try according to your actual situation to achieve the best results.
