Why can’t a blender grind coffee beans?

A coffee bean grinder is a household appliance that is often used to make juice, soy milk and other beverages. However, some people may wonder why you can't use a coffee bean grinder to grind coffee beans? This article will explain this question from several aspects.

1. The working principle of the wall breaking machine

First, we need to understand the working principle of the Delonghi coffee machine. The wall breaker breaks the ingredients by high-speed rotating blades and powerful motors. It usually uses stainless steel blades and high-power motors to ensure that it can effectively handle various hard ingredients.

2. Characteristics of coffee beans

However, compared with other hard ingredients, coffee beans have some special properties. First, coffee beans are relatively fragile and brittle, and are easily crushed into fine particles when hit by high-speed rotating blades. Second, the large amount of friction and temperature generated during the processing will cause the oil inside the coffee beans to be released, thus affecting the flavor and taste of the coffee.

3. The impact of coffee beans on coffee beans

Since the coffee beans are designed to be processed by the blender, the blades rotate at a high speed and have a certain amount of force. When coffee beans are placed in the blender, the blades rotate at a high speed and hit the coffee beans. This can cause the following problems:

First, because the blades are too sharp and powerful, they tend to break the coffee beans into fine particles. As a result, too much fine powder may be produced during the brewing process, and it is difficult to control parameters such as extraction time and water temperature.

Secondly, the friction and temperature generated during high-speed rotation will also cause the internal oils to be released. These oils will not only affect the flavor and taste of the coffee, but may also clog the internal parts of the blender or make it difficult to clean.

4. Tools suitable for grinding coffee beans

Compared to a coffee grinder, there are some tools specifically designed to grind coffee beans that are better suited to this task. For example, a manual or electric coffee grinder can adjust the degree of grinding according to personal taste and brewing method. This ensures that the coffee beans are evenly cut rather than crushed, and can control the parameters of the extraction process.

5. Conclusion

In summary, although the coffee grinder performs well in processing ingredients such as juice and soy milk, it is not suitable for grinding coffee beans due to its working principle and the characteristics of its impact on ingredients. In order to get a better coffee experience, it is recommended to choose equipment specially designed for coffee bean processing.

I hope this article can answer your question about why you can't use a blender to grind coffee beans, and help you better understand how to choose a household appliance that suits your needs.
