Can coffee beans be crushed by a wall breaking machine?

A wall breaker is a common household appliance that can grind nuts, grains and other ingredients into fine powder. However, for a special ingredient like coffee beans, is it suitable to use a wall breaker to grind it? This article will discuss this issue.

1. The working principle of the wall breaking machine

First, we need to understand the working principle of the wall breaker. The wall breaker uses the high-speed rotating blades and the container to create a strong impact and shear force, thereby breaking the food into powder or slurry. This working method is very effective when processing hard ingredients such as nuts and grains.

2. Characteristics of coffee beans

However, coffee beans are different from other hard ingredients. Coffee beans are seeds extracted from plant fruits and processed. During the processing, a layer of skin is formed to protect the high caffeine content inside and is easily oxidized and deteriorated. At the same time, during the growth process, coffee beans absorb a lot of water, making their insides soft. Therefore, there are obvious differences in hardness and water content between coffee beans and other ingredients.

3. The impact of coffee beans on coffee beans

Based on the above characteristics, we can infer that the coffee bean crushing effect of the coffee bean breaker may not be ideal. First, under the action of the high-speed rotating blade of the coffee bean breaker, the outer skin of the coffee bean is easily peeled off and scattered into the powder. In this way, since the outer skin is rich in bitter substances and acidic substances, it may affect the taste when making coffee.

Secondly, under the violent impact and shear force of the coffee breaker, the coffee beans with soft interior and high water content are easily crushed or squeezed out of liquid. As a result, the ideal particle size and uniformity may not be obtained during the production process.

4. Alternatives

Considering that the coffee bean breaker is not suitable for crushing coffee beans, we can choose other more suitable tools to process coffee beans. Currently, there are coffee grinders on the market that are specifically used for grinding coffee beans. They use conical or flat disc blades for fine crushing, which can better control the particle size and uniformity.

In addition, for home use, manual grinders are also a good choice. Manual grinders grind coffee beans into small pieces by manually rotating blades, and because of their relatively simple operation and good portability, they also have advantages in retaining the original flavor and taste of coffee beans.

5. Conclusion

In short, considering the characteristics of coffee beans and existing tools, we do not recommend using a wall crusher to grind coffee beans. In contrast, equipment specifically designed for processing coffee beans, such as electric or manual grinders, are more suitable and can achieve better grinding effects and taste experience.

I hope this article can provide you with some precautions when using a blender to process food ingredients, and provide some reference for choosing the right tool.
