Do you know why the blender cannot grind coffee beans?

The reason why the wall breaking machine cannot grind coffee beans

A coffee grinder is a common household appliance that can grind nuts, grains, and other ingredients into powder or paste. However, some people may find that despite its powerful functions, coffee beans are not well processed by coffee grinders. So, why can't coffee grinders grind coffee beans? Let's explore it below.

1. The design of the coffee bean breaker is not suitable for the characteristics of coffee beans

First, we need to understand the characteristics of coffee beans. Compared with other ingredients such as nuts and grains, coffee beans are harder and denser in shape. This means that greater force and higher speed are required to break them during processing.

However, most home coffee breakers are not designed and optimized for this special situation. They usually use low power and low speed to ensure safety and durability, and cannot provide strong enough force to effectively process hard and dense coffee beans.

2. The blade design of the coffee breaker is not suitable for grinding coffee beans

In addition to the power and speed issues, the blade design of the wall-breaking machine is also one of the reasons why it cannot grind coffee beans. Most home wall-breaking machines use multi-layer staggered blades, which work better when processing ingredients such as nuts and grains.

However, this blade design is not suitable for coffee beans. Since coffee beans are hard and dense, it is easy for the blade to get stuck or fail to break them completely during processing. In addition, since coffee beans are regular in shape and relatively small, they are easily trapped in the multi-layer staggered blades and cannot fully contact the cutting surface.

3. The wall breaker cannot provide a sufficiently fine grinding effect

In addition to not being able to completely break up the coffee beans, using a coffee breaker will also result in the resulting powder not being fine enough. Generally speaking, making high-quality coffee requires grinding the coffee beans into a uniform and fine powder so that the aroma and taste of the coffee can be fully released during the brewing process.

However, because the coffee breaker cannot provide strong enough power and suitable blade design, the resulting coffee powder is often not fine enough. This will reduce the contact area between water and coffee particles during brewing, thus affecting the release of coffee aroma and taste.

4. The coffee bean breaker has problems in retaining the flavor of coffee beans

In addition to the above points, using a grinder to grind coffee beans may also result in flavor loss. In traditional manual or electric grinders, the resulting powder size can usually be controlled by adjusting the spacing between the grinding discs and choosing the appropriate degree based on personal taste preferences.

However, there is no such flexible option to adjust the powder size and texture when using a coffee grinder. Therefore, when processing hard and dense coffee beans into powder, it may result in over-grinding or under-grinding, which affects the flavor of the coffee.

in conclusion

In summary, the main reason why coffee beans cannot be processed well by coffee breakers is that their design is not suitable for the characteristics of coffee beans, the blade design is not suitable, and they cannot provide a sufficiently fine grinding effect. Therefore, when choosing household appliances, if you want to be able to brew a cup of fragrant coffee freshly on site, it is recommended to purchase equipment specifically for coffee bean processing.

Of course, when there is no professional equipment available, you can also consider using other methods to process coffee beans. For example, manual or electric grinders can better meet the needs of people who have requirements for powder size and texture. In short, it is very important to choose the right tools when enjoying delicious coffee.
