Why can't a blender grind coffee beans? Let's explore the reasons!

A coffee grinder is a common kitchen appliance that is mainly used to break hard ingredients such as nuts, grains, etc. However, although the coffee grinder performs well in processing these ingredients, it is not suitable for grinding coffee beans. Let's explore the reasons below.

First of all, coffee beans are fundamentally different from other ingredients. Coffee beans are a relatively fragile and brittle food, and their special aroma and taste need to be carefully preserved during processing. The coffee bean crusher usually uses high-speed rotating blades or hammers to crush, which will produce greater impact and friction. This treatment method will cause the coffee beans to be over-crushed and may generate excessive friction heat, thereby losing the original aroma and taste of the coffee beans.

Secondly, it is difficult to control the powder particle size when using a blender. Due to the strong force brought by the high-speed rotating blades or hammers, it is impossible to ensure that each particle can reach the ideal size and uniformity. This is very important for making coffee, because different coffee brewing methods require different powder particle sizes to achieve the best extraction effect. If you use a blender to process coffee beans, you are likely to get particles that are too fine or too coarse, which will affect the taste and quality of the coffee.

In addition, the design of the coffee grinder does not take into account the special requirements of grinding coffee beans. Generally speaking, the equipment specially used for grinding coffee beans usually has a more delicate and complex structural design. For example, the blade or cone type bean grinders commonly found in modern home coffee machines are made of special materials and processes, and can provide better control over particle size and uniformity.

In short, when choosing the right equipment, you should consider the characteristics of the ingredients themselves. Although the wall breaker performs well in processing hard ingredients, its working principle and structural design limit its scope of application and cannot meet the needs of grinding fragile foods such as coffee beans. Therefore, if you want to grind coffee beans, it is recommended to choose a coffee bean grinder or a manual grinder specially designed for this purpose. This can better preserve the original aroma and taste of the coffee beans and make more delicious coffee.
