Which is better, the flat knife of the bean grinder or the ghost tooth? an introduction to the grinding characteristics of coffee beans

The uniformity of grinding is the most important thing to judge the quality of the grinder. uneven grinding will cause uneven extraction in the follow-up, often some parts of coffee powder have not been fully extracted, while some parts have been excessively extracted. finally, the whole cup of coffee has a bad smell. One of the most common problems is that fine powder will be produced during rough grinding, resulting in bitter coffee. Although there will be fine powder phenomenon in even the best grinder, the phenomenon of fine powder in some low-end bean grinders will be especially obvious.

The heat generated during grinding as mentioned in the previous article, the aromatic substances in coffee powder are very volatile, and the heat during grinding will accelerate this volatilization. A good grinder can control the heat within a certain range by reasonable torque. However, if people drink their own coffee at home, they only grind a small amount of beans, and the effect of fever is negligible.

Needless to say about the grinding speed, the more time-saving and labor-saving, the better. However, it should be noted that some low-end grinders simply increase the speed to improve efficiency, which will cause a large amount of heat as mentioned in the second point. A good bean grinder generally achieves the balance of heat production and efficiency through low speed and high torque.

As for the conical knife, this is also ten thousand jin of oil. Except for the top MAZZER ROBUR, most other products are compatible with Italian and individual products. However, there is a serious differentiation between the two levels in the world of conical knives, either tens of thousands of top Italian bean grinders or low-end entry-level products! Household entry-level products are represented by BARATZA ENCORE, and most household-grade cones are compatible with individual products and Italian style. However, the quality of the product is of different opinions. Because the cone knife has high efficiency and fast grinding speed, a good cone knife will have the right amount of fine powder in the product can significantly improve the hierarchical sense of coffee, so the standard bean grinder in many top cafes will choose it. However, some people will feel that fine powder leads to miscellaneous smell in coffee extraction and restrains the cone knife. As for how to choose, you really have to try this for yourself to understand! After all, what suits your taste is the best! The cone cutter is also favored by most manual bean grinders because of its high grinding efficiency. The HARIO 2TB grinder Lido 2 is a cone cutter design.

First, the small steel cannon has no decorative stickers.

Second, the small steel cannon bean warehouse and the lid are the same color, while the small Fuji bean warehouse and the lid are different in color.

Third, the Phillips screw on the scale knob of the small steel gun, and the scale knob of the little Fuji is a cover-like word screw.
