The difference between the small Fuji bean grinder and the flat knife-the ghost tooth grinder is mainly used for

The upper and lower cutters of the flat knife are placed in a parallel manner, so the coffee beans need to rely on the rotating force of the bottom cutterhead to push the coffee beans into the cutterhead, so the weight of the coffee beans placed on the top will affect the uniformity of the coffee beans entering the knife cutter. in addition, due to pushing, the number of collisions between coffee beans increases, resulting in an increase in the proportion of fine powder. This is the reason why the particle uniformity of the common flat knife bean grinder is slightly worse and the fine powder is more. However, the coffee particles ground by the flat knife are flaky, and the flake can increase the area of the cell wall, so using the flat knife can increase the concentration and extraction rate of coffee in a short time, so that the aroma of coffee can be significantly improved in a short time. At the same time, because the shape is long and the volume is smaller, when the extraction time is longer, the granular xylem will absorb too much water, which will increase the miscellaneous flavor and astringent taste.

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.

The conical knife grinder places a conical cutter head at the bottom, and then grinds it with the outer ring cutter head. After the coffee bean falls from above, it will pull the coffee bean down with the rotation of the conical cutter head, and then produce grinding action. Because of the relationship from top to bottom, the particles can push the coffee out without pushing. Compared with the peace knife grinder, the number of collisions between the particles will be reduced a lot. Therefore, the proportion of fine powder produced by the cone knife will be much less than that of the flat knife, and the uniformity of coffee grinding will be greatly improved. The cone knife grinding particles will be close to granules, resulting in longer water absorption path of coffee particles and longer internal contact with water, so the cone knife particles will release less soluble matter at the initial stage, resulting in a low concentration in a short period of time. At the same time, because the shape is granular, even if extracted for a long time, the xylem absorbs less water and is less likely to produce miscellaneous and astringent taste.
