The difference between flat knife and Ghost Tooth of Bean Grinder Flavor description of Coffee Bean

As for flat Dao, it has the largest quantity on the market. Whether it is a single bean grinder or an Italian bean grinder. Whether it is the top commercial German Mehdi EK43 or the mid-range MAZZER MAJOR, or the Eureka MMG designed for home use. Flat knife grinder generally has a clear positioning, either the Italian brand MAZZER as the representative of the pure Italian grinder, or the German brand Mahdi as a single product grinder with table (some models can also be compatible with Italian coffee). Because of the difference in knife pattern design and adjustment design, most Italian brand Italian coffee grinders can only grind the fine powder suitable for Italian coffee, but not for the coarse powder of single coffee! In the field of flat knife, the quality of the product is directly proportional to the grade of the bean grinder and the diameter of the grinding plate. So much so that there is a famous saying in the coffee industry: the diameter of the grinding disc of the flat knife is the truth!

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 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.

The coffee particles ground by flat knife are flaky, and the flake can increase the area of cell wall, so using flat knife can increase the concentration and extraction rate of coffee liquid 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 becomes longer, the granular xylem will absorb too much water, resulting in increased miscellaneous flavor and astringent taste.
