Bean grinder ghost tooth flat knife cone knife-domestic small Fuji ghost tooth bean grinder

Bean grinders are generally classified by coffee extraction, which are divided into two categories: single coffee grinder and Italian coffee grinder! According to the structure of the grinding plate can be divided into flat knife, cone knife, ghost teeth three categories! You can break up manpower and electric power according to the way you work. But no matter what category, my personal advice is to buy the best bean grinder that you can afford. Generally speaking, the bean grinder on the ghost tooth grinder is only suitable for grinding individual coffee, that is, coffee powder with thicker particles. This kind of bean grinder is represented by Japan's Fuji R220 and Taiwan's Yang family's Pegasus 207N, while the high-end ones are American grinder 875 and Fuji R440. Compared with flat knife or cone knife, this kind of grinding plate has an excellent sense of balance and thickness in terms of extraction flavor, but the details are not as accurate as flat knife. (to put it simply, it is like the difference between the gallbladder machine and the stone machine in the stereo.) it is often the first choice for ordinary coffee lovers to make a single bean grinder! The performance of the two bean grinders I recommend below are basically the same! But the price of Fuji is about three times that of Pegasus. However, Fuji is small in size and fine in workmanship, so it is more suitable for a corner of the home. Pegasus is a rough undertaking, living a silly rough, but this image does not affect its good grinding products.

Effect of grain structure on coffee flavor. This is just the extraction process. The core of the extraction process is the higher extraction rate at the high water temperature and the higher extraction rate at the fine point of grinding. So what is the effect of powder structure on extraction? It's nothing but a water block! Cone knife powder under the microscope, the main body of the powder structure will have many protruding outer fulcrum, just like a hedgehog. After a lot of powder particles gather, it is impossible to match them completely because of the external fulcrum. The gap will be larger and the flow of water will pass faster. The flow of water passes faster, so the extraction is relatively low. Ghost tooth powder, ghost tooth grinding out of the powder waist slender, relatively smooth, the coupling between powder and powder will be better. The gap is also small, the flow of water through will be relatively slow, and the extraction will be relatively more. From the taste, the same beans, the same amount of powder, the same water temperature, the same fineness of powder, ghost teeth will have better sweetness. Flat knife grinding powder, than conical knife protruding fulcrum is less, particles into blocks, waist than ghost teeth to be stout. Personally, I think the water resistance of flat knife powder should be the greatest! Ghost tooth powder waist is too thin, peace knife powder compared to the resistance must be less. Then the powder ground by the flat knife, from the structural point of view, the convex fulcrum of the powder particles is less, so the coupling is much better than the cone knife powder. The gap is tighter than the cone knife, the water resistance is larger, and the extraction is more.

A Phillips screwdriver can disassemble the little flying eagle neatly. If the mechanical blind is afraid that it can not be disassembled and installed, as long as each part is dismantled and taken a picture, it can finally be put back together. Brother Bird is introduced in this stupid way. Now when you encounter complicated things, you will still take photos or video recordings to reduce the probability of mistakes.
