A spiral bean chopper (we call it a bean chopper because this machine crushes beans by chopping rather than grinding) not only can't process coffee beans into uniform coffee powder, but also generates a lot of heat in the process of chopping. Coffee powder accelerates the oxidation process when heated. The flavor will also be taken away! In addition, under the first principle of successful extraction of boutique coffee (uniform extraction), because the coffee powder particles chopped by the chopping machine are coarse and fine, it will also lead to the failure of coffee extraction! The most direct is excessive extraction, or insufficient extraction! Under-extracted coffee will be sour and numb, while over-extracted coffee will be too bitter.

The coffee machine adopts hand-held grinding method, which is very ancient and traditional, and exudes a little literary flavor at the same time. In a cozy afternoon, you can enjoy the fun and fragrance of grinding coffee by yourself. The small design can be placed at home and office. The design of the small box is very special. At the same time, the handle is removable and can be placed in a special storage area to take up space.

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.

After some google portable coffee grinder, I learned that the most portable and compelling coffee grinder in the world is Japan's porlex mini. Then, I watched two videos of operation (see video 1 and video 2 attached at the end of this article), which basically met my needs. The coffee machine also designed a super cool fixed sucker, which can be fixed on the table and will not shake left and right when grinding coffee. More stable and easy to operate. If you close the handle when using the coffee machine, it can be fixed to a smooth surface.
