When grinding beans, the size of the powder depends on the way it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. Sixth, in terms of the actual way of cooking, it takes a very short time for the ESPRESSO machine to make coffee, so the grinding is the finest, and the coffee powder is as fine as flour; it takes more than a minute to cook coffee in the "plug wind" way, and the coffee powder belongs to medium-sized grinding; American filter coffee takes a long time to make, so the coffee powder is the thickest, one by one like Beijing grains on a shell beach. Grinding coffee powder with appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in over-extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

There are different brands and types of bean grinders for grinding coffee, and the ideal one is a grinder that can adjust the thickness of the beans. When grinding with a bean grinder, do not grind too much at one time, just enough powder for one time, because the longer the bean grinder is used at one time, the easier it is to get hot, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the cooked coffee.

Coffee beans contain oil, so the bean grinder must be cleaned after grinding, otherwise the grease will be fouled and will smell stale after a long time, and even the most advanced beans will be ground into a strange-smelling powder. After each use of the bean grinder, be sure to wipe the blade table with the wet market and clean the plastic top cover with warm hot water. But for the American popular flavored coffee, the added flavor is strong and strong, and it will last for a long time. It is best to put two tablespoons of white Jing sugar in and beat it before cleaning. Of course, it is better for a grinder to grind only the same kind of beans, so there is no problem of mixing.

1) Surface area of grindstone

2) sharpness of grindstone

3) the precision of the gap between the two grindstones can be kept fixed during grinding.

(note that in household products, compared with the surface area of each coffee bean exposed to the grinder, the conical grinder is larger than the platform grinder.)

Generally speaking, one grinding blade is fixed (called stator), and the other grinding blade is rotated (called rotor). In most designs, the thickness of the grinding particles is adjusted by moving the stator closer to the rotor. This is usually (but not always) done by adjusting a screw to move the bearing bracket that carries the grinding disc (usually controlling the upper grinding disc). The quality, weight and accuracy of the bracket carrying the grinding piece determine the quality of the bean grinder.
