Coffee grinder Introduction Hand grinder
For more than 100 years, the design of the hand-operated bean grinder has hardly changed, and even the latest models tend to be classical and elegant. This kind of bean grinder needs to rotate the rocker by hand, turn the iron sharpening knife inside, crush the coffee beans into a fine powder and drop them in the box below. Strictly speaking, the internal sharpening knife is not a knife, because it does not have a sharp blade or sawtooth, but a tapered grinding iron with an angle. It grinds the coffee beans by rolling, which is similar to the ancient mortar and pestle, and can best retain the aroma of the coffee.
Although it is a bit hard to use a hand bean grinder, and the speed is not fast, it can grind coffee powder with uniform particles, and the friction temperature during grinding is the lowest, so it is not easy to destroy.
The delicious coffee is very suitable for drip filtration and drip brewing. In addition, the hand-held bean grinder makes the least noise and has always been a favorite of coffee brewers.
The hand-operated bean grinder usually has a ring-shaped knob between the rocker and the main body, which can grind down to produce finer coffee powder. this bean grinder can grind coffee powder of medium to fine size, but it is impossible to grind very fine powder. so it's not suitable for the grinding of espresso powder.
