Because of its grinding disc characteristics, it is easy to grind unevenly.
It is easier to produce a large amount of heat, which aggravates the loss of coffee aroma, which also leads to the easy emission of coffee gas when the hand grinder is grinding.
The efficiency is too low, believe it or not, China Coffee Network believes anyway. This is the biggest problem for China Coffee Network. If I want to make a cup of coffee, if I use 20 grams of coffee beans to grind, the grinding time can be as long as 5 minutes. When shaking, your hands will still get sore. Of course, if you take this as a way of exercise, the hand grinder is quite suitable for you.
The wood base is easy to break, and the grinding plate on the hand bean grinder is fixed on the wood base with screws. After using it for a long time, the hole in the screw will become bigger and bigger, so that the bean grinder can not be used. The solution is to remove the grinding part of the hand bean grinder, and then screw the screw to the base in another place.
