What is the difference between hand-operated bean grinder and electric one?
Basic knowledge of hand mill
1.4 use skills
Hand grinder gives everyone the impression that it is very tired to grind. At present, coffee beans are more popular in the domestic market for medium and deep roasting, and beans are still easy to grind. You can try to sit on the stool, put the bean grinder on your knee, and then start grinding. I usually use this method. It's easy to say, and you don't have to press down hard.
1.5 Clean
After each use, try to clean the residual powder in the grinding core, bean warehouse, powder cartridge and powder cartridge. When it is not clean, you can blow it in the dishwashing pool with your eyes closed. If it is not used for a long time or for a long time, it can be cleaned with warm water again, if the grinding core is metal, it can not be washed with water.
two。 Buy hand bean grinder
Coffee beans have been determined, and roasting technology is the most important factor in determining the quality of a cup of coffee. When buying a hand bean grinder, the grinding core must be ceramic, and the price can be purchased according to everyone's own economic strength.
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 above 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 cannot 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.
