Types of sawtooth bean grinder recommended by coffee machine and matters needing attention
There are two types of sawtooth grinders: one is a planar sawtooth knife and the other is a three-dimensional conical sawtooth knife.
(1) Planar serrated cutter
The flat machine consists of two annular blades with sharp sawteeth on the circumference. After starting, the coffee beans are brought between the blades and are instantly cut and crushed into fine particles. As far as household appliances are concerned, the flat sawtooth grinder is the closest to a commercial large bean grinder, similar to a bean grinder in a coffee shop.
(2) three-dimensional conical serrated cutter
The tapered bean grinder is composed of two pieces of tapered iron, the surface of which is covered with serrated teeth. The gap between the two pieces of iron is where the coffee beans are ground into powder. The conical serrated cutter produces the lowest friction temperature and can form uniform grinding. Both commercial machines and manual bean grinders use conical serrated cutters.
The bean grinder with higher power has faster grinding speed, the coffee powder stays in the sawtooth room for a shorter time, and can grind the low-temperature coffee. Generally speaking, the power of bean grinder is between 70 watts and 150 watts, and the higher the power, the better.
The grinding effect of some coffee grinders is very poor, and the coffee powder is not fine enough. When brewing espresso, the extraction is insufficient, making the finished product tasteless, so for grinding espresso, special attention should be paid to the precision of the grinder to make sure that it can grind a uniform and meticulous coffee powder, so as to brew a good coffee.
