Classification Of Electric Coffee Grinder

The types of Electric Coffee Grinders are divided as follows:
1. Coffee extraction methods can be divided into two categories: single-product coffee bean grinder and Italian coffee bean grinder;
2, the structure of the grinding disc can be divided into three categories: flat knife, taper knife, ghost teeth;
3, the working mode can be divided into hand grinding and electric.
Grinding machine grinding disc difference: generally can be divided into flat knife, taper knife and ghost teeth three categories, grinding disc determines the main performance of the grinding machine, but also determines the price of the grinding machine.

1. Flat knife
How it works: A metal blade, mounted on a Motor rotor, turns the upper and lower cutters when the motor starts, creating a cutting motion that cuts the beans into crushed particles.
Suitable for: all kinds of single coffee.
Advantages: accurate design positioning, product quality and grinding machine grade and disc diameter is directly proportional.

2. Taper knife
Principle: It is produced by extrusion grinding between two conical knives, a moving wheel and a stationary contact surface, the particles do not need to be pushed out of the coffee.
Suitable for: Espresso, Turkish coffee, French press coffee.
Advantages: Compared with the flat knife grinder, the cone knife grinders the particles more evenly, produces less fine powder, is not easy to produce impurity and astringency, and improves the sense of hierarchy of coffee flavor.

3. Ghost teeth
How it works: The coffee beans are mainly ground into granules in the way of grinding so that the shape of the beans is relatively close to the oval shape. Suitable for: Single coffee, or if you want to get a coarser coffee powder.
Advantages: A better sense of balance and thickness, more uniform Coffee Grinder degree, compared with flat and taper knife cleaner and fuller.adaptability, for a variety of coffee extraction equipment is better.
