Coffee grinder introduce the difference and advantages of flat knife and cone knife grinder how to choose bean grinder

If you drink coffee regularly, you may have heard of the need to use a coffee grinder. But you may not know that there are many possibilities when it comes to different types of coffee grinders.

When comparing a cutter head grinder with a blade grinder, the difference depends on what you want from a cup of coffee.

Although all this may seem trivial, it is important to understand that improperly ground coffee beans can lead to a cup of shoddy coffee.

Most coffee lovers will tell you that the knife plate grinder is much superior in terms of uniform grinding size and flavor. Although it is more expensive than the blade bean grinder, it has been well received because of its consistency, quality and the whole.

So how does the knife plate grinder work?

The knife head grinder is composed of two rotating cutters, and the coffee is ground between the two rotating cutters. Beans are crushed between a moving grinding wheel and an immovable surface.

At present, there are two main types of coffee grinders on the market, one is a flat knife and the other is a cone knife. Although both of them are excellent and can produce consistent and high quality grinding, you should understand the difference between them to make sure which one is more suitable for you. Let's take a look at their respective advantages.

The advantages of flat knives

More consistent grinding size

Allow larger espresso to be made

Advantages of tapered cutterhead

Dual mode (two sizes or "inconsistent" grinding) is actually the key to espresso.

Faster grinding speed

Due to design reasons, fewer coffee grounds are trapped in the grinder, thus reducing waste and cleaning.

The price is cheaper.

For the electric grinder, it can rotate at a lower speed, thus reducing heat and noise.

Conical cutter head grinder is the industry standard of cutter head grinder. They use tapered center cutters and outer serrated cutters to help produce ground coffee over and over again. Moreover, its design is naturally energy-saving and heat-resistant, making it an excellent choice for professional and family baristas.

However, the tapered cutter head does not produce evenly ground coffee, and if you put it under a microscope, you will notice a difference in the size of the coffee beans in the mixture. Although this will not affect the overall taste of your coffee, some people do prefer to use a flat bean grinder to make espresso. In fact, the flat cutter set became popular after it was launched during the 2013 World Barista Championships.

The flat cutter head grinder has two circular cutters, which are opposite to each other and have very sharp edges. This design allows beans to stay between cutters until they are perfectly (and symmetrically) ground, rather than conical cutters that allow beans to shoot out and maintain some integrity. When all coffee or espresso powder is of the same size, the taste is very simple, giving baristas more creative space.

However, flat cutters are louder than conical cutters and consume more energy and heat during grinding, making them less suitable for commercial or even household use. But when precision is needed, the flat cutterhead is a better choice.
