Well-known or not well-known

There are three kinds of cutters in the bean grinder

Which three kinds?

Conical knife, flat knife, and ghost teeth

Next, according to the representative bean grinder, cutter head, grinding state and editor's ability to realize cup test, we will give you a specific analysis.

First, let's talk about the bean grinders represented by the three kinds of cutters.

Conical knife

The representative bean grinder with cone knife is Mazzer superjolly E program-controlled Italian coffee grinder.

Flat knife

The representative of the flat knife bean grinder has appeared in the major cooking competitions in recent years.

And the German Mehdi Mahlkonig EK43 Italian / hand-made commercial coffee bean grinder in major boutique coffee shops.

Ghost tooth

The representative of the ghost tooth is the FUJI ROYAL little Fuji royal electric bean grinder.

It should not be difficult to see

The flat knife is grinded into a sheet.

The ghost teeth grind out more irregular relatively round sections.

What our predecessors summed up:

Cone knife: the coffee bean is ground into particles by grinding, so its shape is mainly block.

Flat knife: coffee beans are ground into particles by cutting, so its shape is mainly flaky.

Ghost teeth: coffee beans are ground into particles in the way of grinding, so their shape is mainly close to circle.

Replacement of bean grinder

I think the right answer may depend on the amount of coffee you grind per hour. Considering that our primary goal is to have the perfect cup of coffee, and the second is to worry about the service life of the cutter head of the bean grinder, I think the steel cutter head will perform better under mild to moderate use conditions. Ceramic cutters do less damage to coffee (flavor) during particularly busy hours of business / production. The bean grinder decides whether to replace or not according to the wear of the cutter head.

The type of cutter head is different, and the shape of grinding is also different, so the flavor extracted is also very different.
