The beauty of coffee is that you can participate in the last mile before you drink it.

Even if it is tasting in the end, it is more fun to grind than tea and more fun to grind and brew than wine.

But many people are used to buying ready-made powder or asking the store to grind it into a large bag at a time and use it slowly at home.

In fact, the best way is to grind and cook, or grind a small amount and use it quickly.

Since coffee can bring so much fun, we have to know how important the bean grinder is.

Why not just buy ready-made powder? Do you have to grind so much trouble every time?

The benefits of present grinding

Fresh: the surface area of raw beans in contact with air is much smaller than that of coffee powder, and the fresh time is longer.

Tastes better: the present mill will make the coffee very fresh, because as soon as the coffee is ground into powder, it will begin to oxidize. These aromatic substances will dissipate in 15-20 minutes. So why not leave these good things in your coffee cup?

You can adjust the grinding thickness of coffee beans.

Grinding beans will make you feel more professional, like a barista!

If you are convinced, the next question is, what kind of bean grinder should you choose? Do you want to choose a cheaper blade or a more exquisite one?

What's the difference between these two kinds of bean grinders?

What is a blade bean grinder? How does it work?

Basically, the blade uses a piece of metal to rotate the chopped beans electrically. You can roughly control the size of the powder through the speed of the blade. Imagine putting the coffee beans on the chopping board and chopping them with a knife.

Advantages of blade type

Simple adjustment, basic grinding function, cheap

Blade defect

1. Imprecise grinding quality and unstable cooking results: because the blade grinding machine grinds all beans at the same time, the size of the coffee powder may be uneven, because the blade will cut up the coffee beans aimlessly, which means that the finished powder will have coarse particles, which will lead to insufficient extraction, and there will also be powders that are too chopped to lead to over-extraction.

two。 The fine powder mentioned in the first point can block the filter of the coffee machine or cup, or directly penetrate the filter so that there are fine coffee grounds in the cup.

3. The biggest disadvantage of the knife cutter is the heat produced during grinding-this heat can cause the coffee to taste scorched and bitter, especially if you grind it very fine, resulting in longer contact between the beans and the blade.

What is a knife plate type bean grinder? How does it work?

Grind the coffee beans in a quiet and moving way through two metal cutters. The distance between the cutters controls the thickness of the grinding. by adjusting the spacing, the grinding particles are small enough to pass through the cutters. imagine cutting the coffee beans into thin slices.

Cutterhead advantage

-the roughness and fineness of the grinding is the same, the coffee is more uniform and the extracted coffee has high flavor stability.

Since grinding does not produce a large amount of heat, the aroma and grease of coffee can be preserved.

-accurate and finer grinding. The cone knife is suitable for fine-ground espresso and Turkish coffee, as well as coarse-ground French filter pots.

The knife head grinder can also be divided into two main types:

Round knife / flat knife bean grinder (Flat Burr):

The cutter head is smaller-it is also a more economical option. The cutter head will make a lot of noise because of its rapid rotation, and the faster it rotates, the lower the grinding quality (the more the knife head will heat the grinding).

Cone knife bean grinder (Conical Burr):

The author thinks that it is the best type of bean grinder, and the rotation speed of the cutter head is slower than that of the flat knife, which is not only quieter during grinding, but also more stable. It is suitable for deep baking with high grinding oil or shallow baking with aroma type, because the grinding quality is high and will not block the filter. And the larger cutter head also helps to stabilize the heat dissipation.

How to maintain the knife head grinder?

-cleaning the bean grinder regularly, especially after grinding spiced coffee beans, is as simple as that! The knife plate bean grinder takes care of everything.

If you must not have only a blade grinder available, remember to pay attention to the following things:

1. Empty all the powder after each grinding, especially the powder accumulated under the blade.

two。 The grinding time should not exceed 15 seconds-avoid a large amount of heat from cutting.

3. Shake the bean grinder during grinding so that the machine can cut coffee beans more evenly.
