The classification of bean grinder-the grinding size of beans and the taste of coffee have a great influence.

It takes a lot of effort to collect, process and roast a cup of fragrant coffee. You have to wait patiently for one item, but the results need to be grinded. If you want to do a good job, you must first sharpen its tools, and the bean grinder for grinding coffee is also a lesson.

The roasted coffee beans can not be boiled directly, and the coffee beans need to be ground to powder before they can brew the coffee, and the bean grinder plays an important role in this process, so it becomes one of the instruments that must be prepared before making coffee.

Bean grinders are generally divided into hand grinder and electric grinder, but they can be divided into three types according to the blades of the grinder. The introduction is as follows:

First, the spiral type:

Blade: the shape of the blade is like the helix of a helicopter, which is also called "blade shredding".

Principle: use the continuous chopping method to cut up the coffee beans, and the number of blade chopping beans determines the roughness of the coffee powder.

Point:

The grid is low.

Easy to use

High mobility

Missing points:

It is not easy to master the degree of grinding and quality

Poor evenness of coffee powder

Non-fitting mass grinding

Grinding efficiency of blade easy to change shadow

The fragrance of coffee beans by high-speed grinding

It's easy to lose your hands.

Second, cutting sharpening knife:

Blade: it is composed of two sharpening knives with vertical bite mounted on the column, and it is also called "cutting blade".

Principle: using the cutting principle, after the machine is started, when the coffee bean is sharpened, the coffee bean is quickly cut and chopped into powder, while the distance between the grinder determines the roughness of the coffee powder. The closer the distance is, the thicker the powder is, and the thicker the powder is.

Point:

It is easy to "finish and grind"

Good grinding evenness

Can quickly grind a large number of coffee beans

It is not easy to produce friction.

Missing points:

Easy to produce crushed powder

It needs to be cleaned after each grinding.

Third, grinding type knife: can be re-divided into "plane type" and "vertical type", also known as "knife type"

Flat blade: made of slotted environmental blades

Plane principle: using the principle of grinding, when the power source is started, the coffee beans are ground into powder by the blade blade at a very fast speed.

Vertical blade: it is composed of two surfaces with concave and convex surfaces.

Vertical principle: using the principle of grinding coffee beans, the distance between coffee beans determines the coarsening degree of coffee powder, the closer the distance is, the thicker the powder is; on the contrary, the thicker the powder is. Usually the hand-held bean grinder uses a vertical knife.

Point:

The blade "grid" is low

The grinding evenness is excellent.

It is not easy to produce high quality.

It is not easy to film "coffee products"

Missing points:

The grinding efficiency is very slow

Non-fitting mass grinding
