Last Updated: 2024/11/08, Italian coffee grinder thickness scale-the thickness of the bean grinder powder determines the direction of adjustment you need (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area. Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

The thickness scale of Italian coffee grinder-the thickness of bean grinder powder

Determine the direction of adjustment you need (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. The traditional method of making espresso (Ristretto) uses a water / flour ratio of 1:1 (i.e. 18 grams of coffee powder is used to make 18 grams of coffee) or 1:2 (i.e. 18 grams of coffee powder is used to make 36 grams of coffee), while a regular espresso uses a water / powder ratio of 1:2 (i.e., "Normale"). Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.

When the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder. The smaller the distance between the blade and the blade, the smaller the coffee beans will be ground into smaller particles. The finer the grinding particles are, the tighter they are, and the more difficult it is for the water to pass through, thus greatly prolonging the extraction time. On the contrary, if the distance between the blades increases, the ground particles will become rougher, the flow of water will be easier to pass through, and the extraction time will be faster. To take a simple example, like stones and fine sand, water flows much faster through stones than fine sand, because there is more space between the stones for the flow of water to pass quickly. Therefore, correct grinding is very important, and the size of particles directly affects the quality of extraction.

Blade is another common coffee grinder, though not the best, but the most common. This type of grinder is designed to grind well, but blade friction may lead to the burning of some coffee beans. In addition, this approach does not provide the best consistency.

Another type is the disc grinder. It is also divided into two different types, namely, flat wheels and cones. Cones are considered to be the best choice to buy. The speed of the disc grinder is slower than that of the blade. The ground coffee beans are fed into a hopper and brewed into coffee. This method can avoid the burning of coffee beans and ensure consistency. But the only drawback of this bean grinder is that it needs more cleaning, which may take some time. But if you want delicious coffee, this is the best coffee grinder you can buy.
