The importance of Italian coffee grinder classification How to adjust the scale

Now there are a lot of coffee powder on the market to sell, many coffee friends are used to buying coffee powder, some are convenient, some are because there is no grinder. In fact, the quality of coffee depends largely on the freshness of the coffee powder. The good imported coffee beans are ground for ten and a half days, even not as good as the freshly ground domestic coffee fragrance, which shows the necessity and importance of coffee grinding.

First of all, a suitable grinder should be able to adjust the thickness to meet the needs of different coffee appliances, because different coffee appliances, the coffee powder required is not the same, the family commonly used coffee appliances, mocha pot and Italian coffee machine requirements of the finest powder, siphon pot followed, American coffee machine (drip coffee pot) and follicular appliances are the coarsest, it is recommended to grind the coffee powder used by mocha pot or Italian coffee machine, take BE8521 grinder as an example, turn the adjusting nut sheet to the tightest, Then reverse 2 circles, at this time the thickness is appropriate, siphon pot reverse 3, American coffee machine reverse 4 circles is appropriate;

Secondly, a good grinding machine should have good corrosion resistance, because coffee is acidic, pay attention to the choice of grinding core metal, good grinding core has good corrosion resistance, general domestic grinding machine using ordinary cast iron movement, relatively easy to rust, and BE series grinding machine grinding core is specially treated with ductile iron, with good corrosion resistance, use more safe;

Italian bean grinder

Italian grinder is divided into cone knife and flat knife.

Cone knife grinder is vertical grinding from top to bottom, the path is longer, its advantage is that you can use a lower speed to achieve a better grinding effect, and produce less heat, you can retain more aroma of coffee powder, the thickness of the demon is more uniform, so that the flavor is more clear, but the price is also a lot more expensive.

Flat knife grinder is a horizontal way of grinding, and grinding path is short, high speed. High-speed grinding will produce more heat and fine powder, which has a greater impact on the flavor of coffee powder.

Hand-operated bean grinder: It is a bean grinder suitable for family use. The principle is to use a fixed cutter head, with a movable cutter head on the axis, to grind coffee beans from coarse to fine. The disadvantage is that the speed is slow. If it is ground quickly, it will generate heat and make the coffee powder lose its original aroma. And most of the hand-operated bean grinders on the market do not have an axis fixing device, resulting in uneven grinding due to axis shaking during grinding.

Household electric bean grinder, commonly known as "bean-cutting machine." The principle is to chop beans with two blades rotating at high speed. Not only will coarse particles appear when chopping, but also a lot of fine powder will be produced. Such uneven coffee powder, even the best coffee beans, can not show its wonderful taste. Moreover, the heat generated during the high-speed rotation process will cause the coffee powder to lose its original aroma.
