Selection of bean grinder for coffee production

In general, the Italian commercial bean grinders on the market use disc cutting to grind coffee beans, while domestic bean grinders are mostly blade-based, using the way of chopping beans to grind coffee beans. However, there is a great difference in the uniformity of coffee powder between the two. Although the price of the disc cutting grinder is higher than that of the chopping grinder, it has a great impact on the quality of the brewed coffee, so the disc grinder is the first coffee shop.

Commercial disc cutting bean grinder is divided into two types: disc blade and conical blade according to the form of blade. Most of them are disc blade, that is, upper and lower cutter heads. The lower cutter head rotates by the rotation of the engine. In order to achieve the function of grinding coffee beans. The distance between the upper blade and the lower blade is controlled by rotating the upper blade, thus controlling the thickness of the coffee powder. The general diameter of the flat cutter head is 58mm, 64mm, 75mm and 84mm. The larger the diameter of the cutter head is, the faster the grinding speed is and the more uniform the coffee powder is. The less calories you generate, the better you can retain the aroma of coffee. As a result, the coffee product is more stable and the aroma of coffee is better.

Another thing to pay attention to, the distance between the upper and lower cutterhead of the bean grinder is adjusted to the thickness you want, according to the actual situation every day. Some coffee grinding bean opportunity counterweight way, to reduce the vibration of the grinding machine, so that the coffee powder is more uniform, so the heavier coffee grinder is better than the light one under the same circumstances. An excellent bean grinder is a strong guarantee for the production of high-quality coffee.
