The so-called flour stone mill, as the name suggests, is the equipment for producing flour. However, you may not understand that although flour machinery is similar, the quality of flour produced is different. So what affects flour? In fact, it is a part of the flour stone mill. The name of this part is the counter roll. Today, I will explain the related knowledge to you.

在石磨机中，两个对辊相对运动，就能把小麦碾磨成面粉，在此之前，小麦还有一个脱皮工艺，是把小麦的表皮去掉的过程，表皮去掉后，对辊就把这些麦仁直接碾压成面粉。

In the stone mill, two pairs of rollers move relative to each other to grind the wheat into flour. Before that, there is a peeling process for wheat, which is the process of removing the skin of the wheat. After the skin is removed, the pair of rollers directly crush the wheat kernel into flour.

面粉的颗粒，与对辊的齿数多少有直接关系，齿数越多，加工出来的面粉也就越细腻，齿数越少，加工出来的面粉就越粗糙，但是，粗糙的面粉却有浓郁的麦香味，只是做出面食来颜色不太好看，略微地发黄或灰色。

The grain size of flour is directly related to the number of teeth on the counter roller. The more teeth, the more delicate the flour will be. The less teeth, the rougher the flour will be. However, the rougher the flour is, the more fragrant it is. It's just that the color of the flour is not very good-looking and slightly yellowish or gray.

这不是脏东西，而是麦芽里胡萝卜素的作用。除此之外，面粉机械的加工速度对面粉质量也有一定的影响，速度越低，营养物质越不易被破坏，面粉越有营养。

It's not dirt, it's the role of carotene in malt. In addition, the processing speed of flour machinery also has a certain impact on the quality of flour. The lower the processing speed, the less likely nutrients are to be destroyed, and the more nutritious flour is.
