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.

在石磨機中，兩個對輥相對運動，就能把小麥碾磨成面粉，在此之前，小麥還有一個脫皮工藝，是把小麥的表皮去掉的過程，表皮去掉后，對輥就把這些麥仁直接碾壓成面粉。

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.

面粉的顆粒，與對輥的齒數(shù)多少有直接關系，齒數(shù)越多，加工出來的面粉也就越細膩，齒數(shù)越少，加工出來的面粉就越粗糙，但是，粗糙的面粉卻有濃郁的麥香味，只是做出面食來顏色不太好看，略微地發(fā)黃或灰色。

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.

這不是臟東西，而是麥芽里胡蘿卜素的作用。除此之外，面粉機械的加工速度對面粉質量也有一定的影響，速度越低，營養(yǎng)物質越不易被破壞，面粉越有營養(yǎng)。

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.
