? Modern roller mill flour mill is the use of centrifugal cast steel grinding rollers fine grinding, the use of arranged orderly steel teeth rollers or glossy grinding rollers for milling, and the mill's running speed, high temperature, the speed of 500 to 800 rpm, the temperature is 120 degrees Celsius, due to the steel rollers grinding is too strong, the mill temperature is too high, resulting in a greater loss of proteins and other nutrients in the flour, wheat germ in the loss of the natural flavor of the wheat embryo, the starch chain is damaged. More, the starch chain is damaged, the prominent manifestation of the dough's stability time is low, forcing manufacturers to add a variety of additives.
2, due to the stone milling flour mill contains a large number of carotene and dietary fiber, so the stone milling flour is natural white and slightly yellow.
The flour processed by the roller mill flour mill caters to people's wrong dietary habits of eating the whiter the better, adding additives such as whitening agents, gluten-strengthening agents (benzoyl peroxide and potassium bromate industrial chemicals). So the flour appears very white.
? Stone mill flour mill is the method of using two hard grinding disk surfaces engraved with teeth and grooves to cut and friction on the material to make the material broken. This main method mainly relies on the positive pressure of the grinding disk and the friction of the relative motion of the two grinding disks to act on the material particles to achieve crushing.

? Roller mill flour mill is the use of two smooth surface pressure rollers with the same rotational speed relative rotation, the material particles sandwiched between the two pressure rollers for extrusion and make the method of crushing.
