Why do some mills produce hot flour and some cool?

1, grinding method: different grinding methods may lead to different noodle temperatures. The traditional stone grinding process has a lower surface temperature due to slower speed and less friction. While modern machine grinding may lead to higher surface temperature due to higher friction.

2, the moisture content of the flour: the moisture content of the flour also has an effect on the temperature when grinding. If the moisture content of the flour is high, the friction generated during milling is less, and the pasta temperature may be lower. Conversely, if the flour is drier, the friction during milling is higher and the pasta temperature may be higher.
