"Wheat pits" is a term often used to describe the small, hard particles or impurities that are found in wheat and other grains. These particles can be difficult to remove and can negatively affect the quality of flour and other grain-based products. There are several synonyms for "wheat pits" that are commonly used, including bran, chaff, and husks. Bran refers to the tough outer layer of the wheat kernel, while chaff is the husk or outer covering that is removed during the threshing process. Husks are the dry outer coverings of seeds or grains that are often removed during the milling process. By removing these particles, flour and other grain products can be produced with greater quality and consistency.
