Answer:
Harvesting, threshing, and winnowing are the three processes involved in preparing wheat for milling.
Harvesting is the process of cutting the mature wheat plants and gathering the wheat heads. Once the wheat heads are collected, they are taken to the threshing floor, which is a large, flat surface where threshing takes place.
Threshing is the process of separating the grain from the wheat heads. In traditional threshing, the wheat heads are beaten with flails or crushed by the hooves of cattle or horses. Modern threshing machines separate the grain from the chaff using mechanical processes.
After threshing, the mixture of wheat grain and chaff is taken to the winnowing floor. Winnowing is the process of separating the grain from the chaff. The mixture is thrown into the air, and the wind blows away the lighter chaff, leaving only the heavier grain behind.
Once the wheat has been harvested, threshed, and winnowed, it is ready for milling. The wheat is ground into flour by passing it through a series of rollers that crush and grind the grain. The flour can then be used to make a variety of products, including bread, pasta, and pastries.
