All grains, before going to milling, undergo three stages of cleaning: Having performed all the above stages, the grain is perfect, ready for milling with the Sima stone.
Pre-cleaning: which occurs when the farmers deliver the grain to the mill, exactly before the grain is stored in the cells.
First cleaning: very thorough, tends to exclude from the grains themselves any foreign bodies, straw, soil, stones. This is done through a classical cleaning and a passage in an infrared optical sorter. Unsuitable parts, such as diseased or mismatched grains, are excluded.
Second cleaning: the last stage is that of surface decortication of the caryopsis. This very important stage tends to remove the outermost layer of the grain, allowing customers to come into contact with a product that is ideal from a microbiological point of view.
