Whole grains or seeds of a number of crops are sold in packaged form in the retail trade for direct consumption, for example by germination or grinding into flour at home. Chickpeas, beans, lupins, beans, and flax seeds are mostly used in the preparation of various dishes in their unprocessed form. Roasted confectionery sunflower seeds, pumpkin seeds, and peanuts are also directly consumed. It goes without saying that such grains should have the best consumer properties and the best presentation, which is achieved by thoroughly cleaning them, separating them into certain fractions by size, hulling speed, surface condition and colour.
