After the grain is harvested, we should try to use the windmill sieving method to remove the impurities mixed in the grain and minimize the impurities such as the grass seeds, fragment of grain, dried grain, soil particle aggregate chips and pests existed in grain. That is due to the complete and healthy grain have strong vitality and it has certain resistance to insect and mildew, while the broken and unhealthy grain don’t have the resistance, and it is easy to absorb moisture, breed pests and grow mildew, so the environment of much broken grain and impurities, high water content will cause a favorable environment for molding and growing worms, and the healthy clean grain will reduce or avoid these factors which are counting against storage.
