Dried distiller's grains have a longer shelf life than wet distiller's grains. The specific storage time will be affected by many factors, including the quality of the drying process, the storage environment after drying, the quality of distiller's grains, and so on.

Usually, dried distiller's grains can be stored for several months to years under proper storage conditions, but it is also necessary to pay close attention to the quality changes of distiller's grains. If the storage time is too long, the nutrients in distiller's grains will gradually lose, and problems such as mold and deterioration will also be faced, thereby reducing its quality and application value.

Therefore, in order to ensure the quality and application effect of distiller's grains, it is recommended to take some effective measures when storing distiller's grains, such as controlling storage temperature and humidity, moisture-proof and insect-proof, etc., to prolong its storage time. At the same time, the quality inspection of distiller's grains should be carried out regularly, such as testing its moisture content and nutritional components, so as to detect and deal with problems in time.
