Conditions for flour preservation:
1, Humidity: Flour has strong adsorption. If the humidity of the surrounding environment where the flour is stored is higher than that of the flour itself, the flour will absorb a lot of water until it is in balance with the surrounding humidity. Therefore, the environment for storing flour must be kept dry and ventilated.
2. Proper temperature can prolong the shelf life. Too high or too low temperature is not good for stored flour.
3, location: suitable for placing on a plastic tray.
