Increase the moisture content of ordinary corn grain to around 20%, aiming for better gelatinization during the steaming process. A moisture-retaining bin typically consists of 2-4 units, sufficient for the continuous 24-hour production cycle of the corn flaking equipment. The corn is added with water into the bin, where it is soaked for 24 hours, reaching a moisture content of around 20%. The quality of the finished corn flake products obtained from soaked and unsoaked corn differs significantly after processing.
