Generally, the moisture of the grains is controlled below safe moisture, so that the grains can be prevented from mildewing.

The traditional method for reducing the moisture of the grains is a spontaneous combustion airing method. In a grain main production area, due to the large yield and the insufficient airing field, the moisture of grains purchased in a grain depot often exceeds safe moisture, so that the grains in the grain depot are a main factor causing the grain mildew, particularly in the grain purchasing period, the grains catch up to cloudy days; in addition, even if the moisture of the grain does not exceed the safe moisture during warehousing, the grain needs to be aired regularly due to spontaneous combustion and moisture regain so as to ensure that the grain does not mildew, and the grain warehoused cannot be aired on time due to the limitation of the airing field of the grain warehouse, so that the grain warehouse mildew is caused.
