the central core. As this cooling system migrates, it gathers moisture and warmth that create a pocket of humid and warmer air at the top of the central grain core where spoilage and heating can begin.

Due to continuously declining outside air temperatures, it is wise to aerate repeatedly until the whole canola bin is between 0 and 50 C.
