Farmers are cautioned that freezing stored wet grain can create many additional storage problems and end in substantial financial losses. There are not any advantages to freezing grain.

Freezing your stored wet grain may delay moisture damage initially but provides a really significant drying problem when ambient temperatures start to increase in the spring. Frozen wet grain will need intensive management because as soon as the grain is hit with warm air it’ll start to clump together creating air flow problems within the bin and potentially clogging grain moving systems.

Increasing the temperature of frozen wet grain during the spring would require continuous heating and aeration until the grain mass reaches ambient temperatures. Shutting off the fans can end in spoilage, as uneven heating and moisture migration throughout the grain mass will occur rapidly.

Thawing or warming frozen wet grain can therefore be quite a challenge. Cold grain against sun-warmed bin walls is subject to crusting and spoilage. Crusting is a sign that moisture is moving from warmer to cooler zones dropping the water holding capacity of the air.

Grain is a superb insulator so it’ll take significant warmth and air flow rates to increase the temperature of frozen wet  grain within the interior of the grain mass – aeration fans alone will likely be insufficient.

Frozen wet grain will likely cause air vents and roof access covers to ice up thanks to condensation because the warm spring sun heats the bin roof. This will create a dangerous pressure seal on the bin which may damage the bin seals and bin roof. Turning on aeration fans during this situation can cause the roof and bin sides to bulge and deform ruining the grain bin’s structural integrity.
