Because grain is a good insulator, the center of the grain bin retains heat longer. Moisture migration is caused by differences in grain temperatures within the bin. In the Fall, the cold air on the outside of the bin moves the warmer air inward and eventually upward to the top of the bin. It encounters the cold air at the top of the bin and causes condensation and crusting at the top of the grain. In spring and summer, the opposite is true and condensation and spoilage occur at the bottom of the bin. Temperature monitoring helps maintain even temperature, preventing moisture migration.
Why Use Temperature Monitoring
- Have access to accurate information about storage conditions
- Make sure your aeration systems are energy efficient
- Keeps your grain at the best quality possible
- Alerts you to susceptibility of mold growth due to changing conditions
