Unit 2.3: Grain Drying

Learning Objectives

Learn about the different types of dryers and how they work.
Learn what methods can be used with each dryer type to reduce energy use.
Learn about the grain quality advantages of in-bin cooling and dryeration.

Background
To save on energy costs, it is best to avoid drying whenever possible. Instead of drying, consider that:
• high moisture storage of grain can be used for livestock feed that will be fed out by spring;
• late harvested corn can be stored in a bin with aeration at moisture contents up to about 20 percent as long as the corn temperature can be kept near freezing;
• corn can be ensiled at moisture contents of 25 to 35 percent. Air must be kept out of the ensiled high moisture corn to prevent spoilage.
