  • Page 13: Eqm Control Instructions

    EQM Control EQM Conditioning Principles 1. Shelf Life Conditioning starts with storage and the desire to keep grain as long as possible without spoilage. Shelf life is determined by grain moisture and storage temperature. This has been well documented by university research and verified by field results.
  • Page 14 EQM Control EQM Conditioning Principles These principles are important to understand because it affects how grain is dried, the Drying Front, and Equilibrium Moisture (EQM). When water is turned to vapor it takes energy away from the surface of what it is leaving. This is just like when people sweat.
  • Page 15 EQM Control EQM Conditioning Principles Relative humidity and temp create vapor pressure in the air Moisture content and temp create vapor pressure from the kernel The pressure difference drives moisture either into the air or into the kernel: • When the pressure in the air is greater, the grain gets wetter •...
  • Page 16 EQM Control EQM Conditioning Principles • The airflow (cfm) is simply how many pounds of air are available to remove water. More airflow means that more pounds of air can carry away more pounds of water per minute. 6. Typical EQM Since the EQM of the air is critical to whether we are removing or adding moisture of the grain, we need to know when the air is right to accomplish the desired Target EQM for the grain.
  • Page 17 EQM Control EQM Conditioning Principles 7. Adding heat Adding a small amount of heat has a dramatic effect on EQM. For example: a typical fall day with 45F temperature and 75% relative humidity produces an EQM of 17% for corn. Just a 3F temperature rise drops the relative humidity to 67% and the EQM to 15.3%.
  • Page 18 EQM Control EQM Conditioning Principles 9. Grain type variances Grain types absorb moisture differently. The same air that would produce 15% moisture for corn would produce 13% for wheat or soybeans. Also the amount of EQM air required to remove moisture in corn is much less than what is required to add the same amount of moisture.
