Safely Manage Tough and Damp Grain at Harvest With the Fast Dry Technique Developed by Wall Grain
What does it mean to Fast Dry my grain?
Fast drying grain is a technique developed by Wall Grain to effectively and quickly dry down your damp or tough grain as soon as it enters the bin.
Why should I Fast Dry my grain?
One major problem with a wet harvest is having to figure out how to safely store your grain. Storing tough and damp grain is not recommended for periods longer than even a couple of weeks (temperature & moisture dependent).
Fast Drying your grain as soon as the grain hits the bin is not only efficient but can save you a lot of $ in potential storage losses during the fall and winter months.
For more information on the problems involved in storing wet grain refer to our last blog post Storing Wet Grain at Harvest.
How do I Fast Dry my tough or damp grain after harvest?
To fast dry grain, Wall Grain recommends:
- Flat bottom bins with bin sweeps
- Aerated floors (100% coverage)
Flat bottom bins equipped with full aerated floors provides more drying area to create an even drying front within the bin. Much more drying area than a hopper bottom bin.
Fans are used to establish and promote a drying front within the bin. Fans running without heat are effective for establishing a drying front within the bin if the relative humidity is low enough and air temperature is high enough to create a lower Equilibrium Moisture Content (EMC) than the current EMC of the grain in the bin.
If the outside temperature and humidity are not optimal you need to start the burners in order to generate the heat required to dry down the stored crop to the appropriate EMC.
What is Equilibrium Moisture Content? And why is it IMPORTANT to know when storing my grain?
EMC is the moisture content of the grain at a specific temperature and relative humidity. EMC varies by crop type (cereals vs oilseed, etc.). By understanding the EMC value for your crop at a given time and under current temperature and humidity levels, you can save a lot of money and time by drying your grain down to the point it needs to be for safe storage and not any further. This reduces costs and reduces the risk of shrinkage, a state of the crop where it deteriorates in quality due to excessively low moisture levels.
