Your drying strategy will depend on whether you’re growing sunflowers for crop yield or in a personal garden. Today, we’ll focus on a large harvest. The time required to dry the crop is going to be influenced by the moisture content, temperature of the drying room, and the humidity to which your harvest is exposed. Variances in any of these factors will change the dry rate. For example, raising the temperature a few degrees will cause the moisture level of your sunflowers to decline, thereby shortening the time needed to dry them. Below, I’ll provide a few helpful tips that you can use when drying your next crop.
#1 – Use A Moisture Meter
You’ll need to invest in a reliable moisture meter. If you’re a hobby grower, you won’t need one. But, assuming you’re harvesting a large crop, a meter is essential for measuring the level of moisture contained in the seeds. It’s only by taking this measurement that you’ll be able to accurately judge the approximate drying period. If you’re already an experienced grower, you’ll probably already own one. If not, plan on spending $200 or more.
#2 – Don’t Overcompensate
If you grow other crops that need to be dried (for example, corn and grain varieties), take care not to over-dry your sunflowers. Compared with a lot of other crops, lower quantities of moisture need to be removed from them. At any given temperature, it’s easy to overdo it. If you’ve harvested your crop early to prevent bird and disease damage, they’re going to have a higher moisture content and require more time to dry. Even so, keep a close eye on the dryer and take several moisture measurements with the meter. (more…)
