Saving seed for later use or longer term storage requires the removal of most, but not all, of the moisture present in the seed.

Careful drying of seed slows the rate of deterioration, helps more seed remain viable, and can prevent the growth of fungus or production of toxins.

To improve seed processing operations at AVRDC’s Regional Center for Africa (RCA) in Tanzania, two seed dryers were constructed by a local carpenter from plans designed by genetic resources scientist Marilyn Belarmino and other RCA staff.

All materials were purchased locally.

The bottom of the drawers in each dryer are made from nylon mesh supported at the bottom with wire mesh.
 
The dryers are powered by small motors. As cool air flows over the seed, the seed dries gradually and thoroughly.

Using the dryers prevents accidental mixing of seed, and prevents contamination and impurities caused by dust, a common problem when seed is dried on the ground.
