Can you use a solar dehydrator to dry food?
Ovens and food dehydrators are the most common methods of drying food, but the sun is just as effective, if not more so. Solar dehydrators can be built fairly easily, with inexpensive materials, as a way to conveniently take advantage of the sunshine for food drying. A solar food dehydrator can be built as small or large as desired.
How does a food dehydrator work?
So there is another significant component at work with dehydrators, air circulation. Air circulation is going to take the moist air that the heating elements pull from the food inside and work with the vents on the dehydrator to push it outside the machine. This keeps the food from reabsorbing the moisture it just lost.
How do dehydrators remove moisture?
The heat of the dehydrator pulls the moisture from the contents inside. The machine achieves this in its own unique way by applying low temperatures and long cooking times. This process is the ultimate moisture removal process as it preserves the nutrients and flavors of the food.
How does a vertical airflow dehydrator work?
The fan then pushes excess moisture to the vents, where it is released outside of the dehydrator. Air may circulate vertically or horizontally — air moved horizontally must have a rear-mounted fan; vertical-airflow dehydrators have fans on the top or bottom of the appliance.

Why is horizontal air movement important in a dehydrator?
Horizontal air movement is great because it eliminates the need to stir around and rotate the trays inside. A dehydrator with horizontal air movement means that there is a fan in the back of the machine and it blows towards the door you open into the machine with.
