What is a solar dryer and how does it work?
A solar dryer is an appliance consisting of two parts: an air collector and a dryer.
The air collector traps the sun's radiation and converts it into heat. A fan circulates the hot air through the dryer.
The hot air eliminates a large proportion of the moisture content from the produce laid out in the dryer, dehydrating and preserving it.
What are solar dryers used for?
Solar dryers are used to dehydrate agricultural products such as fruit (apricots, grapes, peaches, plums, figs, etc.), vegetables (niora, tomatoes, onions, etc.) and even meat, for preservation purposes.
What are the advantages of solar dryers over traditional drying methods?
In contrast to traditional drying methods, solar dryers:
enable fast, controlled dehydration of produce
yield a better-quality dried product
protect the produce from insects, animals, dust, etc. during drying
