- Solar food dehydrator
Solar food dehydrator
Solar energy is commonly used to produce hot water or electricity for our buildings. Another, lesser known use is for drying food.
Food preservation is a particularly important issue in the third world where cooling systems are scarce and electricity supply unreliable. The use of local, low-cost, renewable energy is an extremely clever solution for these countries.
There are different models of solar dehydrators.
In the first two cases, there is a risk of overheating and food degradation, including the destruction of vitamins A and C by direct sunlight.
This project uses instead the indirect solar dryer technology. Although more complex to build, it offers many advantages:
