Pros and Cons of Sun Drying Food
#1
This is the oldest and most readily available food drying method. It’s free and does not use costly energy from gas or electricity.

However, this is not always available. There are many areas where sunlight is limited. Some may have a good amount of sunlight hours, but the heat is not enough for proper drying of food. Also, it is not accurately predictable on how many days sunlight is available. Food typically needs around 3 to 4 days of drying.

The heat of the sun cannot be controlled, obviously. It may not be emitting enough heat to dry food quickly. If food does not dry in time, the mold may grow, rendering the food unusable. Food may also start to spoil before it is adequately dried under the sun.

For sun-drying to be effective, there should be long hours of direct sun exposure. A 95-degree Fahrenheit temperature is good for 3 to 5 days of food drying. The humidity should also be less than 20%. Otherwise, humidity and shorter periods of direct sun exposure may promote moldy growths.

Pros

Free

No added cost for equipment

No added cost for electricity or gas

Cons

Nearly impossible to control temperature and humidity to ensure consistent drying conditions

The unpredictable result, some may dry well, some may not dry uniformly

Some people just could not pass up the free energy from the sun for drying food. Why spend if there is something for free. To improve results and for greater consistency, people use solar dryers instead. I bought Freeze Dried Fruit Machine and they work great, if you wanna know more information click https://www.gf-machine.com/product/quick...equipment/
