One of the oldest techniques for preserving food is drying them. The process of drying decreases the moisture content of the food so that it becomes lightweight and easy to store for a long time without refrigeration.
Earlier people used to dry their food with the help of the natural sources like the sun but nowadays with the invention of the innovative technologies like dehydrators, the method of food preservation has revolutionized. With the help of the food dehydrators, you can make ample of dried foods like fruit chips, fruit leathers, dried jerky, etc.
Sun drying and drying with dehydrators are two different modes that used for drying the food. But what is the difference between dehydrator and sun drying?
In the below article, we will make a discussion over the dehydrator vs. sun drying and let you decide that which mode of drying food is beneficial and better for you.

What is Sun Drying and How it Benefits in Drying the Food?
One of the economic and safe methods for preserving food is sun drying, specifically fruits. The foods like vegetables and meats can’t be dehydrated outdoors due to the low acid and sugar content in them.
The fruits possess the high level of acid and sugar content that let them dry quickly and safely under the sun. For drying meats or veggies, the indoor drying methods like using the dehydrator is the best possible option as you can control the humidity and temperature in it.
For the sun drying, you need to have a constant and warm breeze and temperature. At least the temperature of around 85 degrees F is required. When the temperature is high, it will extract the moisture from the fruits whereas the breeze will benefit in dispelling the nearby air. During the sun drying, it is essential to have a low level of humidity, for example, 60% humidity is perfect
It is true that sun drying is a time consuming and slow process in which it is not possible to control the unpredictable weather. Such condition also makes the sun drying a risky option. Sometimes you cannot achieve the right air flow, humidity, and temperature for drying under the sun.
The fruits that are drying under the sun also need protection from the cold air of the night which can increase the moisture again in the fruit. Thus, it is essential to keep the fruits under the shelter for the protection against the night dewdrops.
What do you need for the sun drying?
You need screens and racks for sun drying that will place over the concrete surface or blocks. You should arrange the food in such a way that adequate air can pass between the foods. For avoiding the transfer of earth’s moisture, put the screens or racks over the aluminum sheet or concrete surface. It will aid in increasing the temperature as well.
The racks or screens must make from a high-quality material like Teflon, plastic or stainless steel. The screens made from aluminum, copper or zinc should avoid as these metals can get oxidize and leave the residue over the food for spoilage.
It is also essential to protect the food from the insects and birds while the sun was drying. Thus, for this, you need a cheesecloth covering or one more screen.
Pros and Cons of Sun Drying
Pros:
- You can safely dry fruits under the sun as they possess high sugar and acid content
- It is a cheap method of drying food in which natural source used
- It does not use the fossil fuel energy
- It can work in specific weather condition with the right breeze, humidity, and temperature
Cons:
- You cannot dry vegetables under the sun as they require constant airflow and temperature.
- You have to cover the food in this method for protecting against the pests or insects
- It requires several days for drying
- You can do the sun drying only in daylight
- You have to turn the food after some time for uniform drying
- You have to keep an eye on the sun drying process

What are the Dissimilarities Between the Dehydrator And Sun Drying?
Both methods used for healthily drying food. But still there are some distinctions between the dehydrator and sun drying:
- While drying through the dehydrator, you have complete control over the process of temperature, but in sun drying you cannot control the weather at all.
- In a dehydrator, your food is safe from dirt and rain, whereas in sun drying you have to make some efforts for doing so.
- Dehydrator needs electricity for running whereas in sun drying you need the natural source sun only.
- Sun drying is a cheaper method in comparison to the dehydrator drying process.
- Sun drying takes more time (several days) than drying in the dehydrator (few hours).
- You can only dry fruits correctly in the sun whereas, in the dehydrator, you can dehydrate meat, fruits, veggies, and many more.
- You have to turn the fruits under the sun for uniform drying whereas in a dehydrator you do not have to do the turning as it uniformly dehydrates the food from all sides.
- Sun drying is done only in daytime whereas the dehydrator drying can do at any time of the day.
