What is Solar Food Dryer?

The traditional methods of drying food are soaking the food in the open air in the sun. This method, called sun drying, is effective for small amounts of food. The space needed for sun drying expands with the amount of food, and the food easily loses its contamination (purity) as it is placed outdoors. Therefore, one of the main reasons why sun drying is not easily accomplished with larger quantities of food is that monitoring and overview becomes increasingly difficult with increasing food quantities. Unlike sun drying, where food is exposed directly to the sun, the sun drying method uses indirect solar radiation. The principle of the solar drying technique is to collect solar energy by heating the air volume in the solar collectors and to transmit the hot air from the collector to the drying chamber, which is an attached enclosure.
A solar food dehydrator is used to dry foods such as fruits and vegetables so that they can be stored for a long time. Working with solar energy makes these food dehydrators efficient and inexpensive.
Since you use solar energy in a natural way with SolarBox product drying systems, you prevent your products from being exposed to undesirable effects such as burning and scorching.


In this closed system consisting of a solar collector and drying chamber, drying is more hygienic as the product is not directly exposed to the environment and there is no secondary contamination of the products by rain, dust, insects, rodents, or birds.
Products are dried only with hot air.
Solar radiation (sunlight) has no direct effect on the product. Solar energy produces hot air in solar collectors. Increasing the temperature in a given volume of air reduces the relative air humidity and increases the water absorption capacity of the air.
A steady stream of hot air into the drying chamber circulating through and over the product parts results in continuous and efficient dehydration.

How Does the Solar Food Dryer Work?

Solar-powered food dehydrator works exactly the same as an electric dehydrator. Food is prepared by slicing or chopping and then placed on trays or layers of cheesecloth placed inside the dehydrator. Instead of using electricity to direct warm air to dry food, a solar food dehydrator uses free, renewable energy from the sun. Depending on the design and size of your solar food dehydrator, the food inside will usually be ready within two days. You can use these sun dryers any time of the year, even in the snow, as long as there is the sun.

After removing the moisture from the food with our solar drying systems, it can be safely stored for months before use.

How Does Enge Solarbox
Food Dryer Work?

After the prepared products are placed in the drying room, the system is activated.
100% fresh and hot air obtained from solar energy is passed through Solarbox heat panels and is protected from external factors thanks to the filter. Fresh and hot air is distributed homogeneously in the drying room with air channels that do not form bacteria.
- The moisture and water vapor formed in the drying room and originating from the product are completely discharged by EGK devices.
-With this system, you can get products every day of the year.
- Production time may vary from 8 to 24 hours depending on the product and climatic conditions.
-According to the region and climatic conditions, Enge SolarBox heat panels can heat the outside air up to 65 °C.
-Enge SolarBox Drying Technology, which is the new and hybrid solution we developed with solar energy used in the natural drying of all foods, is the most efficient and economical drying system of recent years.

Which Foods Are Suitable for Drying?

Almost any fruit, vegetable or herb can be successfully dried. The food is sliced into thin strips or slices, taking care not to overlap inside the dehydrator.

Common Benefits of Solar Powered Solar Dryers

Technology provides various socio-economic benefits. One of the main problems facing developing countries today is the issue of food security. A solar food dehydrator can improve food safety by allowing food to be stored long after drying compared to non-dried food.

A solar dryer can save fuel and electricity when it replaces dryer variants that require an external energy source in the form of electricity or fossil fuels. In addition, solar food dryers shorten drying times compared to drying in the sun. While dryers powered by fossil fuel or electricity may provide certain benefits (more consistent airflow and higher temperatures), the financial barriers these technologies provide can be too high for marginal farmers. For example, electricity may not be available or maybe very expensive, and fossil fuel-powered drying can incur large initial and operating costs. With solar drying, these engineering applications that shorten the processing times and reduce your expenses in your drying facilities will help you to reduce your expenses in the short term. Solar drying systems are installed with Enge's engineering experience based on many years.


Fruit, vegetables, and meat dried in sun dryers are better in terms of quality and hygiene than fruit, vegetables, and meat dried under sun-drying conditions. As mentioned, contamination of foods is prevented or minimized thanks to the closed system design. Additionally, food is not vulnerable to rain and dust compared to the open system design of sun drying.

In rural areas where farmers grow fruit and vegetables without proper food drying facilities, farmers must sell the food in the market shortly after harvest. When food production is high, farmers have to sell food at a low price to avoid depreciation of food through spoilage. Therefore, the solar food dehydrator can avoid the financial losses that farmers face in these situations. Dried foods can be stored longer and retain their quality longer. Also, dried fruit and vegetables can be sold as differentiated products, possibly increasing their market value. For example, cured meat can be processed into a variety of different products.

Drying food reduces its volume. Therefore, combined with longer storage times, food is more easily transported after drying, potentially opening up additional markets to the food producer.
