Which is more versatile, a solar dehydrator or a solar oven? Many solar ovens are sold with the promise that, besides cooking food by the energy of the sun, you can also dehydrate food. Here is the secret of how to do both.
The debate between the versatility of solar dehydrators and solar ovens is ongoing. While many solar ovens are marketed with the claim that they can also dehydrate food, the reality is more nuanced. This article delves into the practicalities of using solar ovens for both cooking and dehydrating, based on personal experience and scientific data.
Having owned two solar Sun Ovens for nearly two years, I've cooked a variety of dishes that I would typically prepare in a conventional oven. One of the most striking benefits of solar cooking is the enhanced flavor and moisture retention in the food. Unlike traditional cooking methods, solar cooking preserves the nutritional value of the food, making it a healthier option.
One of the primary challenges of using a solar oven for dehydrating food is temperature control. Solar ovens generally maintain a constant temperature of 300-350°F, which is ideal for cooking but not for dehydrating. Dehydration requires temperatures below 200°F. The lack of a thermostat in solar ovens makes it difficult to maintain the low, consistent temperatures needed for effective dehydration.
Another significant drawback is the dependency on sunlight. No sun means no cooking or dehydrating. Additionally, the sun's position changes throughout the day, requiring constant adjustment of the oven's reflectors to maintain the desired temperature.
Last summer, I attempted to dehydrate fruits and vegetables using my solar oven. Unfortunately, the results were less than satisfactory. The high temperatures caused the food to cook rather than dry, leading to baked, rather than dehydrated, produce. For instance, baked mango or papaya is far from appetizing.
To address these issues, I experimented with various techniques, such as propping open the oven door to regulate the temperature. However, this led to uneven heat distribution and inconsistent results. I realized that a fan was needed to circulate the warm air evenly around the food.
To maintain the energy efficiency of the solar oven, I used a DC fan powered by a solar panel. I placed the fan on the tray, propped open the glass door by 3/8 of an inch, and used PVC spacers to stack drying racks. This setup allowed the hottest air to escape while the fan circulated the remaining warm air evenly around the food.
For those interested in trying this at home, detailed instructions and free recipes can be found on Sun Oven Chef. This kit is compatible with most solar ovens on the market.
While solar ovens are excellent for cooking, they are not ideally suited for dehydrating food due to temperature control issues and dependency on sunlight. However, with some modifications, such as adding a solar-powered fan, it is possible to use a solar oven for dehydration. For those looking to explore this further, building a solar oven dehydrator kit can be a rewarding project.
Remember, while dehydrating food, it's crucial to stay hydrated yourself. Drink plenty of clean, healthy water daily.

Be Concerned, Be Very Concerned
Water serves three major purposes in our bodies. 1. It controls body temperature. 2. It is the solvent for the foods we eat, carrying the nutrients to every cell of our body. 3. Water replaces bodily fluids such as blood plasma, lymph, digestive juices, bile etc. and washes and bathes every cell, flushing and carrying away waste materials and toxic poisons. If water is so vital to our health and existence, shouldn't we drink the healthiest water possible?
