Quick Answer
You can dehydrate vegetables alongside fruits in solar units, but it's essential to consider their individual moisture levels and dehydration times. Most solar dehydrators can handle a mix of foods, but you may need to prioritize one type based on its higher moisture content.
Choosing Compatible Vegetables
When selecting vegetables for dehydration alongside fruits, focus on those with lower moisture levels, such as leafy greens, bell peppers, and cucumbers. These can be dehydrated alongside fruits like apples, berries, or citrus, as they also have relatively low moisture content. Vegetables with higher moisture levels, such as tomatoes or squash, may require longer dehydration times and may not be the best choice for a mixed load.
Temperature Control and Airflow
Maintaining a consistent temperature between 135°F and 155°F (57°C to 68°C) is crucial for efficient dehydration. A well-designed solar dehydrator should provide adequate airflow to prevent temperature fluctuations and ensure even drying. When dehydrating a mix of vegetables and fruits, you may need to adjust the airflow or temperature settings to accommodate the varying moisture levels and dehydration times of each food type.
Dehydration Time and Monitoring
Dehydration times will vary depending on the specific foods you’re processing. As a general rule, vegetables with higher moisture levels will take longer to dry than fruits. For example, a solar dehydrator can dry sliced apples in 6 to 8 hours, while sliced cucumbers may take 8 to 12 hours. It’s essential to monitor the dehydration process regularly, checking for texture, color, and moisture levels to ensure your foods are dehydrated to a safe and suitable level.
