Test with a thermometer. This warm temperature also creates the natural air flow through the dryer. Fruits are best dried in a solar dryer. Because fruit has a higher natural acidity than vegetables, less moisture must be removed to be preserved. Put several bricks in the dryer to hold the solar heat longer into evening.
Solar food drying is a good fit with new dehydrofreezing.
Food is partially dried and then stored in the freezer. It retains good color and flavor, uses less freezer space and reconstitutes faster than fully dried foods. Q.
