Food dehydrators can be purchased in most department stores and come with their own instructions. But if you're not ready to make that investment there are a simple methods of drying that one can easily do at home. They require more physical and household energy, however. Take a box and line it entirely with thick foil. Place a single lightbulb inside the box but arrange it so it does not touch the box or foil.
Research shows that a long life bulb in a porcelain bulb socket is recommended for safety.
Find a cookie sheet or baking tray that will fit snuggly into the top of the box and blacken the bottom of it with appliance paint. Another, simpler, way to dry indoors is in your oven. Preheat to 145 degrees. Place you produce on baking sheets, with no pieces touching, and put in oven. Leaving oven door open only slightly, reduce the temperature to 120 degrees, then increase it slowly to 140 degrees.
