Freeze-drying fruit at home? Is it possible to freeze-dry fruit at home without expensive special equipment (or get the same dryness otherwise)? Especially I want to get the fruit to the crisp dryness1 of freeze-dried fruit compared to the still slightly damp / soggy dryness of hot-air dried fruit. 

[Edit] Well, turns out, basically no. Freeze-drying not only involves the ability to freeze the food to low temperatures (which can be achieved), but also creating a low pressure environment and controlled heating of the the food in that environment (Not easily achievable or controllable at home). More info from Wikipedia 

1. It should feel absolutely dry to the touch, and crumble / break when handled roughly rather than stretch / bend.
Assuming you have a frost-free freezer (which dehumidifies the cold air), I'd experiment by laying sliced fruit on a sheet (maybe on a layer of waxed paper) and putting it in the freezer. Pull out a slice every day or two to check its crispness. The time necessary will depend on the type of fruit, its moisture content, the slice thickness, and the room's humidity.
