Try this, we have one and it gets used for: drying fruit, apart from the apples, pears and strawberries from the allotment, when bananas are going cheap, kiwi fruit is absolutely delicious. Lemons, oranges and satsumas for coooking out of season. Breadcrumbs, chillies and all manner of things OH passes through this. One of the better gadgets we have bought.
If you've got space and are good at DIY try making a solar dehydrator. Requires no electricity, it just concentrates the heat of the sun to dry your produce. See the following link for a simple design:

The basic idea is wonderful. Being somewhat pedantic about things, I would make a few adjustments to it for greater efficiency
1) 'double glaze' the solar heating section (2 sheets of plastic with a small gap, or the off-cuts from someone getting a conservatory with a multi-wall pollycarb roof)
2) use something a bit more durable than cardboard (it may be worth a couple of pounds not to have to start again if there is a shower while it is outside)
3) put an 'umbrella' lid over the drying chamber (again, a precaution against showers, but make sure it doesn't interfere with ventilation)
If you really want to get drastic, you can make the black 'base' of the heating section out of something like bricks (a nice slab of slate would be ideal, if you happen to have one handy<g>), which will absorb and store some of the sun heat all day, and then give off the stored overnight, so that anything which needs longer drying can be left there (weather forecast permitting)
Flowers come in too many colours to see the world in black-and-white.
Hilary, I agree with your improvement ideas and there are plenty of sophisticated designs that offer more efficiency. I've even seen some designs which include solar powered fans. It all depends on how much effort (and expense) one is prepared to invest. However for the cost of a commercial electric drier it would be possible to design and assemble a very effective, efficient and robust solar drier.

Nice little project.................
Yep. I had a few bright ideas already, but hadn't thought of making the heat chamber separate from the actual drying chamber (and it is so obvious once you've seen the diagram!)
Our Spanish property has a solar water heater based on a couple of secondhand radiators, and some roof insulation!

I Have done the same here. My first solar collector is a black painted radiator, boxed and mounted on the roof. It worked a treat so I added another. Even at this time of year with a bright day there is free hot water.
yes i have got it and will be trying it this weekend, i got the catalogue aswell and they are down to 26 quid and you get 2 free knives with them!!!!!!!
i will post an update on how i got on with it soon.
