you can try without a dehydrator

[bluebell]

I don’t know if you have tried it but since I only rarely use dehydration I use a fan oven on without heat or with the lowest possible heat setting and the door slightly ajar. I have had good results with apples, carrots, fruit leathers etc. Probably more expensive to run but if you are not going to use it a lot or just wanted to try it would save a significant investment.
