That's normal. I've heard some people who really know what they're doing (and use a lot of worms) can start with kitchen scraps and turn out fertilizer for plants within a few months. My experience has been it takes about a year (sometimes a little longer) to get started. And usually the results are best for outdoor because they're so full of life haha. Super valuable stuff though, I can see why farmers value sources of plant nutrients. Nothing goes to waste!

Hmmm okay so it's your fan that dries things out so much, gotcha. If it's not one thing it's another!
