I filled all 7 trays of my dehydrator with squash and ended up with less than a quart of dried squash. Cut the squash 3/8 thick steam blanch for 2 minutes, cool in ice water, place on the trays, set the heat to 135, ran for 9 hours, turned down to the coolest setting, went to bed, and they were all dry when I got up. Put the dried squash in a quart sized freezer bag. Labeled with the date and popped into the freezer. I plan to use in soup or something this winter. I have to add that while the squash were drying I tasted a few and they were pretty sweet and tasty.
Next time I plan to cut the squash thinner and sprinkle with cayenne and salt, maybe some ground dill too before drying. I am not going to blanch. I am hoping to make chips.
