I have two dehydrators. One similar to the above but no fan and one temp setting. Well actually two if I count the off. It was garage sale cheap.
I decided I needed a bigger one with removable trays, fan, temperature settings so I bought an Excalibur. I like it but don't use it much. Too big to run for small batches.
And I bought a mandolin. Don't use it much. The knife is handier and easier to clean.
Hmmm. Would this be one of those $100 hamburgers?
May I ask how you will use your dehydrated squash? Did you season them first?
