This is super inspiring to me. Thanks for sharing your creativity and processes. Do you have to rotate the trays occasionally to distribute the heat evenly over the fruit?
It depends on what I'm dehydrating. If I'm making candied fruit with maple syrup then rotating helps a lot but for most things the speed of the airflow and the solid front door with the slots on the sides for the exit keeps the air/heat pretty evenly bouncing around. It's definitely not as precise as an Excalibur or something but I'm sure it's possible if desired. For now, this is a proof of concept that has been working well for many months with all sorts of different products.
