I have always wanted to make a REAL food dehydrator, but all the plans I have found always start out "make a box..." That lets me out! I don't have the patience to make a box, let alone the skills to make it square, then add racks (also square!!) so I came up with a super easy way to make a container that looks like the commercial dehydrators using stacking trays in a cylindrical shape. It took me less than an hour and cost about 20 dollars. I could have scavenged and cut that in half, as I am sure many of you readers can. Read on!
Step 1: Things You Will Need
This design is so easy to make, all you need is a cylindrical tube, sold as a concrete form at the hardware store for around 5 dollars. They come in different diameters, I chose 30 cm. You will need some mosquito net, a zip knife to make the racks, and a staple gun to fix the net to the tube sections. For the drying unit I used an old heater made for warming up the car interior. Don't really know what you would call that in the US, since I grew up in Texas, and the last thing we would ever invent is a way to warm up the car interior! But here in Sweden it is common to own 2 of the things... Mine has variable heat settings, from 500 W to 2000 W and is built for 100% duty cycle, or constant running without overheating. (I paid 5 dollars at a local auction) I fould a small electric space heater online for about 15 dollars that would work. Add an oven thermometer and we're in business.
