Introduction: High Volume Food Dehydrator Racks
If you have a lot of herbs, fruits and vegetables, you've probably thought of drying or dehydrating them. You could go out and buy a purpose built dehydrator, but the problem is that it does only one thing, and it does that one thing poorly. Why? dehydrators use a heating element to speed along the process because they don't contain a fan that sufficient for drying foods.
Some people recommend just using an oven. However, that bakes the food, not dehydrating it gently.
No, what we need is airflow - and a lot of it. You've probably already got something up for the task and that's a box fan. Now this Instructable will show you how you can neatly and efficiently turn that in a massive food dehydrator!
Step 1: Materials and Tools
For this you'll need:
Non-metallic door screen
1" x 2" wood boards
The tools and supplies I used was:
Hand stapler and 10 mm staples
Air powered stapler (could use nails or screws)
Step 2: Cutting the Frame
Measure the length of your fan and cut the wood boards appropriately. Since the fan is square, you'll need four pieces with a 45 degree cut on each end for each frame you want to build.
Step 3: Glueing and Assembling
Apply a small amount of wood glue to each corner and clamp the corner together. Use your air stapler or other fasteners to securely fasten the corners together.
Repeat for all four corners remember to ensure your frame is flat and not skewed.
Step 4: Applying the Screen
Lay the screen across the frame and staple ever two inches along the frame. Cut off any excess.
You're done! Stack the frames and start drying!
