The first set of plans are from the third solar food dehydrator in this video



And here is a sort of fly-by of the plans:




The second set of plans are from a build we did at my place a few months ago:



and here is the fly-by for these plans:

I am looking for threads discussing the new model of solar heater and input on any particular information regarding the shower glass such as whether it was the best of many options, any tips for gathering it, and if there are kinds to avoid.

EDIT: Found two.

2017 Homesteaders PDC (permaculture design course) & ATC (appropriate technology course) in Montana

Page 6

Page 7


2017 ATC solar food dehydrator

Observations: It sounds like the shower glass was decided on after the structure was built. Would it be ideal to size the structure to fit the glass laying as in the design, or rotated vertical, or just find the glass first and decide based on what you have? Are there issues with toppling if the structure is too narrow, requiring a base?

The Wheaton ATC Class of 2017 designed their dehydrator in the classroom.

We believe you should avoid glass with solar treatments.

Meaning films applied to cut UV exposure and such? A search using the phrase "glass solar treatments" doesn't bring back any useful information and I would appreciate some context to make sure I understand. Also please check my edits.

Air flow is very important in solar dehydrator design. I would worry about air flow if this design were to be narrowed.

We used what glass was available (craigslist or something), and did not bother cutting the pieces. Instead, it over-hangs the exterior walls of the structure which is a roofing benefit.

So excited to see these plans. I had some years ago but could never lay my hands on them again. I am looking forward to building a dehydrator and putting it next to my solar oven next summer in my SolKitchen. Thank you!

Howdy, I'd like a personal affiliate link to the solar dehydrator plans that I can share. I don't see it in the "Explore Products" section of my control panel though.

At the bottom of most pages there is a link that says "affiliate program".  It links to this:  https://permies.com/wiki/affiliate  - which I think is a pretty good page for getting somebody started with the affiliate program.

I am now looking at my affiliate console and i see nothing under "explore products".  I reported it as a bug and hope that we can get that back quickly.

How do you keep birds, bugs, mice, rats, from eating whatever you put in these solar dehydraters?
I was all ready to build one to dry mesquite beans when I remembered how fond pack rats are of mesquite beans.

Sandwich and/or pin bug screen and/or wire metal mesh at air intake and exit points.
Door can be weather stripped and latched.
The environment inside is not a desirable living environment (during the day).

Thyri Gullinvargr posted this on another thread when someone asked about the meshes/screens:

Has the effectiveness of the two models been compared?  Anyone prefer one over the other?  These are great, and so timely as I plan to build one soon.

I don't believe there have been scientific quantities/tests yet.

Where does the water go? Is there any way to reclaim the moisture?

The moisture joins the air in the dehydration cabinet, and escapes out the back top opening.

Inside the dehydration cabinet, the moisture tries to equalize, but is never able, because the air continues to move out as new air comes in.

This unit is not concerned with capturing the moisture and containing it. Maybe install an air-well elsewhere to grab moisture from air, or add this moist air to other moist air so it will drop/sink somewhere, but not here. This is not in the scope of our project. If dehydrators can not perform there purpose fast enough, the moisture will cause the food to spoil.

Yes. My comment was a bit awkward. LOL!

You answered what I really wanted to know: Is there a defined outlet for the flow of moisture to escape?

I'm looking for ways to combine solar de-hydration with water purification using condensation of moisture from the air.

For example, for my purpose, I would use your drying chamber to evaporate brackish water, like a swamp cooler, but to produce a hot, high-moisture airstream into a condenser.

Ideally, it would be a passive system, except for wind/solar-powered fans and pumps.

A less industrial approach would use a greenhouse to store the moisture and condense it using cool night-time temperatures, or surfaces cooled by other swamp coolers. The condensation-dried 'cool' airflow could be redirected back into your solar heater.


How much moisture (by weight) does the dehydrator remove? Have you measured your required/optimum airflow?

Why? You might ask. Because want to understand how our human-controlled systems interact relating to the flow of energy and moisture.
