Food Dehydrator

Picture of Food Dehydrator

Well this project came into life not because I planned it, but because of circumstances. Our neighbours, two doors from us, placed a fridge/freezer combination on the curb for rubbish collection a few months ago, and yes, the stingy bastard I am, thought I could fix this and resell it or use it myself. I had a fifty fifty chance of fixing the fridge, either the thermostat was busted (easy and cheap to fix), or the compressor was busted (too expensive to fix). Well as it turned out, it was the compressor.

So now I was stuck with a piece of rubbish a few weeks before we move. My wife was fuming because we had no means of disposing of it and I was too proud to put it back on the curb for rubbish collection. (I wanted my neighbours to think I fixed it! LOL) After a few days of deeeeeep thought, I came up with the idea of a food dehydrator. Yes, I saw a few of these conversions on the internet before and thought, well, I do have a food dehydrator, but it was small, now I have the chance of building a nice big one with loads of space for a lot of food to process!!!

Now, as a South African, we love Biltong (almost like Jerky but differently prepared) and Droëwors (dried sausage). This dehydrator is perfect for me to make my own Biltong and Droëwors on a bit of a larger scale. Also, living in Australia, it is difficult to get hold of Biltong and Droëwors and, IT IS BLOODY EXPENSIVE going at $60 a kilo!!!! So naturally, remember what I said about being a stingy bastard, I am making my own at a fraction of the cost.

Dont you need a small heater to push in hot air and an exhaust to remove air and mositure instead of pressurizing that chamber

Sit fotos op as jy klaar is Flenters. Altyd lekker om Afrikaans te hoor.

Ek sal definitief so maak ja. Daar is net te veel goed wat eers moet gebeur.

Costarus. That looks great! Here is an image of my dehydrator in full action with some sauges (Droëwors) in the making. Luckily mine is under roof so I do not need to worry about the rain. I might consider a few fans to the side as the bottom of the dehydrator does not seem to be that effective as the top part.

Wow! Cool! I, unfortunately, cannot beer in large numbers. But it looks really great! Hats off!

Please consider leaving the refrigerant and items containing refrigerant intact.

Many
of these, especially older, devices contain refrigerant which should be
appropriately disposed of. Just as an example, "CFC-12 has a life of
102 years" with a global warming potential 2400 times larger than CO2 and when it decomposes, the chlorine takes ozone with it.

Chaseadam, thanks for the suggestion. I limited the amount of escaping refrigerant by closing of the tubes close to the compressor before cutting the lines. This limited the amount of refrigerant to that in the copper tubes and the rest stayed in tack inside the compressor.

What a great use for an old fridge!
