Raisins are just grape jerky :) Arrange pretreated fruits on drying trays in single layers, pit cavity up. Dry at 140 degrees F (60°C) in an oven or dehydrator

Raisins are just grape jerky :) Arrange pretreated fruits on drying trays in single layers, pit cavity up. Dry at 140 degrees F (60°C) in an oven or dehydrator. Does anyone have an oven that can maintain such low temps?

The Anova Precision Oven is one, it goes as low as 77F (25C).

  Much lower than that and you are getting into dual use oven/refrigerator mode!

At least in the US it seems to be the exclusive purview of high-end ovens, but there are ovens with proofing modes, which would be even lower temperature than that. Warming modes of around 150F are somewhat more common.

i've seen recommendations about setting the oven at the lowest temp possible, and then leaving the door slightly open. i've also seen electric only ovens be able to set lower temps than gas only. i've only ever dried herbs in the oven because of the temp issue. for everything else, i just bought a dehydrator that can be set to the lower temps.

I've used the incandescent light in my oven to keep sourdough starter warm before. If the wattage is too low, you could hack together a simple thermostat driven relay and a larger light bulb run into your oven.

  A big cup of hot water works pretty well too.

I bet my car hits 140 in the summer sun.

  I accidentally made raisins one summer by forgetting a cluster of grapes on my car dash for a few days. They tasted pretty good!

Toaster ovens are cheap and have good enough thermostats.

Not household ovens as far as I know, this is why I bought a commercial one (UNOX - an Italian brand) that allows me to set a low temperature. It’s basically a convection oven with PID.

I use convection mode on my oven and set it to 170F. Convection mode on my oven doesn't actually use the temperature you set it to, but some auto slightly lower temperature to accommodate for the convection. I don't think it's as low as 140F, but I get good sundried cherry tomatoes out of it.

For dehydrating food, you'd also want it to have a fan + turn over air pretty rapidly. That speeds up the process, which matters even more if it's monopolizing your oven! A "food dehydrator" mode would be much more than at least half of the dozen modes our oven does have; I wonder why they omitted it, or if one mode could be tricked into that use case. It definitely has a fan to actively vent hot air from the oven cavity (I think this is mostly to protect its computer, and not particularly useful for anything except cost reduction), and it has a proof mode, so I know the thermostat can drop down far enough. As an aside, LG ovens have the worst firmware I've ever encountered on a home appliance, and it is by a large margin.

  Just put your oven on convection roast at the lowest temp possible... boom dehydrator mode

  Firmware on an oven? My cheap dehydrator has a thermostat and a on/off switch. My cheap oven also has a timer. How is software warranted on an oven?

    Ovens are one of the few appliances where I can see some sense in smartifying them, honestly. Turn it on to preheat before getting home (or if you're just too lazy to get up), have it send alerts to your phone when the timer goes off so you don't miss it due to being on the other side of the house or having your headphones on, check how long's left on the timer before deciding whether to start watching a new episode, stuff like that. There's a combination of long cycle time + necessity to respond urgently that creates an actual use case that isn't there for eg toasters or dishwashers.

      >Turn it on to preheat before getting home I know so many people that shove used pots/pans in the oven when they just can't face doing the washing. Turning the oven on when you're not home just sounds like a recipe for disaster.

Many air fryers have a "Dehydrate" setting.

  The “multi cooker” unit I have made by Ninja has such a feature, though I’ve found various aftermarket “racks” are needed for good performance dehydrating various stuff. It’s fucking excellent for drying mushrooms, for example. Whenever I have some left over from cooking or harvest that I can’t use immediately, I just dry and powder them to use as seasoning in soups and stocks and such. Other food scraps from cooking that are not destined for compost can be treated similarly, if one wants to get into making their own spices.

My oven can be used to prove bread dough at 30°C

I own an Excalibur food dehydrator (since approx 2005), but using it requires adequate space and electricity. We have a fig tree, a pear tree, and tons of herbs. Most of that is for whatever frolics outside though. Last year I was also on vacation at a farmer who had tons of fruit and nut trees on his yard. But people didn't wanna come to pluck so it ended up rotting on the floor. That made me sad, and it makes me sad I have this amazing device unused. But at least the birds and other animals such as bees and insects get to utilize them.
nsenifty 3y ago
Bosch ones (at least the one I have) can even be set to 100F. I haven't actually tested how well it maintains such low temps, but I use it for proofing.

You can just prop the door slightly open, and use convection, if possible. It sounds energy inefficient, but when you are drying, not just heating, you also have to replace that humid air in the oven.

My grandpa used his attic to make raisins. I don't know the process he used but we kids would sneak up on a rickety wooden ladder and there they were, hanging from a strings. The raises were never like the packaged ones, they were a lot bigger and chewier and a lot tastier.
