Thanks for the calculation - excellent finding!
I'm a bit curious about your butter need.. Can you talk more about it?
I'm in Sydney and don't regularly use air con or heating so I get seasonal swings in temperatures. It also means that my "window of spreadable butter" (WSB) is reduced to a couple of weeks every spring and fall. Other times it is either too hard to spread or starts to melt and begins to split from the milk solids.
This has led me to think that a room temperature fridge would be worthwhile to extend my WSB to the whole year.
This will do what you want but will likely need the heat/cool function to be manually switched
Edit: not seeing a thermostat or temp controls…. So would need an external one like inkbird :(
Or something like this
ADVWIN Mini Fridge 10 Liter Portable Personal Small Fridge, 220V AC/12V DC Electric Cooler and Warmer for Home and Car, White https://amzn.asia/d/0uCOYd5
Thanks, good to know! Also thanks @ metalslaw
Maybe try searching something like ‘incubator’ or ‘fermentation machine’.
My wife has a fermentation machine with temp and humidity control for fermentation, pretty like the room temperature fridge you described!WSB is now a thing :D
Butter is too hard to spread on bread, if kept exclusively in a fridge.
But, if it's kept on the bench, in a non air conditioned kitchen (almost everyone) in summer, it will melt a lot, above around 25c.
There is(was) a need for an invention that keeps butter at preferred temperature, to ensure easy spread on bread.
It has now been made, (2017 was when this page turned up on wayback machine)
https://alfille.co.uk/butter-dish/The alternative to EBC's proposal, is a ceramic bladed knife that can be heated. Either by preheating within a clamp, like a 'knife block' type device (which wouldn't be ideal, as ppl would insert a slightly buttered knife to reheat the knife… lol), or via a heating mechanism, within the ceramic blade/handle, connected to a rechargeable battery (which would obviously need a dock/way to recharge it, with something like a quick touch heating button).
I just found a product now,
https://www.temu.com/ul/kuiper/un9.htmlYay for inventions sitting in my heads for over a decade, then I finally find someone else that finally makes it…. lol. :)
Can I throw a steak in a vacuum sealed bag, then throw that in a bigger zip lock bag full of water, and then put that in this fridge/warmer, so I can sous vide my steaks?
Can I set it to 57 degrees instead of 65 degrees?
I don’t think it even has a thermostat – the specs say “20°C below ambient” for cooling and don’t mention heating at all. I suspect it will run the heating pad or cooling pad continuously without monitoring the internal temp
I reckon it’ll have two settings: warm-up and cool-down. The touch controls it talks about are probably just for turning the mirror lights on and off.
you could use this for butter if you were willing to check the expected temperature occasionally and switch it between cooling, heating, and off accordingly
What if I combined it with one of those inkbird temperature controllers? I use one for my aquarium and it works a treat to heat and cool it. Just not sure whether something like this would like having a hard power cut regularly. Would obviously need to still switch from cool to heat depending on the season but I think that would be doable.
The idea is out if it's a soft hot cold switch though because those usually reset to a default in the case of a power cut.
Would work, although could also be tricky physically having to from heating to cooling so it's more than just turning the thing on/off. Fully support the quest for perfect butter, though. Me, I'd look at finding a decent insulated container (possibly free) plus a thermoelectric peltier cooler ($10), a usb powered heating pad ($5) or light, a ds18b20 temp sensor ($3), and an arduino or ESP32 (eg Wemos D1 mini - $10) plus a small amount of pain coding. Prices are rough, but even if you add in a fan & heat sink you should easily be able to cobble something together for $30.
With the container, an option would be to find an old (dead) wine cellar/cooler off facebook marketplace and repurpose that. The motors on them frequently fail, and you can find them for $40 or less. Actually had a quick look and found one for $10. Some of them even use peltier cooling so may even be able to repurpose that as well.
Hmmm….. tempted to make one myself now. ;-)
@PlasticSpaceman: "plus a small amount of pain coding" - This is usually where my dreams of soft butter die.
Honestly, it could probably be done with an old mini fridge, an Inkbird temperature controller, and some very low powered heater (possibly just an old incandescent light bulb would do the trick). I wouldn't go for a heating pad as I would be worried it would melt the butter at the bottom before it is softened.
Benefit of the mini fridge approach is I could put my other items that struggle in the heat (like bread going mouldy) in there as well.
@EBC: Agree about the heating pad, but I'd likely put it (or the bulb) on the bottom possibly with a cover over it and just let thermal currents warm up the ambient air with the butter sitting on rack(s) higher up. If the temp sensor is placed next to the butter then there is minimal chance it would get too hot. I'm really liking the idea of the old wine cooler - they are usually designed to look quite nice so would not be too out of place in a kitchen. With coding, check out https://www.esphome.io/ - lots of examples on how to do things, and the coding itself is actually not too bad. Honest. :-)
@PlasticSpaceman: I really appreciate the actual advice for what I admit is a silly dream. I have been telling my wife I am going to make a room temperature fridge for years. It is now once step closer to becoming a reality.
Unfortunately the last time I tried that in the summer all the butter melted and it became a weird congealed water butter mess.
A fridge for makeup, what? This should not exist.
I’m curious why not?
With Aussie summer indoor temp without Aircon going over 30c easily, why not?
Lots of skin care products like lotion will go bad if left on higher temp.
FWIW $49 for something similar at kmart - https://www.kmart.com.au/product/cosmetics-cooler-with-led-m…
Good find - based on the manual for the kmart one it is very likely that the switch on the back of the BDI fridge is also a three position COOL - OFF - WARM modal.
I want a fridge that can keep my butter at a spreadable temperature (20-22 degrees) all year despite the actual temperature of the room it is in. It says hot and cold use, and it suggests it should be able to heat as well as cool. So could I have this in my kitchen keeping my butter spreadable regardless of whether it is too cold in my apartment (ex. 15 degrees) or too hot (ex. 30 degrees)?
Edit: also the internal dimensions suggest a volume of 3.78L, not 6L. How is the 6L capacity calculated?
