Thank you, I saw a Kickstarter for a portable dryer that used vacuum technology to dry clothes an I wondered if it actually would work. Thank you for showing me that it wouldn't.
It probably still needs some heat source like an IR lamp to be faster, as only the warmest molecules evaporate and the water will progressively get colder otherwise...
Oddly I was watching star trek and I happen to be drying clothes on radiator and I thought I wonder if u could dry clothes via a vacuum chamber like in space when water bubbles out of stuff... Now I know it's all about heat exchange too... Makes sense.. Thankyou for answering my strange question....
You have the basic principle to make it work to its full potential you would have to apply heat and thus pull more vacuum as the water vapor expands. In addition you would want an inline water condensed/collector so you don't ruin your pump. And if you want to shout the moon a way to agitate. But after all that a clothesline is your best bet. The channel FirstBuild is working on a similar project.
I already have thought about adding 117 volt heavy duty heater, that will keep it above freezing as during tumbling instead of just sitting and doing nothing. I figure, if the temperature would be around 70 degrees inside the vacuum dryer. Because of heater, you can dial in 1psi. that will bring it to boil point at below 70 degrees. How ever; you may have to slowly let the air in to prevent from it's getting too hot as the air will compressed. Some other guys say; you pull more vacuum out. Frozen is frozen that even is founded on moon where sun never had shine. I think heater is better solution.
You shout add a hit lamp on top of it. If you get to 50c with the vacuum, that will dry it in 10 min. Lamp delivers the hit by radiation so the lack of air is not a problem.
Would you try adding a little bit of warm air at the same time as you're pulling air out and see if that does anything different. You could try cycling between pulling a vacuum and adding heated are as well. Also please include how much energy is used for this process
I was thinking to make the same project but instead of warm air, I'd heat the entire cylinder. Perhaps putting the vacuum chamber inside a bigger insulated bucket filled with hot water while vacuuming intermittently using timer (to prevent damaging the pump). But the problem is, since there is very little air remains, convection heating will be far less effective. Radiative heating can be achieved by painting the chamber's internal matte black. Just an idea...
Put some LiBr solution in a container with a lid having enough pores to absorb the moisture. It might actually work to absorb the moisture, hard part is to regenerate the same for next cycle. You might have to connect a solar water heater to increase LIBR concentration.
I pull a vacuum on AC systems almost daily. It's not freezing, if it was, then we could never pull a vacuum on anything hvac/r related. It's just a huge amount of moisture to be removed that way.
Thanks for sharing your perspective! Absolutely, pulling a vacuum in HVAC systems is primarily about removing moisture rather than dealing with freezing temperatures. Moisture can cause issues, so the vacuum process is crucial. As the owner of an HVAC contracting business, I encounter this process almost daily. If you have any specific tips or experiences you'd like to share, or if there's anything else related to HVAC/R that you find interesting, feel free to let me know!
@solarpowerelectricityandel2915 it gets cold due to the transfer of the 410a refrigerant, not due to the process of vacuuming. If a vacuum caused water to freeze, we couldn't do it. Now, we are talking about, usually, very small amounts of moisture, but water boils at lower vacuum pressure, not freezes.
I think. Decreasing the area Heating the plates smashing clothing heating directly on. On the material and vacuum. Can dry your draws in one min. At 500 quarters a drawer. Not a load. But your drawers
I put in a vacuum chamber closed the end the vacuum is connected so no moisture can travel back to vacuum i then added a small heater to the side and rotate every 30 min or so clothes dry in a hr all i did before was rotate in washer extra spin after wash
@@solarpowerelectricityandel2915 Last Saturday I was drying a pair of jeans, and there were no sparks. I believe it's because all metal parts in them are brass, not steel. Steel would rust. I think that sparks are generated only with metals that react with magnets and stainless steel, brass, aluminium doesn't, therefore there are no sparks :-)
@@solarpowerelectricityandel2915 I don't like to but sometimes I have to ;) It would be great to put a microwave oven in a vacuum chamber and then try drying clothes ;-)
I meant perhaps to incorporate some method of warming or heating the vaccum chamber using a heating element or radiator, think like a fridge in reverse
the chamber is good for impregnating varnish on an electric motor. works great for that
Thank you, I saw a Kickstarter for a portable dryer that used vacuum technology to dry clothes an I wondered if it actually would work. Thank you for showing me that it wouldn't.
Where does the air go when it is totally saturated? Would less clothes and more space for water vapor work better? Do you vent the moisture?

Use it for canning dry ingredients like beans and rice, flour ect!

There are at least two parcial vacuum tumble dryeras available now. One uses infrared light the other I think heats the whole thing.

Riley Evan Lloyd clothesline is definitely the most effective for saving electricity thanks man I appreciate it I'll check him out

I think the addition of a microwave oven would complete this device. The microwave heats the water directly and the vacuum would remove the vapor.
dude wanna help bilt a prorotype
.
what if u introduce heat into the chamber by tungsten light bulb.

what happens to a R-410a tank when you charge a unit?

What did you expect? Sunlight is free energy. Lol
If you put the clothes on a rack, would it pull the water out of the clothes so I don’t have to wring the water out.
can you make beef jerky in the vacuum chamber not sure if that has been done
Damien Baynham most likely but I'm not sure where to start

Thanks for posting the results.
Likely not freezing to the clothes, likely boiling off. That's why it's not pulling out a whole lot in liquid form because it's boiled off
Fruit & Vegi dryer? The sun does this pretty good though
I wonder how effective it would be if you added a heat source to the camber.
no air to heat means radiant heat only
@@solarpowerelectricityandel2915 use IR maybe?
@@prajwalbharambe343 air moving and recirculating and flipping the close
Conduction heating will work.

Excellent what do you do with the metal zipper and the Sparks and metal that flies off of it that burns the pants

@@Radoslaw1986xx Good to know that you like to cook your clothes.

@@Radoslaw1986xx like a microwave vacuum dryer? Not like they have those already or anything.
Did you put a camera and a speaker in there?
Need to heat up the container?
Wanna be a hero...dry out some hygroscopic 3D printer filament...seriously :P
I don't know if i need to buy a printer now
Looks more energy intensive than a regular dryer
The electric motor from the pump is about 500 Watts a normal electric dryer is 5000 Watts
You could warm the chamber using a heat pump to keep the temparature stable.
a Heat pump needs air in a vac no air
I meant perhaps to incorporate some method of warming or heating the vaccum chamber using a heating element or radiator, think like a fridge in reverse
infrared heat or contact heat will heat it up and both will not get but one side of one peace dry
Add a small heating elememt, then you got a freeze dryer.
Sia Mean that sounds really good
@@solarpowerelectricityandel2915 you said it Right !!! ........Sounds really Good......but Sound cannot travel in a Vacuum !
Put it on the stove! 😀
use it to make ice
My dear they will do this normaly to dry wood with toomuch problem freezing and heat up so such
Good luck
Tumble it
AND???? So????
