Do all dehydrators use heat?

I was just wondering if all food dehydrators use heat as the dehidrating agent.
Are there any vacuum dehydrators?

I think they all use heat to a certain extent. All of the basic like kitchen dehydrators with trays n shit will use heat IMO.
Why worry about other dehdrators when the ones you can get will work the best? Go for the Nesco American Harvest and whatever you do, keep the heat on the lowest setting.

And by vacuum do you mean as if it was sealing something or sucking something out?
On my dehydrator its just air getting sucked into the bottom through all of the trays of shrooms. But the higher heats are for like meats n shit. GL man

In theory if you could put mushrooms in a container and then create a powerful enough vacuum, you would cause the water to boil and evaporate at room temperatures (and then the vacuum pump would suck it out). This setup would avoid the heat problems.

Boiling water......might affect potency.
I know that when I turn my dehydrator on above 110F, I can definately tell that there was some loss in potency. Dried a batch on 135F and they were the weakest fucking things.
Fan drying is effective but takes several days. Its cheap and works well but the dehydrator is the best IMO.

Pscyho somatic, psilocybin has a melting point of 400 F. Read this thread, temp. will not affect your potency.

As you lower atmosferic pressure you lower boiling temperatures. At a strong enough vacuum you can boil water at 70?F or lower and even if you couldn't lower the vacuum to instantly boil off the water, the lower pressure would make the mushrooms dry really fast at low temperatures .

Just imagine the combined drying power of those babies using a dissecant also...
I really must try to get my hands on one. Its a pity they don't ship outside the U.S.

i've been saying for a while that heat will not effect your psilocybin, at least at any temp we use to dry shit.
coda, i was about to ask you if this means you go back on saying that you noticed a loss of potency and now think that it was psychosomatic. but then i realized it was hyphae that said it.

if the water inside mushies boils in a vaccum jar, where will the water go? you'd have to let the water out somehow or else idk if it will leave the shrooms.

it goes into the air as low temp steam. from there it either goes out or into desiccant.

Quick bit of physics:
If you take all the air(gas) out of a container you create a vacuum. One of the things that regulates evaporation is the ratio of the substance in gaseous form compared to the liquid. That is why it is so hard to get humidity in a fruiting tank up to nearly 100% and we have to use different methods to do so (perlite, bubbler, misting) because just putting a glass of water inside the chamber would not work.
The vacuum dehydrator would work following this same principle but in the opposite way. Because we have taken a lot of the air out, the "relative humidity" is really low. Because of this, any water inside the dehydrator will tend to evaporate creating more gas and decreasing the vacuum. All you would have to do is spin the handle a few times, take out the newly formed air, which will essentially be moisture, and you will have effectively taken the water out of your shrooms without the help of heat.
