Vaccume drying

Being new here i don't know if any one has mentioned this before. A few weeks ago someone came to town with a bunch of wet Cubes. Well i took some of these to work and threw them in a vaccume dessicator and applied 29" of vac. This was allowed to sit overnight. When I returned in the morning the shrooms were completely dry And had not lost their shape the lesat bit. For those of you without a professional lab to work in here's what you can do.
Ritchie Sells a vaccume pump for evacuating refrigerant lines. It pulls 15 cfm and pulls ultimate vaccume when new. The beauty of this perticular pump is that it boils water at below room temp. You then need to find an enclosure that will hold up to 29" of vac. Square enclosures do not work. When you have both attach a braided hose from the pump to the enclosure insert shrooms and bammmm their dry.

You seem to know your stuff about vacum's. Will a vacum pump that will pull a constant one atmosphere (whatever that means) work, even if more time is required? Thanx for any input. SixTango

What is the price on the vacuum pump you speak of/ where can it be found? Do you have any ideas on suitable enclosures?

29"? so you had 0 pressure (internal)?? I am not used to inches, I am far more comfortable in torr.. I assume this is a roughing pump, so it could get down to 5-6 torr.. turbomolecular pumps are far too expensive to use in such an application, and I believe that they would be damaged by such a large amount of water passing through them.. An ion pump would be just crazy.. talk about short lifespan.. Does this vacuum dissicator use anything besides evacuation to dry? Any sort of condensor? btw, square enclosures do work, it just requires a more robust design If anyone knows of a cheap (edit: cheap really is an issue, the ones I have seen were very expensive, but their application was different..) pump which can get down to the 10e0 torr range, this could be something which may become quite useful to those who grow large quantities... the only downside I can think of is the $$$.. Cool idea, thanks for bringing it up.

I am quite interested in this also. Has anyone had any additional information since the last post on this? Do You have a reason for why the pump You specs You wanted are at such a low vacuum? Is 10e0 torr really necessary? I would like to keep this discussion alive. come on step lively people.

The problem is getting a suitable containment system, one that opens up so that the cubes can be put inside but then closed again with a suitable mechanical seal that can provide for such a vacuum. BTW I can get the pumps if anyone is interested. I'll pm pricing for the various brands I carry for anyone interested.

For a containment chamber -- use an AA type PC. Butt wipe simple to hook up & use. Place a valve between the 2. Run pump to 29 pounds & close the valve. To save the pump from running -- against itself & turning to toast. SixTango

Would a All American produce a perfect seal? It dosn't have a rubber gasket. i would think a standard presto would work better and be smaller anyway. My AA used to hiss out the sides every now and then. dunno if it still does, i havn't been watching for it.

If your AA PC hissed out the sides, something about it's metal to metal seal is not kosher. Clean the contact area - carefully .
The Raccoon has 941 type (almost 60 years old) & it seals perfectly - time & time again .
I suppose any with a GOOD tight flexable seal would also work, so long as it had a threaded pressure gauge, you can remove & replace with heavy gauge copper tubing connected to a vaccum pump.

this would be a cool experiment, but wouldn't be useful because in it's fresh expanded state, it would be extreamly brittle. you likely couldn't put them in your pocket without crushing them. For small applications, what's to say a qt. jar wouldn't work. they are vaccume sealed during canning. i wonder what the rating on them is.

although I have never used a hand pump, I think that there is no way in hell that I would attempt it for this purpose..

A friend's lab has something like one of these: http://www.tescal.com/turbomolpump.htm I think they run it for a few days before they reach their desired pressure..
