On that point, I was first introduced to home freeze dryers while overseeing the guard force at the Embassy in Baghdad.
The characteristic timeless design is as popular today as in the 50's. It was first developed by civil engineer Alvar Lennin.
I found out the hard way about the anti-drainback seal when I first tried the filter and got... nothing. I did do some research afterward and learned, as you point out, that there are some filters than don't use the seal but by then I was committed. Fortunately, it wasn't all that hard to remove it, but definitely better not to have to.
the "real" vacuum pumps on those machines, with ultimate vacuum levels a few more demial places over. I've chased many a leak in my time,but it was: A.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
If you or a family member has Celiac Disease, you know it’s not easy to come up with a last-minute meal. My freeze dryer has made this so much easier!
1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.
3) Inside the front panel I installed a plastic shield over the display card and a water deflector just below the hole to route the exterior condensation to an 11x17 pan beneath the FDer.
Use a professional shipping service that specializes in handling industrial machinery. Ensure the dryer is properly secured and protected to prevent any damage during transit.
The best way to keep tabs on used options that may be available is by joining freeze-drying Facebook Groups, following them on Instagram and TikTok, or checking online self-reliance and preparedness forums.
The only downside is that the interior is now so cold that defrost time has doubled! Shop Now I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Harvest Right’s lyophilizer/freeze dryer is the perfect addition to any laboratory. The scientific freeze dryer can be completely customized with your preferred processes.
Of course, if someone used a larger can, say a #10, that is bigger than the top of website the container that surrounds the filter and captures the oil, then the "disk" wouldn't be needed at all. In that case, an AN8 fitting might work -- or maybe there are longer ones out there somewhere.
