Danger! Offensive comments ahead!
Freeze drying run complete
I ended up with just barely a small amount that didn’t get totally dried. All in all, it took 2 days.
How much I managed to do in this partial run

When ice sublimates in a vacuum (that’s the process where by ice goes directly to water vapor without first melting), it requires heat (just like when you sweat and the sweat evaporates, the process of evaporation removes heat thereby cooling your body). This causes the ice to get colder and colder until it’s so [...]
It worked

Making little ice cubes instead of big ones solved the “Honey, I destroyed another blender” problem. Another round of freeze drying under way, all four shelves in use this time. I would estimate that the machine is at roughly 50-60% capacity. I didn’t have enough to fill it up
Another new blender…

So, I replaced the blender of ryeth’s that I destroyed. The base unit was fine, the blades were fine, it was just the polycarbonate blender containers that I tore the holy living hell out of. So, I bought the same unit again, and because we have extra blades and an extra base unit, [...]

I was only running one tray this time. I specifically didn’t add any heat, although I stirred the mixture roughly every two hours. Total time to freeze dry was about 44 hours, including secondary drying. I’m hoping to get the total elapsed time down to 24 hours including secondary drying. Material [...]

I started another run last night. Only a partial run, 1 tray out of the 4 is all that’s in use (although it was pretty full). I’m controlling the method in which this tray is dried in order to provide a control for some experiments. Although it’s not done yet, I can [...]
Interesting EBay question

So, I have my little freeze dryer and one of the extra vacuum pumps up on EBay to see if I can recoup any of my expenses. I gave a very detailed explanation of the freeze dryer and my modifications in the auction description. One person, though, had to ask me a question. [...]

OK, so I thought I would run another batch of freeze drying yesterday. As some of you may remember, I currently use a blender to convert the ice cubes of pre-frozen material into a snow like powder. Well, when running the blender, less of the ice melts if you pre-chill the blender container [...]

just how much water came out of that freeze drying run, here’s the ice chunk from the condenser after several hours of melting
Yes, yes…I know I have webbed toes….shut the hell up.
No more itty bitty freeze drying runs…

Freeze drying is actually an expensive process, energy wise. It consumes large amounts of energy to generate both the cold and the vacuum needed. However, once you’ve got the vacuum and the cold, neither of these items are strongly tied to the amount of stuff you are freeze drying. And the drying [...]

Or trailer trash scientist, call me which ever (I heard that ghetto is now considered a racist term, which is such total bullshit, ghetto is a financial/social slur, not a race slur, there’s lots o’ white folk in the ghetto). I’ve been running my freeze dryer. It requires a cooling water supply to [...]
