Yes or no. It depends on what the food is. The stacking is not usually a problem, it's the total water load of the batch. We load the trays with more than one layer for many items. For some items we put a piece of parchment between the layers ( th-cam.com/video/F2351166JZM/w-d-xo.htmlsi=tgcladY46lQBlFjZ&t=512 ), most of the time we just have layers with nothing in between.

(The chamber wall) With the medium machine it's in the 10 to 12 lb range; I mostly try to load mine to the 8 to 10 lbs of ice range spread evenly :) across all the trays.
@@richardallan5460 Yes, we could _physically_ fit them in our machine (the newer 5 tray medium has less space between trays), but again, the limit is about the water weight. A double layer of full blocks of milk would be nearly 20 lbs of water. Four trays filled with blocks of milk is 10 lbs.

In my experience, lower fat milk with less sugar works best. The time I tried a brand name whole milk, it was a disaster. It looked like blown cotton candy in the freeze dryer. Because of the high humidity here in the South, the dried milk does reconstitute quickly if left out. It could be that is wasn't completely dry, although the trays felt dry. It was a huge mess😳 The second go around went perfect. Lower fat/sugar as well as pre freezing did the trick.
I have not had a problem with milk of any kind. I've done chocolate milk, 2%, whole milk, and even heavy cream. Do you have a newer machine? All of the people I've heard from that have had a problem with milk or ice cream have had a newer machine. There is a work around solution to this problem (check pinned comment from Neil Feit th-cam.com/video/gAL0BUmdtvg/w-d-xo.html) and there may be a software update to allow for extra freeze time. (check pinned comment from Baneironhand th-cam.com/video/wq7Xz8xfPsY/w-d-xo.html) With my machine I use the custom cycle to make sure the milk is VERY cold before starting the vacuum drying process, at least -40f.
I also have only ever had bubbling when the milk was not thoroughly frozen when the pump turned on. Prefreezing has solved all of those problems for me. Whole milk, cream, chocolate milk, eggnog, etc all dry well so long as they are frozen.
Is it better to pre-freeze before putting in freeze dried machine? I've seen lots of folks on TH-cam seems to do pre-freeze. So I'm kinda wondering why. Does it save time and electricity by doing that?
Pre-freezing is not required. I doubt it saves electricity; it takes a certain amount of energy to freeze something in either machine. For me it's mostly about time. I prefreeze almost everything because: 1) it saves hours of freeze dryer time for each batch, 2) I do have the older, tilted machine which means I can't pour liquids into the trays in the machine, (though I could pre-freeze directly into the freeze dryer trays in the freezer. I would need A LOT of trays) 3) I make very large batches of food when I cook, so I may have 5 freeze dryer loads from a single batch, 4) prefreezing slightly lightens the load of ice in the freeze dryer 5) by prefreezing in the small trays I have pre-measured quantities when I do the final bagging 6) we do have a lot of freezer space available. We have had up to 15+ batches of prefrozen items waiting for the freeze dryer.
@@SchoolReports talking about more trays. Did you know you can get an 8 shelf insert for about $450? Just a thought. Of course you would have to purchase more trays but its worth looking into. All shelving inserts are interchangeable between the pharmaceutical versions, (which doubles your shelves in the machine) just make sure they still use the same connector in the back as the new ones. If you do a lot of liquids it will double your capacity but just remember theres an ice limit to the drum, meaning the ice capacity of your machine will determine the amount of liquid you can actually displace I think.
@@kristoskalemanis Wow! Thanks. That might be interesting for some items, but I can't even fill the 4 trays 100% with liquid items without going over my self imposed water/ice maximum. The way I use the 7 x7 pre-freeze pans, if I were to totally fill the freeze dryer trays, I end up with 20 cups, or about 10 lbs of water/ice. I try to limit each batch to a maximum of 7 or 8 lbs of water/ice.

We have an older FD, with 5 trays. We seem to have problems when we load each tray with all raw eggs, or all bone broth. We always pre-freeze. We have had massive blow ups.

Blow ups in the freeze dryer while freeze drying milk should not be a thing. The total maximum amount of water content per batch is dependent machine size, as I'm sure you know, but that should have nothing to do with this issue and I'll get back to that later. My first question is; which firmware version is your machine running? Can you run it in custom mode?

What size oxygen absorbers do you put in the bags and how long will these store. Also, how much water do you add to each package of milk to bring it back to liquid?

Could you double the portions/batch on the trays by stacking them on top of each other?
