i am trying to freeze dry some distillate infused edibles, however they are not freeze drying properly
What hardware and parameters are you using?
Harvest right consumer has a candy mode of you download firmware update.
What information can you share about the candy and distillate itself?
i think regualr candy does it well because of lack of oil content
if you cant freeze dry distillate you probably cant get the look you are going after with stuff that has distillate in it
freeze drying is sublimating water and when all the water content os gone from candy oil remains and hinders that cool freexe dried candy process
just soak them in chamoy and sprinkle with tajin

Just tried this experiment as well with distillate infused gummies and unfortunately did not go as awesome expected.
I let run in candy mode for 24 hours (145°F I believe) and did not get much of a change. They puffed up a bit and hardened up some, like a stale gummy.
From my understanding and countless hours on old people freeze drying Facebook groups, I have found that only a certain brand of gummies seems to do that puff thingy that you see all over. I believe it was black forest and had something to do with them using juice.
I believe the idea is for the candy to melt down, thinning it out and allowing vacuum to remove undesirables (water?) Hmm maybe instead of pouring into molds, pour into freeze dryer tray and try like that.
The freezing part doesnt seem to mater at all with candy but I could be wrong.

At that point can you just use a vac oven? Is it really freeze drying at 145f? I’m very interested
The harvest rights run a heat/cool cycle with the vac. It’s actually not that much technology wise… just need a good curve to program a controller/raspberry pie and you could build one out of metal shelves and heat tape/mats and a chest freezer(they vac awesome)

@cae44165 what are you trying to achieve freeze drying them?

Can you link me to some products?
A bit more information is required. What kind of edible? I assume gummy but if you’re trying to do things with a high fat content, you’ll have trouble. Even 10% fat is hard to freeze dry for food products. High sugar content samples freeze dry weird but there’s a method to the madness.
When you freeze dry, you have two major considerations. The first is the glass transition temperature which is the temperature at which the crystal structure of the formulation will anneal from amorphous to crystalline. You usually want a crystalline mode because the ordered structure allows water to be sublimated in an orderly and rapid manor whereas an unordered amorphous phase can trap pockets of water.
The other is the eutectic which is the lowest possible freezing point of your mixture. As you remove water, you will concentrate products that can lower the freezing point of your formulation, ruining if the 3D structure of your formulation. Ex. If you have 1L of 5% CaCl2 solution you are freeze drying, it’s freezing point is 5C, but as water sublimates away, the freezing point drops as the CaCl2 concentrates until ~30% (150mL) CaCl2 where the freezing point is -50C, and if your freeze dryer isn’t that cold, the formulation will melt and ruin your run. Basically the eutectic is the maximum temp you can freeze dry at; the eutectic for most sucrose solutions is -26C.
This knowledge is used for freeze drying sensitive chemicals and delicate proteins in aqueous solutions where the dissolved solid content is below 10%. Gummies range from 50-80% dissolved solids, so you’re probably seeing a trapping effect from the gelatin/sugar giving that puffing effect above the eutectic temperature.
Freeze drying warmer may help but lowering the dissolved solid content should help as well.

Sugar is addictive. As soon as it touches your mouth, your brain releases dopamine. Immediately stopping consuming large doses of sugar does cause withdrawals: anger, depression, lethargy, the shits.
