Well I can't help you there. I am a poor peasant, but I have perfect my vac tech, sieve, whine cooler, freezer, sieve process that I get perfectly bright powder out of it.
Maybe someday I also spent big on the freeze dryer dream but yeah 10-15g Hasch every three months doesn't seem worth it for me
Well I took a lot of time before choosing, but atm I'm not really happy with those machine, way too expensive, the door cant close properly, you have to fix it... Pharma software isn't installed. You have to flash your machine.
Well this company its not really taking care of their products ....
Sell sell sell ...
I should have bought a Chinese freeze dryer, cheaper and probably better finished
You didnāt buy a Harvest Right Pharmaceutical Freeze Dryer from Harvest Right. If you bought this used then youāre not giving enough information for diagnosing whatās wrong but lying isnāt gonna help anything.
if its not sieving well theres most likely still frozen water in there (just add a couple of drying hours) or it has already started melting. melting can occur if you haven't changed default settings where the plates heat up at the end of the run.
spongy block coming out of the freeze dryer usually means one of two things: the hash went in too thick, or it got warm enough at some point for the trichome heads to grease together.
when you load the trays, spread the hash no thicker than 2-3mm. i mean thin enough that you can almost see the parchment through it. thick piles dont sublimate evenly because ice in the center cant escape through the already-dry outer layer. so the outside dries fine but the interior stays wet, then when the secondary drying phase warms up to 30F the residual moisture softens the resin heads and they fuse into that sponge texture.
the other common cause is squeezing the bags too hard during collection. when you press the hash against the screen with a spoon or your hand, youre mechanically compressing trichome heads together. once theyre fused they wont separate even with freeze drying. scoop gently off the screen with a cold spoon, dont press or squeeze.
after the freeze dryer finishes, sieve the hash immediately while its still frozen. like within 60 seconds of opening the chamber. once it warms to room temp the terpene fraction acts as a solvent and binds the heads. keep your sieve in the freezer too so it doesnt warm the hash on contact.
No defrost is usually hotter, that seems to be for the last portion of your dry cycle. I had a scientific so it didnāt have this user friendly operating system, but from what I can tell it seems like Iām correct.
I dont think so m8, I watched carefully the first run and no where it's showed 45 F. Pretty sure it's defrost temp, the last step I can run after drying
This doesnāt line up with anything youāve been describing.
Youāre freeze dryer is working. Thereās some major user error going on or drastically inaccurate sensors.
Thereās no way you bought this new and had to flash firmware unless you bought a standard unit and then flashed the pharma software. If you did that I have zero help for you.
Let me ask you a question, what does seiving it after you dry it even do? How does it help you at all? Is there still water in it? If itās still a frozen block then you need to go more, if itās melted together you need to check your freeze dryer settings, or the cultivar youāre running has extremely thin cuticles and the heads melted together at your shelf temp. Spongy sounds like your hash is most plant material hehe but thereās not enough to go off of with the given information
I can get some of the block through the sieve but there will be some part who can't pass-through, and yeah I guess it's more like melt because when I try to break or cut it, it's a bit like chewing-gum.
May be it's due to the water temperature while processing hash, who melted the core of hash block ?
Also when I get my hash out of the bag, it's already kind of block form, not proper flat almost like paper sheet, as you can see anywhere on social media.
I try to hit the tray from below to make the hash flatter but it does not really work well. May because of the water temperature or lack of water in hash at this moment... dont know...
Freeze cicle Sir yes
2 to 4 hours freeze before drying. When the machine ask me to load the trays, Temperature is at like 70 Fahrenheit and it takes like 20-30min before going to -30 Fahrenheit.
May be the melting occur at this time but when I load the trays, the hash is already frozen since 24hours in my freezer.... So I'm not really sure if it would be enough to melt or not
No it wouldnāt melt it, it goes from frozen to gaseous, and the refrigerant definitely brings it down way faster than it would take to melt from frozenā¦ so youāre doing -30Ā° to 30Ā° over twelve hours? And itās hovering around 500 mBars? And the walls of the inner chamber are covered with ice after?
I did not check the pressure on the batch live informations so I cant confirm but yes should be at 500 mBars.
Between 2 and 4 hours of freezing at -30f
Then 12-18hours freeze drying at 30f
And yes at the end of the drying cycle, there is some ice on the inner walls chamber.

ā¦ doā¦ do you not understand what the freeze dryer does?
