@Photon_noir has stated before that freezing of biomass seems to be more inportant than not
@cyclopath stated that freezing is not done by HIM so much
Can the both of you clarify ?
I freeze well -80C or i don t room temp nothing inbetween
For smokables like shatter and wax with EToH I’ve found it’s crucial to freeze your material. I’ve extracted at -65c withgood success on preserving color. How are you going to reintroduce your terps to shatter and wax?
We use a centrifuge to separate the terps from the hydrosol and misc matter. We then mix the terps with the crude after it has been almost run down fully. Then pour and do a final purge in the vac oven.
Interesting…feel it retains the profile of the plant.
Sounds like you are doing it the right way for ethanol extracts. Definitely freeze your biomass as well as the container you are doing your extraction in, as well as any extra things that could add heat (such as a panda spinner for ethanol removal, or if you are using a cup 15 or somthing, consider running a batch of frozen ethanol through it first to get the whole thing cold) You would be amazed how much freezing everything as low as you can go will help with better color. The next thing I recommend for better color is to avoid excessive or any grinding if you can, will save you some extra chlorophyll in your extract.
Not really but I don’t think any extraction using ethanol does.
Fair enough, been my experience as well.
@Roguelab Lol! Ya gotta stop quoting me out of context, Man!
When using DRY biomass, there is NO need to freeze it prior to extraction. In fact,
freezing dry herb prior to extracting can be detrimental to the extraction, since…
Cold resin glands fall off easier, AND
Frozen solid resin takes longer to dissolve, AND
Frozen trichomes condense water out of the air onto their immense surface area!
Dry herb has very little heat capacity. This is the inverse experiment to prove it to yourself:
Try freezing a dry cotton ball and a wet cotton ball some time. Then take them out of the freezer, one into each hand, and see how cold they are after 5 seconds! Notice how fast the dry one heated up?
That means dry herb will NOT warm up cold ethanol by any appreciable degree.
However, notice how cold the wet cotton ball stays?
That means ANY water that is warmer than the ethanol (condensed humidity ice is 0°C; way warmer than -80°C) WILL add a shit ton of heat to the cold ethanol!
For the next time you “quote” me:
“CHILL the SOLVENT! AND, do NOT chill the BIOMASS!”
Oh wizard of wizards thank you
Please check my last cry for help
An intersting thingy
Speaking of dry what % of humidity of biomass are you thinking?
Since most folks don’t use moisture analyzers, @DocsCBD, my usual recommendation is at least 2 days with continuously moving air in layers no more than 12" thick, uncompressed, at less than 40% RH @ 75-79°F.
why not add the terps back after the vac oven purge? dont you lose a significant percentage fo terpenes to the vacuum? what does your test results come back at total terpene percent?
@Sebastian37 I’m sorry to dig back six months, but I am incredibly curious about how you centrifuge the terps out. Do you do anything to reduce the volume of the hydrosol before spinning it? I always wanted to try this but assumed I’d have an unrecoverable film of terps on a whole shitload of water.
Hi Sebastian37, Actually there are two primary steps to achieve higher quality while simultaneously improving on efficiency and less wear and tear on your equipment.
Working with “Live” flower, I recommend you utilize the Cryo-Trim™ method to trim your flower and hence produce the highest quality sugar-leaf. The Original Resinator has a patented system whereby you can inject liquid CO2 into the enclosed sealed chamber to 12 degrees. Roughly, the temperature of ‘ice cream’. This freezes the parameter leaves of your flower. During a very gentle rotation within the enclosed drum, the parameter leaves merely snap off due to the brittleness created by injecting the CO2. Produces awesome trim at a rate of approximately 1Lbs per minute rate without any blades to harm your precious flower.
Upon the completed run in about 10 minutes for each 7.5Lbs load, you’ll be able to scoop up the incredible sugar-leaf, unlike any other system. When the initial injection of CO2 is implemented, the trichomes and terpenes are literally frozen to the surface layer of the ‘leaf’ and ‘bio-mass’. Take the sugar-leaf and hold under cold conditions until you have 15Lbs. With the 15Lbs of sugar-lear, you can change the trim netting on The Original Resinator to a micron screen and load all the 15Lbs into the enclosed chamber. Now, lowering the temperature by injecting CO2 down to -65degrees and extending the process time, you’ll create extraordinary and high level extracts, including Kief crude. You have two options at this juncture. You can load the ‘Live’ Kief crude into your column stacks or cure it in a CannaFREEZ freeze dry~cure system in 16hrs to 24hrs., and call upon that material as you need for your feed stock for other downstream products your producing.
Sid, I am not currently in our Maryland facility due to the quarantine so I can’t give you the name of the machine we use to do the centrifuging of the terps. That being said, the process involves putting the collected terps and hydrosol into test tubes and then centrifuging it down. It separates everything out and we skim the terps off the top layer or we might scrape the hysdrosol off top, I forget but either way it separates it out for easy collection.
We do add the terps back in after vacuum purge. Our test results will vary depending on what purpose we are using it for and how much of the terps we put back in.
I have had problems with freeze dried material being less compactable than conventionally dried material. The same socks that would hold 5 lbs of conventional, I could only fit 2.5 lbs of freeze dried. Even after milling it.
It might be less weight after freeze dried, but it is actually equivalent to more material since all the water is removed hence the inability to compact.
No, the moisture content not different enough to account for that. The conventional material would have had to be 50% water to make up the difference. And it was not.
from some old weed from last harvest in Aug unfortunately I dont have the money for a close loop so I’m doing this with a open blast glass tube pre froze loaded tube n beutane in deep freezer this is just some of the things that I’ve read like I said I am new to this process and I’m looking to create a good golden colour honey oil but it hasn’t really worked out I just have a standard glass tube stainless bowl and a double boiler I would like to know what mistakes or what is the professional way of doing it with the equipment that I have for example what type of butane to use that will give the best clear golden colour honey oil and have a good taste no butane leftover
Basically I need some professional help I have done it a few times and have a good idea of what to do I just need to tweak it and maybe get a few Trade Secrets along the way that will really help me out I am sick of making large batches and I’m just being mediocre or altogether failures please help desperately
