Wow! Thank You! That will take a couple reads to fully digest but I cant wait to experiment. I have a stainless french press and some bromocresol green on the way for decarb. I’m sure I will have more questions.

You experience with lab test to back it up, I’m ok with not exact numbers. Thanks again.

my pleasure! hit me up with questions as they come to you, especially design of your infusion.

those stainless french presses are great for squeezing the leftover mct oil out

Ok it been a bit but I’ve been playing some. I started and Batsona Gave me some advise to I vectored mid way. Its ok, I’ll get the process down and become more efficient (wasting less oil etc). I am also inspired and want to try the perculation. Maybe in a month or so I’ll fabricate that up and start testing. In the mean time I’m using a aeropress. I started with the french press, but for the small batch sizes I’m starting off with it is very inneficient (7g biomass in a 32oz press with 50ml oil).

  • 28.35 g input flower 18%. Divided into (4) 7.09 g mini batches.
  • Each batch will have 3 washes of same initial biomass, noted “a”, “b”, & “c”.
  • Batch 1 & 2 fluid measure with Mason jar lines, not exact. Batches 3 & 4 fluid measures with 20 cc syringe for increased accuracy.
  • Batches 1 & 2 just broken up by hand. Batches 3 & 4 ground up much finer.

1a:

  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 125 ml input oil (Stock/Fresh Tank). Approx. 75 ml out into “High” tank.
    1b:
  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 40 ml input oil (Stock/Fresh Tank). Approx. 50 ml out into “Medium” tank.
    1c:
  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 35 ml input oil (Stock/Fresh Tank). Approx. 50 ml out into “Low” tank.
    Batch 1, Spent Biomass: 29.26 g.

2a:

  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 105 ml Input oil (75 ml High & 30 ml Medium). Approx. 70 ml out into “High” tank.
    2b:
  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 50 ml input oil (20 ml Med & 30 ml Low). Approx. 50 ml out into “Medium” tank.
    2c:
  • 55c oil temperature, 15 min steep time in 32 oz French press. Poor efficiency d/t vessel size.
  • 50 ml input oil (17 ml Low & 33 ml Stock). Approx. 75 ml out into “Low” tank.
    Batch 2, Spent Biomass: 27.3 g.

Aeropress Batches:
Batch 3: Following step 2 in Batsona SOP.
3a:

  • 55c oil temperature, 7 min steep time in aero press.
  • Attempted 27.6 ml input (30 g), but biomass not even fully saturated.
  • 50 ml Input oil (High Tank). 28.5 ml out into “Final” tank.
    3b:
  • 55c oil temperature, 7 min steep time in aero press.
  • 50 ml input oil (Medium Tank). 27 ml out into “High” tank.
    3c:
  • 55c oil temperature, 7 min steep time in aero press.
  • 32 ml input oil (Medium Tank last amount). 31 ml out into “Medium” tank.
    Batch 3, Spent Biomass: 19.43 g.

Batch 4: Following step 3 in Batsona SOP.
4a:

  • 55c oil temperature, 7 min steep time in aero press.
  • 40 ml Input oil (28 ml High & 12 ml Medium). 24 ml out into “High” tank.
    4b:
  • 55c oil temperature, 7 min steep time in aero press.
  • 27.5 ml input oil (19.5 ml Medium & 8 ml Low). 29 ml out into “High” tank.
    4c:
  • Got side tracked and didn’t do 3rd wash, though I did and threw biomass away after weighing puck.
    Batch 4, Spent Biomass: 17.60 g.

As you can see by input oil and final biomass weight that I’m getting better as I figure this out. So this is just a test batch.

French press, needed a lot of oil just to cover biomass:

I don’t think the Bromocresol green trick works on lipid infusions.

I’m sure it’s the oil not allowing the dye to mix.

Been decarb IMG 4hrs at 110c. I barely got any bubbles, not like a lot of the pictures and videos I’ve seen. But I’ll prob pull it anyhow.

what’s this?

and you’re not seeing bubbles because it’s dissolved in mct oil. pure extract will noticably bubble when you decarb it

89

its a test to check for full decarb.

yeah decarbing an infusion there is much less worry for things getting out of hand like there is with a concentrated crude. The bubbles should be pretty small, no bigger than 1 mm. At 110 to 115 degC you might get a flurry of activity as water is driven off and the reaction kicks up but it’s normal to not see much going on. Four hours at 110degC I would expect good conversion, at least 90%. But I routinely misjudge decarb times! Without any data my hunch is that it takes longer for less potent infusions to complete.

Unfortunately I have tried the beam test without any success on mct infusions… maybe there’s a way to modify method because I have definitely seen color changes when adding base to infusions.

yea i always found the only 100% indicator is when it stops bubbling after decarbing extract. but you can definitely do it in mct it just takes some r&d. you’re right it can get out of hand if you don’t release pressure regularly

93

Aweome, Thank You. I cant wait to try my next batch and see how much more efficient I can get.

In the mean time I sent the decarbed oil to the R&D department.

quite possibly. I failed to consider that aspect.

you may have to do an extraction/concentration step. that where speed vacs come in handy (requires a vac pump, and ideally a cold trap). not sure what the correct solvent would be for MCT.

your tincture may also be too dilute (that’s certainly why it didn’t bubble as vigorously as 70%+ cannabinoid material does).
