I have been trying to build a table, for purge time, temperature and pressure. This is what I have found so far. Please make comments for adjustments or additions. BTW, there are 50 words in the eskimo language, for snow. I bet that the pot culture has more names for extracted oil. The names that I use below are general classes.
The method of extraction will determine the solvents that remain in our concentrates. I understand that the solvent to be purged will affect each process, so some tweaking is expected. The starting material should already concentrated, and thick.
**TEMPERATURES for purging:**
Live Resin: Extract from fresh material should be used. 70 degrees F @ low vacuum (25mm) for 72 hours, not heated, runny with very high terpene content
Diamonds: (THCA crystals) multi-step. Extract from fresh material should be used. Initial purge @ 85-90 degree F with no vacuum for 1 hour, followed by 3 weeks of open, undisturbed rest @ room temp. Use ultra-clean glass. Separate crystals and liquid terpenes. Purge @ room temp using high vacuum. Liquid for 60 hours, crystals for 72 hours. Recombine
Shatter: 90-100 degrees F @ high vacuum (30mm) for ~100 hours, mild heat, solid and glassy
Budder: 100-125 degrees F @ high vacuum (30mm) for 72 hours, medium heat, softer, like fudge
Crumble (honeycomb): 125-140 degrees F @ low vacuum (25mm) for 72 hours, higher heat, dry and crumbly
Honey Oil: 140-180 degrees F @ low vacuum (25mm) for 72 hours, highest heat, syrup-like
OK…there it is…in temp order, low to high…extract consistency from hard to liquid.
Please comment and expand.
