Hello Everyone,
I am in need of some information on how Steam Terpene Distillation works from cannabis flower,
one of my questions is what is the minimal temperature at what you should be boiling the water to extract your terpenes , let me add in that we are currently not trying to isolate just one certain terpene at the moment but just get the right gauge on what and how we should be doing this to just get a good amount of terpenes , we currently are using a goldleaf scientific steam distillation kit to extract terpenes we have done maybe about 6 runs and found that we have not gotten the results that we thought we were going to get, here are a few specs on the current Process
Mantle set to 60°c
Flower Resevoir 2000ml Filled Halfway
Chiller set to Freezing (Sorry i am not at the Lab and i Cannot Remember what it is Set to).
if i could receive any information on the different temperatures and different methods that people have found viable to use please send them my way.
Thank you everyone for Helping!!!

For steam distillation to work without vacuum, you need steam. steam is 100c. As long as your boiling flask is full, it wont go above 100c. so set it to 120, Also, go grab my Free Steam Distillation SOP at General SOP Lists — Gemstone Botanicals

Hello @Psilisophical Thank you for responding and thank you for that SOP i really appreciate it.
So we are currently using a Diaphragm pump i am sorry i forgot to add this into the specs.
The Pump is going to be KNF Lab Filtration Pump.
is this going to work with the same method you have responded with since we are using a vacuum?
We have the Chiller set to 39° fahrenheit.
Vacuum distillation is a little more difficult with the same glassware, you need to either seal your hydrosol collection vessel to the tube that feeds it and pull from the vapor transfer tube atop, or just collect everything into a boiling flask, and then redistill that collection into the good oil/water separator. If you go with the former method you have to pull vac very slowly or else the air rushing through the oil/water separator will get pushed around too much and youll lose significant yeild
Did you ever dial this set up in. Am thinking of buying same one for cannabis terpene essential oil
