So finally I collected all the items I need to setup my soxhlet extractor. Running my first setup extracting Rose Hips & Passion Flowers! Loving it this helps to save up on alcohol and also to create way more concentrated extractions.
Will be creating some powerful Spagyric Tinctures with this Baby. Not only can you create a super concentrated extraction but you can extract an herb in a matter of hours instead of macerating it for weeks on end.
Especially useful for being able to work on some projects, while waiting for others to macerate the gentle way.
So for a quick explanation of what is happening here, we have our lowest flask filled with alcohol 96%. This then boils and climbs up the leftmost tube as vapor and gets cooled down at the top by the water-cooled spiral condenser.
The alcohol then drips down onto the herb and fills up the middle chamber, once it is full the smaller tube empties out the entire mid-chamber back into the lowest flask.
Then the alcohol is distilled off again and what was extracted remains in the flask below, while the alcohol vapor goes back up and extracts the plant material some more. We repeat this until the alcohol in the middle chamber no longer takes on any color from the herb, showing that the material is spent and everything was extracted.
For my more refined projects I am waiting on a steaming-flask which will allow me to steam distill the essential oils and hydrosols of the plants & flowers I work with.
I’ve done steam distillations in the past using a simple method in which I boiled the herbs in the same flask as the water, but it would burn too easily the oils.
I leave you finally with a short video, where you can witness the threshold being reached in which the whole mid chamber empties itself out into the bottom flask.
Love this Moment!
