I have seen this machine in a tradeshow.
Unfortunately they did not have any terpenes sample to show the results.
It’s a microwave oven with a vaccum chamber inside.
That vacuum chamber is connected to a distillation column.
I’m not really convinced by microwaves until I can smell a sample…
I freeze dried fresh herb once, with an old unit. Only a portion of the profile is extracted that way. And the device smells for a long time afterward…
