Ultrasonic extraction. Low or zero solvent faster extraction

Hes something else thats been around for a little while and will soon be carving out its niche in the cannabis industry so we may as well start talking about it now.
Anyone have any knowledge or experience
Ive theorized on using ultrasonic on my soxhlet and how i might modify one for it but what do you know, someone already invented it for me.
Yay science!

Powerful ultrasound increases the mass transfer between sample and solvent. Thereby, solvent use can be reduced or completely avoided. The extraction duration is drastically shortened so that the extracts are not exposed to long heating period. This means that decomposition of the extract can be avoided

Another way to say it is that the extraction time is shortened using ultrasonics, while the material and solute is being subjected to solvent at its boiling point. Ostensibly it would need to be done under vacuum, to keep boiling temperatures lower than the point of separation of the carboxyl group.

Recycling the solvent in a soxhlet reduces the required volume, but how do you "avoid solvent" in a soxhlet??

Soxhleting with a polar solvent brings copious chlorophyll into play, and with a non polar solvent, fats, lipids, and waxes.

We absolutely get the greatest volume of "raw oleoresin" extract using a soxhlet, but the percent concentration of our targeted fractions are very low.

The non targeted elements aren't all that easy to remove, while retaining C-10 through C-22 targeted fractions and divorcing yourself of the solvent, as well as heavier fractions like the about ~C-30 fats, waxes.

We successfully used a jewelers ultrasonic jewelry cleaning tank to speed up vegetable glycerine extraction, and subsonic vibration in a closed tube of butane and plant material to speed extraction rates.

I dreamed of speeding up the Grinning Reaper inexpensively, and hooked up a relatively cheeep 60W transducer mit driver, to see about how much effect it had, but alas it was seriously under capacity, and larger transducers and drivers get expensive fast, sooooo I gave up on my "relatively cheeep dream."

Glad to hear cuz that was my DIY tec i was going to try. I was going to take apart a bath and fasion a probe that suited my needs. Ive always had mixed success with repurposing other tools for my needs. I wondered if a jewelry bath was strong enough DB
These units pictures above i belive are more fine tuned for extraction and are used to make lots of stuff non cannabis.

Don't give up though
Most of my first attempts at something new dont go 100% perfect or end in complete failure.
