It all started last year when the Game Changer came out and it was enlightening, so I started to talk around about building one myself.
Talking to a fellow mixer that is an engineer that works with steel machinery and electronics, I explained the aim of the project, what it should do, we both agreed that had to be food grade stainless steel, high speed, extremely low tolerances (talking about microns between the stator and rotor)
He started the project straight away, pushed it even forward designing an all in one homogenizer.
After a few test we realized he made an extremely good instrument, with a 25000rpm motor direct drive, driven by a PWM controller, couldn’t ask for more, it worked perfectly oil and VG didn’t separate and things like that.
One morning I woke up and found out that my brain did the night shift!
We got the speed, we got the blades, we got extremely low tolerances, we’re forcing the liquid through the holes, what pressure is that at? Oh sh** it’s high pressure, we are actually sending the liquid into a cavitation with that much pressure.
Pressure? Cavitation? Tobacco ultrasound extraction is a cavitation process, why not try it!
I needed an expert with tobacco extraction made with ultrasonic so we could also compare the two.
I had an old friend that is a dedicated expert that only works with rare tobaccos and extraction, so I pulled him in and we started to do a few test with the homogenizer and compared the results with the ultrasonic extraction.
The results were amazing, not only it was comparable, but sometimes even better ( probably we retain the volatiles better, with ultrasonic you get a lot of heat and loose some volatiles, like it or not…).
Ultrasonic soon has become a thing of the past, the process is long, tedious, have to keep everything cool and need some cooling system, lots of cleaning, we make our own NET with the homogenizer in matter of minutes. the long process is the filtration, but you’d have to do it anyway.B
ut not only NET… think about coffee, teas and any natural pesticide free dried “thing”
From my point of view, a success!
For those who want to learn more about the process (bear in mind the Giorgio is not a tuber and goes deep into details) we made a video but had to split it into three parts.
Part 1 and 2 are already out, I burnt in the subtitles in English (YT doesn’t really do a good job on translating and it’s technical, so it’s even worst) part 3 will be out soon.
I’ll put the links below for those who want to learn more about it:
I have to thank Fabiano for the engineering and Giorgio for the lessons on NET ultrasonic extraction. Dan @anon36682625 for pushing the limits and I think I followed his steps and pushed it even forward, thanks mate!
