I’ve heard of people having better success with other gases I think. Like co2 I wanna say. This method always seemed to promote undesirables in the hash. But I do not doubt with the right R&D team this machine could be viable. I just always stuck with what I know works esp with other peoples money lol
Gas expansion is definitely a tricky one for this. My only concerns would be the same having a unit that doesn’t have all the bells and whistles you’d need to function efficiently. With it coming from the bottom and creating bubbles that break apart the bio mass would be my main concern other than having to wash the trichomes that get stuck atop the wash once ready for collection. This can be avoided with a spray bar I’m sure but also would be beneficial to have a set screen the hash itself could fall below and from the screen on each corner have a emitter that would then cause the propulsion for mixing. I feel that would be better as then you could Al pst quite literally have a continuous wash loop of the batch that’s in.
As for the gas expansion it’s a fine tuned tech that will have to be controlled on a few variables of course as every batch of bio will differ in its own way. But it will be determined upon r&d of course. I played with something similar hand washing years ago, I would put a couple palm sized chunks of DI in the bottom of my wash bucket below screens while washing when I would do them all in one bucket with the work bag. It would make some of the nicest hash due to temps, but wasn’t as controllable as it could have been with something like this unit here. Yields were low due to the material I was using but the quality came out a bit better for what it was.
Ya I’ve got another consult coming up and the client is really sold on this system from Wacky Willy and i just dont have any solid data to report on its efficacy. The price tag, jacketed wash vessel and included chilller is what’s attracting the client.
They make the Icon right? Heard great things about that unit.
I’ll check it out. I’ve only used Pure Pressure Axis Separator, Low Temp Osprey, Delta Separations Vortex Separator, obviously Bubble Magic washers and then a few custom builds (both manual stir and china fuge style).
We tried air spargers reluctantly. They did not work. Engineers warned me, but we tried anyways.
The issue with spargers is that they are typically made to suspend solids off the bottom of tanks like when solids are heavy (think sand) and not to agitate. Air is loud and more energy intensive than a motor to agitate. It volatilizes terpenes. Most importantly it is not an effective method to remove heads from biomass. There are way better methods to do it.
Lastly, why spend 20k for a 75-gallon machine when you can get a Mesclatore Lite for $15k that can wash 35 pounds of FF on a 100-gallon tank? That’s my 2 cents.
So the air agitation comes from the base of the vessel, as expected, entering from 4 air inlets into the slurry. IMO from the visual demonstration it does not sufficiently agitate the contents of the vessel. Air rises without circulation, obviously, so only the biomass in the direct path of the inlets is agitated. Additionally there is no circulation from a stirring mechanism or vortex.
What I did like about his vibratory collection vessels was the mounting of the vibration motor on the underside of the base. Instead of on the side of the vessels, like I’ve seen some, so the vibration should be more evenly distributed throughout the vessel.
Willy also uses this mechanical arm that has a mash plate (perforated ss disc) mounted above the vessel that can be used to submerge the biomass in the water at desired intervals to saturate it thoroughly.
But to surmise I still am not sold on air injection being a viable alternative to mechanical stirring.
