Best Icewater Hash System on the market?

I use to use a conical fermentor with an air line for agitation then drained through staged bags. Worked really good, especially 12+ yrs ago


How do you get around the heat of the air compressor?

We used to use co2 like that in a conical fermenter. Helped with the heat but would clog with dry ice from time to time


I’m sure nitrogen would be a good alternative


Totally agree, this was 5+ years ago

Hey guys, check out this video on YouTube about agitators used in solventless machines, some of which are described in this thread.

Take the video for what it is, as it is not a scientific study. It is a simplistic explanation of the importance of agitator and vessel design and how different designs affect fluid dynamics. I welcome you all to replicate and validate our claims. My goal here is at least to entertain and hopefully teach.

My opinion is that our machine, hands down, is the best machine on the planet. We took the time to design a fantastic system and are not scared to make those claims here. As I have learned, some people here are brutal and have way too much time on their hands. :joy: but I got a bag of popcorn, beer, and cigars.

Yes, our machine is not cheap and it is not for everyone. Enjoy the video!


Nice video. Have you considered funding a study? It wouldn’t cost a ton for a University study using three-dimensional computational fluid dynamics (CDF) models and subsequent validation. There are programs available where the Uni may pay half the cost. You already have the 3-D printed vaned disk turbine impellers (Osprey and Mesclatore) and the higher shear radial flat blade paddle impellers.

Here’s a good article in Processing Magazine:
How computational fluid dynamics is applied to mixer design

Have you considered adding using dual-impellers, for example, a radial flat plant paddle impeller near the surface for greater interface agitation, offsetting your impeller, or baffles to your square tank? A CDF analysis of baffles on square and round agitation tanks would be interesting.

I’m considering your Magna Agitatore. But first, I’d like to see a video of it in use. I’m sure many other people would as well!

Specifically the efficacy of the deck sieves with different screen sizes and harvesting the trichomes from the collection screens socks.


We will be doing demos all summer. Hopefully, we get invited to some of the more reputable or recognizable brands so stay tuned. If anyone works for or consults/has contacts with a big name please reach out.

The sieve system will be featured this summer and hopefully, the demos convince the industry of its application. I feel strongly about sieves and I implore companies to stop reinventing the wheel. Buy a sieve from us or the dozens of fantastic US manufacturers that know what they are doing!

Yeah that’s about the coolest thing I’ve seen in awhile, seems like a great way to increase throughput


If I can talk to someone who has used it or see a video of it in use I’m buying it. are any units in the wild? What has been the feed back been so far? And is that your first iteration (I don’t like being an alpha tester, lol)?

Great post! So yes we did lots of CFD. Everything you see in the videos we learned from CFD or DEM simulations. We don’t post that work because it costs an arm and a leg if you have to rely on an expert to help you. Publishing that information gives competitors education and is something they need to invest in if they want to get into the game. No sense in making their life easy.

We did reach out to several universities. For the electrostatic separator we are developing, we reached out to a university and yes they would help but it would de 18-24 months before any research would be published. It has to do with their semester scheduling and PHD candidates etc… For us, the cost savings do not merit the long time frame. What we do instead is hire a teacher and some PHD students and have them liaison with my team in Italy. They explain the theory and engineering drafts and propose solutions. Those get prototyped and tested until something final pops up.

With the Mesclatore we worked out a round tank cause it’s cheaper to make and we already make several hundred a month. DEM suggested it would be great but it proved challenging. This is why you not only make models to verify CFD but also prototype to validate.

There are 3 long and boring YouTube videos that cover the design process in depth including some of the roadblocks we hit. We did try baffles, dual impellers, and so much more on our round tank. We already know the answer to all those questions. At some point, we will publish the findings but in the meantime, others should give it a go.

For now, my goal is to educate why our system is different and leave it to the user to decide whether it’s for them or not.


We did R&D and developed an SOP with Vibrowest and Justin at Green Mountian. We filmed a video with his system a few months ago. It gives you a basic idea of how it works.

Justin had it nailed down. We just went back and forth with Vibrowest on how to make it better and improve the workflow which he already did well.

Justin has a basic sieve with a vibrator on it. Hash piles on the side opposite to the motor. Even 2 motor designs aren’t that effective. A rotary vibrating screen that circulates is the most efficient way to do it. You are limited by the diameter of the sieve, and how many decks you can stack. But with the right SOP the workflow is as efficient as possible.

There is no beta testing really. These systems have been around longer that we have. The SOP was more important than the machine. We will be testing a US made sieve this summer, exact copy of the Vibrowest, simply because logistics are so crazy. You will see the whole system in action this summer and in person at MJBIZCON Booth 9031.


Wow, that’s awesome! I’m impressed with your level of R&D and retaining the services of experts. Fluid dynamics is an advanced field of science, and it’s not something one can jump into and make a product in the same week. It’s nice to see you thought it through so well and tried various designs (validation) rather than just CDF modeling. :sunglasses:

I think you just secured a complete system sale…once I get to see a video of it in action :metal:

I thought the Mesclatore has a squre vessel (trolly?).

I watched the video, but it’s not the same system. I know the concept and physics are the same, but it’s far from the current design of the Magna Agitatore.

I have to strongly disagree that beta testing isn’t essential for a $24,000 piece of equipment. Sure, you’re not beta testing the physics, but this is what I’m concerned about:

How well the trichome slurry will move from the deck sieves into chute and then the sock screens for final collection without user interaction. I would expect the real-world use to function exactly as shown in the animation. I don’t want to be forced to stop the unit every few minutes and manually scrape the deck screens into the chute. I am a little concerned about the sock screens’ ease of use and efficacy.

I want to see on video someone using it, then open up the decks to show the material left on the screens. And I want to see someone open the sock screen vessel and show the removal of the socks.

I’m not attending MJBIZCON. I’ve been to enough in my life never to go again, lol.

Why not get some fresh hop cones or hemp flower and let it rip on video? Open up the system and let us see the result?

Considering I’m very likely to spend $66,500 on your system (with an extra trolly), I don’t think that’s too much to ask. Especially considering you haven’t tested the US-made sieve decks. Do you?

I’m not trying to ride you, but you’re asking for an awful lot of trust and faith in an untested product. And I’m not too fond of gambling…

Bring it down to socal.

We have a 10x10 cold room.

We make the hash for a lot of Wonderbrett products.


It does. But we made a round tank first. CFD showed promising results but ergonomics of use were some of the setbacks. Instead of adding baffles and fixing a few things on it, we modeled other shapes. When working with plastics we have so much flexibility as to shape.

OK, I see what you mean. Yes, you are right there are some things that need to be worked out. The sieve itself doesn’t need testing but the whole system does. It will all make sense when you see the videos of the demos. You can decide to run batch or continuous, and depending on your material you may need to sort sizes after the wash is done.

The problem with these sieves is that you cannot stack more than 3 decks. If you are sifting more than 3 sizes, which most are, you have to reprocess several times. The SOP takes this into account. Also, you have to physically look at your hash when washing and rinsing, so the setup is made to allow this.

I hear ya. But whatever we claim it’s best to prove. Stay tuned on YouTube for those videos!

For sure there will be plenty of biomass to run and film the entire process.


Awesome, I can’t wait to learn more! Congratulations on what looks like a very slick and well-thought-out design.


If you want to play with computational fluid dynamics on the cheap - BitTorrent a copy of COMSOL multiphysics and do a tutorial on how to use it.


What do you guys do with the soaking wet plant material after?

On A. Local code, B. Volume, and C. On-site capabilities

We just rinse it down thoroughly on last wash and drain then double bag and place in trash bins that the city picks up next day after being called.

Most jurisdictions make you use medi-waste or similar. Or a service like growkashi
