Thanks for this input. We were looking at the 25 Pulverisette and have pretty much come to the same conclusion regarding wet material. Have you found a better system for dealing with wet biomass? We’re looking to reduce down to 1.5 - 2cm before drying biomass. Haven’t found a food grade stainless option that handles wet material well.
Unfortunately the company I was working for was getting directive from a third-party franchise holder and they dictated some of the equipment such as the mill. So there wasn’t much I could do about it. I’ve since moved on from the company so I never looked into a better alternative for wet material. Using that $30,000 piece of machinery to mill that was too wet was probably one of us frustrating things I’ve had to do in a very long time. So not worth the price tag

IMO not much point to a food grade stainless mill or grinder, especially if we’re talking about biomass destined for extraction. It’s almost guaranteed that between harvest and transportation it’s touched plenty of non-food-grade, carbon steel and painted surfaces.
I can see good reasons for food grade evaporation equipment and decarb vessels but it’s not like anyone’s out here making and selling food grade stainless harvesters or crop wagons for large scale operations.

Small scale - 1/8" hardware cloth for the win🤙

Agreed, but like every other crop, now that the government (USDA) is overseeing hemp, the regulations will continue to work deeper down the supply chain. We’re working with final goods manufacturers that will only buy from SQF-certified processors, who are in turn buying from farms that are SQF certified (farm-to-fork quality system). 2/3 or more of the hemp processors in the US will be out of business in the next 18-24 months IMO.
Why SQF vs GMP/ISO? There’s so many overlapping certs out there.

It really has to do with where you sit in the value chain and who you intend to sell to. International markets for example use BRC instead of SQF. GMP is at the bottom of the “Quality Pyramid” and you work up from there to more thorough and prescriptive QMS’s like ISO/FSSC 22000. We believe having only baseline certifications limits our pool of finished good manufacturers. SQF/BRC are rigorous and expensive, but are a valuable investment for our business. Here is an overview of the various certifications under GFSI.

It seems like the real money is in starting a certification company lol. Thank you for the link, i’ll definitely look into it. I’d hate to waste time/money on ISO only to find out we need BRC.

@KannaMill can get you consistent particle size with proper moisture % in the biomass, the right screen size within the Hammer mill, and air flow. We have two smaller lab scale Hammer mills that can get you what you need. Let me know if I can be of any help to everyone on this thread!
KannaMill 4 (100lbs/hr)
Thank god that thing is reasonably priced. The exact same concept is used in overpriced trim machines. Just stick a weed wacker in a 55 gal drum of biomass.

thats why i use a vacuum leaf mulcher. $77 dollars beats the shit out of a mill

Aren’t your mills like thousands of dollars?
Now i’m wondering if you can just lay plants down on concrete and run over them with a riding lawnmower equipped with mulching blades and a bagger lmao. (Don’t do this please, lol).

the problem is the guys doing this without the concrete…

Yes, that is correct. If you want inconsistent particle size, over-pulverized material, and slow processing speeds, then buy cheap.

Do you have side by side controlled studies to show that your mills result in improved extraction?
ok i will lol
No, but since launching our @KannaMill brand back in 2017, we haven’t heard of it being harmful to extraction.
