  • Filling Output: 1250/Hr, 10,000/Day
  • Centrifugal Nitrogen Fill: 44 ft-lb
  • 3-4x FASTER VS. KnockBox 100

Affordable pre-roll cone filling machine produces 10,000 joints daily with one operator using 44 ft lb centrifugal nitrogen fill.

You're either hand-filling cones and destroying your labor budget, or you've been told you need a $200,000 industrial machine to automate. Both are wrong. The RollCraft MRB delivers precise, repeatable fills on 10,000 pre-rolls daily with one operator paying for itself in weeks instead of years.

Powered by STM Canna's decade of engineering expertise, this aluminum-and-steel pre-roll machine runs 3 to 4 times faster than plastic alternatives like the KnockBox 100. The 44 ft lb centrifugal nitrogen fill combined with top tray and lift plate technology ensures accurate weights on every cycle without pre weighing or manual pulling. You load cones, the machine fills and packs them to perfect density, and you move directly to closing. 

Built in the USA with high-grade components designed for production environments, not hobby setups. When you're ready to scale, add the ATC closer to complete a modular system trusted by the top 20 U.S. cannabis brands. Stop wasting money on overpriced industrial equipment or underperforming plastic toys. This is the smartest entry into automated pre-roll production.

FAQs

What is the RollCraft MRB pre-roll filling machine?

The RollCraft MRB is a pre-roll filling machine built from the ground up for producers who are ready to scale without spending a fortune. For $3,500, you get a filler that handles up to 10,000 pre-rolls a day. Pair it with the RollCraft ATC Dutch crown closer and you have a complete automated production line for under $30K.

How does the MRB compare to hand packing?

A full-time hand packer produces roughly 500 to 800 joints a day at a labor cost of $28,800 to $40,000 a year. The MRB fills up to 10,000 pre-rolls daily with just 1 operator. That is not a gradual return on investment. It pays for itself in weeks.

How does the BRB fill? Do i need to pre-weigh my material?

No pre-weighing needed. The MRB uses pneumatic fluidization technology, a nitrogen-filled airbag leveling system that delivers consistent, precise fills that traditional tamping methods simply cannot replicate. Your material funnels through a patented, adjustable top tray that regulates fill volume on its own. Once the tray is full, all 72 cones fill to the exact same volume every single run. No overfilling, no underfilling, no guesswork.

Does the MRB include a closing module?

The MRB is your filling solution. For a complete end-to-end line, add the RollCraft ATC at $24,995. Bundle both together for $29,995 and you are fully set up from fill to finish.

What cone sizes does the MRB support?

The RollCraft MRB works with most major cone brands across all universal standard sizes: 70mm, 84mm, 98mm, and 109mm. If your cones are standard, the MRB handles them.
