A pre roll cone filling machine is automated cannabis production equipment that fills pre-rolled cones with ground cannabis flower at high speed while maintaining consistent weight, density, and compliance standards.
The Mini-RocketBox+ uses a nitrogen-filled airbag fluidization system to fill cones from the bottom up - no pre-weighing required. It fills 143 cones in 30-45 seconds. The Futurola Knockbox 100 fills 100 cones in a minimum of 2 minutes and requires pre-weighing before every run.

Plastic knockboxes break. King Kone fills are inconsistent. Hand-packing hemorrhages labor. If you are producing pre-rolls with any of these methods, you are losing money on every shift.
Knockboxes and King Kones are built from plastic not designed for daily commercial use. When they break, your line stops.
Vibration-based machines do not level cones from the bottom. Weights drift. You over-fill and waste flower or under-fill and fail compliance.
The Futurola Knockbox requires pre-weighing before every run. That step adds labor time and operator variation before filling even starts.
A knockbox or King Kone is a dead end. No closing machine integrates with it. When you are ready to scale, you replace everything.
Two hand-packers at 5,000 pre-rolls per day cost $57,000 to $80,000 per year. The Mini-RocketBox+ replaces both at $6,600 - payback in 4 to 8 weeks.*
New to pre-roll production? The Mini-RocketBox+ is the lowest-risk entry point into commercial automation with a clear upgrade path when you are ready.
Stainless steel and aluminum construction. The patented lift plate levels cones from the bottom while the adjustable top tray meters material - no pre-weighing required, consistent weights every batch. At $6,600 it is the most affordable metal-built pre roll cone filling machine on the market. Ready to close? Add the Atomic Closer and you have a complete fill-and-close line.

Up to 143 cones in 30-45 seconds - up to 1,250+ per hour with one operator.
The lift plate and nitrogen airbag system fill every cone consistently - no operator pre-weighing, no variation.
At 5,000 pre-rolls/day two hand-packers cost $57,000-$80,000/yr. The Mini-RocketBox Plus+ replaces both at $6,600.*
SAE 304 stainless steel and aluminum - not the plastic components that crack and fail on knockboxes and King Kones.

All three machines sit in a similar price range. The difference shows up the moment you run a cycle: 143 cones in 45 seconds with no pre-weighing on the Mini-RocketBox Plus+, versus 100 cones in 2.5 minutes on the Knockbox 100, and ~1,000 per hour on the King Kone with pre-weighing required. That gap compounds across every shift, every day.
