STM Canna RocketBox 2.0 Pre-Roll Cone Filling Machine

RocketBox technology creates varying frequencies of vibration that are concentrated in the bottom cone holding tray. Versus shaking, this method allows for the material itself to vibrate down evenly layer by layer into each cone –avoiding air pockets, weak necks and other inconsistencies.

There are 3 cycle stages, each with 3 fully customizable settings: PSI (20-90), Motor Speed (1%-100%), and Duration – all allowing the operator to work with a variety of different material types, densities, and strains and achieve desired results.

Beginning with the cone tray suspended in air during the cycle, the first stage (“filling”) starts by emitting light vibrations to agitate the material and begin layering itself in the cone.

The second stage (“packing”) then emits more intense vibrations and a bounce to pack the pre-roll.

Stage three (“optional final pack”) is optional.

Aside from a wide range of customizations, the unique RocketBox tray system includes funnels that directly taper inside of the papers below, allowing for better weight accuracy, fill rates, product quality, and consistency.

Yes. The general weight variance is 10% +/-, which we help you dial-in further with training and bulk density testing. Each bottom tray size has its own range of weights that can be achieved with each paper size (see Compatible Cones page within brochure). You can dial-in your weight further by adjusting your grind size, paper size and/or machine settings

RocketBox fills and packs up to 453 pre-rolls every 2-3 minutes, while the Mini-RocketBox fills and packs 143 pre-rolls every 45 seconds.

The RocketBox is constructed of 304 Food-Grade Stainless Steel, with certain accessories being food-grade and industrial aluminum/plastic. Technical documents and information can also be found here in the STM Dropbox folder.

While some companies twist the ends, we highly recommend against twisting the end as it creates issues of canoeing/running (uneven burning down one side). Twisted joints can also vary in appearance & height from one to the next and become less suitable for packaging. Our preferred method is the Dutch Crown (a flat, almost crown-like appearance) which is quicker and allows the user to ignite the joint like a cigar for a smooth, even burning pre-roll. 

Each Bottom Tray is designated for a specific industry standard size paper (see the Compatible Cones page on the brochure for specific measurements). Any reputable, quality paper brand can be used so long as the cone is a compatible size. 

• • .5g/84 MM Bottom Tray = 1-1/4″ Size
  • .7g/98 MM Bottom Tray = 98 MM Special
  • 1g/109 MM Bottom Tray = King Size

***Please note, the Mini-RocketBox is not compatible with Cigarettes, Reefer or Slim Sizes.

Yes. The motor (vibrations) can be set between 1%-100%, typically on the higher end. You can also alter the PSI in conjunction with the motor to adjust the bounce and for tighter or looser vibrations.

The RocketBox is only compatible with cone-shaped papers. Our proprietary two-tray system is set up so that the cones sit snug in the cone slots in order to remain suspended in air during the cycle, whereas a cigarette/skinny cylinder would fall right through the slot.

Dropping Cones: 5-10 mins
Machine Cycle: 3 mins
Loading/Unloading Trays: 1-2 mins
Total Prep, Fill & Pack Time: 15 mins max
Closing/Folding Ends: 175 pre-rolls closed per person per hour (average)

It’s about 4′ tall x 3.5′ wide (17” L X 48” H X 43” W).

STM takes safety very seriously.  While a machine itself cannot be GMP (Good Manufacturing Practices) certified, our machine is GMP compliant. We follow strict standards to meet OSHA compliance and use only the highest quality, commercial-grade components.

There are no special power requirements to operate the STM RocketBox. The RocketBox plugs into a standard 110v receptacle (like a home would have). It has a 15 amp breaker but only pulls about 5 amps (similar to a household vacuum). Additional technical documents and information can also be found here in the STM Products Dropbox folder.

With fast output and increased quality, the RocketBox eliminates tedious steps and allows you to achieve higher profit margins with lower labor costs and overhead.

The STM RocketBox machine in its entirety is not UL Listed, however, all parts and components of the machine are all OSHA compliant and listed under various listings. Please feel free to review the STM Dropbox folder as our RocketBox Listed Components sheet is available there for your reference.

Our machines are all up to the proper electrical standards that would allow you to make an appointment to have someone come out to certify your machine once it arrives in your facility. The 3rd party components of the machine are all UL certified or listed under CE or another listing.
