Welcome to the first episode of the Pre-Roll Automation Podcast, a new ongoing series where we go behind the scenes of Accelerant's engineering, manufacturing, and production floor to talk about what actually separates automated pre-roll systems from one another.

In this episode, we dig into two of the questions we hear most from operators evaluating automation: what actually makes a pre-roll machine's output consistent, cone after cone, and how much a system can really be tailored to a specific product profile. The conversation covers how Accelerant's air compaction technology corrects for imperfect or damaged cones, how operators can fine-tune fill "recipes" for entirely different product lines on the same machine, and why domestic cone manufacturing through Swiss Cones is becoming a bigger part of that equation.

What makes the PRO2's air compaction different

Traditional pre-roll automation relies heavily on mechanical rod tamping to pack flower down into a paper cone. For experienced operators, the downsides of this old method are clear: rod tamping frequently tears papers, creates dense pockets that restrict airflow, and causes high waste from bent or crushed crutches.

The innovationThe PRO2 introduces a patent-pending Air Compaction technology. By utilizing a tailored "Fast-First / Slow-Final" weight-based fill alongside targeted air pulses and micro-vibrations, the machine settles material uniformly.

The PRO2 also incorporates a pre-fill Cone-Expansion and Correction step. Before a single grain of flower drops, the machine physically expands and re-forms the paper. If cones arrive warped, compressed, or misshapen from transit, the PRO2 automatically corrects the structural integrity of the cones — reducing mechanical failures and helping ensure a flawless burn, regardless of whether you source paper from multiple vendors or transport materials between facilities.

Recipe programming: one machine, multiple product lines

A common myth about automation is that machines are rigid and only work well with one specific strain or moisture content. The PRO2 disproves this through advanced recipe programming. Every variable of the filling process — air pulse intervals, exact PSI settings, vibration frequencies, and precise target weights — can be configured, saved, and locked into a dedicated SKU profile on the machine's software.

• SKU customization — Operators can program a dense, firm pack for a standard 0.5g pre-roll line, and immediately switch to a softer, higher-airflow pack configuration for a premium 1.5g infused blunt.
• Tool-less changeovers — Transitioning the physical hardware between different sizes, such as moving from a standard King 109mm cone to a high-volume PRO120 spec, uses the fastest tool-less changeover system in the industry.

This level of granular control enables multi-SKU brands and contract or white-label manufacturers to run distinct client profiles back-to-back with total product uniformity across different facility locations.

What's next: 360° vision quality control

Accelerant's engineering roadmap is constantly moving forward. Currently on deck is an advanced, automated 360° Visual Inspection and Quality Control system. Using multiple laser line scanners, depth sensors, and AI-driven imaging, this integrated step will automatically analyze completed units in real time, instantly segregating outliers while collecting rich environmental data — batch numbers, active operators, machine temperatures, and room humidity. It moves facilities closer to a fully touchless, smart ecosystem: fill, coat, inspect, package.

Key takeaways

• Air over rods — Patent-pending air compaction eliminates the broken papers and bent crutches caused by traditional mechanical rod-tamping.
• True SKU flexibility — Onboard recipe programming saves custom settings for radically different flower types and dimensions, with zero-tool changeovers.
• Domestic reliability — Swiss Cones removes supply chain friction with precision, machine-made domestic manufacturing in Iowa and low custom laser-engraving MOQs.
• Zero CapEx growth — The Production-as-a-Service model gives you access to equipment capable of hitting over 2,100 units per hour without upfront equipment costs.
