Feeder Plays Integral Role in Automated Pre-Roll Cannabis Equipment

Just as it is affecting many other verticals, a tight labor market is also impacting the emerging cannabis industry, especially in typically manual processes like pre-roll production. Lately, automation is becoming more sophisticated to fill the gap.

The machine’s recipe approach allows operators to easily adjust specs to different flower strains through compacting and twisting to produce consistent shape with uniform density.
The machine’s recipe approach allows operators to easily adjust specs to different flower strains through compacting and twisting to produce consistent shape with uniform density.

The legal cannabis market is forecasted to reach $41.6 billion by 2025, as more than 36 states have already made recreational or medical cannabis legal, and additional legalization efforts are underway across the nation.  

Machine builder Accelerant Manufacturing co-founder Grant Schuster and his team looked at the cannabis pre-roll cone joints market and noticed that pre-rolled marijuana products are outperforming overall market growth. The Maryland-based company saw an opportunity to use automation to meet demand, and began work on cannabis pre-roll equipment to meet the niche demand. 

“We observed that pre-rolled product sales grew 47% year-over-year in established markets in 2020,” Schuster says. “The problem is that operators cannot hire, train, and retain labor to keep up with demand. In response, our early research and development efforts proved that automation could produce up to 2,000 pre-rolls per hour and repurpose the 15 to 20 people needed to produce the same output.” The Accelerant PRO Modular System incorporates an Eriez 6C electromagnetic vibratory feeder that handles 500 to 2,000 cannabis pre-rolls per hour and is accurate to 0.01g – and it’s never underweight the company says.The Accelerant PRO Modular System incorporates an Eriez 6C electromagnetic vibratory feeder that handles 500 to 2,000 cannabis pre-rolls per hour and is accurate to 0.01g – and it’s never underweight the company says.

Accelerant contacted integrator Cutting Edge Automation to help move the effort forward. Together, they developed what would become Accelerant’s Pro Modular System. Inclusion of an Eriez® 6C electromagnetic vibratory feeder was critical to the success of pre-rolling and reducing waste.

The Eriez feeder handles 500 to 2,000 pre-rolls per hour. The weigh filling system is accurate to .01 g, and is never underweight according to the company., 

This light capacity feeder enhances compacting and serves as an ideal component within this demanding operation where small quantities of cannabis is required, and consistent shape and uniform density is crucial.

The 6C electromagnetic feeder--ideally suited for precise material metering applications--features a stainless-steel tray. The enclosed vibratory feeder drive is designed to operate in dusty and wet environments.  When paired with the Unicon solid-state feeder control, superior feed rate control is achievable. The Eriez 6C electromagnetic vibratory feeder meets United States Department of Agriculture (USDA) requirements.
