Over the past few years, the pre-roll market has expanded exponentially. While those in the industry can likely attest to this trend through anecdotal experience, the increase in pre-roll sales is undeniably significant. Pre-rolls now hold the title of the second-largest growth segment out of all cannabis products on the market, outpaced only by flower. Consumers are showcasing their demand for both pre-roll packs and higher-priced infused pre-rolls. Sales of infused pre-rolls doubled in both 2020 and 2021, and pre-roll packs accounted for nearly half of all pre-roll sales in 2021.

These trends have compelled 95 percent of United States pre-roll brands to implement expansion plans. Packing pre-rolls on a commercial scale has presented challenges throughout the history of the industry because the technology available to automate high-quality pre-roll production was lacking. Fortunately, engineers who specialize in processing plant matter for smoking have demonstrated the industry’s ability to innovate in a short amount of time. The industrial machines on the market today fill thousands of precisely measured pre-rolls in a single hour. These technological feats integrate with other post-harvest processing systems and allow for key customizations and performance with more precision than the human hand. The machines to which we now have access create significant long-term cost savings, yield higher sales prices, and create better margins for businesses.


Given the degree of consumer spending on flower, procuring even a small share of the billion-dollar category can be highly lucrative. The numerous pre-roll brands across the country have an opportunity to gain a competitive edge in an emerging market niche. Currently, there are more than 600 pre-roll labels operating nationally without any single brand dominating more than three percent of the market. The most beneficial time for businesses to invest in expansion and improvement of production with one of the best pre-roll machines may be this exact moment in the industry’s evolution.

JuanaRoll by Canapa – up to 4,000 per hour

Canapa’s innovative eight-channel JuanaRoll automated pre-roll machine includes cone-no-fill detection and a cone open camera vision system. The machine’s camera vision integration is part of its user-friendly HMI which enables businesses to create unlimited recipe setups and provides easy control over compaction and twisting. Real-time production reporting can be displayed at the touch of a button and data is easily exported via email or USB. The included online support cameras, filter-in-place detection, and integrated how-to videos make the JuanaRoll a particularly user-friendly machine.

In addition to its user-friendly features, the JuanaRoll is a highly customizable pre-rolled cone filling machine. It offers three different options for cone presentation; the JuanaRoll can twist, twist and trim, or crown pre-rolls after they have been filled. The JuanaRoll can be outfitted to include an automatic trimmer, a second compaction station, and a cone changeover kit. It is also available in four-, six-, and eight-channel configurations. These customization options can significantly reduce the need for manual labor and the length of processing time. Cost estimates for each customer’s JuanaRoll system are determined on an individual basis.

GreenBroz Holy Roller – up to 3,000 per hour

GreenBroz has earned industry-wide recognition for its post-harvest processing equipment with awards to back it up, and its engineers have been hard at work developing the company’s first pre-roll filling machine, the Holy Roller. Most pre-roll machines feature standard rotary tables and square footprints, but GreenBroz stands out with its new inline design, developed to increase throughput and accuracy. To ensure precision, the Holy Roller also features a unique fine fill station, an active weighing system that lifts the cone out of the holder and weighs it independently before “fine filling” within .001 of a gram.

Not only does the Holy Roller fill and tamp simultaneously, the machine automatically separates underweight joints to a rejection station for easy recycling. Users will also enjoy flexibility and ease of use with the machine’s ability to pack any size joint using the same paper cone. While the Holy Roller can be integrated with other systems, its accuracy and efficiency are optimized when the flower is ground by the GreenBroz Model G Precision Grinder. When a business purchases a pre-roll machine from GreenBroz, the same engineers who designed the technology will help with setup and training to ensure customers get the most out of their pre-roll production. The Holy Roller will be available soon in 2022.

Knockbox by Futurola – up to 2,000 per hour

The Knockbox by Futdurola is easy to set up, easy to customize, and fairly affordable with a retail price at around $5,625.

Futurola’s pre-roll machine is compatible with 16 varieties of Futurola pre-rolled cones that range in size from 0.5-gram pre-rolled cones up to 2-gram pre-rolled cones.

To pack the cones, the Futurola Knockbox uses a tamping system that bounces the cones up and down while lightly tapping the crutches of the papers during filling. The unloading feature on the machine and its vibrating design ensure a compact cone without air pockets. There are a range of attachments and accessories available to enhance the packing process, such as 4 different variations of filling kits, half-size mix trays for specialty cones, and cone loaders.

PreRoll-ER 200 – 1,500 per hour

The PreRoll-ER 200 works with all types of strains and infused joints in both conical and cylindrical pre-rolls. As an optional addition, the manufacturers also offer a direct oil injection system. PreRoll-ER guarantees a tolerance of 0.01 grams by weighing before and after filling with its Exit Weight Checking and Reject Station. With its advanced PLC and HMI control panel, the joint filling machine provides extensive statistical data on production that can be used to improve operations.

PreRoll-ER claims the machine can replace 15 to 20 operators per shift, producing a rapid ROI with its auto-loading cone feature that requires no manual handling. There is also a video gallery on maintenance and operation procedures as well as an accessible support team available to help users keep their pre-roll production running smoothly. This summer, the company won the 2022 award for best packaging equipment at the O’Cannabiz Industry Awards Gala.
