10 Reasons Why Businesses Chose the Preroll Centrifuge System
Jul 28, 2024
Selecting the right preroll machine for your preroll business is a crucial step in establishing a solid foundation for your production. When making this decision, it is important to consider your business needs and what you aim to achieve. In terms of efficiency, reliability, and profitability, the Preroll Centrifuge System stands out as the superior machine currently available. Let's explore the top 10 reasons why businesses choose this system over others, and why some have even switched or upgraded to this machine later on.
1. Packing with a centrifuge is simply better

When comparing all of the preroll machines available on the market, it's clear that every machine, aside from the Preroll Centrifuge System, utilizes a packing technology or process that is not necessarily ideal for handling cannabis. While these technologies or processes may work better for dry tobacco and cigarettes, it's important to remember that cannabis is a completely different plant with completely different attributes.
Ranking Best to Worst Preroll Packing Processes
1. Centrifuge Method (BEST OPTION)
2. Vibration Method
3. Filling Method
4. Rolling Method
The vibration method, used by many preroll machines, relies on shaking the cones to get the flower to fall into place. This creates many problems such as air pockets in the preroll, especially if the flower isn't cut into even particles.
The filling method is most widely used by the fully automated machines. These machines are quite large, and not mobile. They involve a lot of small components and moving parts, making it a very complicated machine that is more prone to problems in the future. Filling cones by dropping flower into them can cause the same quality assurance issues as the vibration method.
The rolling method in a way simulates how one would "roll a joint" at home, however the rolling process often causes more air pockets and only works with straight tubes, similar to cigarettes.
2. Centrifuge is Quiet
We were surprised to find out that one of the biggest complaints we heard from speaking with businesses utilizing other preroll machines was the operating noise levels.
Loud shaking and vibrating can certainly be disruptive to any work environment, especially if it's a constant noise. In fact, high decibels can be so disruptive that it may even create a hazardous workplace.
The preroll centrifuge system is a very quiet preroll machine, with just a couple moving parts, its operation is smooth, efficient, and makes for a much safer work environment.
Ranking Best to Worst for Noise Disruption
1. Centrifuge (MOST QUIET)
2. Fully Automated Machines
3. Vibration Machines
3. Scalability
Scalability refers to how efficient or simple it is to increase your production output rate while minimizing any increase in operational cost and liabilities. For example, with some preroll packing systems, the only way to increase production would be to purchase additional machines, which in most cases would mean increasing the production space and hiring additional labor as well. Based on our findings, the GPC preroll packing system is by far the most efficient way to scale production while limiting the increase in operating cost.
Ranking Best to Worst for Scalability
1. GPC Preroll Centrifuge System (BEST OPTION)
The GPC is the only preroll machine that can streamline production scalability from a single machine. Simply add operators to increase output, with not much need for additional space.
2. Vibration Systems (Knockboxes etc)
These systems are very popular as smaller and more affordable machines, however according to our customers these tend to break often due to the constant shaking over long periods of time. Having to replace systems frequently is very costly, and can cause more downtime where production is paused.
3. Fully Automated Machines
There are many pros to utilizing fully automated systems for preroll packing, however, while they can be quite enticing, one of their biggest fallbacks is their limited peak production capabilities. They have a maximum output which cannot be increased without purchasing another machine which costs a lot and takes up space.
Additionally, many of our customers who have switched to the GPC have expressed disappointment in the fully automated systems due to being complex, often breaking or requiring technical maintenance and hours of cleaning.
4. Preroll Density Control

From talking to so many customers, one of the biggest selling points with the GPC preroll centrifuge system is that it is the only preroll machine that offers full density control with every pack. As we mentioned before, cannabis is much more complex than tobacco, and making prerolls is a craft process much different from making cigarettes.
By controlling the density of your pack, you have the ability to control the quality of your pack, limiting air pockets and providing your customers with an even burn down to the crutch.
5. Preroll Air Pockets

One of the biggest problems consumers face when buying prerolls at their local dispensary, is the canoeing effect while they're smoking. Canoeing is when the preroll starts to burn down the side, rather than burning evenly at the tip.
Canoeing in a preroll is caused by having too many air pockets. As we mentioned before, by utilizing centrifugal force when packing your prerolls, you're able to eliminate most if not all air pockets. No other preroll machine is designed to be able to avoid air pockets, at least without damaging the cones themselves.
6. Long-Term Reliability

Reliability is by far one of the most important factors to consider when investing in the right production system. The last thing a business wants to face is extended downtime and the financial cost of frequent maintenance or system replacements.
The GPC preroll centrifuge system is the best system for long-term reliability and dependability. With less moving parts, its designed to perform for years to come with much less maintenance requirements as one would find from working with a fully automated all-in-one machine.
The preroll centrifuge essentially only has two core moving parts, the spinning function of the centrifuge itself which is operated by a single motor, and the arms or "talons" of the centrifuge which lift up during the spin cycle, much like the "Gravitron" carnival ride. Because of this simple design, this system operates very smooth and greatly reduces the amount of wear and tear that you would experience with other types of systems. Ultimately you will save thousands simply by not having to replace machines, and not having to deal with lengthy downtime.
Ranking Best to Worst Machines for Reliability
1. GPC Centrifuge System (BEST OPTION)
Less moving parts and components, with a single spin motion that remains sturdy and smooth while in operation.
2. Vibration Systems
Similar to the centrifuge, these machines don't have that many moving parts. They can last awhile if they're taken care of and used properly. However, they are still known to break and there is limited repair services available. If the machine breaks, you will likely need to just buy a new one.
3. Fully Automated Systems
These preroll machines are extremely complex. They have a lot of moving parts and small components. Since they "do it all" from one machine, there is a lot more room for error especially if one thing fails, the whole thing fails. These systems have been known to have lots of maintenance issues which cause a lot of downtime in production.
7. System Cleaning

Ultimately, the GPC preroll centrifuge system is low maintenance when compared to other preroll machines. The fully automated machines, or "all-in-one" machines have so many moving parts which means it could be quite difficult and extremely time consuming to maintain and clean. With the preroll centrifuge system, the operator can simply use a shop vac to clear out any debris within the centrifuge cage.
The cartridges (or pods) which hold the cones, along with other tools and accessories, are all dishwasher safe making cleaning a breeze. Every business owner knows that time is costly, and with more time allocated to clean up it means less time allocated to production.
8. The Upside Down Test

All thanks to the ability to control the density of every preroll, the preroll centrifuge system offers a quality assurance test that no other preroll machine can match: the upside down test, or flip test.
This test is performed by taking a preroll and turning it upside down to see if any of its contents falls out. A perfectly packed preroll will have little to no flower falling out, therefore creating less mess in the work area as well as offering the consumer a much higher quality burn.
9. Minimize Touchpoints
Every touchpoint is a potential to damage the finished product. A touchpoint refers to each time the operator must physically touch the preroll during the entire production process. When using the preroll centrifuge system, the operators truly only need to physically handle the prerolls twice: once when dropping the cones into the pods, and a second time during the closing process. Limited touchpoints means that there is less of a chance that you'll damage the preroll cone during production.
10. Quality Consistency
Sometimes the secret sauce isn't in the machine itself, but in the process. Every preroll machine has its own Standard Operating Procedure, which is the process of operating the machine itself combined with all other production steps required prior to, during, or after using the machine.
The preroll centrifuge uses a "cookie-cutter" weight measuring system that was designed to improve the efficiency and consistency of the production process as a whole. It works by creating a measuring template for each strain based on your desired preroll weight (ie. 0.35g, 0.5g, or 1g). Like a cookie cutter, once the template is created it can be easily reused over and over.
