Case Study: How the GPC Preroll Centrifuge Really Performs

We recently spent time with a producer who has been running the KungTech GPC preroll centrifuge machine for over seven years. With just one unit, their team is consistently making an average of 40,000 prerolls per day. Here’s what we found when we dug into how this system performs in real-world production.

Reliability and Durability Tests

The GPC stands out for its build quality. After years of daily use, the only service this producer needed was routine maintenance. That’s not something you can say about many other preroll packing systems. The secret is its simplicity.

The GPC only has a handful of moving parts: the motorized centerpiece that spins to pack the cones, the arms that hold and lift the pods, and the lid that seals the system.

Fewer parts mean fewer breakdowns, less wear and tear, and easy upkeep. By contrast, preroll machines that rely on shaking or vibration tend to wear out faster and require more frequent repairs.

Efficiency and Scalability Findings

One of the biggest advantages of the GPC is how much it can produce in a single run. The system can pack up to 396 cones per spin cycle, which usually takes around 60 seconds. The exact time depends on the flower’s density and moisture levels, but even with that variation, it’s fast. In our own tests, we found that a skilled operator could finish between 8,000 and 10,000 prerolls in one day using just a single machine.

The producer we visited runs multiple operators alongside their GPC, which allows them to scale production up to 40,000 prerolls daily. For companies planning high volumes, it’s easy to see how this system pays for itself, sometimes in as little as the first month.

Preroll Packing Quality and Consistency Results

We always say that the biggest selling point of the GPC preroll centrifuge machine is the quality of the final product. By using centrifugal force instead of vibration or gravity, operators have precise control over the density of each preroll.

Adjusting the spin speed changes how tightly the flower is packed, which means consistent results no matter what type of flower is used.

This is a major advantage over vibration-based systems, which can’t be adjusted in the same way and often produce inconsistent packs. The GPC’s ability to dial in the right density makes it one of the best preroll machines for achieving uniformity across every run.

Minimizing Downtime

Every hour a production machine sits idle is money lost. Long cleaning times, breakdowns, or unreliable performance can eat into profits quickly. The GPC is built to reduce downtime in every area:

• Less frequent maintenance needs.

• A straightforward cleaning process.

• Durable construction that can withstand years of heavy use.

That means more of your day is spent producing, not waiting for service calls or dealing with stoppages.

What Can the GPC Actually Achieve?

The GPC can handle serious volume. With a capacity of 396 prerolls per cycle, it takes just three minutes for one operator to load, spin, and unload a full batch. On paper, that translates to over 63,000 prerolls in an eight-hour shift if the workflow runs perfectly.

Of course, real-world numbers will vary, but this shows just how powerful the system can be when paired with an efficient team and process. Even at 40,000 prerolls per day, the producer we visited isn’t hitting the machine’s ceiling!

Bottom line… The KungTech GPC preroll centrifuge system delivers on all the key points:

1. Reliability

2. Efficiency

3. Consistent preroll packing quality

Its use of centrifugal force makes it more precise and durable than vibration-based alternatives, while its output capabilities allow small operations to scale into major producers with ease.
