Posted by Custom Cones USA on Apr 26th 2024

In the world of pre-roll production, it all starts with the grind.

Properly grinding or milling your cannabis flower is not just another step in your production process — it’s a foundational piece that can make or break the quality of your pre-rolls.

Poorly ground cannabis leads to inconsistent particle size and gaps inside the cone, often resulting in pre-rolls that run or “canoe” due to disrupted airflow. This not only affects the smoking experience but also impacts the potency that customers can expect from your product.

A poor grind also leaves you with chunks and nugs that can wreak havoc on your pre-roll machines. These larger particles make it difficult to produce evenly packed pre-rolled cones and tubes, which can ultimately hurt your bottom line.

So how do you achieve the perfect grind? In this article, we’ll dive into the main variables that impact your grind so you can elevate your pre-roll manufacturing to the next level and beyond. If you’re ready to become a master of the grind, read on!

What to Look for in a Cannabis Grinder

In some ways, buying a grinder for your business is like buying a car. You want a machine with a powerful but efficient motor that will avoid breaking down over time. And much like when you’re buying a car, you want to pay close attention to the RPM and torque of your grinder.

The RPM (Rotations per Minute) and torque of your grinder play a pivotal role in preserving the quality and overall integrity of your flower. High-quality cannabis grinders typically use low-RPM motors that operate at slower speeds than high-RPM machines. Unlike blenders and food processors, low-RPM grinders help preserve delicate trichomes from being damaged.

One of the main benefits of low-RPM motors is that they don’t generate excessive heat. Terpenes, responsible for the aromatic profile of cannabis, are extremely sensitive to high temperatures and evaporate or degrade when exposed to heat. High temperatures can also harm cannabinoids, such as THC and CBD, which can negatively impact the potency and overall quality of your cannabis.

Maintaining a low temperature throughout the grind will help preserve the natural profile of the flower, resulting in pre-rolls with robust and nuanced flavors that reflect the original strain characteristics. This will also help improve the overall consistency and quality of the ground material, which often becomes dry or brittle due to excess heat.

Instead, look for a weed grinder with high torque, as these machines effectively break down dense cannabis buds without applying excessive force or heat. A high torque motor can efficiently break down tougher material that may be left as big chunks in inferior machines. The result is a consistent grind that has minimal stress on the flower.

A low RPM, high torque cannabis grinder will help you achieve your desired grind and preserve the valuable compounds present in cannabis. Not only will this help you optimize your pre-roll production, but it will also help you meet the expectations of even the most discerning customers.

Particle Size in Cannabis Grinding

One of the biggest factors in the overall quality and performance of your pre-rolls is the particle size of cannabis. When it comes to the particle size in your pre-rolls, consistency is key.

The best way to ensure you produce pre-rolls with a uniform size and density is to have a consistent grind. This will also give your customers an optimal smoking experience thanks to the even burn rates that come with a consistent grind.

Particle size also influences the efficiency of cannabinoid and terpene extraction during smoking. Smaller particles provide greater pack density and surface area in pre-rolls, allowing for more effective extraction and enhanced potency when consumed.

So how do you ensure you’ve broken your weed down to the right size so that it’s ready to pack into cones? For one, you’ll want to find a grinder that can break down material to your desired consistency. A large-scale industrial grinder can easily produce large quantities of weed with a consistent particle size that are ready to load into your pre-rolls.

How to Treat Stems in Your Grind

How you handle stems during your weed grinding and sifting is a key factor in delivering top-notch quality and consistency. It’s crucial to carefully remove stems to maintain the integrity of the final product. We recommend starting even before your weed hits the grinder, removing as many of the larger stems as early as possible.

Grinding with stems leaves excess plant matter and cellulose in the final product, leading to a harsh smoking experience. Stems can also impact the flavors of cannabis strains, contributing to bitter and woody notes that overshadow the desired profile of the flower.

Leaving stems on your flower can also put a strain on your equipment. When you put stems in an industrial cannabis grinder, the larger particle sizes can easily get stuck and add downtime to your production. By removing them prior to grinding, you can streamline production and ultimately produce higher-quality products.

We also recommend that you use a sifting machine to remove any stems that might have fallen through the cracks. This crucial but oft-forgotten step will help you remove any large particles and foreign material that might have made it through the grinder. An automatic sifting machine will further ensure even particle size distribution and high-quality pre-rolls throughout production.

However, when using a shredder-style grinder, it becomes almost impossible to even sift out stems, as the shredders obliterate the stems along with the rest of the flower, making them small enough to slip through most sifters. Again, a high-quality grinder or mill is the best solution to make it easier to remove stems prior to loading your cone-filling filling machines to ensure your product is the best it can be.

Continuous or Non-Continuous Grinding: What’s Best for You?

Choosing between continuous and non-continuous grinding methods depends on various factors, including production scale and equipment capabilities.

Continuous weed grinding with an industrial cannabis grinder involves uninterrupted processing of cannabis material, making it ideal for large-scale operations that prioritize high throughput and efficiency. This method minimizes downtime and ensures a steady supply of ground material, which is crucial for meeting the demands of pre-roll production.

Non-continuous grinding, like that done with a shredder-style machine, processes material in batches, offering more control over each batch's characteristics and quality. This approach is suitable for smaller-scale operations or when specific adjustments to the grinding process are necessary between batches.

When deciding between these two types of weed grinding, it’s best to consider the type of equipment you have available and your desired production volume. An automatic weed grinder will utilize continuous grinding to streamline production, while manual or semi-automated setups may opt for batch processing to maintain greater control over the grind.

Another critical aspect of cannabis grinding is throughput, which refers to the rate at which cannabis material is processed during grinding, typically measured in pounds or kilograms per hour.

Higher throughput is essential for achieving production efficiency and increased output. The capacity and capabilities of the grinding equipment significantly influence throughput, with industrial-grade grinders equipped for high throughput capacities being essential for large-scale cannabis processing facilities.

Understanding your throughput requirements is fundamental for scaling operations and selecting suitable equipment to meet production goals effectively.

Aside from adding spare parts to your inventory, there are a few tried and tested tricks you can employ to your weed grinding to enhance efficiency and product quality.

One lesser-known tip is to keep spare grinder blades in a freezer and ready to swap them in when needed. By storing blades in a cold environment, you can prevent the buildup of oils and residues that can affect machine performance and compromise the integrity of your flower.

Another useful tip is to ensure proper maintenance by regularly cleaning your grinder. Cleaning your equipment thoroughly after each use helps prevent residue buildup and ensures consistent performance. Use food-grade cleaning agents and follow manufacturer recommendations for optimal maintenance.

Additionally, consider implementing temperature and humidity control in your grinding environment. Maintaining a cool and dry atmosphere can prevent the cannabis material from becoming sticky and clumping together during the grinding process. This promotes smoother operation and better particle consistency.

Lastly, experiment with different grinding techniques and settings to optimize particle size and product quality. Adjusting grind settings based on strain characteristics and moisture content can result in better flavor profiles and enhanced smoking experiences. Experiment with these strategies to find what works best for your specific production needs and equipment.

How Grinding Affects Metering

The volumetric metering process used in pre-roll manufacturing relies heavily on the consistency and quality of the ground cannabis. Proper grinding ensures that the cannabis material can be accurately dispensed into each pre-roll, contributing to uniform weights and sizes.

With a consistent particle size achieved through grinding, pre-roll machines can precisely meter out the desired amount of cannabis for each product, optimizing efficiency and reducing material waste.

Inaccuracies in grind consistency can lead to variations in metered amounts, resulting in pre-rolls that differ in weight and density. Therefore, a uniform grind achieved through proper grinding techniques is essential for maintaining quality control and meeting product specifications in the metering process.

Additionally, the metering process is affected by how well the ground cannabis flows through the equipment. Inconsistent grinding can result in material clumping or uneven distribution, causing disruptions in the metering mechanism. This can lead to operational inefficiencies and potentially affect the overall output and quality of pre-rolls.

The particle size and quality of the grind directly impacts the precision of the metering process. Using an industrial grinder and following proper procedure will provide you with more reliable metering in your pre-roll manufacturing.

How Your Cannabis Grinder Affects Burn Speed

The burn speed of a joint is significantly influenced by the particle size and consistency of the ground weed.

Coarse grinds provide a slow and consistent burn – ideal for blunts and for consumers who want to savor their smoke experience. Fine grinds are optimal for vaporizers, as they speed up the heat transfer and maximize cannabinoid activation.

A medium grind is a great option for pre-rolls, as it's a versatile grind that provides balanced airflow and burn rate – offering proper airflow and a classic smoking experience for consumers. The slower burn rate also allows for a more gradual release of cannabinoids and terpenes, resulting in a milder experience when smoked.

To optimize the smoke experience of your pre-rolls, it’s best to experiment with different grind sizes and packing techniques. The goal is to ensure an even and consistent pack throughout the joint, allowing for a steady burn rate without excessive heat buildup.

How Your Cannabis Grinder Affects the Harshness of a Joint

The grind size of weed also significantly impacts the harshness of a joint, due to various factors related to combustion and inhalation.

Finely ground weed tends to burn more rapidly and at higher temperatures due to its increased surface area, leading to a hotter and potentially harsher smoke. Additionally, finely ground particles can create more ash and particulate matter, further contributing to a harsh inhalation experience.

Coarsely ground weed burns more slowly and at lower temperatures compared to finely ground flower. This slower combustion rate produces a smoother and less harsh smoke, as larger pieces of cannabis allow for a more gradual release of cannabinoids and terpenes.

Aside from grind size, other factors play a role in determining the harshness of a joint. Properly cured and hydrated cannabis tends to burn more evenly and smoothly, resulting in a less harsh smoke, for example.

The density and evenness of the joint can also influence airflow and combustion. Poorly packed pre-rolls may burn unevenly and contribute to harshness. The quality and freshness of the weed used in the joint are crucial. High-quality, properly stored weed is less likely to produce harsh smoke.

To optimize the smoking experience and minimize harshness, consider experimenting with different grind sizes and rolling techniques. Many smokers prefer a medium grind to achieve a smoother and more enjoyable smoking experience, combined with proper moisture levels and high-quality weed to reduce harshness.

How Your Cannabis Grinder Affects the Volume of Weed in a Cone or Tube

Grinding weed can significantly affect the volume of weed that fills a cone or tube due to how the particles pack together. The grind size plays a crucial role in determining the density and airflow within the cone or tube.

When weed is finely ground, the particles are smaller and more compact, allowing for a higher density of material to be packed into a cone or tube. This results in a cone or tube that appears fuller and contains more cannabis by weight.

However, coarsely ground weed consists of larger particles that do not pack together as tightly. As a result, a cone or tube filled with coarsely ground weed may appear less dense and contain less cannabis by weight compared to one filled with finely ground cannabis.

Finely ground weed allows for a higher density and fuller appearance, whereas coarsely ground weed results in a less compact fill with lower overall volume and weight.

How to Perfect Your Cannabis Grinding

In the world of pre-roll production, the grind is the foundation of quality. Properly grinding weed isn't just another step—it's essential for crafting exceptional pre-rolls that deliver a consistent, enjoyable experience.

A precise grind ensures uniform combustion, smoother inhalation, and consistent packing, which are crucial for customer satisfaction. Without it, pre-rolls can burn unevenly ("canoe"), impacting both the smoking experience and the product's potency.
