Drying cannabis has long been an art form rather than a science. Traditional methods often rely on subjective tests like touch and stem snapping. This has left plenty of room for human error. The traditional method also leads to the risk of over-drying cannabis, which degrades the plant’s quality. Similarly, chances of under-drying cannot be overlooked, as this can lead to mold and spoilage. Achieving perfection and consistency in drying cannabis has been a perennial challenge for the industry, as fluctuating environmental conditions and a lack of precise control compromise the quality of the final product.
Bringing Food Science to Cannabis
In a new move to redefine cannabis drying, techniques honed in the cheese and meat industries are now being adapted for processing cannabis. This method is primarily based on vapor pressure control. Originating from the aged meats and fine cheeses of old-world caves, this method carefully manages the balance between dry bulb temperature and dew point. By replicating these natural aging conditions, vapor pressure control allows for precise regulation of moisture loss, directly impacting product quality.
Controlled vapor pressure introduces a new era of precision in cannabis drying, mirroring the sophistication found in food science. Unlike conventional methods that merely control room temperature and humidity, vapor pressure control adapts the drying environment to the specific needs of cannabis. This shift from makeshift drying rooms to scientifically controlled spaces marks a significant advancement in the industry.
David Sandelman, co-founder of Cannatrol, recognized the potential for this food science application to revolutionize cannabis drying. “When people were saying we’re producing some of the finest flowers with our equipment, we started digging into the science. We realized that with conventional drying, about 25 to 35 percent of trichome heads are ruptured, but with our system, only 1 to 2 percent are damaged,” says Sandelman. This meticulous approach retains more of the plant’s delicate structures, ensuring potency while preserving its flavor.
The Benefits of Vapor Pressure Control
The advantages of controlled vapor pressure drying are amazing. Not only does this method enhance consistency, but it also preserves up to 16% more terpenes. Terpenes contribute to the aroma and flavor of cannabis, playing a critical role in the consumer experience. With more terpenes preserved, the resulting product offers a smoother, richer taste, a crucial factor for standing out in an increasingly competitive market.
Moreover, vapor pressure control addresses a major pain point for pre-roll manufacturers. Traditionally, pre-rolls can be harsh and inconsistent, largely due to uneven drying and curing processes. Cannatrol’s Storage Series, designed specifically for the pre-roll market, safeguards the integrity of the raw flower from manufacturing through to the point of sale, promising a consistently enjoyable experience for the end user.
The Future of Controlled Vapor Pressure in Cultivation
As cannabis research is advancing, the potential applications of controlled vapor pressure techniques are also extending into the cultivation phase itself. Imagine indoor growing environments where precise moisture control accelerates growth rates and enhances plant health. Such advancements could transform cultivation practices, improving quality and yield across the board.
Many cannabis drying facilities across the U.S. are utilizing this method to deliver premium-quality cannabis to the market. This progressive scientific approach is disrupting traditional norms and setting new standards in the industry. By embracing this new method, cannabis processing facilities are not just refining drying techniques but are poised to elevate the entire cultivation cycle, changing the way cannabis is processed after harvesting.
A New Standard for Cannabis Quality
As the cannabis industry matures, innovations like vapor pressure control are setting new benchmarks for quality and consistency. Borrowing from the proven practices of food science, this approach promises not only a better product but a more efficient and reliable process. As more and more cannabis processing facilities adopt this new technique, the future of cannabis drying—and perhaps cultivation—is looking more promising.
