Dry cannabis better, faster: Increasing speed to market and reducing drying bottlenecks

Are you leaving terpenes on the table? Currently, the vast majority of commercial cannabis producers rely on slower, less efficient traditional drying practices that can result in lower-quality end products and increase the likelihood of mold and bacteria contamination during the drying process.

So, what is the best way to dry cannabis at commercial scale?

REV™ (Radiant Energy Vacuum) dehydration technology takes your standard 7-14 days of drying time down to just 2 hours, while also enhancing your finished product quality and reducing risk of contamination during the drying cycle.



Methods of cannabis drying have evolved over time, which can likely be attributed to the taboos associated with cannabis commercialization in several countries. Two widely regarded traditional approaches to drying cannabis include rack drying and hang drying, which both require 7-14 days in large dedicated drying rooms. Additionally, there is no way to forecast the endpoint of overall time for the drying cycle, so growers typically deem the bud dry based on the texture. However, these methods are problematic as they are time inefficient and facilitate the growth of mold. 

Needless to say, there are challenges with traditional drying methods, including long drying periods, loss of terpenes and cannabinoids leading to lower quality end products, and risk of mold growth, to name a few.  

Freeze drying is another commonly used modern method of drying cannabis. Freeze drying cannabis takes an average of 10-15 hours, which is faster than traditional methods but consumes considerably more energy.

How to Dry Cannabis Faster

REV drying is a relatively new process that reduces bottlenecks and decreases drying time compared to traditional drying methods such as hang drying and rack drying. High-frequency microwaves create a vapor pressure within the cannabis flower structure, forcing moisture outward.

Customizable Benefits of REV Drying

REV has faster operational speed, uses energy more efficiently, has lower operating costs, and produces higher quality cannabis compared to the above mentioned drying methods. A research article published in 2021 states that REV technology “combines the advantages of the rapid volumetric heating by microwaves and the low-temperature evaporation of moisture with faster moisture removal by vacuum” (Challa et al., 2021). Moreover, microwave vacuum drying can uniformly dry cannabis to precise specifications, allowing cultivators to customize their finished product for premium smokable flower or oil or edible infusion.

Increase Your Drying Speed

EnWave’s Terpene Max protocol on a 120kW machine can transform 140 lbs. of wet cannabis into 33 lbs. of dried, ready-to-cure product in just 60-90 minutes. Our Rapid Extract or Bioburden Redux protocol on a 120kW machine can transform 230 lbs. of wet cannabis into 50 lbs. of dried, ready-to-cure product in just 60 minutes. The increased speed helps bring products to market faster, creating more profit potential. EnWave Tray Machine

Decrease Your Drying Space

A 120kW REV drying machine occupies less than 2,000 sq feet of valuable real estate in your cultivation facility, compared to almost 9,000 sq feet to produce the same throughput required for hang drying cannabis. This allows large cultivators to optimize their facility use and scale up to additional REV drying machines as their production capacity and product offering evolves.

Superior Finished Product Quality

REV drying improves cannabis quality as well as speed to market. The REV drying process preserves up to 20% more terpenes and 25% more cannabinoids than hang drying based on independent 3rd party laboratory results. Terpenes are an important aspect of evaluating cannabis quality as they impact the overall potency, in addition to the enhanced smell and taste of certain strains. Cannabinoids interact with receptors in the central nervous system, which regulate cell communication.  

The process of REV is a closed-loop extraction system, which protects against contamination. Furthermore, REV drying using Rapid Extract or Bioburden Redux protocol achieves more than a 3-log reduction of crop damaging microbes compared to traditional drying. This means more of your high quality, premium dried cannabis actually makes it to market with less risk of crop loss in the final post-harvest stage.


Reducing inefficiencies and bottlenecks is critical in strengthening commercial cannabis operations. Your organization’s people, processes, and technologies are at the forefront of your operational efficiency. REV technology is an innovative, one-of-a-kind solution that redefines cannabis product potential and drying capabilities while lowering costs, simplifying operations, reducing risk improving quality, and ensuring product and process consistency.  

Speed and quality are critical features in cannabis production. Therefore, having a system that diminishes work-in-progress build-up while preserving potency is key. EnWave’s cutting-edge REV vacuum microwave drying targets inefficiencies, obliterates wait times, and produces exceptional products.
