Vancouver-based EnWave Corp. announced that it has received a new method and apparatus patent from the U.S. Patent and Trademark Office.

The patent is for its Radiant Energy Vacuum (REV), an advanced dehydration technology for cannabis that uses power density and vacuum conditions for optimal terpene and cannabinoid retention.

Traditional drying methods, such as room drying and hang drying, exposes the harvested plants to open air which means operators must routinely monitor the drying room’s environmental controls. The drying rooms can also be a risk to for mold to proliferate due to inconsistent humidity and airflow controls.

EnWave’s REV process is designed to dry cannabis in the absence of oxygen, at low and controlled tempratures. The fresh-to-dry processing time can take up less than two hours and plants can be dried before bioburden and microbes can propagate.


EnWave’s vacuum-microwave dehydration technology is protected by a portfolio of 18 various apparatus and process patents.
