Ziel Patents: Microbial Control Without the Terpene Loss
Mold and yeast looking for the same conditions as cannabis does. The room built to grow good flower is a workable room for growing the organism that fails the test, and it catches careful operators alongside careless ones.
When a batch comes back over the limit, the options are short and most of them charge a fee. Chemical treatments oxidize. Ionizing methods interact at the molecular level and flatten the enzymatic properties that carry a strain's aroma. Extraction turns flower into concentrate at a fraction of the revenue.
Częstotliwość radiowa technology broke that pattern, and in December 2019 the United States Patent and Trademark Office issued Ziel patent 10,517,308, Processing of Cannabis Using Radio Frequency. It was the first patent granted for cannabis microbial reduction by radio frequency.
What the Patent Covers
Most people hear the word patent and picture hardware. US 10,517,308 covers a method: applying radio frequency energy to cannabis to reduce microbial load.
Canada issued its counterpart four months later, patent 2,982,577, under a wider title, Processing of Agricultural Products Using Radio Frequency. The wider title matches the history. Ziel commercialized the technology out of UC Davis in 2008 and spent its first years in tree nuts before moving into seeds, dates and prunes. Cannabis arrived roughly a decade ago, when a large Colorado operator came looking for an answer to newly announced state testing rules. The first unit built for that job is still running.
To comply with 35 U.S.C. § 287(a), Ziel active patent numbers, jurisdictions, and issue dates are fully detailed on the Ziel virtual patent marking page, establishing public legal notice for our entire portfolio.
How Radio Frequency Reaches the Center of the Bud
Radio frequency occupies the part of the electromagnetic spectrum running from 3 kHz to 300 MHz. Ziel equipment works at 27.12 MHz.
Inside that field, the ions and polar molecules in the flower rotate and oscillate to match the frequency, roughly 27 million times per second. That motion converts electromagnetic energy into thermal energy across the whole mass of the product at once, which is why the effect is called volumetric heating. Conventional heat starts at the surface and works inward. Radio frequency starts everywhere.
The depth of penetration is important for flower. Mold begins inside dense colas, where moisture has no route out, and progresses outward toward the surface. By the time it shows on the outside of the nug, the damage runs through the bud. A treatment that only touches the exterior never reaches the colony.
Radio frequency wavelengths run more than ten times longer than microwave wavelengths, which is what gives them the depth to work through a dense product bed, and the exposure is more precise and more uniform than a microwave field delivers.
The other half of the mechanism is what it leaves out. Radio frequency is non-ionizing and thermal. It does not alter the product at the molecular level, the way X-ray, e-beam and gamma do. No chemicals, no oxidizing agent, no residue.
