Open the CIPO recordAbstract From the Canadian patent
A grain containment vessel (205) equipped with one or more antennas (210) and a vapor extraction system (240, 245, 250) is disclosed. An electromagnetic heating pattern is established throughout the grain volume elevating the bulk temperature, while the air flow is applied throughout the grain volume. The electromagnetic energy desorbs the water and increases the vapor pressure and the air low carries the heat and water from the containment vessel (205). A controlled amount of electromagnetic energy is introduced into the grain volume to reduce or eliminate fungus infestation and increase insect mortality.

Why it's free to use
- Filed December 13, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
