| 摘要 |
The present invention provides systems and methods that expose high concentrations of a pathogen eliminating gas, such as ozone (O3) gas, to an agricultural commodity. A covered gas chamber, having an entrance location, an exit location, and a conveyor system therebetween, is used to receive an agricultural commodity and to expose the commodity to high concentrations of the ozone gas within the chamber. The gas is supplied to the chamber by one or more ozone generators that are coupled to one or more inlet ports of the chamber. The ozone concentration within the chamber is measured and selectively controlled. The entrance and exit locations include brushes that provide an ozone barrier at each location. The agricultural commodity is received by the conveyor system, enters the chamber, is exposed to the high concentrations of ozone gas, and exits the chamber. The exposed commodity is then delivered to a storage bay, where ozone off gas from the ozone barrier of the gas chamber is delivered.
