The process includes a treatment step during which a liquid containing a biocidal and/or plant-protection product or a mixture of biocidal and/or plant-protection products is evaporated and injected into the internal atmosphere of premises, the liquid being evaporates at a temperature of less than 50° C., the product vapour concentration in the internal atmosphere of the premises being kept at greater than 10% of a saturation concentration of the vapour of said product in said atmosphere at said temperature for a saturation duration of greater than 12 hours.

The disclosure discloses a method for killing A. Flavus spores by infrared radiation in coordination with essential oil fumigation, and belongs to the technical field of sterilization. The method is to treat A. Flavus spores by medium and short wave infrared radiation in combination with essential oil fumigation. The disclosure provides a method for killing A. Flavus spores by medium and short wave infrared radiation in coordination with essential oil fumigation. On the one hand, air residual heat and energy of medium and short wave infrared radiation are fully used to make a material heated up rapidly, and on the other hand, essential oil on the surface of the material penetrates the cell membrane of A. Flavus spores, and further damages protein on the membrane and internal organelles in combination with the heat effect. The process is easy in operation, low in energy consumption, pollution-free and high in sterilization efficiency, and can be used for purifying bulk grains.

Methods for reducing contaminants in cocoa beans are disclosed. The method includes placing the cocoa beans in contact with an effective amount of ozone, thus reducing a level of contaminants in the cocoa beans. The contaminant may be a smoky odor, a different off odor, microbes, or combinations of any thereof. Systems for reducing contaminants in cocoa beans are also disclosed.

Systems and methods for treating grain stored in a grain pile with ozone are effective for treating grain for toxins, insects, mold, and/or odor. A method according to embodiments of the invention involves monitoring at least one of temperature and odor at a plurality of aeration outlet locations spaced around the grain pile. When an abnormal temperature variance or odor is detected at one or more of the aeration outlet locations, a determination is made as to a problem location within the grain pile where a treatment of ozone should be applied, and a further determination is made as to how best to apply ozone to the problem location. Ozone is then applied to the problem location within the grain pile to minimize nascent problems in the grain pile. The ozone treatment may reduce molds and toxins.

Methods and systems for treatment of grain in a storage container using ozone may be used for treating grain for toxins, insects, mold, and/or odor. Downdraft methods for applying high concentrations of ozone to grain in a storage container treat grain without generating ozone-related objectionable odors or with generation of only minimal ozone-related objectionable odors. A method for downdraft ozone treatment of grain with minimal generation of ozone-related objectionable odors involves providing a negative air pressure at a bottom of a volume of grain in a storage container. A high ozone concentration is generated in air above an upper surface of the volume of grain. The ozone is drawn down into the volume of grain using the negative air pressure for a treatment time sufficient to effectively treat the grain without causing significant ozone-related commercially-objectionable foreign odors in the grain.
