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.

Systems and methods for producing protein powder are disclosed. In various embodiments, protein powder is prepared by a process comprising sanitizing raw material from aquatic animals mixture with ozone, combining the raw material with a solvent to create a mixture, baking the combined mixture for a first time period, separating, with a filter, liquid from the combined mixture that was baked for the first time period, baking the combined mixture without the separated liquid for a second time period, separating, with a filter, liquid from the combined mixture that was baked for the second time period, curing the combined mixture, and processing the cured mixture to produce protein powder.

A refrigerator appliance and methods of operation are provided herein. The refrigerator appliance may include a cabinet, a storage bin, a lid, an ozone passage, an air conduit, an air handler, and an ozone filter. The storage bin may include a plurality of walls defining a storage volume. The lid may be positioned on the storage bin to selectively cover the storage volume in a closed position. The ozone passage may be defined through at least one of the plurality of walls in fluid communication with the storage volume. The air conduit may be disposed in selective fluid communication with the ozone passage. The air handler may be disposed in fluid communication with the air conduit to direct ozone through the ozone passage. The ozone filter may be disposed in fluid communication with the air conduit to filter ozone passing from the storage volume through the air conduit.

A mobile system is described that that produces and applies an ozonated liquid to clean and sanitize a variety of articles and surfaces. The mobile system includes an ozonated liquid dispensing unit that forms the ozonated liquid from water and ozone gas.

A pass-through system and method for treating and/or pre-cooling perishable products uses a conveyor system with a treatment chamber that is configured to be contained (or closed) to provide a sealed environment and enhanced with forced air flow to recirculate air and/or functional substances including, e.g., sanitizers, as well as ripening management and conditioning agents, across the surface of perishable products. The enhanced forced air is an integral part of the system for efficient treatment and can also be cooled to accomplish rapid cooling.
