TREATING STORED CROPS UTILIZING RECYCLED AIR

摘要

A stored crop treatment system includes a crop storage chamber and a gas stream circulation pathway which includes a re-circulation loop comprising the crop storage chamber. A feed mechanism feeds stored crop treatment material into a stream of gas moving through the re-circulation loop wherein the stream of gas comes from the crop storage chamber. A heat exchanger heats the stream of gas to thermally generate an aerosol of the stored crop treatment material. A blower moves the aerosol along the re-circulation loop to apply the aerosol to stored crops within the storage chamber. The circulation pathway includes a cooling gas loop comprising the crop storage chamber and a section of the re-circulation loop. Cooling gas from the crop storage chamber moves along the cooling gas loop into the section of the re-circulation loop to cool the heated stream of gas and aerosol prior to entering the crop storage chamber.
