Excerpt from Improved Sulfur Dioxide Fumigation of Grapes Loaded in Railway Refrigerator Cars Different combinations of fans in the cars were tested with various load patterns and shipping containers. Prepackaged grapes in master cartons cannot be fumigated satisfactorily after loading in the cars. In standard ice bunker cars, a portable fan was placed in the center of the car between the braces that hold the divided load in position. This fan blew air upward during fumigation and gave uniform gas distribution through loads of grapes packed in 28-pound lug boxes. Bunker fans also mixed and distributed the fumigant satisfactorily when the gas was applied slowly. High ice meltage absorbed a significant amount of sulfur dioxide and removed it from the car as the water drained out. An additional amount of sulfur dioxide had to be provided to compensate for this loss. The best results in mechanical refrigerator cars were obtained when the gas was released in the space above the load at the' end of the car opposite the blower.
