HOUBS DRIED Fig. 7.—Effect of sulfur dioxide and steam on the drying time of dehydrated peaches. Effect of Preparation and Pretreatment on the Drying Time.—That steam treatment shortens the time required for dehydration is shown by figures 6 and 7, but no distinct nor consistent effect of sulfuring appears. As shown by figure 8, however, sulfuring shortened the time required for sun-drying. In the experiments which furnished the data for figure 8, it was noted that while the sulfured samples always dried faster than the unsulfured ones the samples in each series sulfured for different lengths of time and containing varying amounts of sulfur
