Equilibrio higroscópico das sementes de café, fumo e várias hortalicas
This paper deals with the determination of the hygroscopic equilibrium of coffee, tobacco, and vegetable seeds corresponding to relative humidities of their environment varying from 10 percent to 90 percent. Judging by the relatively low dry weights of all the samples held at 90 percent relative humidity, there seems to be no doubt that the high moisture content obtained for these samples were partly due to a decrese in seed dry matter. The rate of change in moisture with change in humidity differed greatly among the various kinds of seeds. Coffee and garden beans gained 0.18 percent in moisture with increase of 1 percent in humidity, while lettuce and tobacco gained half that amount
