资源简介:
Photograph of a dryer for Calcium Citrate at the Exchange Products Co., ca.1930. What appears to be the large, cylindrical dryer lies on metal supports on the left with gauges protruding from its front. A rounded, tile wall stands behind a thick support beam on the right while a pile of lightly-colored sacks sits in the background at center. Other machines can be seen on an upper platform that extends over the dryer.
