Title:  Montage of tablet production machinery.
Date:  ca. 1925-1940
Dimensions:  8.5x11 inches
Note:  Inscription: [See individual photos for captions.] ; Recto: Tablet Room, Shelf Dryer, (Right) Evaporator, (Below) Tablet Tanks; Verso: [...] sugar was omitted, as well as the use of the powdered crude herbs, and from this time on all tablets have been made from extracts. This change soon required the installation of an almost entirely new line of machinery and equipment. The original steps of macerating and precolating are handled similarly to those used in the liquid Compund, but the percolate is then run into a large vacuum still or evaporating kettle in which more than 900 gallons of liquid are boiled down to about 225 to 250 pounds of semi-solid extract, containing only a few percent of moisture. This extract is then put in pans and dried in the shelf drier to final dryness. It is then ground, sifted, put through the slugger, and then pressed into tablets by modern, high-speed tablet punches. These tablets are then coated and polished before being packed. In 1938 When iron was added to the tablet formula, a similar process was used in handling the herbs and extracts, and the iron in the form of exsiccated or dried ferrous sulphate was mixed with these just before slugging. The process for handling this was developed for us by Merck & Company and Gustavus J. Esselen, Inc., and tests on each lot being put through by Esselen show an extremely high stability and evenness in iron content.; Caption: Tablet Room Negative Description - 1 Negative 4 Pictures 1st.
