In this location, the Research and Development (R&D) department also managed the Quality Assurance (QA) program. In line with QA requirements, they tested product samples by developing cultures (in Petri dishes). The process of developing cultures requires a constant temperature of about 30 C for several days. There were eight ovens in the laboratory for providing this controlled environment.
The ovens had a large cavity, about 3' wide, 3' deep and 30" high. A set of electrical heating elements along the side walls provided heat. A bimetallic thermostat turned the heating elements off when the temperature exceeded set limits. A small fan 8" in diameter was mounted at the center of the ceiling of the oven. It rotated very slowly, gently wafting the warm air from the sides down the center of the oven. The intention was to produce a toroidal flow path to help distribute the temperature uniformly in the oven (see Figures 43.1 and 43.2).
Petri dishes, about 4" in diameter, containing the culture samples were placed on wire trays. The latter allowed free flow of air. These...
