In the case of evaporated milk (unsweetened, sterilized) all cans coming from the incubating room should be individually shaken by hand. All cans showing no signs of bulging, and the contents of which shake with the characteristic sound and behavior of a liquid, pass inspection. If the ends of the cans are bulging or the contents do not respond to the shaking with the characteristic sound of nor- mal milk, they are rejected, as the evaporated milk in them has either undergone gaseous or curdling fermentation, and is spoiled. LABELING Labeling Machines.—In the early days of the milk condensing industry, the labeling of the cans was done by hand, involving much. Fig. 47.

The efficiency of these machines is such, that they have become a perma- nent fixture in practically every condensery selling canned goods. They are adjustable to various sizes of cans and can be operated by hand, motor or belt power. Principle of Labeling Machines.—The cans are placed into a chute from which they roll into the machine by gravity. They are caught by two endless belts which draw them through the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hunziker, Otto Frederick, b. 1873.
