The next place is the lard department. Here great closed tanks cook the fats, under high steam pressure, and make them into snow-white lard. There are great open caldrons, steam jacketed, where an even and uniform temperature is maintained. Only the pure leaf lard, which is supposed to be the choicest fat of the hog, is cooked in these kettles. In the lard packing room there is much automatic machinery, with which the various sized packages of lard are weighed out. Machines hermetically seal the tins, and men pack them in crates and carefully weigh them over two scales.
The average person does not have even an idea of what the modern curing cellar is like. The brines and curing mixtures are prepared by trained men who do no other work but this. Everything goes exactly according to formula, and the different ingredients are weighed out to the ounce. The guide insisted that a bare ten per cent of all the hams or bacon sides produced in the plant are finally allowed to bear the company’s trade-mark. The men who finally select these goods are the oldest and most trusted employees of the firm. They weigh out a certain amount of this meat for each tierce, or vat, to be packed, and then an exact number of gallons of pickle is put in with the meat so that each pound of meat will have just a certain amount of pickle to cure it. This is said to insure a uniform product so that one trade-marked ham is exactly like another.
Even the length of time which these are left in cure must not vary a day. In the great curing room thousands of vats and tierces are piled, and the usual tierces hold about three hundred pounds of meat, while the vats hold nearly fifteen hundred pounds.
In the dry-salt curing cellars are kept enormous stocks of the cheaper kinds of meat. These, instead of being cured in brine, are rubbed in salt and piled away. These piles are perhaps three or four feet high, and are so neat and true that they appear to have been the work of a master mason. A single one of these dry-salt curing rooms holds over three million pounds.
Sliced bacon, fancy sausage and other specialties are usually packed in a separate room, into attractive cartons for the retail trade.
The standard of cleanliness in the sausage kitchen has to be unusually high. Wherever white tile is not possible, white paint is used in profusion. The shining metal tables and trucks, on which the product is handled, give a new confidence in sausage. The girls and men employed all wear clean white aprons, jackets and caps, and no effort is spared in keeping everything and everybody in the place in an ideal condition.
The meat is run through enormous automatic grinders and choppers, and through mixers that approach a dairy churn in size. After it has been properly mixed and thoroughly taken care of, it is put into automatic machinery, run by air pressure, which stuffs it into the ham sacks and casings, in which we see the sausage in the markets. The cooking is done in great vats and in enormous electric ovens.
When we stop to think of the proportion of our food which is a packing-house product, we can be glad indeed that conditions such as those described above are becoming available more and more every day.
