Dairy Industry (1940s)

ble is lifted up again on the next machine where heavy pasteboard caps are pressed into place these caps are fitted tightly to protect the purity of the milk then a protective outer covering is put on it is made of waxed cardboard and covers the entire top of the bottle this is fastened on securely as an added Safeguard although it comes off easily when you want to open it yes they're pints of delicious chocolate drink here you see them coming from the filler at the rate of about 144 bottles a minute and here is where the wax fiber containers are filled each holds one quart of milk this machine automatically lifts up each cap fills the container seals it and stamps on the date as containers leave the machine each is inspected and placed in a case on a conveyor that takes them to the cold room for delivery to stores early the next morning here's where buttermilk is churned many people like the oldfashioned churned buttermilk better than any other drink this is an imaginary izing unit to homogenize grade a milk the milk is forced under high pressure through tiny holes this process breaks up or explodes the butterfat globules mixing them into every drop of milk the fat being so evenly divided cannot rise to the top of the bottle to form a cream layer therefore there is no cream line in a bottle of homogenized milk this type of milk tastes richer because the cream is evenly distributed throughout the entire bottle of milk before the mizing process vitamin D is added so that each quart is fortified with the sunshine vitamin after dairy products are bottled they're put in a clean case on a conveyor which takes them to the coal room now let's visit the laboratory this is the control laboratory these men and women are highly skilled technicians they make tests every 15 minutes of the day to make sure that all milk and all other Dair products are up to high standards of Purity and richness so you see there is Magic in milk magic of a kind that you never even thought about spectacular Magic [Music] it's just a hat and a derby one at that take a look inside oh there's nothing inside not a thing turn it over reach in there Mr kater and see what you find I don't [Music] know oh it's a chicken watch there again an [Music] egg and another one now that's been a mighty busy chicken Mr catar you can come to our egg Department any time with that [Music] [Applause] chicken hold on young man here comes someone to help you stay right over there we're afraid he'll drop one there's that one and another one and another we must handle these eggs with care whoops there went one be careful of that one whoops there went another one wow scrambled eggs well Mr cater there went another one that's an inexhaustible egg supply oh stack them up carefully there's another one dropping there's plenty of magic in other dairy products too let's see what particular kind we can discover in eggs freshness in eggs is just as important as freshness in milk the dairy company is just as particular about the quality of eggs as it is about the quality of milk chickens are allowed to run on the Open Range until they grow strong and healthy later when they start laying eggs they're placed in individual pans remember how copper feeding helped the cows well proper feeding of chickens helps to control the color of yolk thickness of shell and flavor of the egg a report is kept on each hen's production she gets accurate credit for the size an amount of eggs She lays during the year eggs are gathered from the pen several times a day to make sure that they reach the market in top condition eggs may be of several grades and are sorted at The Farms according to their weight Packers sort them correctly and if they're doubtful about any egg they weigh it on a delicate scale this is called candling because in the old days it was done by candlelight holding the egg against a strong beam of light shows whether it's absolutely fresh and perfect inside the shell no matter how fresh and perfect the country eggs are supposed to be your Dairy company checks everyone before delivery there is no substitute for or butter let's see how it's made here the Butter Churn is being filled now of course butter is a dairy product and you naturally expect to get it where you get your milk butter is made of sweet cream that has been pasteurized and then kept cold until it is put into the churn then the doors are fastened up good and tight and electric motor is turned on and the churn revolves until butter forms then the churn is stopped and the doors are open the butter maker checks the butter for proper consistency almost everybody likes butter slightly salty so the butter maker adds just the right amount of salt afterwards the doors are closed and the churn is run a little longer to mix the salt evenly throughout the butter the butter is then removed from the churn placed in tubs and shipped to City plant let's go along and see what happens there here absolutely clean dust proof air conditioned room a machine cuts the butter into blocks ready for packaging each block weighs exactly a quarter of a pound no human hands ever come into contact with butter this automatic machine wraps it in parchment paper the individual wrapping of each qu pound of butter protects its flavor and helps the housewife in serving and cooking after the quarter pounds are wrapped they are automatically stacked 4 to a pound and a mechanical hand places them in position for sealing into a wax carton to protect freshness and Purity so you see butter comes in fresh from country creamies every day and the dairy plants carefully pack it so that it's always fresh when your dairyman delivers it [Music] now we'll go to a country Cheese plant cottage cheese is made at Country receiving plants and it's a healthful dairy food here pure fresh pasteurized milk is placed in a large stainless steel tank then cheese makers add what is called a starter this ripens the cheese the starter creates a curd formation which is broken up by cutting with stainless steel wire knives this is what cheese makers call digging a ditch they cut a ditch the length of the tank to drain off the whe a liquid that remains after the curd forms after the cheese is Thoroughly drained and the proper amount of Rich cream has been added it is packed into cans and shipped to the bottling plant so come along and we'll see what happens there cheese jars are washed and sterilized in the same careful way as all glass containers used for dairy products after inspection they travel along to the automatic filler here cans of cottage cheese from the country plant are emptied into the stainless steel Hopper of the automatic filler this machine fills jars a good deal like the milk bottling machines here chive cottage cheese is being bottled it pours in just the right amount and then caps the jars automatically cottage cheese goes to the cold room along with milk cream buttermilk chocolate drink butter and eggs to be ready for delivery the next morning everything your Dairy company sells must be kept cold to protect its freshness and flavor that takes ice lots of it pure water is frozen into big 400 lb cakes removed from the freezing unit and sent down a chute to the storage room where it stays until it's needed the large cakes go through an ice crusher and the crushed ice goes to a bin near the loading platform remember milk is almost ice cold when it's bottled and packing it with crushed ice keeps it cold right up to the time it's delivered every day each piece of plant equipment is scrubbed with Cleaning Solutions and rinsed with boiling water every piece of dairy equip equipment has to be taken apart and thoroughly washed and sterilized hot steam is used to sterilize the pasteurizers and all pipes that Supply milk to tanks and bottle [Music] fillers each morning your dair's delivery Fleet lines up alongside the Distributing plants the salesmen have placed their orders the night before and their dairy products are waiting for them on the conveyor large trucks deliver dairy products to stores and other wholesale users Neighborhood Grocery and delicatess stores in every part of the city receive fresh milk and other fresh dairy products for their customers every day other large trucks delivered to the many hospitals throughout the city every
