History of the can

The very first canned food was discovered during the excavation of the tomb of Pharaoh Tutankhamun in Egypt. It was fried and embalmed with olive oil ducks in bowls made of clay. The most interesting thing is that after lying for so many years in the depths of the earth, they were fit for food.

French culinary expert Nicola Francois Upper spent 10 years proving the fact that hermetically packaged and thermally processed products can be stored for a long time. His invention was put on stream for the belligerent French army. And in 1809 he was awarded the title of "Benefactor of mankind" and a prize. Later, he opened his own business - a store called "Different Bottles in Bottles and Boxes."There was a canning factory in the shop.

Scientific confirmation of Apper's ideas came only after 60 years. Peter Ducane brought the idea to his mind and patented the tin cans familiar to all of us. Of course, they were very different from modern ones. They were made by hand and had a very uncomfortable lid. To open it, you had to use a hammer and chisel.

Since 1819, canned food began to produce America. It is here that the canned food has acquired the kind that is familiar to us today, and in 1860, again, in America, invented a can opener. In Russia canned food has been produced since 1870.

As we can see, for several centuries there were several materials from which cans were made. Let's see now what we are dealing with today.

Manufacturing of cans - all wisdom

From what metal do cans make? Cannery cans:

• made of thin, tin-plated steel;
• is sometimes made of aluminum or other metals.

Why such materials?

• They can be recycled again without losing quality and strength.
• The main difference from other ware for food storage - there is no possibility to backsealize the jar, because at the opening of the jar the metal is cut.

How does the capacitor work?

• The can consists of a casing, a bottom and a lid.
• To ensure that the can is sealed, the longitudinal seam is automatically sealed with tin solder.

Important! When sealing cans, one should not allow alloy particles to get inside the case, since a small amount of lead is included in the composition of the solder.

Alloy is applied only to the outer surface of the can body. In the sealed case, bend the edge to attach the bottom and cover. The bottom and the lid, as a rule, are the same. They are made from sheet or roll of sheet metal with the formation of rings on the surface, which are called hardness rings.

When the finished canister gets into sterilization, pressure rises in it, and the stiffening rings play the role of springs. They allow the bank to increase in volume without damage. After the bank has cooled down, the lid and bottom assume a normal position.

Important! Currently, there are many canned foods, especially fish, which are produced in whole-tamped jars. They do not need to be sealed, you just need to roll the top cover. Usually, low banks are manufactured in this way. Sometimes tin cans are supplied with special keys or tongues for easy opening.
