Canned food has become an essential part of our lives. It’s convenient, readily available, and can be stored for a long time.
Canned food is a safe and healthy way to enjoy food. But have you ever wondered how the cans themselves are made?
The Canning Process
Canning is a process that involves sealing food in an airtight container to preserve it and prevent contamination. The containers used for this process are usually metal cans. Cans are made of steel or aluminum, which are both durable and lightweight materials that can withstand high temperatures and pressure during the canning process.
Making the Can
The first step in making a canned food can is to create the body of the can using sheets of metal. The sheets are cut into circles of a specific size and then formed into cylinders using a press machine. Once the cylinders have been formed, they are joined together with metal seams to form the body of the can.
Applying Protective Coating
After the body has been formed, it is then coated with an enamel or epoxy coating to protect it from corrosion and extend its shelf life. The coating also helps give the cans their glossy finish that makes them so attractive on store shelves.
Adding Lids and Seals
The next step in making canned food cans is adding lids and seals to ensure that the cans remain airtight when they’re filled with food products. The lids are usually made from aluminum or tin-plated steel, while seals are typically made from rubber or plastic gaskets that prevent air from entering or leaving the container once it’s sealed shut.
Filling Cans with Food Products
Once all of these components have been added, it’s time to fill the cans with food products. This process involves placing predetermined amounts of food products into each can before they’re sealed shut with lids and seals. Once sealed, they’re then heated to sterilize them before they’re ready for sale on store shelves around the world.
Making canned foods requires a lot of steps but in essence all boils down to cutting metal sheets into circles, forming them into cylinders using press machines, coating them with protective coatings, adding lids and seals, and finally filling them up with predetermined amounts of food products before sealing them shut and heating them up for sterilization purposes before sale on store shelves around the world.
