Canned food is a convenient and popular way to store food for a longer period of time. But how is canned food sealed?
In order to ensure that the food within the can stays fresh and safe, the can must be properly sealed. This is done with a process known as “double-seaming”. The double-seaming process involves two steps: first, the top of the can is folded into a “U” shape, then the sides are folded down onto it. This creates a sealed edge along the entire circumference of the can.
The double-seam is then inspected to make sure it is tight and secure. The seam must be checked for any gaps or tears as any imperfections in the seal could lead to problems with contamination or spoilage of the food inside.
The lid of the can is also inspected to make sure that it fits tightly against the rim of the can and that there are no gaps where air or contaminants could get in.
Once all of these steps have been completed, a vacuum seal is created inside the can by removing all of the air from within it. This helps to prevent bacteria from growing in an oxygen-free environment, which would render the food unsafe for consumption. Once this vacuum seal has been created, a metal lid is added to complete the sealing process and protect against any outside contamination.
Conclusion:
Canned food is sealed using a process known as double-seaming, which involves folding and sealing edges along the circumference of a can. The double-seam must be inspected for any imperfections before creating a vacuum seal inside by removing all air from within it. Finally, a metal lid is added to complete this sealing process and keep out any outside contaminants.
