But everything changes, and the old banks have replaced new ones, the covers of which are twisted. That's why more and more housewives are asking such a question: "How to roll up cans with twisting lids?"

Operating principle

Screw caps are called twist-offs and have been used for a long time for conservation in Western countries. The essence of their principle of work is as follows. On the inside of the cover there is a special polymer coating, which serves as a gasket. Under the influence of high temperature, it expands and tightens the jar tightly. With decreasing temperature, as the cooling cools, the top of the lid is pulled inward, which is followed by a slight click. As a result, the bank creates a vacuum effect. Therefore, before you roll up the cans with twisting lids, you need to cover the lids.

First, you need to sterilize the banks in the same way as usual. At the same time, this can be done with lids. The temperature for the lids should not be more than 60 degrees. Otherwise, it will lead to the destruction of the polymer coating.

The heated lid is placed on the ready-to-roll jar. In this case, it is necessary to make sure that the furrows on the lid exactly coincide with the strips on the can. And more important is the inspection of the can, or rather the neck, before rolling up the cans with twisting lids.

Quality control

In order to check and relieve yourself of unrest about the reliability of the performed conservation, set the closed cans with the neck down. In this position, they must stand for at least 2 days. If during this time there were no streaks and the lid was not swollen, then you can safely hide the jars in the cellar or cellar.
