But everything is changing, and new banks have replaced the old ones, the covers of which are twisted. That is why more and more housewives are asking such a question: "How to roll up cans with twisting lids?"
Screw caps are called twist-offs and have long been used 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 small 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.
Most housewives, looking at their neighbors or girlfriends, decide to buy themselves such covers, and how to roll up banks with twisting lids, do not know. There is nothing complicated here. First, you need to sterilize the banks in the same way as usual. At the same time, this can be done with covers. 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.
In order to check and relieve yourself of worries about the reliability of the performed conservation, set the closed cans with the neck down. In this position they should stay at least 2 days. If during this time there are no streaks and the lid is not swollen, then you can safely hide the jars in the cellar or cellar.
