Vacuum cover is useful to any hostess. Do not believe me - check yourself

Vacuum caps for canning have appeared relatively recently, and so far they have not been able to win the hearts of those women who are accustomed to the standard version with tin lids or plastic ones. And they are, at first glance, much more expensive. To understand whether the worth of a candle is worth it, you need to make some calculations. And they show that if you do not spare money, learn how to use them correctly, and do not lose quality, then in time it will become clear - the vacuum cover is a very economical option.

Do not believe their quality? Check on your own experience

If you take into account that such a kitchen device - reusable in terms of use, without regretting once money for a quality product, you for a long time will forget about buying tin covers. Each cover can survive two hundred closings, and this service life is not less than three years.

You can usually find on sale sets of three, nine or more covers, and a special pump. You can take a minimum set for a sample to assess the benefits for yourself, understand how to manage them and try out in practice what kind of work will result from the "vacuum". That is, vacuum caps with a pump can and should be purchased for starters as a probe.

Operating principle

First, let's focus on the fact that these covers are only used for glass jars. No other containers with a suitable neck (tin, plastic) for this case are not suitable.

Next, you need to make sure the integrity of the bank. You must understand that by creating a vacuum, you thereby create a pressure inside that is lower than that of the environment. Thus, cracks and chips can contribute to the fact that the bank will burst. And we do not want that, right? Therefore, we carefully inspect the bank for defects.

Naturally, you should sterilize the cans and lids before closing. Then tightly press the cover to the neck, and insert the pump no less tightly. Taking the handle in the handles, move the pump rod up and down until it spontaneously starts to return back down. This can be considered the completion of closure. After you practice, the process will take two minutes to complete. If something comes into the pump from the preservation - brine, pieces of jam, etc., you need to wash it with warm water.

It is easy not only to close, but also to open

To open the preservation, for which a vacuum cover was used, no devices are needed. It is enough simply to raise the valve at the place where the pump is fixed, the air will enter the can and the lid will easily open.

It is practical that even opening a jar of cucumbers, for example, you can again close them with the same lid, and, thus, extend their shelf life again.

Vacuum covers - for canning and only?

About reusable use talked. The advantage that the vacuum cap has over the conventional one is also that it is applicable not only for canning. With the help of such a device you can store even food in the refrigerator. As you know, oxygen badly affects the safety of any type of food, whether it is raw or fresh, it's meat or fish, fruits or vegetables. Vacuum caps for cans will save useful substances and slow down the process of spoilage. If you are an adherent only to freeze or store food in food film, it will be difficult to convince you, but it is possible. Some may find it awkward to store cheese, meat or fruit in cans under the lid. The only argument - the vacuum cap allows you to store the products much longer. Do not need to do this all the time, use this way of storing at the time of departure, for example.

For bulk products, spices, coffee or tea, such a lid will also be an excellent solution. Air will not penetrate into containers with such substances, and will not leave them. Thanks to this, all the fragrances spread by the seasonings will be preserved, moisture will not penetrate them, because of what you can not be afraid of problems with mold, food moth , etc.

Even technical substances such as paint, drying oil, glue, can be saved from fast drying. It is only necessary to understand that in case of contamination it is unlikely that the lids will be re-used aesthetically.
