Despite the fact that preservation can be purchased now in almost any supermarket, our skilled housewives still find the time and effort to close their favorite salads and vegetables with their own hands according to their own or grandmother's recipe. Indeed, such preparations are much tastier than the store ones, and they are prepared with love. However, no matter what method and recipe preservation is prepared, tightness of closure is always in the first place. It is thanks to this characteristic that the bank retains all the properties of the products and prevents the workpiece from deteriorating. And what determines the tightness of the container? Right, from the cover. And to be sure of the duration of storage of the workpiece, you must correctly use and choose a seaming machine, which we will talk about today.
What is the difference between a seaming machine and a classic?
The function of these devices always remains unchanged, and outwardly the differences are minimal. Unless the seaming machine-automatic is different in the number of handles (there are 2 of them, no more), simplicity and ease of operation. The efforts that need to be spent on twisting the lid are much less than those spent using a power tool.
Principle of operation
In order to prepare preservation in high quality, it is enough just to make one movement of the handles. The whole process of twisting the lid is carried out in a matter of seconds, which is the main advantage of this machine. Design features of this mechanism are the principle of action. The seaming machine is a system of levers interacting with a rigid spring. By the way, in order to clog the jar, it is enough to make an effort of 2800 grams. It is necessary to spend much more effort, and sometimes nerves, on the use of a mechanical one (after all, the lid is not always screwed on the first try).
How to use a seaming machine?
Before you begin to twist, you need to carefully sterilize the container and, of course, the lid itself. To achieve the desired result, simply hold them over a boiling pot with water for several minutes. Steam is the best tool that most effectively removes not only accumulated deposits and dust in the bank, but also all kinds of bacteria. After both parts are sterilized, it is necessary to put the lid on the container and install the sealing key on top. Next, you need to simultaneously press both handles. The spring, which is located in the case of the seaming machine, squeezes the edges of the lid around the neck, thereby eliminating the possibility of air getting inside. Thanks to the special design of the rigid profiled sections, the forces are evenly distributed over the surface of the rolled element.
It should be noted that the seaming machine-automatic machine (Mashenka as well) excludes the risk of various deformations on the glass surface, which appear in the form of chips and cracks, as happens when twisting with a mechanical key. This is facilitated by a special stopper, which serves as a kind of limiter that does not allow the tin lid to twitch more than is necessary for a tight tightening of preservation. By the way, such devices cost about 250-500 rubles.
