The true mistress in the summer-autumn period is engaged in harvesting for the winter. Home canning is always held in high esteem. Undoubtedly, what the preservation will be as a result depends on many components: the recipe, the quality of the products, as well as the experience and skill of the hostess. The main requirement for clogged banks is tightness. If a small gap remains under the lid, air and germs can enter the jar. Therefore, every housewife should know how to roll up a can with a seaming machine . Not the last place in canning is reserved for the seaming device. In order for closed banks not to explode, the device must be of high quality.
Types of Twist Wrenches
The following types of seaming machines are available:
1. Automatic. The machine is quite easy to use and does not require special skills. We put a lid on it, then, pressing it, we turn the levers in a circle a couple of times. The cap is pressed against the neck of the can by the springs located in the inner part of the key. The whole procedure of spinning with an automatic key will take no more than half a minute.
2. Semi-automatic. Such a key is always in greatest demand, because it is convenient in operation. To roll up the tin lid, the key handle is turned a couple of times in one direction, while pressing the lid tightly. Working with such a key is one joy.
3. The key - the "snail" takes a little more time during the spin as compared to the previous ones. On such a machine there are grooves with which the key probe moves, moving toward the center axis.
4. Two-roller seaming key. When clogging the cans in this way, the box with the clamping device is placed on the table, and then the can is brought to it, fixed, turning the screw three times. Then the cartridge is placed on top of the jar. Frequent continuous movements are made, then the lid edge fits snugly to the neck of the can in a circle.
Preparatory process
In order for the billets to be preserved until the new crop, jars must be prepared immediately before rolling. Perhaps not everyone knows how to roll up the jar correctly, but it is very simple to do so.
The simplest method of preparation is this: thoroughly washed jar is poured with boiling water, then put the neck down on the kettle in which water boils, and sterilized for about 15 minutes.
There is another way, for someone it will seem even easier. Each jar is poured with boiling water twice, after which hot water is poured into the jar for a couple of minutes, and at this time the lids are boiled.
You can sterilize the banks in the oven. Wash the jars cleanly, place them in the oven while it is cold, and then heat the oven to 150 Β° C and leave for 10-15 minutes.
Nowadays, many people sterilize cans before rolling in the microwave.
When it comes to seaming, we put the lid on the neck of the jar, then put the machine on it and make sure that the lid is pressed tightly to the jar to the maximum. The instructions for the key always indicate how to roll up the can with a seaming machine. After the process is over, we check whether the can is hermetically rolled up, for this we turn it with the lid down.
Alternative to rolling key
Everyone knows how to roll up cans for the winter, but not everyone knows that instead of a seaming key, you can use a vacuum pump with special covers. At the same time, we only close the jar, pump out the air - and you are ensured tightness.
By the way, the covers are also different. There are a few little secrets on how to choose them. For example, yellow tin lids coated with varnish are of better quality, but white unvarnished tin can be oxidized, so they are not suitable for spins with marinades or preservation of products from sour berries, but are great for rolling sweet jam. Lids made of polyethylene can melt at high temperatures, therefore, they can clog jars that do not need to be sterilized. Peculiar covers made of fragile material - glass require special clamps, however, if used correctly, they will last more than one year.
Semi-automatic machine for spins
So that your cans are closed firmly and reliably, the spins are kept all winter, you need a rolling machine for cans semiautomatic devices. When using it, you should adhere to some rules:
- the jars filled with hot products are covered with freshly sterilized lids;
- install on the cover a semiautomatic device;
- turn the handle of the key in the clock;
- do several circles (7-8);
- semiautomatic stop means that all twisting circles have been completed;
- untwist the handle of the machine and remove the sealing device;
- check the tightness of the seaming.
That's all the nuances of how to use the sewing machine semi-automatic correctly. As you can see, this is not at all difficult.
If you observed all the rules of how to roll up the can with a seaming machine, but it so happened that the seaming device accidentally flew off the lid, then unwind it, returning it to its original position. After rolling up, start the spinning process again. By the way, if you use semi-automatic machines for canning at home, you can be sure that your stocks for the winter will be safe and sound.
Tightness of cans
Another little secret when using a key to spin - inspection of the banks. When it is closed qualitatively, the lid rim has a smooth surface without any dents or bulges. How well the lid is sealed can be checked in this way: we take the curled jar with one hand at its bottom (carefully so as not to burn your hands!), And with the other we try to rotate the lid itself. If it does not move, then everything is done just fine.
Spin Storage
After such a peculiar check, we turn the cans upside down, wrapping them first in a paper newspaper, and then in a warm blanket. In this form, the banks stand until they cool. You can save this kind of workpiece at room temperature or in pantries.
It becomes clear: if you know how to roll a can with a seaming machine correctly and reliably, you can prevent various problems that lead to spoilage of homemade products.
