What are the specific steps of using the vacuum packaging machine?

1. Turn on the power supply and toggle the power selection switch as needed, that is, the power indicator light is on. The power selector switch points to vacuum for vacuum sealing, and points to vacuum inflation for vacuum inflation sealing.

2. Place the plastic bag containing the items in the vacuum chamber, and the mouth of the bag is neatly placed on the heat seal (if it is inflatable packaging, at least one nozzle should be inserted into the mouth of the bag).

3. Press down the cover, and the air extraction (vacuum) indicator light on the panel is on. The vacuum pump starts to pump, the cover is automatically sucked, and the vacuum knob can adjust the vacuum level according to the packaging requirements.

4. Bag the products that need to be vacuum-packed, then put the open end on the sealing strip and pay attention to keep the bag straight, if it is a small bag packaging, it can also be packed side by side with multiple bags at the same time.

5. When the pumping reaches the set time (i.e., the required vacuum), the pumping is over, the pumping indicator is extinguished, and the inflation indicator is on to indicate the start of inflation. The inflation knob adjusts the length of inflation time (i.e. how much it is inflated) in the same way as above. If you don't need to inflate, turn the power switch to the vacuum position, the program will automatically enter the vacuum packaging, and the inflation indicator will go out.

6. When pumping or filling is completed, the indicator light will be extinguished, and the heat sealing indicator light will be on, that is, it will enter the sealing procedure, and the panel is equipped with a heat sealing time and temperature adjustment knob to adapt to different thick and thin materials, and when adjusting the time and temperature, the rotation amplitude should be small to prevent the heat sealing temperature from suddenly increasing and burning out the heat sealing accessories.

7. When the set heat sealing time is reached, the heat sealing indicator is extinguished, and the heat sealing is over, that is, the vacuum chamber enters the atmosphere through the solenoid valve, until the cover is automatically lifted, and the vacuum inflatable packaging process is all over, ready for the next packaging cycle.

Hello, can vacuum packaging be achieved without vacuum packaging machine? Recently, a small video screen on the Internet has become popular,Only a bag + water is needed to form a simple vacuum packaging, netizens have a big brain. Because people see that the bag is shriveled, they think that Xunyu is in a vacuum.

But this is not really vacuum packaging, it is a pseudo-vacuum. That is, it does not meet the standard of vacuum. The meaning of vacuum refers to the state of a gas with a pressure of less than one atmosphere in a given space.

The method of vacuum packaging that can be realized without a vacuum packaging machine circulating on the Internet is similar to that of a vacuum packaging machine, which is to exhaust the air in the packaging bag. But the effect is far from perfect. It can be said that the real packaging has not been realized.

Here are a few of them:

1. Use water pressure to put the bag containing the items into the water. Water pressure is used to squeeze the air out of the bag. Then seal.

2. Use a straw to suck out the air in the bag. This applies to the items in the small Tong Chang bag. If the bag is bigger, you won't be able to suck it up. Of course, even if it looks like it's finished, it doesn't reach a vacuum.

The "vacuum packing" method described above is only a stopgap measure. If vacuum packaging is often used, suitable for storage and transportation, a professional vacuum packaging machine is also required.

The main function of food vacuum packaging is to remove oxygen, which is conducive to preventing food deterioration, and its principle is relatively simple, because food mold and deterioration are mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen for survival, and vacuum packaging is to use this principle to extract the oxygen in the packaging bag and food cells, so that microorganisms lose the environment for survival.
