In the food industry, the application of vacuum packaging machines is very common. Various cooked products such as chicken legs, ham, sausages, grilled fish fillets, beef jerky, etc.; pickled products such as various pickles, bean products, preserved fruits, etc. Food is increasingly being vacuum-packed. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of the food.
What are the operation steps of the vacuum packaging machine?
What are the safety measures for the use of vacuum packaging machines?
What is the working principle of vacuum packaging machine?
1. Turn on the power: toggle the power selection switch as needed, that is, the power indicator light is on. The power selection switch points to vacuum for vacuum sealing, and points to vacuum inflation for vacuum inflatable sealing.
2. Put the plastic bag with the items in the vacuum chamber. The bag mouth is neatly placed on the heat seal (if it is used for inflatable packaging, at least one nozzle should be inserted into the bag mouth).
3. Press down the cover, the air extraction (vacuum) indicator on the panel is on. The vacuum pump starts to pump air, and the cover is automatically sucked. The vacuum knob can adjust the degree of vacuum according to the packaging requirements. When adjusting, it depends on the scale from low to high. , the magnitude is smaller.
4. When the pumping reaches the set time (that is, the required vacuum degree), the pumping is over, the pumping indicator is off, and the inflation indicator is on, indicating the beginning of inflation. The inflation knob can adjust the length of inflation time (that is, inflation). The method is the same as above. If you do not need to inflate, turn the power switch to the vacuum position, the program will automatically enter the vacuum packaging, and the inflation indicator will turn off.
1. Keep the use environment of the vacuum packaging machine clean and tidy, and the use environment should not be too humid.
2. Do not use the vacuum packaging machine in harsh environments such as flammable and explosive.
3. The three-phase four-wire machine should be equipped with the same type of socket that matches the power supply of the machine, and should meet the requirements of the three-phase four-wire power supply; the single-phase machine should be equipped with a three-pole power socket, and the machine should be reliably grounded.
4. Unplug the power plug when overhauling the vacuum packaging machine to prevent electric shock.
The main function of the vacuum packaging machine is to remove oxygen to help prevent food spoilage. The principle is relatively simple, because the mildew and spoilage of food is mainly caused by the activities of microorganisms, and the survival of most microorganisms (such as mold and yeast) is necessary. Oxygen, and vacuum packaging uses this principle to pump out the oxygen in the packaging bag and food cells, so that microorganisms lose the environment for survival. Experiments have shown that when the oxygen concentration in the packaging bag is less than or equal to 1%, the growth and reproduction rate of microorganisms will drop sharply. When the oxygen concentration is less than or equal to 0.5%, most microorganisms will be inhibited and stop multiplying.
The widespread use of vacuum packaging machines has continuously increased the demand for them in the market. ZHEJIANG HONGZHAN PACKING MACHINERY CO., LTD, as a Chinese pioneer in vacuum packaging machine, can ensure the machines’ quality and after-sales service.
