Features and operation steps of vacuum packaging machine

30-11-2019

       In the food industry, vacuum packaging machines are widely used. Vacuum packaging machines are required for various cooked products such as chicken legs, ham, sausages, grilled fish fillets, and beef jerky. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of the food. The following are the features and operation steps of vacuum packaging machine.


  Vacuum packaging machine features


  1. Excluded part of the air (oxygen) in the packaging container, which can effectively prevent food spoilage.


  2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid weight loss and taste loss of food and prevent secondary pollution.


  3. The gas inside the vacuum packaging container has been eliminated, which accelerates the conduction of heat. This can improve the efficiency of thermal sterilization and prevent the packaging container from rupturing due to the expansion of the gas during heating and sterilization.

  Vacuum packaging machine operation steps


  1. Turn on the power: Turn the power selection switch as required, 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 inflation sealing.


  2. Put the plastic bag containing the articles in the vacuum chamber. The mouth of the bag should be placed neatly on the heat seal (for inflatable packaging, at least one nozzle should be inserted into the mouth of the bag).


  3. Press down the cover, and the suction (vacuum) indicator on the panel lights up. The vacuum pump starts to pump, and the cover is automatically sucked. The vacuum knob can adjust the vacuum level according to the packaging requirements. When adjusting, the visual scale is from low to high. , The amplitude should be small.


  4. When the pumping time reaches the set time (that is, the required vacuum degree), the pumping end, the pumping indicator goes out, and the inflation indicator lights up to indicate the start of inflation. The inflation knob can adjust the length of inflation (that is, inflation) The method is the same as above. If no inflation is required, set the power switch to the vacuum position, the program will automatically enter the vacuum packaging, and the inflation indicator will go out.


  5. When the air extraction or inflation is completed, the indicator light goes out, and the heat seal indicator light is on, that is, the sealing process is entered. The panel is equipped with a heat seal time and temperature adjustment knob to adapt to different thickness materials. The dynamic range should be small to prevent the heat-sealing temperature from rising suddenly and burn out the heat-sealing accessories.


  6. When the set heat-sealing time is reached, the heat-sealing indicator goes out and ends as the heat-sealing, that is, the vacuum chamber enters the atmosphere through the solenoid valve until the cover is automatically lifted, and the vacuum inflation packaging process is all over, ready for the next Packaging cycle.


  The above is the introduction of the characteristics and operation steps of the vacuum packaging machine. I hope everyone will understand the characteristics and operation steps of the vacuum packaging machine, which will be helpful to everyone.
