8. How Does A Vacuum Packing Machine Work?

A vacuum packaging machine is usually available in two designs:

  • Automatic design
  • Semi-automatic design

Both designs work with the same principle, the only difference is in the operations

Automatic Vacuum Sealing Machines
Automatic vacuum packing machine working principle:

  • Filled containers are inserted into the machine by the operator.
  • Parameters are set by the operator through the control panel. ( touch screen interface)
  • Vacuum pump of the machine sucks out all the air from inside after containers enter the vacuum chamber.

Semi-Automatic Manual Vacuum Sealing Machines
Semi-automatic vacuum packing machine has almost same functions like automatic vacuum packing machines, the difference lies in the operating process as the operator needs more effort in the sealing process. The sealing process is manual as the operator has to manually fill each container in the machine and seal the container with the finger, pressing the switch. This sealing process is repeated for each container.

The Double Seaming Process
Once the air is removed from the containers the double seaming process starts:

  • Compression

Can body is compressed by the machine in the direction of the seaming head holding the lid.

  • First Roller Operation

The first seaming roller interconnects the can body’s projection with the lid’s whorl to form a slack seam.

  • Second Roller Operation

The first seaming roller hideaways and therefore the second seaming roller advances and presses the seam from the primary roller operation to supply an enclosed seal

13. Can I Pack Vacuum Seal Zip Lock Bags With Vacuum Packing Machine?

Zip lock bags make it easy to close or open bags. They are useful for short time storage. Zip lock bags seal is not durable for long time storage. A vacuum sealer is recommended allowing the food to stay fresh for a long period of time. The following process should be followed while sealing zip lock bags by a vacuum packing machine

Choosing a Zip lock Bag

Suitable size and quality are required while choosing a zip lock bag. Two bags are required, one small and one large in size for a handheld machine.

Preparing the Zip lock

Zip lock preparation mainly depends on the type of vacuum sealing machine. For automatic machines, just cut off the zip lock part. For semi-automatic machines, poke 1*1 inch hole at each end of both bags.

Sealing

In the sealing process, the zip lock part is cut off from both ends. The two layers are peeled off apart and are placed inside the bag on both ends to support the bag’s seal. In the last step, the bag is placed inside the machine and turn on the machine; the rest of it will do its magic.

14. Are There Any Other Ways To Extend The Lifespan Of Food?

Following are the ways other than vacuum sealing that can increase the shelf life of the food:

Improving Treatment and Handling Procedures

After harvesting fruits and vegetables, post-harvest handling must be ensured to increase its life span e.g treatment with bad water, store in hot places or contaminated boxes. To increase life span their treatment should be done with clean water, handle with care and store in a cool dry place. Its shelf life will automatically increase. For example, apples can be store for up to 8 months in cold storage.

Cold Storage

Finding Temperature Weaknesses in Cold Chain
Another way to increase the shelf life of the product is by minimizing the depletion of cold chain temperature differences. If the cold chain is compromised the product’s life span will be reduced.
For example, after harvesting four-hour delay in precooling strawberries resulted in almost 50% of the loss. Some methods can be used to observe the temperature of the cold chain throughout the process.

Monitoring Humidity to Identify Improvement Areas
Controlling humidity also increases the shelf life of food. Humidity monitoring avoids moisture loss thus preventing food from spoiling. Refrigeration most of the time’s loss moisture content of food which is not acceptable. Proper monitoring increases the shelf life.

Monitoring room
