Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a vacuum packaging machine for food processing. Background Art

[0002] Food vacuum packaging puts food into the packaging bag, and after reaching the predetermined vacuum degree, the sealing process is completed. In the food industry, vacuum packaging 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 and other various foods that need to be kept fresh are increasingly vacuum packaged. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of food. The main function of food vacuum packaging is to remove oxygen, which is beneficial to prevent food from spoiling. Its principle is also relatively simple, because food mold and spoilage are mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen to survive. Vacuum packaging uses this principle to remove oxygen from the packaging bag and food cells, so that microorganisms lose their living environment.

[0003] In the prior art, it is not convenient to automatically unload the packaged food during the vacuum packaging process, which reduces the food packaging efficiency. To this end, we propose a vacuum packaging machine for food processing to solve the above problem. Utility Model Content
