2020-05-27
What are the categories of vacuum packaging machines? The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be filled with nitrogen or other mixed gas, and then the sealing process can be completed. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation.

The vacuum packaging machine is a packaging equipment, belonging to the category of equipment accessories. It can automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be refilled with nitrogen or other mixed gas, and then the sealing process can be completed. Vacuum packaging machine is often used in food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation. So, how is it classified according to its basic use,

Vacuum, a term translated from Latin vacuo, means nothingness. In fact, vacuum should be understood as a space with thin gas. In a given space, the state of gas below an atmospheric pressure is called vacuum. The rarefied degree of gas in vacuum state is called degree of vacuum, which is usually expressed by pressure value. Therefore, vacuum packaging is not completely vacuum in fact. The vacuum degree in the food container packed by vacuum packaging technology is usually 600-1333pa. Therefore, vacuum packaging is also called vacuum packaging or exhaust packaging.

1. Food vacuum packaging machine. This kind of vacuum packaging machine should control the temperature before vacuum packaging, and the equipment has its own cooling system, so it has higher requirements for preservation.

2. Medical vacuum packaging machine. This kind of vacuum packaging machine should have the form of vacuumizing which can keep the product for a long time; because the medical vacuum packaging machine should be used in the places with high requirements such as dust-free sterile workshop, this kind of vacuum packaging machine can also be used in the food packaging with aseptic requirements to achieve good results.

3. Vacuum packaging machine for electronic products. Vacuum packaging machine can be used for electronic products to prevent moisture, oxidation and discoloration of internal metal processing parts.

4. Tea vacuum packaging machine. This is a set of weighing, external packaging, internal packaging in one machine. The birth of tea vacuum packaging machine marks a big step to improve the level of tea packaging in China, and truly realize the standardization of tea packaging.
