The Difference Between Vacuum Can Sealing Machine And Vacuum Nitrogen Filling And Sealing Machine

The Difference Between Vacuum Can Sealing Machine And Vacuum Nitrogen Filling And Sealing Machine

The can sealing machine is one of the indispensable equipment in the production process of food, medicine, chemical and other industries. In the field of food packaging, vacuum can sealing machine and vacuum nitrogen filling and sealing machine are two common types of vacuum equipment. But they are different in principles, functions and usage scenarios. Below, we will discuss them one by one.

Utrustpack is a company specializing in the production of can sealing machines. The series of vacuum sealing machines designed and developed by Utrustpack are efficient, stable and highly automated equipment.

Ⅰ. Vacuum Can Sealing Machine

This machine is a kind of equipment that uses micro-negative pressure technology to seal cans. Its principle is that when the can is in a vacuum chamber, the air is pumped out and the can is sealed, a negative pressure is formed in the can. If high-temperature sterilization is needed in the next process, there will be no excess air in the can, which will cause the can to explode or bulge. Moreover, the vacuum degree can reach -40kpa after sealing, thus achieving the effects of preservation and anticorrosion.

The vacuum can sealing machine is mainly suitable for vacuum sealing of round cans of various canned fruits, canned meats, canned pet food, canned seafood, etc.

The advantages of this machine are high sealing speed and excellent sealing effect, and the products after sealing are not easy to go bad, damp and deform. What’s more, the use cost of it is also relatively low, which is suitable for small and medium-scale enterprises.

Ⅱ. Vacuum Nitrogen Filling And Sealing Machine 

This machine uses vacuum and nitrogen to seal cans. Its principle is to evacuate air first and then fill nitrogen. Nitrogen is an inert gas, which can effectively prevent oxidation and bacterial growth, etc.

The vacuum nitrogen filling and sealing machine is suitable for sealing some food, medicine, cosmetics and other products that are susceptible to oxidation, such as milk powder, dairy products, juice, beer, and etc.

The advantage of this machine is the excellent sealing effect, the products after sealing are not easy to go bad, damp and deform, and maintains the original taste and nutrients. The use cost of the vacuum nitrogen filling and sealing machine is relatively high and is suitable for large enterprises.

Ⅲ. The difference between Vacuum Can Sealing Machine and Vacuum Nitrogen Filling And Sealing Machine 

1. Different principles: The vacuum can sealing machine uses micro-negative pressure technology to seal cans, while the vacuum nitrogen filling and sealing machine uses vacuum and nitrogen to seal cans.

2. Different usage scenarios: The vacuum can sealing machine is suitable for some products that are not susceptible to oxidation, while the vacuum nitrogen filling and sealing machine is suitable for some products that are susceptible to oxidation.

3. Different working modes: The working mode of the vacuum can sealing machine is vacuum sealing; the working mode of the vacuum nitrogen filling and sealing machine is vacuum sealing, vacuum filling and nitrogen sealing.
