Ensure the sealing of food packaging
The shelf life and integrity of food mainly depends on their packaging. Due to the progress of production technology and the improvement of raw materials, composite paper cans provide the best conditions for food storage.
Can sealing is the most important quality inspection point of this kind of products: oxygen into the packaging, will make food quickly deteriorated. Therefore, the manufacturer will perform a leak test to check the tightness of the composite can.
Helium leak detection in food packaging industry
In order to check the tightness of the composite paper can, helium leak detection test was carried out according to the predetermined test plan during and after the production. Test the gas with helium and check the package for leakage. If a leak is found, stop the production of the composite can. In this case, find and eliminate the cause of leakage in the previous process.
Through the helium seal test, we can also analyze the influence of parameter changes in the production process and the influence of new raw materials and materials. In this way, products can be developed in a targeted way.
To this end, the test program has customized a vacuum solution that can be used in different versions of multiple production sites. The equipment is of modular structure and can be equipped with up to six vacuum chamber modules meeting customer requirements. The whole vacuum pump and measurement technology equipment are installed in the basic module: a rotary vane pump which vacuums the process room and test samples, and a helium leak detector smarttest 550 with independent vane pump to ensure the highest accuracy.
Here is a brief introduction to the vacuum pump for helium leak detection in the food packaging industry. For those who want to know more about the vacuum pump type, click here to contact us.
The space formed by two end covers and two rotating blades to enclose the rotor and pump cavity can be said to be the more important space of the rotary vane vacuum pump. The following section will share the space divided into three parts, and code them with a, B and C respectively.
When the rotor rotates normally, the equipment will be in the process of suction, so the volume of space B will gradually increase because of the connection with the suction port. And space a will become smaller and smaller because of its connection with the exhaust port. The volume of space C in the middle of them will also gradually decrease. When the equipment is in the compression process, the volume of space B will also slowly increase. But if you separate space B from the air intake, its volume will gradually decrease.
The above is the phenomenon of three space mutual influence in vane vacuum pump. If you want to know more about it, you can leave the phone number for Xiaobian!
