Bubble Leak Testing System with a Dry off Sink used for Leak Testing Large Bags

How do you leak test Large Food Bags?

This is the same question a Large Food and Beverage Processor had asked themselves because they had need for a bubble leak testing system which could be used to detect presence of leaks in their large bags. Their requirements were to test several sized bags with the largest bag being 24 inches Wide by 12 inch Deep by 9 inches High. In addition to the bubble leak testing system, they also needed a way to dry the bags after the test.

Why is leak testing done on Large Food Bags?

It is very important to leak test large bags of food for several reasons. First, a leak in the bag, will decrease the shelf life of its contents. Second, a leak will cause the contents to go stale faster resulting in decreased quality. Third, a leak is a contamination risk as it allows for bacterial, viral, and fungi to enter the contents and spoil them. The damage caused by a leaking package is far beyond the damage to the product. There is also the potential risk of soiling of customer relations, not to mention the potential for health hazards.

Fortunately, an Acrylic Bubble Emission Testing System is commonly used in the Food and Beverage industry to leak test large bags containing Hops, Soy, Corn, Wheat, or any other grain. Any bags that are non-porous and heat sealed and which required a full hermetic seal can be leak tested by a bubble leak tester.

About this Leak Testing System

Since this leak testing system is operated indoor, an oil free vacuum pump is the recommended choice because the maintenance is minimal and there are no oil mist emissions from the vacuum pump. The inside dimensions of this Acrylic Vacuum Tank are 35 Wide x 18 Deep x 12 Hight, it has a Gas Spring to Support the Lid which is kept in place during the loading and unloading of the large test bag. To the right side of the tank, you can see the dry off sink, this is where the bags are dried off after they have been dunked for the leak test. The assembly is housed on a frame structure which connects the Leak Testing Tank, the Vacuum Pump, and the Dry-Off sink. It is a complete, fully assembled system – Just Add Water.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Power Vacuum Feedthroughs
Power vacuum feedthroughs are hermetically sealed off the shelf components used to transfer electrical power from the outside of the vacuum chamber into the inside of the vacuum chamber without compromising the vacuum. One example application would be powering an electronic device inside the vacuum chamber

Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
