Seal Integrity Assessment of Coffee Bags during production Runs

Coffee is one of the most popular refreshment drinks of the world. There seems to be no end to its popularity growth. If you are a coffee processor, manufacturer, or packager, it is imperative for you to test the seal integrity of your coffee bags. The main reason is that improperly sealed coffee bags are at risk of mold development. Another reason is that a fault seal can cause the coffee to become stale.

Fortunately, there is a simple way to test for heat seal quality of your coffee bags by using a Bubble Leak Tester. This is a simple seal integrity testing unit that will allow you to perform a dry test and a wet test. The dry test is performed by pulling a vacuum and watching the coffee bags inflate. If the bag explodes, you may have a weak seal. The wet test is performed by dunking the coffee bags underwater, pulling a vacuum, and looking for bubbles emitting from the test specimen. If you observe bubbles, you have a leak.

This chamber size of the system is 12 inches diameter and 15 inch high. The vacuum pump is an Oil Free Gast Vacuum Pump capable of pulling about 22 inHg of Vacuum – this is enough in most cases to perform a dry or wet package leak test. Below the chamber is a drain valve which will enable you to drain the water from your tank without having to tip it. Next to the chamber is a Vacuum Pump that does not require much maintenance since it is oil free. This is a complete system, it is fully setup and ready to go all you need is to plug the vacuum pump in and just add water to start bubble leak testing.

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Ethernet Vacuum Feedthroughs
Ethernet Vacuum Feedthroughs are Vacuum Rated Ethernet connectors that enable you to run ethernet cables into your vacuum chamber. Simply connect your ethernet connector to the outside of the vacuum chamber and another ethernet cord from the inside and run it into your part present inside your vacuum chamber.
Our Work: Research, Development, and Testing of Weather Balloons inside a Clear Vacuum Chamber
A wonderful company (more like one of the best companies in the world) which is currently involved with the research, development, and testing of high-altitude weather balloons, had a need for a vacuum chamber capable of achieving about 100 micro Torr (Micron) of ultimate Pressure for their testing environment. Fortunately, acrylic vacuum chambers are the perfect choice when it comes to Low, Rough, and Medium Vacuum.
