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.

Vacuum Degassing Systems
Vacuum Degassing Systems enable you to remove trapped gas inside your liquids - generally, epoxies. Degassing is a vital part of any two part or more mixing process, this includes but is not limited to epoxy, pharmaceutical mixing, potting, recipe creation. A vacuum degassing system consists of a vacuum pump, connection hardware (includes filters and traps) and a vacuum chamber.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.
