THE valve applicator system Bestrom-100 is designed for applying safety valves on bags filled with coffee product.
Available from Autopac Systems Pty Ltd , the applied valve excludes air penetration into the filled bag and allows built up gas within the package to be released.
A valve-applying applicator works in combination with automatic VFFS packaging machines or can be used as a separate system to apply valves on pre-made bags.
To maintain fresh packaged coffee, oxygen must be kept out of the packaging.
The problem with the packaging of fresh roasted coffee is the out-gassing that occurs after the roasting process. The gas produced by the coffee beans can cause the seals of a package to tear apart unless the gas within the package is released. If the coffee is not packed until the out-gassing stops, then the coffee will become stale.
The valve applicator system consists of the following equipment:
* An application head
* A frame
* Assembled arm
* Pneumatics ‘Pneumax’
* Oil reservoir.
