Packing in glass in a chamber vacuum sealer
Vacuum packing in glass
Times when a chamber vacuum sealer was exclusively used to extend shelf life are far behind us. On the Henkelman website you will find a lot of information about applications like, wet aging, marinating, infusion and much more. The topic of current interest is: vacuum packing in glass jars.
In a Henkelman CombiVac machine, you can vacuum pack perfectly in glass preserving jars and also in glass jars with screw lids. Many customers have discovered this application and are benefiting from it, on a small but increasingly also on a large scale. The glass can be reused and glass is also recyclable. An important argument for many to choose this form of vacuum packaging.
Let's give a few examples: the trend goes increasingly towards healthy eating. The Poke Bowl has therefore become a hype. Products that can be processed in such a Poke Bowl are sliced leaf lettuce, avocado, apple. When such a Poke Bowl is now vacuum-packed in a weck jar, the avocado remains green, the apple does not turn brown and the lettuce does not go limp. These Poke Bowls can be served in this way in bistros, but also sold to-go in the same bistro or in petrol stations, snack bars, food trucks and company canteens for example.
How can you keep your homemade croutons crispy for a long time so that you can make a larger batch in one go? Vacuuming in glass jars is the best solution!
In South Africa, Biltong is a national snack. These air-dried strips of meat have a limited shelf life. When they are tightly packed in a vacuum bag the Biltongs are compressed into a lump. Gasflushing would then be an option. Now you see more and more vacuum-packed Biltong in glass jars on the shelves in the stores,. The shelf life is extended, the Biltongs remain loose and the presentation of the product is very attractive.
How does it work?
Vacuum packaging in glass works as follows: take a glass jar with a sealing ring in the lid. Put your product in the glass and close the lid of the jar. Do not over-tighten the screw lid. Place the glass jars in your Henkelman's chamber and select the special program. Now close the lid of the machine and the machine draws a vacuum. The air is drawn from the jar. The chamber is then decompressed and the lid of the jar automatically presses onto the glass jar, because of the pressure difference between the jar and the chamber.Watch the video
