Oceania Mini Tramezzini
Our OCEANIA machine is available in the gas flush version even in the MINI model: the “gas flush” packaging technique in a protective atmosphere involves a special gas mixture being injected directly into the tray, ensuring that the atmospheric air present in it is “pushed/flushed out”; after being flushed out of the die, it is replaced by the injected mixture and the pack is sealed.
This all takes place without using the vacuum pump.
The advantage of this gas flushing technique is the speed with which a packaging cycle takes place, ensuring a higher production rate than the standard vacuum and gas version, guaranteeing, in any case, a low percentage of oxygen residue, while preserving and maintaining the initial state of freshness of the product, with a long lasting shelf-life comparable to that achieved with systems that work with vacuum and equivalent gases available on the market.
The purpose of the packaging process in a protective atmosphere is generally (except in the case of red meat packaging) to reduce the amount of residual oxygen inside the pack (it is the main cause of oxidation) and to replace it with gases such as nitrogen (inert) and carbon dioxide or other more complex mixtures suitable for the food to be packaged.
The machine in the gas-flushing version is not equipped with a vacuum pump and in addition to featuring reduced energy consumption compared to the standard version, reduced maintenance costs and greater system safety, it certainly has an advantage when used in food industries and markets involving packaging in an aseptic or controlled environment, often required by the regulations, and where a vacuum pump could over time “release” air containing impure particles and contaminants.
