Low oxygen gas preservation for food - replacing air in container by protective gas

摘要

Food is given a preservation treatment in a chamber where a protective gas or steam is introduced to replace the air. Outlet and/or inlet valves for the circuit are controlled in such a way that the flow is regulated as a function of pressure, quantity, time and/or temperature. This system can be easily adjusted for different types of food and can accommodate to a wide variety of sizes. Its operation can be fully or semi-automatic and it requires little maintenance.
