A method for the long-term preservation and protection of items of all kinds, such as cereals and starchy substances, various grains and maslins, chemicals, explosives, textiles, paper, leather, wood, antiques, etc. from destructive animals and organisms, oxygen, moisture, insects, ageing, natural deterioration, self-explosion, fire, etc. According to the method, the items to be conserved are placed in an airtight preservation chamber from which a maximum amount of air is extracted and immediately replaced with inert gas from a gas cylinder connected to the chamber. This gas remains mixed with the items throughout the preservation period. To add or remove items, the inert gas is first drawn out of the chamber by means of a pump and compressed into said cylinder, then replaced with ambient air. Said chamber can be a box, part of a warehouse, a glass cabinet, a tank, or any other kind of airtight construction or shelter. The method allows the same quantity of gas to be used an infinite number of times without causing air pollution, and can be adapted to various currently used preservation chambers once the necessary alterations have been made. |
