FOOD PRESERVATION SYSTEM

摘要

The present invention relates to using a food preservation gas to flush ambient air from a food retaining space in a container, and replacing the ambient air with the food preservation gas without having to utilize a vacuum to remove ambient air like previous systems. This allows a simple home device to be utilized where previous systems were larger and more expensive.

主权项

1. A system for food preservation comprising:
a) a sealable food container having a food retaining space of a specific volume and having a one-way inlet valve for introducing one or more preservation gases into the food retaining space and a one-way outlet valve which lets gas out of the food retaining space if the pressure in the space exceeds a predetermined amount; and b) a gas introduction module for introducing one or more preservation gases into the food retaining space comprising:
i. at least one gas canister comprising one or more food preservation gases;ii. a gas regulator regulating gas in each of the at least one gas canister;iii. a connector for connecting a single gas canister to the one-way inlet valve for introduction of the one or more preservation gas in a single canister into the food retaining space;iv. a valve for opening and closing the gas canister;v. a time control circuit for opening and closing the electronic value for a set period of time.
