Abstract

Food Storage and Preservation System with a plurality of food storage containers each with a gasketed door, each the food storage container having an air inlet port and an air outlet port, the air outlet port terminating in a solenoid valve and a vacuum limit switch, a central air treatment module in a housing, the air treatment module consisting of a vacuum pump, an ozone generator, a microprocessor and a power supply, a wire and hose harness set, said wire and harness set capable of connecting said food storage container to said air treatment module, a switch sensor that activates when said container door opens or closes, a sliding food holding tray that resides inside said food storage container, a food storage and preservation system that, when the user closes said door, first ozonates the interior of said container and then evacuates the air from said container as controlled by said microprocessor, said evacuation automatically maintained by the monitoring of said vacuum limit switch, said air treatment module being powered by a rechargeable replaceable battery, said air treatment module alternately being powered by standard household power.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . Food Storage and Preservation System comprising: 
 a plurality of food storage containers each with a gasketed door, each said food storage container having an air inlet port and an air outlet port;    said air outlet port terminating in a solenoid valve and a vacuum limit switch;    a central air treatment module in a housing;    said air treatment module consisting of a vacuum pump, an ozone generator, a microprocessor and a power supply, a wire and hose harness set;    said wire and harness set capable of connecting said food storage container to said air treatment module;    switch sensor that activates when said container door opens or closes;    sliding food holding tray that resides inside said food storage container;    food storage and preservation system that, when the user closes said door, first ozonates the interior of said container and then evacuates the air from said container as controlled by said microprocessor;    said evacuation automatically maintained by the monitoring of said vacuum limit switch; said air treatment module being powered by a rechargeable replaceable battery; said air treatment module alternately being powered by standard household power.
