Fresh food preservation equipment

A fresh food preservation equipment, comprising:

• a preservation box formed with a cavity therein;
• an atomization device mounted on the preservation box for outputting water mist;
• a plasma activated droplet generation device mounted on the preservation box for ionizing the water mist output from the atomization device and feeding a resultant activated mist into the cavity;
• a refrigeration device mounted on the preservation box for reducing temperature inside the cavity;
• a sensing system comprising an oxygen sensor, a humidity sensor, and a temperature sensor for monitoring oxygen concentration, temperature, and humidity in the cavity, respectively;
• and
• a control unit electrically connected with the atomization device, the plasma activated droplet generation device, the refrigeration device, and the sensing system, respectively, for controlling operation of the plasma activated droplet generation device according to oxygen concentration information returned by the oxygen sensor, controlling operation of the atomization device according to humidity information returned by the humidity sensor, and controlling operation of the refrigeration device according to temperature information returned by the temperature sensor.
