System and method for preserving red meat by plasma active water (PAW) vacuum packaging

A system for preserving red meat by plasma active water (PAW) vacuum packaging, comprising:

• a solution mixing tank, a plasma treatment chamber, a pressure regulator, an atomization spray device, a conveyor belt, a water circulation module, and a vacuum packaging module,
• wherein the solution mixing tank and the plasma treatment chamber are connected through a first pipe, the plasma treatment chamber and the atomization spray device are connected through a second pipe, and the atomization spray device and the water circulation module are connected through a third pipe;
• wherein the atomization spray device is configured to spray the PAW onto the red meat on the conveyor belt, and the vacuum packaging module is configured to vacuum-package the red meat;
• wherein the solution mixing tank is configured to prepare or store a base solution, the base solution is configured to flow into the plasma treatment chamber through the first pipe, the plasma treatment chamber is configured for excitation to generate plasma, and the plasma is configured to contact the base solution to prepare the PAW in the plasma treatment chamber;
• and
• wherein the pressure regulator is connected to the water circulation module through a fourth pipe and is connected to the second pipe between the plasma treatment chamber and the atomization spray device, to control flow and velocity of the PAW within the second pipe into the atomization spray device.
