A method and system for dry aging the meat product uses a 12 volt DC powered portable unit comprising a plastic box configured for housing the primal cut of meat and placed inside a refrigeration system. The box is further equipped with an internal and external blower to control the air circulation and humidity respectively inside the box. A germicidal UV light disposed within the plenum in front of the internal blower to provide germicidal action on the dry aging meat product. A PCB controller placed on top of the box embedded with software and a humidistat to control the humidity inside the box and maintaining a closed micro environment to dry age the meat product with desired texture, flavor and tenderness.
