ABSTRACT:
A method for sanitizing minced meat consisting in quickly heating the minced meat by microwave heating and hot air under a pressure increasing from atmospheric pressure to an overpressure which prevents liquid evaporation, in subsequent heating of the minced meat by microwave heating up to a sterilization temperature and under constant overpressure for preventing liquid evaporation, and in finally cooling the minced meat under a pressure gradually decreasing to the atmospheric pressure, with the sterilization temperature being maintained below a threshold temperature at which the meat changes organoleptic characteristics with respect to its raw meet state. The apparatus for sanitizing the minced meat has a first, a second and a third independently operatable stations for performing the microwave heating, pressurizing and cooling operations and microwave reflective conveyance elements for supporting the meat during advancement along advancement lines of the stations and which allow liquids to drip off the treated meat.
