REHEATING PREPARED FOOD SUCH AS MEAT Russian patent published in 2018 - IPC A23L5/10 G01N21/31 

FIELD: food industry.

SUBSTANCE: apparatus (10) for reheating cooked food, for example meat, is provided that comprises container (12) for receiving food to be reheated, sensing module (16), heating module (18), and processing unit (20). Sensing module is provided with an emitter arrangement (22) configured to emit at least light as first sensing radiation (SRA₁) with a first sensing peak wavelength (SWL₁) and light as second sensing radiation (SRA₂) with a second sensing peak wavelength (SWL₂). First and the second sensing radiations have different reflecting characteristics in relation with fat and protein in the food, for example meat, to be reheated. Sensing module is also provided with sensor arrangement (24) configured to detect light with the first sensing peak wavelength and light with the second sensing peak wavelength; wherein the light is reflected by the food. Heating module is configured to provide energy to the food arranged in the container by at least one heating radiation source (30) for heating the food in dependency of a determined fat/protein ratio. Processing unit is configured to determine fat/protein ratio (32) of the food arranged in the container based on the detected light reflected by the food. Processing unit is configured to determine operating parameters (38) of the heating module, and to control the heating radiation source to emit light as first heating radiation (HRA₁) with a first heating peak wavelength (HWL₁) and light as second heating radiation (HRA₂) with a second heating peak wavelength (HWL₂). Power output of the first heating peak wavelength and the second heating peak wavelength is adapted to have a different absorption characteristics relating to fat and protein of the food/meat.

EFFECT: improved result of the reheated food, for example meat, in a facilitated manner.
