METHOD OF PACKED FOOD PRODUCT WARMING Russian patent published in 2009 - IPC A47J36/28 B65D81/34 

FIELD: food industry.

SUBSTANCE: invention relates to food industry namely to method of warming of packed food product while using warmth produced during exothermal reaction. Flat thermal module is made with a neck. It contains solid reagent and is placed respectively pack with food product with thermal contact of first of two pack walls and first of two heat-transfering walls of flat thermal module provided. Exothermal chemical reaction is instigated in flat thermal module cavity by supply of fluid reagent. Warmed up vapour-gas mixture produced as a result of exothermal reaction and coming through the neck is warming up the second wall of the food product package by bending of previously flattened neck area of flat thermal module around food product package side segment. Flat thermal module which heat-transferring walls are made of sheet, flexible, heat-conducting material and hermetically connected around the opened loop is used. Conjointly connected neck and reagent solid cavity are formed. Neck segment length is at least 1.4 times longer than food product package thickness.

EFFECT: increased temperature distribution regularity is obtained around the warmed up food product with simultaneous reduce of its warming time.
