METHOD FOR EVALUATION OF TECHNOLOGICAL CHARACTERISTICS OF MICROWAVE PROCESSING OF AGRICULTURAL MATERIALS AND FOOD Russian patent published in 1999 - IPC

FIELD: agriculture and food industry, in particular, heat testing of biological materials subjected to microwave heating. SUBSTANCE: method involves heating sample by power of microwave electromagnetic field in direction from surface inside sample, jump-wise interruption of field, measuring sample temperature at given depth in direction of field action, measuring environment temperature, measuring temperature of sample in heating region in two levels of depth, and measuring alternation of temp and density of heat flow at sample surface during cooling. Also method involves measuring density of tested sample before and after application of field in layer from surface to greater depth, as well measuring biological resistance rate for plants and animals. These data are used for judging minimal time required for their processing, efficiency and rate of microwave radiation dose, effective depth of field penetration, specific and effective microwave processing power. EFFECT: increased precision and information. 2 dwg, 1 tbl, 1 ex
