METHOD FOR DEFINITION OF INTEGRAL ABSORPTION CAPACITY OF DISPERSIVE FOOD PRODUCTS Russian patent published in 2010 - IPC A23L3/26 A23L3/05 G01N21/00 

FIELD: food industry.

SUBSTANCE: invention relates to food industry, in particular to flour grinding, food-concentrates, cereals, confectionery, bakery, starch-and-sugar-processing and may be used for control of the process of thermal treatment of dispersive food products, such as grains, cereals, flour, sand sugar and salt. The method is implemented as follows. The dispersive food product is prepared. One forms a flat sample of the sifted layer by way of the dispersive food product sifting into a vessel. One measures environmental temperature and food product temperature on the upper surface of sifted layer. Environmental temperature is maintained around the sample at a permanent level. One performs uninterrupted infrared heating of the samplel to a specified temperature. One performs infrared treatment of the upper surface of the sifted layer sample with a radiant flux in oscillating mode. One determines temperature field on the upper surface of and inside the sample in the process of infrared heating. One determines oscillation amplitude of the sample medium temperature in the process of infrared treatment in oscillating mode. One measures the infrared energy radiant flux quantity on the sample upper surface in the process of infrared heating. One measures amplitude and frequency of oscillation of the infrared energy radiant flux on the sample upper surface in the process of infrared treatment in oscillating mode. One determines the angle of phase displacement of the radiant flux oscillation and the sample medium temperature in the process of infrared treatment in oscillating mode. One calculates integral absorption capacity of dispersive food products according to a patented formula explained in the invention formula.

EFFECT: invention allows to enhance yield of the target product, to reduce the time of technological processes implementation and to enhance precision of control of qualitative properties due to a higher precision and reliability of measurement instruments.
