Description
Изобретение относитс к измерению содержани влаги и св зано с подготовкой проб сыпучих пищевых продуктов дл градуировки влагомеров. .The invention relates to the measurement of moisture content and is associated with the preparation of bulk food samples for the calibration of moisture meters. .
Цель изобретени - сокращение времени подготовки проб сыпучих пищевых продуктов.The purpose of the invention is to reduce the time of sample preparation of bulk foods.
На фиг. 1 представлен график, показывающий процесс стабилизации диэлектрической проницаемости м сокостной муки, увлажненных в атмосфере с различным содержанием влаги, во времени (влажность проб м сокостной муки, W, %: крива 1 4,1 крива 2 6;5, крива 3 8,0; крива 4 9,5)i на фиг, 2 - график $ показывающий процесс стабилизации диэлектрической проницаемости проб сухого обезжиренного молока, увлажненных в атмосфере с различным содержанием влаги, во времени (влажность проб сухого молока, w, %: крива 5 6,45, крива 6 5,10; крива 7 4,36),FIG. 1 is a graph showing the process of stabilization of the dielectric constant of m-flour flour moistened in an atmosphere with different moisture content over time (moisture content of m-flour flour samples, W,%: curve 1 4.1 curve 2 6; 5, curve 3 8.0 curve 4 9.5) i in FIG. 2 is a graph showing the process of stabilizing the dielectric constant of samples of skimmed milk powder moistened in an atmosphere with different moisture content over time (humidity of samples of powdered milk, w,%: curve 5 6.45 , curve 6 5.10; curve 7 4.36),
Процесс -необходимой стабилизации диэлектрической проницаемости проб после гигротермического увлажнени , и, таким образом, соответствие их пробам, полученным в естественных услови х , обусловлен тем, что в искусственно увлажненных пробах требуетс некоторое врем дл св зи влаги с продуктом. При св зи влаги с продуктом (процесс адсорбции) вгвдел етс тепло, так как потен;циальна энерги The process of stabilizing the dielectric constant of the samples after hygrothermal moistening, and thus their compliance with the samples obtained under natural conditions, is due to the fact that in artificially moistened samples it takes some time to connect the moisture to the product. When moisture is associated with the product (adsorption process), heat is embedded, since the potential energy

Характер режима охлалодени должен обеспечить интенсивный отвод тепла (тепловой энергии адсорбции) , выдел ющего при св зывании воды продуктом и определ емого количеством св занной влаги . Таким образом, охлаждение обеспечит ускорение процесса св зывани воды и обусловит тем ускорение стабилизации диэлектрической проницаемости пробы, т.е. сократит врем подготовки пробы в 3-5 раз.The nature of the cooling regime should provide for an intense heat removal (heat energy of adsorption), which is released when water is bound to the product and determined by the amount of bound moisture. Thus, cooling will accelerate the process of water binding and will thereby accelerate the stabilization of the dielectric constant of the sample, i.e. shorten the sample preparation time by 3-5 times.
Применение предлагаемого способа позволит получить пробы дл градуировки влагомеров, не прибега к изменению регламентированных режимов технологического процесса производства продуктов, а также сократит врем градуировки влагомеров.The application of the proposed method will allow to obtain samples for the calibration of moisture meters, without resorting to changing the regulated modes of the technological process of production of products, as well as shorten the calibration time of moisture meters.
