Description

Известные способы определени  влажности различных материалов (электрические, газометрический, высушивани  и др-) показывают суммарное содержание влаги в материале, по не могут быть применены дл  определени  только поверхностной влаги.The known methods for determining the moisture content of various materials (electrical, gasimetric, drying, etc.) show the total moisture content of the material, but cannot be used to determine only the surface moisture.

Предлагаемый способ позвол ет производить быстрое измерение поверхностной влажности различных материалов, например чайного листа, продуктов и т. п.The proposed method allows rapid measurement of the surface moisture of various materials, for example, tea leaves, products, etc.

Сущность изобретени  заключаетс  в том, что предварительно взвешенную навеску испытуемого материала опускают в воду, измер ют отградуированным в граммах дл  соответствующего материала ареометром силу, действующую на опущенную в воду навеску, и но разности между весом навески материала с ;поверхностной влажностью и без нее суд т о количестве поверхностной влажности.The essence of the invention is that a pre-weighed sample of the test material is immersed in water, a force measured on a sample dipped in water measured by a hydrometer with a surface moisture and without a court is measured with a hydrometer calibrated in grams for the corresponding material. about the amount of surface moisture.

Основанием дл  описываемого способа служит следующее соображение .The basis for the described method is the following consideration.

Сила, действующа  на навеску (равнодействующа ) при погружении ее в воду, равна разности между весом навески и выталкивающей силой, действующей на навеску, согласно закону Архимеда.The force acting on the sample (resultant) when immersed in water is equal to the difference between the weight of the sample and the buoyant force acting on the sample, according to Archimedes' law.

Эта (равнодействующа ) сила пропорциональна весу навески испытуемого материала, а в вес навески входит как составна  часть поверхностна  влага, котора  при погружении навески в воду переходит в объем воды и тем самым не вли ет на вес навески.This (resultant) force is proportional to the weight of the sample of the test material, and the weight of the sample includes as part of the surface moisture, which, when immersed in the water, goes into the volume of water and thus does not affect the weight of the sample.

Вес навески материала с поверхностной влажностью определ етс  предварительно, а вес навески без поверхностной влажности определ етс  ареометромВеличину поверхностной влажности определ ют по разности между весом навески материала с поверхностной .влажностью и без нее.The weight of the weight of the material with surface moisture is determined preliminarily, and the weight of the weight without surface moisture is determined by the areometer. The value of the surface moisture is determined by the difference between the weight of the weight of the material with and without surface moisture.

Предмет изобретени Subject invention

Способ определени  поверхностной влажности различных материалов , например зеленого чайного листа, продуктов и т. п., отличающийс  тем, что, с целью быстрого измерени  поверхностной влажности , предварительно взвешенную навеску испытуемого материала опускают в воду, измер ют отградуированнь м в граммах дл  соответствующего материала ареометром силу, действующую на опущенную в воду навеску, и по разности между весом навески материала с п оверхностной влажностью и без нее суд т о количестве поверхностной влажности .A method for determining the surface moisture of various materials, such as green tea leaves, products, etc., characterized in that, in order to quickly measure the surface moisture, a previously weighed sample of the test material is immersed in water, measured in grams for the corresponding material with a hydrometer the force acting on the sample lowered into the water and the difference between the weight of the sample of material with and without surface moisture is judged by the amount of surface moisture.
