Description

Изобретение относитс к винодельческой промышлеииости, а именно к способам контрол содержани сахара в виноградном сусле.The invention relates to the wine industry, in particular to methods for controlling the sugar content of grape mash.
Известные рефратометрические способы определени содержани сахара основаны на зависимости показател преломлени света от концентрации вещества в растворе 1 .Known refratometric methods for determining the sugar content are based on the dependence of the refractive index of light on the concentration of a substance in solution 1.
Однако при таких способах не учитываетс , что плотность сусла зависит не только от количества сахара, но также и от концентрации несахаров, обусловленной районом произрастани винограда, количеством осадков в году, температурой окружающей среды, составом почвы и т. д.However, such methods do not take into account that the density of the wort depends not only on the amount of sugar, but also on the concentration of nonsugars caused by the growing area of the grapes, the amount of precipitation per year, the ambient temperature, the composition of the soil, etc.
Целью изобретени вл етс повыщение точности контрол путем исключени вли ни плотности сусла.The aim of the invention is to increase the accuracy of control by eliminating the effect of the density of the wort.
Указанна цель достигаетс тем, что через емкостный датчик пропускают электрические токи на двух частотах, соответственно /1 2 кГц и /2 200 кГц, а о содержании сахара в виноградном сусле суд т по разности выходных токов.This goal is achieved by the fact that electric currents are passed through a capacitive sensor at two frequencies, respectively 1 12 kHz and 22 200 kHz, and the sugar content of grape must is judged by the difference in output currents.
На чертеже изображена структурна схема прибора дл осуществлени предлагаемого способа.The drawing shows a block diagram of an instrument for carrying out the proposed method.
Пример. Пробу сусла наливают в емкостной датчик 1, на вход которого подведены равные и неизменные по величине синусоидальные напр жени от двух генераторов 2 и 3, соответственно с частотами /1 2 кГц и /2 200 кГц. Генераторы получают питаиие от источника 4 стабилизированного напр жеии . Выходные токи емкостного датчика на этих частотах после фильтрации фильтрами 5 и 6 и выпр млени выпр мител ми 7 и 3 поступают в рещающее устройство 9, где осуществл етс автоматическое рещение уравнени Example. A sample of the wort is poured into a capacitive sensor 1, at the input of which equal and constant sinusoidal voltages from two generators 2 and 3 are connected, respectively, with frequencies 1 2 2 kHz and / 2 200 kHz. Generators receive power from source 4 of stabilized pressure. The output currents of the capacitive sensor at these frequencies, after being filtered by filters 5 and 6 and straightened by rectifiers 7 and 3, are fed to a soldering device 9, where the automatic solution of the equation is performed.

The resulting current, equal to the difference of these currents, is fed to the input of the measuring device 10, the scale of which is calibrated as a percentage of sugar content.
Использование предлагаемого способа контрол сахаристости сусла обеспечивает по сравнению с существующим способом иовыщение точности контрол на 0,55%.Using the proposed method of controlling the sugar content of the wort provides, as compared with the existing method, the control accuracy is increased by 0.55%.
