为探究新疆地区红枣含水率的检测方法,运用TH2828 S 型LCR 测量仪对红枣电特性与含水率的变化进行测定,分析了红枣含水率不同频率下电特性变化,并建立红枣含水率电特性参数模型. 以整颗红枣为试验对象,在电源电压1V及纵向压力(0.1kg)下测试了低频段(200 ~1 000Hz)红枣含水率电特性参数变化规律. 试验结果表明:在含水率55.85%以下,红枣含水率与复阻抗 Z呈负相关,通过电特性参数可以实现红枣含水率检测.

To explore the detection of moisture in Xinjiang jujube, paper uses TH2828S type LCR meter changes in the electrical properties of dates and water content were measured to analyze the different electrical characteristics change dates moisture frequency, and the establishment of the moisture content of electricity dates characteristic parameters of the model.Dates with whole pieces of test subjects, the power supply voltage 1 V and longitudinal pressure ( 0.1 kg ) tested the low frequency (200Hz ~1000Hz) dates moisture variation of electrical parameters, test results show that:the mois-ture content of 55.85%or less, dates water content and the complex impedance Z is negatively correlated electrical pa-rameters can be achieved by dates moisture detection.
