摘要
猪肉的含水率检测对猪肉市场管理、贮藏和加工有很大的意义。为快速检测猪肉含水率,采用电容法设计并制作单一平面电容传感器探头和硬件电路,采用干燥法制作标准含水率样品,对传感器进行标定与验证试验。试验结果表明,利用电容法可以快速检测猪肉的含水率,含水率在60%～76.4%,测量误差±1.2%以内。温度特性试验表明猪肉的介电常数受温度影响很小,在常温范围内温度影响可以忽略。该研究可为猪肉市场管理、贮藏和加工提供参考。
Determination of pork moisture content is of great significance to pork market management, storage and processing. To quickly detect pork moisture content, a uniplanar capacitance sensor probe with hardware circuit was designed using capacitance detection method in this study. The standard moisture samples were prepared by oven drying method. The calibration experimental results showed that the proposed method can determine pork moisture content quickly for moisture contents were in the range of 60%-76.4% with less than ±1.2% error. The temperature experiments showed that the pork dielectric constant was slightly affected by temperature. The effect of temperature can be neglected within the normal temperature.
