Abstract
Moisture is an important parameter, which determines the quality and storability of jaggery. The standard gravimetric method of moisture determination is tedious and time consuming as well. This paper deals with a new approach of moisture content determination which is quick and reliable. It has been found that the logarithm of electrical resistance of jaggery bears a linear relationship with its moisture content. Based on this information, an electronic moisture measurement system has been designed and developed. The system consisted of a resistive transducer (a pair of insulated steel electrodes which could be inserted in solid jaggery samples to desired depth), an impedance bridge, analog signal processing units and a digital display. The change in electrical resistance of the transducer, as a function of moisture content of the jaggery is processed by the measurement system to display moisture content on digital scale. The results obtained by using moisture meter were found to be in good agreement with those obtained by standard method of moisture determination of jaggery.
