Abstract
High moisture content in raw cashew nut causes deterioration of the kernel due to mould, bacteria, and enzyme action. Cashew nuts are to be dried to 6-8 % (d.b.) for storage. This paper explains the details of the Cashew nut Moisture meter designed for accurate determination of moisture content in raw cashew nuts. The Instrument works on the principle of electrolitic capacitance. Cashew acts as the dielectric of the parallel plate capacitor which is the sensor of the instrument. The moisture meter is calibrated against standard air oven method . clt can read the moisture content upto 20% (d.b).
