Agricultural Research Station, Anantapur - 515 001, India.
The experiment was conducted during 2001–2003 to determine equilibrium moisture content (EMC) of groundnut at temperatures of 25, 35, 43°C and relative humidities ranging from 35 to 80%. Saturated solutions of various inorganic salts were employed to create the controlled himidities in the closed chamber. The equilibrium moisture content of groundnut obtained by equilibrating them at 35 to 80 per cent relative humidities (RH's) at each of the temperatures of 25, 35 and 43°C. Three EMC-ERH models namely Helsey, Harkins-Jura and Smith were fitted to the observed data and evaluated for predicted values and co-relation coefficient. All the EMC models gave good fit in the relative humidity range of 35 to 55 per cent.
