Matter and energy exchanges take place between the substance and the drying air in this kind of drying. To quantify these exchanges, a series of tests were carried out at a production site in Cote dIvoire using a portable laboratory drier. It was thus possible to work on rubber that had not been denaturated by transport. Tests were performed at a range of temperatures from 40 C to 120 C with air velocity from 0.5 m/s  to 2.5 m/s and relative humidity values varying from several percent to 90 percent according to the temperature. Analysis of the drying kinetics led to modelling the matter exchange coefficient. Energy exchange coefficient was determined using measurement of the temperature of air flowing between the grains and measurement of the temperature of the grains themselves.  aDrying  aNatural rubber latex  aBenet J C  aBenoit J M  aBerthomieu G
