The rate of drying of single layers of sugar beet cossettes has been found to vary markedly with temperature of the drying air from 140 to 220° F, and to increase slightly with a fourfold increase of air velocity, while humidity changes have little effect. The rate of drying is proportional to the total moisture content of the cossettes. A method of predicting the rate of drying of cossettes in beds up to 9 in. deep is given, for air velocities in the range 6–21 lb./sq. ft./min., for temperatures of 140 to 220° F, and humidities up to 40% R.H. The accuracy of the method is shown to be within +‐15%. Observations have also been made on the variation of internal temperature with change of moisture content and air temperature, and on the evidence of caramelization.
