Drying parameter effects on lentil seed viability.

Fresh Laird lentils with initial moisture contents of 16 to 20% (wet basis) were dried in a thin-layer dryer for periods up to 24 h at temperatures from 40 to 80 degrees C and relative humidities from 5 to 70%. The germination rates of the samples were evaluated four months after drying. The seeds dried at temperatures up to 66 degrees C had germination rates above 93%. Lentils suffered significant losses in germination when dried at temperatures between 66 and 80 degrees C. These losses were positively correlated to air temperature, seed initial moisture content and exposure time, and negatively correlated to relative humidity. Lentils dried at 80 degrees C lost all viability. The reductions in germination of lentils after different drying periods at 66 and 70 degrees C were simulated using the probit viability analysis, with expressions for standard deviation of seed death time developed from dynamic drying processes.
