在温度为20 ~ 80℃、相对湿度为15 ~ 90%的条件下，测定了油菜和小麦的体积收缩率。随着种子含水率的降低，体积随时间呈指数递减。对于油籽油菜籽，收缩率和减湿率呈线性相关，收缩系数约为1.0。对于淀粉类谷物小麦，二者也呈线性关系，但系数大于1.3。小麦和油菜的收缩系数与干燥温度不相关，但与干燥空气的相对湿度呈线性变化。
The bulk volume shrinkage of canola and wheat were measured for the temperature range of 20–80C and relative humidity range of 15–90%. the volume decreased exponentially with time as seed moisture content was reduced. For canola, an oilseed, shrinkage and moisture reduction were linearly correlated with a shrinkage coefficient of about 1.0. For wheat, a starchy grain, the relationship was also linear but the coefficient was greater than 1.3. the shrinkage coefficients for both wheat and canola did not show a correlation with drying temperature but varied linearly with relative humidity of the drying air.
