Abstract. The grain bulk status was impacted by many factors. Otherwise, moisture and temperature are two more important factors. The wheat, which was sealed in the insulation storage bin, was researched in the paper. The wall temperature of the bin was 45℃, and the opposite‘s was 15℃. The others were adiabatic insulation. Therefore the wheat bulk was in the condition of constant temperature differences. The results indicated that the moisture was lower and lower nearer to 45℃ wall. However the moisture of the middle part was decrease and then increase. The moisture change of adjacent 15℃ wall was similar to the middle‘s. But it would be saturated. Moreover the temperature migration was faster than the moisture‘s in wheat bulk. When the temperature of different positions was steady in wheat bulk, the high temperature was moisture loss. Inversely the low temperature district was water accumulation. So the condensation easily happened in low temperature part in grain bulk. The condensation would be predicted by the moisture change in the wheat bulk.
