| Abstract: | The relationship between calefactive velocity, distribution uniformity of temperature and wind speed of heating wheat in a dryer with far infrared electric heating tube inside was studied in this paper by single factor experiment and orthogonal experiment of 4 factors and 2 levels. The results indicate that both the calefactive velocity of wheat layer inside the dryer and the difference in temperature between inner and outer layer reduce with the wind speed rising, but the difference in temperatures increases at first and then reduce with the heating time. The rule of the distribution uniformity of the temperature and calefactive velocity affected by each factors was concluded though the orthogonal tests. |
