In the drum dryer drying process, due to the restrictions of the conditions, it is difficult to be sampled at different positions within the drum dryer for measuring first hunting Turf segment moisture, and this measured value in the optimization of drying parameters and dryer structure great significance, through computer simulation, can be solved first KAI Turf segment moisture in each unit, to replace the actual measurement value to the simulation results, in order to solve this problem, Figure 4-2 is in the inlet velocity 14m / s, inlet first layer of drum materials dry air flow temperature of 350 ° C, speed 12r/min simulated case, a moisture content of 79% of the materials from the entrance, near the entrance to the temperature of the air is high, the material with high moisture content, the drying speed quickly, with the first hunting grass segment declining moisture whereabouts stage forward distance increasing airflow temperature with the thermal energy consumption is reduced, the drying rate of the material is declining, so Figure 4 - 2, all points on the connection the slope continuously decreases.
