对小麦、大豆、豌豆种籽进行了一系列干燥试验,通过试验结果对脉动流化床干燥的空气动力学特性和干燥特性进行了分析。提出了干燥速率与干燥介质温度、气流表观速度、床层静止高度、气流脉动频率以及气流分布板开孔率之间的关系,同时也得出了床层压降与床层静止高度的关系。 A series of drying experiments were conducted on wheat, soybean and pea seeds. The aerodynamic characteristics and drying characteristics of pulsating fluidized bed drying were analyzed by the test results. The relationship between the drying rate and the temperature of the drying medium, the apparent velocity of the air flow, the resting height of the bed, the pulsation frequency of the air flow and the opening ratio of the airflow distribution plate are also presented. At the same time, the relationship between the bed pressure drop and the resting height of the bed .
