1. 工作原理 working principle

　 它是由一个横卧的外壳和一个带有蒸汽加热的转轴构成，轴上焊有加热平板，平板上装有可调节角度的轮叶。随着轴的旋转，鱼粉在轮叶和盘管的共同作用下得到充分的搅拌和混合，从而使鱼粉同转轴平板表面接触最大。加热后产生的二次蒸汽从外壳顶部汽室通过引风管道排出，管道内保持有微弱的真空度，使蒸汽不致外泄，同时避免吸入多冷空气，蒸汽从进料口的轴端进入，冷凝水则从出粉口的轴端排出。

It is consisted of horizontally placed shell and revolving shaft with function of steam heating; The heating flat plate mounted with angle-adjustable paddle is welded to the shaft. By the force of the shaft revolution, fish meal is completely agitated and mixed. The gas generated during the heating action is vented by the air pipe in the steam chamber located at the top of shell. The air pipe is kept slightly vacuum to avoid steam leaking and too much cold air sucking. The steam enters in from the shaft-end in the inlet but the condensate discharged from the shaft end of the outlet;
