本设计的由单片机控制的自动加料系统是与料斗式干燥机配套的加料系统。根据加料工艺要求，其工作原理是：先将真空管关闭，启动电机，用低真空气流将塑料树脂粒子送入真空管，电机停转，再将粒子排入料斗，如此循环。-The design of single-chip microcomputer controlled by the automatic feeding system with hopper dryer feed supporting system. Charging process in accordance with the requirements of its working principle is: first vacuum tube to close, start motor, using low vacuum plastic resin particles will flow into the vacuum tube, the electrical switch to stop, and then particles into the hopper, and so the cycle.
