近些年有的纸厂采用红外线烘干法达到了快速的目的。但需操作者自己掌握时间,也有些不便。根据这些问题,我自行设计制造了一个由电子线路自控烘干时间的小仪器(如图),时间一到,线路会自动切断红外线灯泡的电源,而且给 In recent years, some mills have adopted the infrared drying method to achieve a rapid purpose. However, the operator needs to master the time, but also some inconvenience. According to these problems, I design and manufacture a small electronic device controlled drying time of small instruments (Figure), the time comes, the circuit will automatically cut off the power of the infrared light bulb, and to
