一次固化炉的基本原理是利用电作为热能源，压缩机组作为制冷源，由　电加热元件产生热量，利用风机进行对流换热，对物料进行热量传递，并不断补充新鲜空气，排出潮湿空气。其最大特点是根据产品要求不同，可对温度升高和降低进行控制

The basic principle of the primary curing oven is the use of electricity as a thermal energy source, the compressor group as a cooling source, heat generated by the electric heating element, convection heat transfer using a fan, heat transfer of the material, and continuous replenishment of fresh air and discharge of humid air. Its biggest feature is that it can control the temperature increase and decrease according to different product requirements.
