一次固化爐的基本原理是利用電作為熱能源，壓縮機組作為制冷源，由　電加熱元件產生熱量，利用風機進行對流換熱，對物料進行熱量傳遞，并不斷補充新鮮空氣，排出潮濕空氣。其最大特點是根據產品要求不同，可對溫度升高和降低進行控制

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.
