外殼和烘干室均用薄鋼板制成（內膽可用不銹鋼），表面噴涂烤漆及高溫銀粉漆，夾層之間襯填保溫性能良好的硅酸鋁纖維。

       加熱元件全部采用不銹鋼加熱管加熱效果好，溫度均勻。感溫元件采用K鎳鉻-鎳硅熱電偶，SME系列溫度調節儀進行測溫，控溫顯示溫度直觀;恒溫的時間控制由0~12小時控制，工作的電流電壓分別有儀表指示。

       The shell and drying chamber are made of thin steel plate (stainless steel can be used for the inner liner), the surface is sprayed with baking paint and high temperature silver paint, and the interlayer is lined with aluminum silicate fiber with good thermal insulation performance.

       All heating elements are made of stainless steel heating tubes with good heating effect and uniform temperature. K nickel chromium nickel silicon thermocouple is used as the temperature sensing element, SME series temperature regulator is used for temperature measurement, and the temperature control display is intuitive; The time control of constant temperature is controlled by 0~12 hours, and the working current and voltage are respectively indicated by instruments.
