隧道烘干线是工业领域用于批量物料连续烘干的专用设备，核心由隧道式封闭腔体、输送系统与加热控温模块构成。设备工作时，物料（如涂层工件、食品原料、电子元件等）通过输送带匀速进入封闭腔体，腔内通过电加热、热风循环或天然气加热等方式，维持稳定烘干温度（通常 50-200℃，可按需调节），实现物料水分去除或涂层固化。其隧道式结构支持不间断连续作业，配合精准温控系统，能保证不同批次物料烘干效果的一致性；部分型号可根据物料特性调整输送带速度与腔内温度分区，适配多样化烘干需求。设备操作简便、自动化程度高，能大幅提升批量生产效率，广泛应用于五金加工、食品加工、电子制造、印刷包装等领域。
The Tunnel Drying Line is a specialized equipment for continuous drying of bulk materials in the industrial field, mainly composed of a tunnel-type closed chamber, a conveying system and a heating and temperature control module. During operation, materials (such as coated workpieces, food raw materials, electronic components, etc.) enter the closed chamber at a constant speed via a conveyor belt. The chamber maintains a stable drying temperature (usually 50-200℃, adjustable on demand) through electric heating, hot air circulation or natural gas heating, realizing moisture removal of materials or coating curing. Its tunnel-type structure supports non-intermittent continuous operation, and combined with a precise temperature control system, it can ensure the consistency of drying effects for materials in different batches; some models can adjust the conveyor belt speed and temperature zones in the chamber according to material characteristics, adapting to diverse drying needs. The equipment is easy to operate and has a high degree of automation, which can significantly improve the efficiency of mass production, and is widely used in hardware processing, food processing, electronic manufacturing, printing and packaging and other fields.
