六、系统核心优势与瓶胚注塑适配性
瓶胚高速注塑干燥系统为瓶胚量产量身设计，相比常规 PET 干燥系统，在工艺适配、运行稳定、节能高效、联动智能等方面具备显著优势，完全匹配高腔数、高射速的瓶胚高速注塑需求。
The drying system for high-speed preform injection moulding is tailor-made for mass preform production. Compared with conventional PET drying systems, it has significant advantages in process adaptability, stable operation, energy saving and high efficiency, interconnection and intelligence, and fully matches the requirements of high-speed preform injection moulding with high cavity number and high injection speed.
1. **干燥品质，保障瓶胚成型
系统将切片含水率稳定降至≤20ppm，结晶度精准控制在 25%~35%，彻底避免 PET 水解降解，瓶胚无发白、气泡、雾斑等缺陷，力学性能达标，后续吹瓶良率提升至 99.5% 以上。
The system stably reduces the chip moisture content to ≤20ppm, accurately controls the crystallinity at 25%~35%, completely avoids PET hydrolysis and degradation, the preforms have no defects such as whitening, bubbles and foggy spots, the mechanical properties meet the standard, and the yield of subsequent bottle blowing is increased to more than 99.5%.
2. 集成化设计，适配车间狭小空间
三机一体集成式系统将预结晶、干燥、输送集成一体，占地仅 1~3㎡，相比分体式节省 60% 以上空间，适配瓶胚生产线注塑机密集排列的车间布局，安装便捷、管线少。
The three-in-one integrated system integrates pre-crystallization, drying and conveying into one body, covering an area of only 1~3㎡, saving more than 60% of space compared with the split type, adapting to the workshop layout with dense arrangement of injection moulding machines in the preform production line, and featuring convenient installation and few pipelines.
3. 全程密闭防吸湿，无二次污染
从原料上料到成品送注塑机，切片全程在密闭环境中运行，锁气阀、保温料斗、密闭输送机彻底隔绝环境湿空气，无二次吸湿，同时双级过滤保证热风洁净，切片无粉尘污染，满足食品医药级瓶胚要求。
From raw material feeding to finished products sent to the injection moulding machine, the chips run in a closed environment throughout the process. The air lock valve, thermal insulation hopper and airtight conveyor completely isolate the ambient humid air without secondary moisture absorption. At the same time, double-stage filtration ensures clean hot air and no dust pollution of the chips, meeting the requirements of food and pharmaceutical grade preforms.
4. 与注塑机深度联动，匹配高速节拍
系统与瓶胚注塑机、模具除露机构成整线工艺联动，可根据注塑机的开模 / 合模信号、产能需求自动调节供料速度和干燥参数，实现无间断供料，完全匹配 3~5s 的单模周期，保障生产线 24h 连续运行。
The system forms whole line process interconnection with the preform injection moulding machine and mould dehumidifier, and can automatically adjust the feeding speed and drying parameters according to the mould opening/closing signal and capacity demand of the injection moulding machine, realizing uninterrupted feeding, fully matching the 3~5s single mould cycle, and ensuring the 24h continuous operation of the production line.
5. 多重节能设计，降低生产升本
系统采用变频风机、余热回收、闭环热风循环、注塑联动供料等节能设计，相比常规干燥系统能耗降低 30%~50%；同时分子筛吸附剂使用寿命达 1~2 年，易损件更换周期长，维护成本低。
The system adopts energy-saving designs such as frequency conversion fan, waste heat recovery, closed-loop hot air cycle and injection interconnection feeding, reducing energy consumption by 30%~50% compared with conventional drying systems; at the same time, the service life of the molecular sieve adsorbent is 1~2 years, the replacement cycle of wearing parts is long, and the maintenance cost is low.
6. 智能精准控温，操作维护便捷
工业级 PLC + 触摸屏实现参数可视化、配方化管理，无需专业技术人员，操作人员可一键切换不同腔数模具的工艺参数；设备自带故障诊断、报警功能，日常维护仅需定期清理过滤器、校准传感器，操作门槛低。
The industrial PLC + touch screen realizes parameter visualization and formula management, no professional technicians are needed, and the operator can switch the process parameters of moulds with different cavity numbers with one key; the equipment has its own fault diagnosis and alarm functions, and daily maintenance only needs to clean the filter and calibrate the sensor regularly, with a low operation threshold.
