PET瓶胚干燥设备

二、设备核心分类与适配场景
PET 瓶胚专用干燥机根据集成度、产能、产品等级分为三大主流类型，其中三机一体集成式因占地小、控制集成、联动性强，成为 96 腔及以上瓶胚高速注塑线的市场主流，应用占比超 80%。
According to integration, capacity and product grade, PET preform special dryers are divided into three mainstream types. Among them, the three-in-one integrated type has become the market mainstream for high-speed preform injection lines with 96 cavities and above due to its small footprint, integrated control and strong interconnection, with an application share of more than 80%.
三类设备均围绕瓶胚注塑工艺设计，核心干燥原理一致，仅在结构形式、干燥效率、品质精度上有差异化，可精准匹配不同产能、不同等级的瓶胚生产需求：
All three types of equipment are designed around the preform injection moulding process with the same core drying principle, and only differ in structural form, drying efficiency and quality precision, which can accurately match the preform production needs of different capacities and different grades.
1. 三机一体集成式（主流款）
三机一体集成式将预结晶器、除湿干燥机、密闭上料机集成于一体，结构紧凑，占地仅 1~3㎡，是瓶胚注塑线的优选机型。
The three-in-one integrated type integrates the pre-crystallizer, dehumidification dryer and airtight feeder into one body, with a compact structure and an area of only 1~3㎡, which is the preferred model for preform injection lines.
It can stably reduce the dew point to -40℃~-70℃, control the moisture content of chips to ≤20ppm, and the capacity covers 0.5~8t/h, suitable for 48~320 cavity preform injection lines.
可将露点稳定降至 - 40℃~-70℃，切片含水率控制在≤20ppm，产能覆盖 0.5~8t/h，适配 48~320 腔瓶胚注塑线，支持与注塑机联动供料，参数一键切换。
It can stably reduce the dew point to -40℃~-70℃, control the moisture content of chips to ≤20ppm, and the capacity covers 0.5~8t/h, suitable for 48~320 cavity preform injection lines, supporting linked feeding with injection moulding machines and one-key parameter switching.
核心优势：集成化高、安装便捷、露点稳定、联动性强，适配车间空间狭小的高腔数高速生产线，兼顾效率与品质。
Core advantages: high integration, convenient installation, stable dew point, strong interconnection, adapted to high-cavity high-speed production lines with narrow workshop space, balancing efficiency and quality.
2. 分体式组合系统（经济款）
分体式组合系统由独立的预结晶器、除湿干燥塔、真空输送机组合而成，可根据产能灵活搭配，性价比高。
The split combined system is composed of independent pre-crystallizer, dehumidification drying tower and vacuum conveyor, which can be flexibly matched according to capacity with high cost performance.
露点稳定在 - 40℃~-50℃，切片含水率≤25ppm，产能覆盖 0.3~3t/h，适配 32~96 腔中小产能瓶胚注塑线，适合瓶胚量产初期的生产线。
The dew point is stable at -40℃~-50℃, the chip moisture content is ≤25ppm, the capacity covers 0.3~3t/h, adapted to 32~96 cavity small and medium capacity preform injection lines, suitable for production lines in the early stage of mass preform production.
核心优势：单设备维护方便、后期可扩容升级，缺点是占地稍大、参数需手动联动调节。
Core advantages: easy maintenance of single equipment, expandable and upgradeable in the later stage; disadvantages: slightly large footprint, manual linked parameter adjustment required.
3. 真空强化式（**款）
真空强化式在常规除湿干燥基础上增加真空腔室，采用负压环境干燥，是医药 / 食品级瓶胚的专用机型。
The vacuum enhanced type adds a vacuum chamber on the basis of conventional dehumidification drying and adopts negative pressure environment for drying, which is a special model for pharmaceutical/food-grade preforms.
可将切片含水率降至≤10ppm，露点≤-60℃，干燥时间缩短 30%~50%，切片热降解风险极低，满足**瓶胚的高洁净度、高力学性能要求。
It can reduce the chip moisture content to ≤10ppm, the dew point to ≤-60℃, shorten the drying time by 30%~50%, and the risk of chip thermal degradation is extremely low, meeting the high cleanliness and high mechanical performance requirements of high-end preforms.
核心优势：干燥精度高、品质优，缺点是设备造价高、维护要求严格，仅适用于**瓶胚生产线。
Core advantages: high drying precision and excellent quality; disadvantages: high equipment cost and strict maintenance requirements, only applicable to high-end preform production lines.
