二、設(shè)備核心分類與適配場景
PET 瓶胚專用干燥機根據(jù)集成度、產(chǎn)能、產(chǎn)品等級分為三大主流類型，其中三機一體集成式因占地小、控制集成、聯(lián)動性強，成為 96 腔及以上瓶胚高速注塑線的市場主流，應(yīng)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%.
三類設(shè)備均圍繞瓶胚注塑工藝設(shè)計，核心干燥原理一致，僅在結(jié)構(gòu)形式、干燥效率、品質(zhì)精度上有差異化，可精準匹配不同產(chǎn)能、不同等級的瓶胚生產(chǎn)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. 三機一體集成式（主流款）
三機一體集成式將預(yù)結(jié)晶器、除濕干燥機、密閉上料機集成于一體，結(jié)構(gòu)緊湊，占地僅 1~3㎡，是瓶胚注塑線的優(yōu)選機型。
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.
可將露點穩(wěn)定降至 - 40℃~-70℃，切片含水率控制在≤20ppm，產(chǎn)能覆蓋 0.5~8t/h，適配 48~320 腔瓶胚注塑線，支持與注塑機聯(lián)動供料，參數(shù)一鍵切換。
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.
核心優(yōu)勢：集成化高、安裝便捷、露點穩(wěn)定、聯(lián)動性強，適配車間空間狹小的高腔數(shù)高速生產(chǎn)線，兼顧效率與品質(zhì)。
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. 分體式組合系統(tǒng)（經(jīng)濟款）
分體式組合系統(tǒng)由獨立的預(yù)結(jié)晶器、除濕干燥塔、真空輸送機組合而成，可根據(jù)產(chǎn)能靈活搭配，性價比高。
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.
露點穩(wěn)定在 - 40℃~-50℃，切片含水率≤25ppm，產(chǎn)能覆蓋 0.3~3t/h，適配 32~96 腔中小產(chǎn)能瓶胚注塑線，適合瓶胚量產(chǎn)初期的生產(chǎn)線。
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.
核心優(yōu)勢：單設(shè)備維護方便、后期可擴容升級，缺點是占地稍大、參數(shù)需手動聯(lián)動調(diào)節(jié)。
Core advantages: easy maintenance of single equipment, expandable and upgradeable in the later stage; disadvantages: slightly large footprint, manual linked parameter adjustment required.
3. 真空強化式（**款）
真空強化式在常規(guī)除濕干燥基礎(chǔ)上增加真空腔室，采用負壓環(huán)境干燥，是醫(yī)藥 / 食品級瓶胚的專用機型。
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.
可將切片含水率降至≤10ppm，露點≤-60℃，干燥時間縮短 30%~50%，切片熱降解風(fēng)險極低，滿足**瓶胚的高潔凈度、高力學(xué)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.
核心優(yōu)勢：干燥精度高、品質(zhì)優(yōu)，缺點是設(shè)備造價高、維護要求嚴格，僅適用于**瓶胚生產(chǎn)線。
Core advantages: high drying precision and excellent quality; disadvantages: high equipment cost and strict maintenance requirements, only applicable to high-end preform production lines.
