Molecular Sieve Plastic Dryer 分子筛塑料除湿干燥机 完整介绍（中英对照）
一、中文介绍
1. 设备定义
分子筛塑料除湿干燥机，是塑胶注塑、挤出行业专用深度干燥设备，依靠分子筛吸附空气中水分，产出超低露点干燥热风，专门烘干 PET、TPU、PC、尼龙、PPS 等极易吸潮塑胶原料，解决原料水解、产品银丝、气泡、脆裂等缺陷。
2. 核心工作原理
采用双塔分子筛吸附结构，两塔交替循环工作：
1）吸附阶段：潮湿空气流经分子筛，分子筛孔隙捕捉水分子，输出低露点干风送入料桶烘干塑料粒子；
2）再生阶段：饱和吸水的分子筛塔通入高温热风，加热脱除水分，再冷却降温恢复吸附能力；
两塔自动切换，实现 24 小时连续不间断供干风。
3. 核心优势
- 露点可控，可稳定达到 - 40℃~-70℃超低露点，原料含水率能降至 20~50ppm；
- 分子筛吸附性能稳定，耐高温再生、不易粉化，使用寿命远长于硅胶干燥剂；
- 搭配热风保温料桶一体化设计，闭环干燥，隔绝外界潮湿空气；
- PLC 全自动控制，自动切换吸附再生、温湿度自动调节，无需人工值守；
- 适配高粘度、高吸潮工程塑料，适合瓶胚、光学镜片、锂电池塑胶件、医疗耗材生产。
4. 适用原料与行业
适用原料：PET、PLA、PC、PA6/PA66、TPU、PBT、PEEK、PPS 等吸湿工程塑胶；
应用行业：PET 瓶胚注塑、食品包装、光学塑料、电子连接器、医疗塑胶、化纤拉丝、改性塑料挤出。
5. 常见配套机组
单机搭配保温干燥料桶、热风风机、过滤器；大型产线可搭配中央分子筛除湿干燥系统，集中供风干燥多台注塑机原料。
二、English Introduction
Molecular Sieve Plastic Dryer
This is a deep dehumidifying drying equipment specially designed for plastic injection and extrusion industries. It adopts molecular sieve to absorb moisture in air and produce hot dry air with ultra-low dew point. It is used to dry hygroscopic plastic pellets such as PET, TPU, PC and nylon, eliminating common defects including material hydrolysis, silver streaks, bubbles and brittle finished parts.
Working Principle
Equipped with dual-tower molecular sieve system, two towers work alternately in circulation:
- Adsorption Process: Wet air passes through molecular sieve which captures water molecules, then low dew point dry hot air is delivered to hopper to dry plastic pellets.
-
Regeneration Process: High-temperature hot air blows through saturated molecular sieve tower to evaporate absorbed water. After cooling, molecular sieve regains full adsorption capacity.
Automatic switching between two towers enables 24-hour continuous supply of dry air without stop.
Main Advantages
- Stable dew point ranging from -40℃ to -70℃, moisture content of plastic materials can be reduced to 20~50ppm.
- Molecular sieve features stable adsorption performance, high temperature resistance and long service life, less pulverization compared with silica gel desiccant.
- Integrated design with heat-insulated drying hopper forms closed-loop drying system to isolate ambient humid air.
- Full-automatic PLC control, auto tower switching, automatic temperature & humidity adjustment, unattended operation.
- Perfect for high-viscosity and highly hygroscopic engineering plastics, widely used in bottle preform, optical lens, lithium battery plastic parts and medical consumables production.
Applicable Materials & Industries
Materials: PET, PLA, PC, PA6/PA66, TPU, PBT, PEEK, PPS and other hygroscopic engineering plastics.
Industries: PET preform injection molding, food packaging, optical plastic, electronic connectors, medical plastic products, fiber drawing, modified plastic extrusion.
Matching Configuration
Standard set includes heat-insulated drying hopper, hot air blower and filter. Large production lines can adopt central molecular sieve drying system to supply dry air for multiple injection machines centrally.
