Deqing Leixin Coating Equipment Co., Ltd., established in 2011, is a specialized manufacturer of plastic auxiliary machinery with ISO9001 certification. Our factory spans 1,000-3,000 square meters, employing 51-100 skilled workers, and exports over US$1 million annually to markets across North America, South America, Europe, Southeast Asia, and more. The Automatic Plastic Raw Material Drying Machine is designed to efficiently remove moisture from plastic resins before the molding process, ensuring high-quality output and reducing defects. This machine integrates advanced dehumidification technology with automated controls, making it an essential solution for injection molding, extrusion, and blow molding lines.
Key Features & Technical Specifications
High-efficiency dehumidification: Uses a twin-bed desiccant dryer to achieve dew points as low as -40°C, removing moisture down to 0.02% to prevent hydrolysis and improve mechanical properties.
Automatic temperature control: PID controller maintains precise drying temperature (65°C-160°C) suitable for hygroscopic materials like PET, PA, PC, ABS, and POM.
Energy-saving design: Insulated hopper and closed-loop air circulation reduce heat loss by up to 30% compared to conventional dryers.
PLC touch screen operation: Intuitive interface allows setting of drying time, temperature, and airflow; alarms for low material level or filter blockage.
Robust construction: Stainless steel hopper and piping resist corrosion; optional spiral conveyor for automatic loading from storage silos.
Flexible capacity: Available in 25kg, 50kg, 100kg, 200kg, 500kg, and 1000kg models to match production throughput.

| LXD-200 | 200 | 65-160 | 2.2 | 4.0 |
| LXD-500 | 500 | 65-160 | 4.0 | 7.0 |
| LXD-1000 | 1000 | 65-160 | 5.5 | 10.0 |
Benefits for Your Plastic Molding Process
Improved product quality: Dried resin reduces silver streaks, bubbles, and brittleness in finished parts, yielding higher pass rates.
Faster cycle times: Consistent moisture removal allows for higher injection speeds and shorter cooling periods, boosting productivity.
Lower scrap rates: Eliminating moisture-related defects cuts material waste by up to 15%.
Easy integration: Compact footprint and optional vacuum loader connect directly to molding machines; can be retrofitted into existing lines.
Reliable performance: Equipped with over-temperature protection, filter blockage alarm, and automatic shut-off for safe operation.
Long service life: All contact parts are stainless steel; desiccant regeneration cycle is fully automatic, minimizing maintenance.

Frequently Asked Questions
Q: What types of plastic materials can this dryer handle?
A: It is suitable for hygroscopic resins such as ABS, Nylon (PA), Polycarbonate (PC), PET, PBT, PMMA, and many engineering plastics. For non-hygroscopic materials like PP or PE, a standard hot air dryer is recommended instead.Q: How long does it take to dry the material?
A: Drying time depends on material type, initial moisture content, and temperature. Typically, 2-4 hours is sufficient for most engineering plastics. The PLC controller can be set accordingly.Q: Does the machine come with a material loader?
A: The standard model includes a manual loading hopper. An optional automatic vacuum loader or screw conveyor can be integrated for continuous feeding.Q: What is the dew point achieved by the dehumidifying system?
A: The twin-desiccant bed can achieve a dew point as low as -40°C, ensuring extremely low moisture content in the output air.Q: Can the drying temperature be adjusted for different materials?
A: Yes, the temperature range is 65°C-160°C, adjustable via the PID controller. The machine will automatically lower the temperature if set too high for safety.Q: Is the machine easy to maintain?
A: Yes. The hopper has a sight glass and drain valve for cleaning. The desiccant bed regenerates automatically; periodic replacement of filters and desiccant is recommended every 1-2 years depending on usage.Q: What are the power supply options?
A: Standard is 380V/50Hz 3-phase. Single-phase 220V or other voltage/frequency configurations can be customized upon request.Q: Do you provide installation and training?
A: We provide detailed manuals and video instructions. For overseas clients, we offer online remote support. On-site installation and training are available for large orders at additional cost.
