Deqing Leixin Coating Equipment Co., Ltd., established in 2011 and headquartered in Huzhou, Zhejiang, China, is a professional manufacturer specializing in industrial drying and coating solutions. With a factory area of 1,000–3,000 square meters and an annual export value of US$1–1.5 million, we serve clients across North America, South America, Europe, Southeast Asia, Africa, and more. Our Energy-Saving Plastic Product Drying Line with Frequency Inverter and Overheat Protection, PLC represents the pinnacle of efficiency and reliability for plastic processing industries. Designed to reduce energy consumption by up to 30% compared to conventional dryers, this drying line integrates advanced inverter technology, precise PLC control, and comprehensive safety features to ensure consistent, high-quality drying of plastic pellets, granules, and recycled materials. Whether you are a compounder, injection molder, or extruder, this system offers the perfect balance of performance, durability, and cost-effectiveness.
Product Features & Technical Specifications
Our drying line is engineered to meet the demanding needs of modern plastic production. Below are the key features and benefits:
- Energy-Saving Frequency Inverter: The variable frequency drive automatically adjusts motor speed based on real-time load requirements, reducing power consumption by 25–35% without compromising drying performance. This results in lower operating costs and a smaller carbon footprint.
- PLC Intelligent Control System: A user-friendly touch screen interface allows operators to set drying temperature, time, and airflow parameters with precision. The PLC stores up to 50 recipes for different materials, ensuring repeatable quality and minimal manual intervention.
- Overheat Protection & Safety Alarms: Multi-level thermal sensors monitor internal temperature. If overheating occurs, the system automatically shuts down the heating elements and triggers an audible/visual alarm, preventing fire hazards and equipment damage.
- High-Efficiency Insulation: The drying chamber is lined with 50 mm thick rock wool insulation, minimizing heat loss and maintaining stable temperatures even in fluctuating ambient conditions.
- Modular Design: The line can be configured with multiple drying hoppers and a central air distribution unit to handle various throughput capacities (from 200 kg/h to 2000 kg/h). Expansion is easy as production scales.
- Corrosion-Resistant Construction: The main structure is made of stainless steel (SUS304) with a powder-coated finish, ensuring long service life in harsh industrial environments.

Frequently Asked Questions (FAQ)
-
Q: What materials can this drying line handle?
A: It is suitable for drying plastic pellets, granules, regrind, and recycled materials such as PP, PE, ABS, PC, PA, PET, and more. The adjustable temperature range (up to 160°C) covers most drying requirements for hygroscopic polymers. For materials needing higher temperatures, please consult our engineering team for a customized solution. -
Q: How does the frequency inverter save energy compared to a standard dryer?
A: The inverter controls the fan motor speed based on the actual air demand of the drying process. When less airflow is needed (e.g., during idle or low load), the motor runs slower, consuming less power. Typical savings are 25–35% compared to fixed-speed fans. The precise airflow adjustment also improves drying uniformity. -
Q: Is the PLC easy to operate for workers with minimal technical training?
A: Yes. The touch screen interface has a clear menu structure with icons and prompts in multiple languages. Pre-loaded recipes for common materials allow one-button startup. We provide a detailed operation manual and free online training sessions for your staff. The system also includes a manual override option for emergency situations. -
Q: What safety features are included beyond overheat protection?
A: In addition to overheat shutdown, the system has motor overload protection, phase loss protection, emergency stop button, and a door interlock that stops the fan if the chamber door is opened. All electrical components are IP54 rated for dust and splash resistance. -
Q: What is the lead time and shipping options?
A: Standard models (with capacities up to 1000 kg/h) are typically shipped within 30–45 working days after order confirmation. For custom configurations, lead time may be 45–60 days. We ship FOB from Ningbo or Shanghai. We can also arrange CIF delivery to your port. Sea freight, air freight, or express courier are available upon request. -
Q: Does the drying line come with a warranty? What about after-sales support?
A: Yes, we offer a 12-month warranty covering manufacturing defects in materials and workmanship. After-sales support includes lifetime remote technical assistance (via email, phone, or video call), spare parts supply, and optional on-site service at cost. We maintain an inventory of common spare parts for quick dispatch. -
Q: Can the drying line be integrated with existing conveying systems or extruders?
A: Absolutely. We design the system with standard flanges and communication interfaces (RS485 or Ethernet), allowing easy integration with your existing material handling equipment. Our engineers can customize the PLC program to synchronize with upstream or downstream machinery. Please provide your equipment specifications for integration analysis. -
Q: How do I know which capacity model suits my production volume?
A: Consider your hourly throughput of plastic material and the required moisture content. For example, if you process 500 kg/h of polycarbonate (which requires 4–5 hours drying at 120°C), you may need a hopper capacity of at least 2500 kg. Our technical sales team can help you calculate the optimal size based on your material, inlet moisture, and target moisture level. We can also recommend a dual-hopper system for continuous drying without interruptions.
