Hopper Dryer: High-Efficiency Plastic Material Drying Solution for Stable Production
In plastic processing, the moisture content of raw materials directly affects product quality—moisture residues can cause defects like bubbles, cracks, or surface unevenness in injection molding, extrusion, or blow molding processes. The hopper dryer emerges as a critical pre-processing equipment, efficiently removing moisture from plastic pellets, granules, or powders to ensure stable material performance and flawless end products.
Core Advantage: Efficient Drying, Lay the Foundation for Quality
1. Rapid Moisture Removal with Uniform Heating
Equipped with a high-performance heating system and optimized air circulation design, the hopper dryer delivers consistent heat distribution throughout the material chamber. Whether processing hygroscopic materials like PA, PC, or PET, or common plastics such as PP and PE, it quickly evaporates moisture (with drying efficiency up to 99% for standard materials) and discharges humid air through a dedicated exhaust system, ensuring materials reach the ideal moisture content (typically ≤0.02%) required for processing.
2. Energy-Saving Design Reduces Operating Costs
Adopting intelligent temperature control and heat insulation technology, the dryer minimizes heat loss during operation. The insulated hopper body retains heat effectively, while the thermostat precisely maintains the set drying temperature (adjustable from 50℃ to 180℃) to avoid energy waste from overheating. Compared to traditional drying methods, it reduces energy consumption by 20-30%, lowering long-term production costs.
Technical Highlights: Smart & Reliable for Hassle-Free Operation
1. User-Friendly Intelligent Control
Featuring a digital display panel, operators can easily set drying temperature, time, and airflow. The system automatically monitors and maintains parameters, with built-in alarms for abnormal temperatures or motor failures, ensuring safe and stable operation. Some models support timed startup/shutdown, allowing pre-drying to match production schedules and improve workflow efficiency.
2. Durable Structure for Long-Term Use
The hopper is made of high-quality stainless steel, resistant to corrosion and high temperatures, ensuring easy cleaning and preventing material contamination. The robust motor and fan assembly provide strong airflow, with low noise operation (≤65dB) to maintain a comfortable workshop environment. Available in various capacities (from 10kg to 500kg) to suit small-scale labs, medium-sized production lines, or large factories.
Wide Application: Essential for Multiple Plastic Processing Scenarios
- Injection Molding: Dries plastic pellets before injection to prevent bubbles in finished products (e.g., automotive parts, electronic enclosures).
- Extrusion: Ensures uniform moisture content in raw materials for film, sheet, or profile extrusion, avoiding surface defects.
- Blow Molding: Prepares moisture-sensitive materials like PET for bottle blowing, ensuring bottle transparency and structural strength.
- 3D Printing: Dries filament materials to improve printing precision and reduce layer adhesion issues.
