In modern plastic manufacturing, consistent material quality and efficient production are inseparable from precision drying and feeding systems. Among all available solutions, the Dehumidifier Dryer and Feeding system stands out as a cornerstone of efficiency, stability, and energy savings. It not only ensures that plastic granules remain moisture-free but also streamlines material conveying throughout the entire process. As a manufacturer deeply involved in plastic machinery innovation, Ningbo Sinburller Intelligent Machinery Manufacturing Co., Ltd. has developed a range of Dehumidifier Dryer and Feeding systems that cater to various production scales, guaranteeing reliability, precision, and sustainability.
A Dehumidifier Dryer and Feeding system is an integrated unit that combines three major functions—dehumidifying, drying, and material conveying. Its main role is to remove moisture from hygroscopic plastic materials such as PET, PC, PA, and ABS before processing, thereby preventing defects like bubbles, silver streaks, or brittleness in finished products.
In addition to drying, the system automatically feeds the material into the molding or extrusion machine, creating a fully closed-loop operation that prevents secondary moisture absorption and contamination. This not only enhances product quality but also improves production efficiency and consistency.
The working principle involves three key stages:
Dehumidification:
The system uses a honeycomb rotor or molecular sieve to absorb moisture from the air, producing ultra-low dew-point dry air (as low as -40°C).
Drying:
The dried air circulates through the hopper, removing absorbed moisture from plastic pellets while maintaining a consistent drying temperature.
Feeding:
The dry, clean material is conveyed through a sealed pipeline into the molding machine hopper, maintaining the material's dryness and purity until processing begins.
High Drying Efficiency: Reduces material moisture content effectively and quickly.
Energy Saving: Equipped with smart control systems to minimize power consumption.
Stable Dew Point Control: Maintains a constant low dew point to ensure drying consistency.
Closed-Loop Conveying: Prevents contamination and moisture reabsorption.
Easy Operation: Intelligent touch-screen interface with real-time monitoring.
Modular Design: Suitable for small, medium, and large-scale production needs.
| Model | Drying Capacity (kg/h) | Hopper Volume (L) | Dew Point (°C) | Heating Power (kW) | Air Flow (m³/h) | Feeding Distance (m) |

| SDF-25 | 25 | 50 | -40 | 2.5 | 40 | 5 |
| SDF-50 | 50 | 100 | -40 | 4.5 | 80 | 6 |
| SDF-100 | 100 | 200 | -40 | 6.5 | 120 | 8 |
| SDF-200 | 200 | 400 | -40 | 9.0 | 200 | 10 |
| SDF-400 | 400 | 800 | -40 | 12.0 | 320 | 12 |

Moisture is a hidden enemy in plastic processing. If not controlled, it can lead to serious production issues—such as poor surface finish, decreased mechanical strength, and unpredictable shrinkage.
The Dehumidifier Dryer and Feeding system ensures that each pellet is processed under optimal conditions. By maintaining the material's moisture at a stable and minimal level, it enhances mechanical properties, transparency, and overall finish quality of the final product.
Injection Molding: For precise parts like optical lenses, automotive components, and medical devices.
Extrusion: For pipes, profiles, and sheets where surface quality and stability are crucial.
Blow Molding: For bottles and containers made from PET or PC.
Engineering Plastics: For materials like PA, PBT, PC, and ABS that easily absorb moisture.
Q1: What materials can be processed with the Dehumidifier Dryer and Feeding system?
A1: It is suitable for a wide range of hygroscopic materials including PET, PC, PA, PMMA, and ABS. Each model can be adjusted to meet the specific drying requirements of different plastics.
Q2: How long does it take for the Dehumidifier Dryer and Feeding system to dry materials completely?
A2: The drying time typically ranges from 2 to 4 hours depending on the material type and moisture content. The system's intelligent temperature control ensures consistent drying results.
Q3: Can the Dehumidifier Dryer and Feeding system be integrated with an existing injection molding machine?
A3: Yes. Our systems are designed for flexible integration and can be easily connected with most injection molding or extrusion machines through a modular interface.
Q4: What maintenance is required for optimal performance?
A4: Regular cleaning of filters, inspection of air ducts, and rotor maintenance every 6–12 months ensure long-term stability and high performance. The control panel provides real-time alerts for scheduled maintenance.
