Overview
Plastic hopper dryer, as an upgraded version of traditional standard hot air dryers, is a high-efficiency and cost-effective model developed specifically for the drying needs of plastic raw materials.The plastic hopper dryer is mainly composed of a hopper, a drying barrel, a hot air diffusion device, a hot air pipe bending component, a digital display temperature control system, a low-noise fan, a return air filter device (optional), and an over-temperature trip protection device.This plastic drying equipment is equipped with a double-layer insulated barrel and a material viewing window design, ensuring the plastic material drying process is safe and controllable.It can effectively handle moist raw materials generated in links such as packaging, transportation, and recycling, and integrates environmental protection concepts through innovative design to provide stable and reliable drying solutions for the plastic industry.Its direct connection design facilitates installation on plastic molding machines, which is space-saving and features high drying efficiency. It has a wide range of applicable loading capacities to meet the production needs of enterprises of different scales.
Working Principle:
The plastic hopper dryer uses a drying fan to send high-temperature dry hot air (heated by an electric heating tube) into the drying barrel. The hot air is evenly dispersed into the raw materials through a protective screen and a hole screen, and continuous heating causes moisture in the raw materials to evaporate.The hot air carrying moisture is discharged through a cyclone exhaust system. The optional hot air recovery device can filter the exhaust air for recycling and reuse, forming a closed loop to reduce energy consumption (a key advantage of energy-saving plastic dryers).The entire process maintains a stable temperature through a precision temperature control system, achieving efficient dehumidification and drying of plastic raw materials.
Suitable Material Industries:
It is mainly applicable to the production and processing industries of plastic raw materials such as ABS, PC, PET, and nylon, including but not limited to the drying of raw materials (e.g., new materials, recycled materials, engineering plastic pellets) whose processing performance is affected by moisture.It is widely used in plastic molding production lines such as injection molding, blow molding, and extrusion, providing professional drying support for various plastic product manufacturers (a practical solution for plastic molding line dryers).
Application And Installation Methods:
The integrated design is particularly suitable for direct installation on injection molding machines for drying, which is fast and space-saving (optimal for small to medium-sized plastic molding workshops).The split-type design can be integrated with different types of floor stands and conveying functions, making it particularly suitable for large and vertical injection molding machines under factory height restrictions (meets the needs of large-scale plastic production plants).
Maintenance Precautions:
- Regular cleaning: Remove residual powder in the hopper to prevent blockage of hot air pipes (a key step in daily plastic dryer maintenance).
- Electric heating system inspection: Inspect electric heating tubes and circuits monthly to ensure no aging or poor contact (ensures the stability of the plastic dryer’s heating system).
- Lubrication maintenance: Add lubricating oil to fan bearings regularly to ensure smooth operation (extends the service life of the plastic dryer’s fan).
- Filter replacement: If equipped with an air intake filter, replace the filter element in a timely manner according to usage frequency (maintains the air quality of the plastic dryer’s hot air system).
- Avoid overloading: Feed materials strictly according to the rated capacity to prevent overloaded operation of the equipment (protects the plastic dryer from premature damage).
