Features
High Temperature Clean Processing
The oven uses SUS304 stainless steel for the inner chamber, providing excellent corrosion resistance and cleanliness performance for high-temperature production environments.
Stable Temperature Uniformity
The optimized airflow circulation structure ensures even heat distribution inside the tunnel, with temperature uniformity controlled within ±5℃.
Precision Temperature Control System
Equipped with OMRON PID temperature control technology and SSR solid-state relay output, the system provides accurate and stable temperature adjustment.
Low Particle Generation Design
The inner chamber is fully argon arc welded, and the conveyor mesh is supported by small rollers to reduce friction and particle generation.
Reliable Conveyor Performance
The PTFE conveyor belt features a smooth surface to prevent product scratches, edge damage, and contamination during transportation.
Efficient Heating Performance
Medium-wave quartz heating tubes provide fast heating response and stable drying results.
Product Quality Protection
The optimized drying process helps prevent product defects such as yellowing, white spots, bubbles, over-baking, scratches, and contamination.
Dust and Static Control
The inlet is equipped with a dust-removing roller to keep the conveyor clean, while the outlet can be equipped with a static elimination bar to reduce electrostatic issues.
Safe Operation System
Multiple safety functions including emergency stop, overload protection, phase protection, and over-temperature protection ensure safe equipment operation.
