Features
(1) Clean Production Environment
The internal chamber adopts stainless steel structure with full argon arc welding to reduce dust generation and improve cleanliness.
(2) Uniform Temperature Distribution
Special air circulation design ensures stable hot air flow and temperature uniformity throughout the tunnel.
(3) High Precision Temperature Control
Equipped with OMRON PID temperature control system and SSR solid-state relay for accurate heating control.
(4) Reliable Continuous Conveying System
The conveyor system provides smooth product transportation without vibration, jamming, scratches, or product damage.
(5) Surface Protection Design
The conveyor structure prevents product contamination, edge damage, and surface defects during transportation.
(6) Improved Product Yield
The drying process prevents bubbles, over-baking, yellowing, and white spots after heating.
(7) Energy Saving Insulation Design
128K high-density ceramic fiber insulation effectively reduces heat loss and improves energy efficiency.
(8) Clean Conveyor Design
The conveyor is supported by small rollers to reduce friction and particle generation.
(9) Dust Removal and Static Elimination System
The inlet is equipped with adhesive dust removal rollers, while the outlet includes an ionizing static eliminator to reduce electrostatic issues.
