III. Operational Procedures and Maintenance

1. Operational Procedures
Preheating: Run the furnace unloaded to the set temperature (the first time you use the furnace, dry it to remove moisture).
Loading: Suspend the material on chains or fixtures to prevent accumulation that affects hot air circulation.
Operation: After starting the process, monitor the temperature curve and adjust the conveying speed to match process requirements.
Cooling: After the process ends, allow the furnace to cool naturally or activate the forced air cooling system.
2. Maintenance Points
Cleaning: Regularly clean the furnace chamber of any residue and check the lubrication of the chains.
Inspection: Quarterly calibrate the thermocouples and inspect the heating element connections and electrical wiring insulation.

IV. Safety and Design Advantages
1. Safety Design
Explosion-Proof Structure: Equipped with a pressure relief valve, explosion-proof door lock, and flame arrester, it is suitable for flammable and explosive working conditions.
Multiple Protections: Independent over-temperature protection, door open/shutdown sensor, and fault self-diagnosis. 2. Technical Advantages
Energy Saving and High Efficiency: Thermal cycle technology reduces energy consumption by over 30%, and the waste heat recovery system improves overall energy efficiency.
Automated Production: Supports continuous operation and pre-stores multiple sets of process parameters to meet flexible manufacturing needs.

Main structures and components:

I. Main Structure

1. Casing and Frame
Material: The casing is made of cold-rolled steel or 304 stainless steel, with a spray-coated or rust-proof finish for high-temperature corrosion resistance. The inner chamber is made of 1.5mm thick 304 stainless steel, meeting food-grade hygiene standards.
Furnace Design: A segmented, fully enclosed structure (single segment length up to 16.2 meters). The insulation layer is filled with ceramic fiber or high-density rock wool (thickness ≥ 100mm), achieving a heat dissipation rate of ≤5%.
2. Suspension Conveyor System
Chain and Track: Equipped with high-strength stainless steel chains or tracks with a spring tensioner, the conveying speed is adjustable (0.5–5m/min), accommodating materials of varying sizes.
Suspension Clamp: A high-temperature-resistant metal clamp or hook ensures stable suspension and even heating of the material.
