• Simple monitoring based only on dryer internal or exhaust temperature
• Risk judgment of carbonization (overheating, ignition) relying on worker experience
• Limitations in detecting subtle anomalies using temperature changes alone
• Restricted real-time detection of gas emissions such as CO and CO2
• High accident rate due to failure in early detection
• Quality degradation and safety incidents linked to production
• Real-time detection based on multiple sensors
• Early warning and immediate response upon real-time sensor risk signal detection
• Rapid detection of carbonization to prevent fire and quality incidents
• Minimizing equipment downtime and production loss
• Risk assessment using clear numeric criteria such as temperature variation and CO/CO2 concentration
• Minimizing judgment variability among workers and human errors
• Risk prediction and preventive maintenance based on AI and big data analysis
