PA6 Drying Energy Consumption Optimization
Problem Phenomenon
The drying system runs continuously for 24 hours with high energy consumption, but shutting it down is feared to affect production
Cause Analysis
The dryer runs continuously at maximum load, a large amount of dry air is wasted when actual production fluctuates; poor insulation and pipeline air leakage further increase energy consumption; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Run the dryer in time-sharing according to the production plan, add an insulation layer to the hopper to reduce heat loss; check pipeline sealing; centrally supply drying air to multiple machines to improve equipment utilization; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Drying energy consumption optimization relies on on-demand operation and insulation sealing, without affecting drying quality; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
