TPU Drying Energy Consumption
Problem Phenomenon
TPU drying time is long and energy consumption is high
Cause Analysis
The low-temperature long-time drying route accumulates energy consumption; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solution
Optimize time according to hardness grading; dryer heat recovery; run on demand; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Drying energy consumption is optimized by grading; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
