PESU Oven Drying
Problem Phenomenon
PESU air-circulation oven drying, uniformity and efficiency.
Cause Analysis
PESU air-circulation oven or dehumidifying hopper drying; oven uniformity; material layer thickness; time and temperature; energy efficiency.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Oven uniformity management; ②material layer thickness control; ③time and temperature specifications; ④energy optimization; ⑤effect verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU oven drying is the standard method; uniformity is the key to quality; specifications ensure effectiveness.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
