해결 방법
Establish drying batch records: temperature, time, loading amount, dew point, moisture content sampling recorded item by item and linked to production batch numbers; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability

Drying records are the first link of the traceability system and must be institutionalized; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
