Separate two tasks
Treat dewatering and drying as separate duties. Describe the incoming condition, preparation route and downstream feed requirements instead of requesting simply “as dry as possible”.
Discuss preparation and extrusion together
Discuss extrusion degassing together with feed preparation. Ask the supplier to confirm acceptable incoming conditions rather than treating a vent as a substitute for all preparation.
Agree how moisture is checked
Agree sampling point, timing, measurement method and target conditions. Results from different methods may not be comparable; do not assume a fixed residual moisture level without supporting trials.
