How should hot-air temperature be validated against product moisture in a commercial food dryer?

Create a test matrix linking inlet moisture to target outlet moisture while recording hot-air temperature and airflow. For a fair comparison, keep raw material, batch size, speed, and environmental conditions consistent across suppliers. For export projects, confirm the utility conditions and installation requirements before the supplier starts final assembly. Any later change to the tested configuration should be documented and, when necessary, verified again before shipment. If the process is sensitive to raw-material variation, include defined material limits in the specification and acceptance protocol.
