The drying process of camellia seed oil is divided into three stages:

1. During the preheating stage, set the temperature to 50 degrees Celsius, for a duration of 2 hours. Use the drying mode without dehumidification to ensure even heating of the camellia seeds both inside and out.

2. During the constant-speed drying phase, increase the temperature to 60 degrees, activate the drying and moisture-removal mode, for a duration of 10 hours, and set the relative humidity to 30%.

3. During the deceleration drying phase, set the temperature to 65 degrees, continue with the drying + moisture extraction mode for 8 hours, and set the relative humidity to 15%.
