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

1. During the preheating phase, set the temperature to 50 degrees, for a duration of 2 hours. The drying mode should not remove moisture, ensuring even heating throughout the camellia seeds.

2. In the constant-speed drying stage, the temperature is raised to 60 degrees, activate the drying and dehumidification mode, for a duration of 10 hours, with a set relative humidity of 30%.

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