1. If the heating temperature is invariable, raising the vacuum degree will improve the drying velocity;
2. If the vacuum degree is invariable, raising the heating temperature will improve the drying velocity;
3. If not only raising the vacuum degree but also the heating temperature, it will greatly improve the drying velocity.
