Embodiment 1
[0027] Embodiment one: see attached figure 1 , 4 , a kind of extraction process of perilla essential oil, comprises the following steps:
[0028] (1) Clean the broken wall: Put the perilla stem and seeds into the ultrasonic cleaning machine to clean the broken wall, the ultrasonic frequency is 20KHz, and the time is 10min;
[0029] (2) Freeze-drying: After the wall is broken, the raw materials are put into the quick-freezing tunnel to freeze, the freezing temperature is -20°C, and the freezing time is 6 hours; enter the vacuum drying chamber, and when the vacuum degree is 60Pa, start the heating programmer and set the drying curve of the heating programmer : 1. 20°C uniformly rises to 100°C for 45 minutes; 2. 100°C maintains for 360 minutes; 3. 100°C uniformly drops to 65°C for 210 minutes; 4. 65°C uniformly drops to 60°C for 150 minutes; 5. Keep at 60°C for 300 minutes;
