Embodiment 1
[0044] Embodiment 1: Chinese toon leaf prickly ash essential oil:
[0045] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 25%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 4000g / h, a screw speed of 300r / min, and an extrusion temperature of 100°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 10%. Take 100g of Zanthoxylum bungeanum powder and add it to 300mL of deionized water, stir evenly and seal the film. At a frequency of 50KHz and a density of 0.65W / cm 2 1. Ultrasonic extraction at a temperature of 55° C. for 60 minutes, then adding 7 mg of NaCl to the mixture, and distilling for 6 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.
Embodiment 2
[0046] Embodiment 2: Chinese toon leaf prickly ash essential oil:
[0047] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 20%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 2000g / h, a screw speed of 450r / min, and an extrusion temperature of 105°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 5%. Take 100g of Zanthoxylum bungeanum powder and add it to 350mL of deionized water, stir evenly and seal the film. At a frequency of 45KHz and a density of 0.6W / cm 2 1. Ultrasonic extraction for 45 minutes at a temperature of 58° C., then adding 7 mg of NaCl to the mixture, and distilling for 8 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.
Embodiment 3
[0048] Embodiment 3: Chinese toon leaf prickly ash essential oil:
[0049] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 22%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 3500g / h, a screw speed of 420r / min, and an extrusion temperature of 110°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 8%. Take 100g of Zanthoxylum bungeanum leaf powder and add it to 300mL of deionized water, stir evenly and seal the film. At a frequency of 80KHz and a density of 0.8W / cm 2 1. Ultrasonic extraction for 30 minutes at a temperature of 60° C., then adding 7 mg of NaCl to the mixture, and distilling for 8 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.
