Embodiment 1
[0026] The oil extraction method of perilla seed is:
[0027] ①Perilla seeds were pressed at 30°C to extract 20% of perilla seed oil to obtain perilla seed meal, and the oil content in the perilla seed meal was controlled at 30%.
[0028] ②Use a pulverizer to pulverize the perilla seed meal to a fineness of 10 mesh to obtain the perilla seed meal powder;
[0029] ③ Evenly mix 300g perilla seed meal powder and filler into the material bucket. The volume ratio of perilla seed meal powder to filler is 1:1. The filler is CS-E-3 made of stainless steel. Put the material bucket into the super Critical CO 2 In the extraction kettle of the equipment, open the intake valve of the extraction kettle, and use a booster pump to pump the CO 2 Pour into the extraction kettle continuously, the temperature of the extraction kettle is 35°C, and the pressure is 15MPa, so that the perilla seed oil is dissolved in supercritical CO 2 In the fluid, perilla seed oil was extracted after 10 minutes;...
Embodiment 2
[0033] The oil extraction method of perilla seed is:
[0034] ①Perilla seeds were pressed at 40°C to extract 25% perilla seed oil to obtain perilla seed meal, and the oil content in the perilla seed meal was controlled at 25%.
[0035] ② pulverize the perilla seed meal with a pulverizer, and the crushing fineness is 20 mesh, and obtain the perilla seed meal powder;
[0036] ③ Evenly mix 300g perilla seed meal powder and filler into the material barrel, put the material barrel into supercritical CO 2 In the extraction kettle of the equipment, the volume ratio of perilla seed meal powder to filler is 1:1.5, and the filler is made of stainless steel CS-E-8. Open the intake valve of the extraction kettle, and use a booster pump to pump CO 2 Pour into the extraction kettle continuously, the temperature of the extraction kettle is 40°C, and the pressure is 23MPa, so that the perilla seed oil is dissolved in supercritical CO 2 In the fluid, perilla seed oil was extracted after 10 m...
Embodiment 3
[0040] The oil extraction method of perilla seed is:
[0041] ① After the perilla seeds are mechanically cold-rolled at 45°C at low temperature, 30% of the perilla seed oil is squeezed out, and the perilla seed meal is obtained, and the oil content in the perilla seed meal is controlled at 20%.
[0042] ② pulverize the perilla seed meal with a pulverizer, and the crushing fineness is 20 mesh, and obtain the perilla seed meal powder;
[0043] ③ Evenly mix 300g perilla seed meal powder and filler into the material barrel, the volume ratio of perilla seed meal powder to filler is 1:2, the filler is CS-E-10, put the material barrel into supercritical CO 2 In the extraction kettle of the equipment, open the intake valve of the extraction kettle, and use a booster pump to pump CO 2 Pour into the extraction kettle continuously, the temperature of the extraction kettle is 45°C, and the pressure is 25MPa, so that the perilla seed oil is dissolved in supercritical CO 2 In the fluid, p...
