Embodiment 1
[0027] A kind of extraction process of perilla oil, comprises the following steps:
[0028] (1) The perilla leaves are crushed at a low temperature at -50°C, and the particle size after crushing is 30 mesh, and the perilla powder is obtained, wherein the moisture content of the perilla leaves is 7%;
[0029] (2) Put the perilla powder in the extraction kettle, add 2 times the weight of the extraction agent soybean oil, soak for 30 minutes, turn on the vacuum pump, wait until the pressure in the extraction kettle reaches -0.1Mpa, and use the pressure difference between the extraction kettle and the solvent tank to make it The solvent butane in the solvent tank is injected into the extraction kettle. Under the conditions of extraction temperature of 55°C and extraction pressure of 0.9MPa, after extraction for 8 hours, the extract enters the separation tank;
[0030] (3) The extract is separated in the separation tank at a temperature of 55 °C and a pressure of -0.1 MPa for 5 min...
Embodiment 2
[0034] A kind of extraction process of perilla oil, comprises the following steps:
[0035] (1) Perilla leaves were crushed at a low temperature at -70°C, the particle size after crushing was 40 mesh, and perilla powder was obtained, wherein the moisture content of perilla leaves was 9%;
[0036] (2) Put the perilla powder in the extraction kettle, add 3 times the weight of the extraction agent soybean oil, soak for 30 minutes, turn on the vacuum pump, wait until the pressure in the extraction kettle reaches -0.1Mpa, and use the pressure difference between the extraction kettle and the solvent tank to make it The solvent butane in the solvent tank is injected into the extraction kettle. Under the conditions of extraction temperature of 60°C and extraction pressure of 1.0MPa, after extraction for 7 hours, the extract enters the separation tank;
[0037] (3) The extract is separated in the separation tank at a temperature of 55 °C and a pressure of -0.1 MPa for 5 minutes. After ...
Embodiment 3
[0041] A kind of extraction process of perilla oil, comprises the following steps:
[0042] (1) Perilla leaves were crushed at a low temperature at -90°C, the particle size after crushing was 50 mesh, and perilla powder was obtained, wherein the moisture content of perilla leaves was 8%;
[0043] (2) Put the perilla powder in the extraction kettle, add 3 times the weight of the extraction agent, and the extraction agent is petroleum ether: ethanol: soybean oil in a weight ratio of 1:1:9, soak for 30 minutes, open Vacuum pump, when the pressure in the extraction kettle reaches -0.1Mpa, the solvent butane in the solvent tank is injected into the extraction kettle through the pressure difference between the extraction kettle and the solvent tank, and the extraction temperature is 65°C and the extraction pressure is 1.1MPa. After 5h, the extract enters into the separation tank;
[0044] (3) The extract is separated in the separation tank at a temperature of 55 °C and a pressure o...
