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...

Abstract

The invention provides a method for extracting oil from perilla seeds by a combined squeezing and supercritical CO2 extraction technology. According to the method, firstly, performing low-temperature squeezing on perilla seeds to obtain perilla seed oil and perilla seed meals, and controlling the oil content in the seed meals; secondly, pulverizing the seed meals, and mixing the pulverized seed meals with a filler; thirdly, further extracting residuary oil from the seed meals through a supercritical CO2 extraction technology, wherein the extraction rate of the perilla seed oil is 90.9-98.3%. In the method, the pretreatment squeezing process can solve the problems that materials are accumulated and caked and channeling is generated, so that the extraction rate of the oil is increased, and the method is suitable for industrial and large-scale production.

Description

technical field [0001] The invention relates to a method for extracting oil from perilla seeds, in particular to a method of pressing and supercritical CO 2 A method for extracting perilla seed oil. Background technique [0002] Perilla seed oil, obtained from the mature seeds of the medicinal plant perilla, is a highly unsaturated natural oil, the main component of which is α-linolenic acid, and its content is close to 50%. Perilla seed oil has the effects of protecting the liver, antithrombosis, lowering blood fat, lowering blood pressure, protecting eyesight, improving intelligence, anti-aging, and inhibiting allergic reactions and inflammation. [0003] The methods for industrially extracting perilla seed oil are mainly physical pressing and organic solvent extraction. The physical pressing method is a method of separating the oil from the raw material by mechanical pressure and refining the oil by physical means, but the oil yield of this method is low; the organic so...
