Problems solved by technology

However, the existing seal oil with OMEGA-3 unsaturated fatty acid content level still contains more non-medicinal ingredients such as saturated fatty acids, resulting in weakened or incomplete medicinal effects. Therefore, the existing seal oil needs to be further refined

Embodiment 1

[0027] Refined seal oil: containing OMEGA3 polyunsaturated fatty acid DPA 8.31%, EPA 11.29%, DHA 18.12% (weight percentage), the sum of the three is 37.72%.

[0028] This refining seal oil is made by following method:

[0029] Equipment: German VTA short-range molecular distillation apparatus with a distillation area of ​​0.4m 2 .

[0030] Raw materials: crude seal oil, the sum of DPA, EPA, and DHA is 16.84%, provided by Tianjin Tasly Modern Chinese Medicine Resources Co., Ltd.

[0031] Operating conditions: two-stage vacuum distillation is adopted, the pressure of the first polar molecular still is 5Pa, the evaporation temperature is 140°C, and the speed of the wiped film rotor is 100rpm; the pressure of the second polar molecular still is 0.3Pa, and the evaporation temperature is 300°C. The speed of the wiped film rotor was 250 rpm; the feed rate was 7 kg / hour. The seal oil crude oil passes through the wiped film evaporator, the low boiling point components are evaporated...

Embodiment 2

[0033] Refined seal oil: containing OMEGA3 polyunsaturated fatty acid DPA 6.56%, EPA 8.21%, DHA 16.32% (percentage by weight), the sum of the three is 31.09%.

[0034] This refining seal oil is made by following method:

[0035] Equipment: same as embodiment one.

[0036] Raw material: with embodiment one.

[0037] Operating conditions: two-stage vacuum distillation is adopted, the pressure of the first polar molecular still is 10Pa, the evaporation temperature is 130°C, and the rotating speed of the wiped film rotor is 100rpm; the pressure of the second polar molecular still is 0.5Pa, and the evaporation temperature is 25°C. The speed of the wiped film rotor was 250 rpm; the feed rate was 10 kg / hour. The seal oil crude oil passes through the wiped film evaporator, the low boiling point components are evaporated, and the heavy oil phase components that have not been evaporated are collected to obtain refined seal oil.

Embodiment 3

[0039] Refined seal oil: containing OMEGA3 polyunsaturated fatty acid DPA 9.44%, EPA 12.52%, DHA 19.46% (percentage by weight), the sum of the three is 41.42%.

[0040] This refining seal oil is made by following method:

[0041] Equipment: same as embodiment one.

[0042] Raw material: with embodiment one.

[0043]Operating conditions: two-stage vacuum distillation is adopted, the pressure of the first polar molecular still is 2Pa, the evaporation temperature is 150°C, and the speed of the wiped film rotor is 100rpm; the pressure of the second polar molecular still is 0.2Pa, and the evaporation temperature is 300°C. The speed of the wiped film rotor was 250 rpm; the feed rate was 6 kg / hour. The seal oil crude oil passes through the wiped film evaporator, the low boiling point components are evaporated, and the heavy oil phase components that have not been evaporated are collected to obtain refined seal oil.

Abstract

The invention relates to refined fur seal oil which is abundant with OMEGA-3 unsaturated fatty acid. Wherein, it comprises 20-60% DPA, EPA and DHA; it is made from original fur seal oil by molecule distill method and multistage distill, while the pressure of first molecule distiller is 0.01-20Pa; the pressure of second molecule distiller is 0.05-1Pa, and the material feeding speed is 1-20kg / h, the vaporizing temperature is 50-400Deg. C, the rotation speed of scrap film rotor is 100-350rpm. The invention has high content of effective components.

Description

[technical field] [0001] The invention belongs to the technical field of medicines, in particular to a refined seal oil rich in OMEGA-3 polyunsaturated fatty acids. [Background technique] [0002] Fur seal is a common name for the harp seal (Harp seal), which lives in the Arctic and the northern part of the Atlantic Ocean. Due to conservation measures taken by the Canadian government, fur seal populations are growing steadily at a rate of 5% per year. In order to maintain the ecological balance between fur seals and fish schools, with the approval of the United Nations and the Canadian government, a small amount of fur seals can be killed every year. [0003] Seal oil is rich in OMEGA-3 unsaturated fatty acids needed by the human body, and its main active ingredients are eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and eicosapentaenoic acid (DPA) Docosahexaenoic acid (DHA) has the functions of reducing the content of triglyceride and total cholesterol, lowering...
