Description

Technical Field

[0001] The present invention relates to the technical field of oil extraction facilities, and particularly to a device for extracting peony seed oil from peony seeds. Background Art

[0002] Peony seed oil, also known as peony oil, is a woody nut vegetable oil extracted from peony seeds. Peony seed oil is not only rich in nutrition, but its unique biological activity and physiological effects have been confirmed by the international medical community and the nutrition community. These components can not only promote the development of optic nerve cells and the formation of brain nerve cells, and have peculiar effects such as anti-aging, prolonging life, and activating peripheral nerves. It has preventive and improving effects on cardiovascular and cerebrovascular diseases, reducing blood lipid, reducing blood pressure, cancer prevention and anti-cancer, anti-radiation, protecting eyesight, enhancing intelligence, etc. It can also eliminate pigment spots, reduce wrinkles, make the skin delicate, smooth and elastic. Especially, it has a great impact on the eyesight, brain and body development of fetuses and infants, which is incomparable with ordinary edible oils; in the production process, peony seed oil is made from peony seed kernels through processes such as pressing (or subcritical biotechnology), crude oil filtration, decolorization, deodorization, dewaxing, and precision filtration.

[0003] Because during the process of refining peony seed oil, a large amount of oil residue is carried in the peony seed oil obtained after grinding and pressing the peony seeds, and filtration is required. Usually, a filter screen is used for filtration. However, due to the adhesive effect of the oil residue itself, the oil residue is easily adhered to the filter screen during the filtration process, and the filter holes on the filter screen are blocked by the oil residue, resulting in a decrease in the passing rate of the filter screen. Moreover, the peony seed oil is mixed with the oil residue precipitate, and the static leakage time is long, which will affect the filtration efficiency of the peony seed oil. At this time, the filter screen needs to be cleaned or replaced, and such operations are cumbersome, which is not conducive to the processing efficiency of peony seed oil and also increases the production cost. Summary of the Invention

[0004] In order to make up for the defects of the prior art, the present invention provides a device for extracting peony seed oil from peony seeds with high filtration efficiency.

[0005] The present invention is realized by the following technical solutions: An apparatus for extracting peony seed oil from peony seeds, comprising a filtration tank.

[0030] The included angles between the primary scraper 15 and the primary brush 16, and between the secondary scraper 23 and the secondary brush 24 are preferably not more than 10°.

[0031] The primary scraper 15 and the secondary scraper 23 can also be set in a spiral shape.

[0032] The working process is as follows: Start the motor 4 and the cylinder 9. The well-pressed peony seed oil enters the tank body 1 from the oil inlet 2, is filtered by the primary filter screen 13 and the secondary filter screen 21, and finally flows out from the oil outlet 3. During this process, the rotary drum 6 drives the primary scraper 15, the primary brush 16, the secondary scraper 23, and the secondary brush 24 to rotate, respectively scraping and brushing the solid substances or viscous substances adhering to the primary filter screen 13 and the secondary filter screen 21. The solid substances or viscous substances flow into the primary sedimentation tank 12 and the secondary sedimentation tank 18 respectively. At the same time, the cylinder 9 drives the primary filter screen 13 and the secondary filter screen 21 to move up and down through the frame 10 and the rotary drum 6. During the downward movement, the filtered peony seed oil below the primary filter screen 13 and the secondary filter screen 21 returns through the filter holes to backwash the mesh holes of the primary filter screen 13 and the secondary filter screen 21, and the blockages can be washed back, thereby avoiding the blockage of the mesh holes by the blockages. This can extend the service life of the primary filter screen 13 and the secondary filter screen 21, improve the filtration efficiency, and save manpower, material resources, and costs.
