Description

Technical Field

[0001] The utility model relates to the technical field of corn oil production, in particular to a system for preparing corn oil rich in linolenic acid. Background Art

[0002] Linolenic acid, scientific name: cis-9, cis-12, cis-15-octadecatrienoic acid, is an ω-3 fatty acid containing three double bonds. It usually exists in dark green plants in the form of glycerides. It is the main component of human tissue cells and one of the essential fatty acids for the human body. Taking linolenic acid can play a role in health care, such as lowering blood lipids, preventing thrombosis, and regulating prostaglandin precursors. It has been widely used in the preparation of health products and pharmaceuticals.

[0003] Elderberry is a member of the genus Sambucus in the family Caprifoliaceae. It is sweet, bitter and flat in nature and flavor. It has the effects of setting bones and tendons, promoting blood circulation and relieving pain, and removing wind and dampness. Its fruit has a high oil content and a high content of α-linolenic acid. Flaxseed is the mature seed of flax, which is also the main source of α-linolenic acid. Flax oil made from elderberry fruit or flaxseed has certain effects on anti-inflammation, anti-thrombosis and lowering blood lipids. However, due to the dark color and special smell of flax oil, consumers have low acceptance.

[0004] Based on this, flax oil can be mixed with other oils to give the oils higher nutritional value by utilizing the linolenic acid that flax oil is rich in. Utility Model Content

[0005] In view of the technical problems that linseed oil has a dark color, a special taste and a low degree of consumer acceptance, the utility model provides a system for preparing corn oil rich in linseed acid, which mixes linseed oil with corn oil to add linseed acid to the corn oil, and at the same time utilizes the secondary refining and the light color and no peculiar smell of corn oil to reduce the influence of the dark color and strong taste of linseed oil.

[0006] The technical solution of this utility model is as follows:

[0007] A system for preparing corn oil rich in linolenic acid comprises a linseed oil pressing system, a corn oil pressing system and a linseed oil / corn oil mixing system. The linseed oil pressing system comprises a heater A, a crusher A, an oil press A, a refining unit A and an oil storage tank A which are connected in sequence. The corn oil pressing system comprises a heater B, a crusher B, an oil press B and an oil storage tank B which are connected in sequence. The linseed oil / corn oil mixing system comprises a mixing tank C, a refining unit C, a detoxification device C and an oil storage tank C which are connected in sequence. The oil storage tank A and the oil storage tank B are respectively connected to the mixing tank C.

[0008] Furthermore, a flaking machine A is provided between the crusher A and the oil press A, and a flaking machine B is provided between the crusher B and the oil press B. By providing the flaking machine A and the flaking machine B, the processing amount and oil yield of flaxseed and corn can be increased.

[0009] Furthermore, the refining unit A includes an alkali refining tank A, a bleaching tower A, a dewaxing tank A and a deodorizing tank A which are connected in sequence.

[0010] Furthermore, the refining unit C includes an alkali refining tank C, a bleaching tower C, a dewaxing tank C and a deodorizing tank C which are connected in sequence.

[0011] Furthermore, the detoxification device C includes a detoxification tank, an ozone pipe is provided on the detoxification tank, and the other end of the ozone pipe is connected to the ozone generator. Ozone detoxification after mixing linseed oil and corn oil can effectively degrade aflatoxin in the oil products and ensure the edible safety of the oil products.

[0012] Furthermore, a stirring rod is provided inside the detoxification tank, which can enhance the contact between the oil and ozone through stirring, making the detoxification more thorough.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a system for preparing corn oil rich in linolenic acid. The system can prepare linseed oil and corn oil respectively and then mix the two oils. First, the linseed oil is refined separately, and then the mixed oil product of the linseed oil and corn oil is refined once, so the color and smell of the linseed oil can be more fully removed; and the edible safety of the oil is guaranteed by setting a detoxification system.
