[0002] Antarctic krill is a type of krill that lives in the Antarctic waters of the Southern Ocean. Antarctic krill contains krill oil, which can lower the levels of total cholesterol and triglycerides in serum. It has multiple functions such as lowering blood lipids, anti-aging, and anti-oxidation, and has high medicinal value in lowering blood lipids and preventing diseases such as coronary heart disease and atherosclerosis.

[0003] Currently, oil is extracted from Antarctic krill using extraction tubes. The remaining solid residue is then processed to obtain defatted krill powder, which can be used as animal feed. However, the extract often contains a small amount of solid residue, which needs to be filtered out before concentration and purification to improve the purity of the krill oil. After a period of filtration, the filter is prone to clogging. Existing systems typically require manual cleaning periodically, which is inefficient, prevents continuous production, and the removed residue is not effectively utilized.

[0004] In view of the problems existing in the prior art, this utility model combines years of design and use experience in related fields to design and manufacture a high-efficiency production system for Antarctic krill oil to overcome the above defects. Summary of the Invention

Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1-2 As shown, a high-efficiency production system for Antarctic krill oil includes an extraction tube 1 for mixing and extracting Antarctic krill powder with an organic solvent to obtain a first extract and solid residue powder. The extraction tube 1 has a liquid outlet, which is connected to a first storage tank 2. During cleaning of the filter tank 3, the first storage tank 2 temporarily stores the first extract. After cleaning, the first extract is added back into the filter tank 3 to achieve continuous production. The first storage tank 2 is connected to the filter tank 3. Because the first extract contains a small amount of residue, direct concentration and purification would affect the purity of the Antarctic krill oil. Therefore, the residue is filtered out using the filter tank 3 to obtain a second extract. The filter tank 3 has a first outlet 19 at its upper end, which is connected to a second storage tank 5 via a first pipe 4. The second storage tank 5 is connected to a purification system 6. The second storage tank 5 can temporarily store the second extract. The purification system 6 is a conventional device in the art, used to concentrate and purify the second extract to finally obtain Antarctic krill oil, which will not be described in detail here.

[0022] A three-way valve 10 is installed on the first pipe 4, and a discharge port is provided at the bottom of the second storage tank 5. One port of the three-way valve 10 is connected to the discharge port through a backflushing pipe 11. A liquid outlet 13 is provided at the bottom of the filter tank 3, and the liquid outlet 13 is connected to the extraction pipe 1 through the second pipe 12. In this invention, when the filter tank 3 becomes clogged, the second extract can be added to the filter tank 3 through the backflushing pipe 11 to flush down the residue in the filter tank 3 and return it to the extraction pipe 1. The residue and the solid powder in the extraction pipe 1 can be used together to produce defatted Antarctic krill powder, thus achieving recycling and improving cleaning efficiency. Both the backflushing pipe 11 and the second pipe 12 are equipped with a conveying pump and a conveying valve. The conveying pump is used to convey materials.

[0023] In this invention, the filter tank 3 is provided with an exhaust port, and an air vent valve 14 is provided on the exhaust port to facilitate the venting at the beginning of the filtration process. Preferably, the exhaust valve is located at the top of the filter tank 3. A filter element disc 15 is provided on the upper part of the filter tank 3. The filter element disc 15 is horizontally positioned, and its outer edge abuts against the inner wall of the filter tank 3. The filter element disc 15 has several filter holes 16, and filter bags 17 are fixedly connected to the side walls of the filter holes 16. A support basket 18 is provided on the filter bags 17. The first extract enters from below the filter element disc 15 and is filtered by the filter bags 17. The first storage tank 2 is connected to the filter tank 3 through a third pipe 7, and the connection end of the third pipe 7 to the filter tank 3 is located below the filter element disc 15. The filter element disc 15 is also provided with a second liquid outlet 20, and the first liquid outlet 19 is located below the filter element disc 15. The second liquid outlet 20 and the first liquid outlet 19 are connected by a liquid outlet pipe 21. The first pipe 4 is connected to the filter tank 3 through the liquid outlet pipe 21 on the first liquid outlet 19, and the filtrate leaves the filter tank 3 from the liquid outlet pipe 21. Multiple filter bags 17 are provided to increase the filtration area.

[0024] It should be noted that each connecting pipe between the devices in this invention is equipped with a delivery pump and a switching valve. The backflushing process of filter tank 3 is carried out under normal pressure, preferably every two hours, with a liquid flow rate of 3 m / s during backflushing. 3 / h, backflushing for 5 minutes. Preferably, the first liquid storage tank 2 and the second liquid storage tank 5 are equipped with level columns. The height of the level columns can also be observed to determine if the filter tank 3 is clogged, allowing for timely backflushing.

[0025] In this invention, the filter bag 17 is preferably made of polytetrafluoroethylene (PTFE). The extraction tube 1 is a countercurrent extraction tube, employing countercurrent extraction to increase the extraction efficiency of the first extract. The extraction tube 1 has a solid discharge port, which is connected to a material elevator (not shown in the figure). The material elevator is preferably a screw conveyor for conveying the solid residue powder. The material elevator is connected to a squeeze dryer 8, which compresses the solid residue powder to reduce the amount of organic solvent. The squeeze dryer 8 has a third liquid discharge port, which is connected to the extraction tube 1 to recover the organic solvent back into the extraction tube 1. The solid discharge end of the squeeze dryer 8 is connected to a dryer 9, which dries the solid residue powder to obtain defatted Antarctic krill powder.

[0026] Detailed operation process Antarctic krill powder and 95% ethanol are added to extraction tube 1 for countercurrent extraction to obtain a first extract and solid residue powder. The solid residue powder is conveyed by a screw conveyor to a squeeze dryer 8 for extrusion and solvent removal, and then sent to a dryer 9 for drying to obtain defatted Antarctic krill powder. The first extract enters a filter tank 3 through a first storage tank 2. The first extract rises along the inner wall of the filter tank 3, and after the residual residue is filtered out by the filter bag 17, it passes through the filter holes 16 and leaves the filter tank 3 from the outlet pipe 21, entering a second storage tank 5. From the second storage tank 5, it enters a purification system 6 for concentration and purification to obtain Antarctic krill oil. When the filter tank 3 needs to be flushed, close the switch valve and the transfer pump on the third pipeline 7, and temporarily store the first extract in the first storage tank 2. Close the connection between the first pipeline 4 and the second storage tank 5 on the three-way valve 10, open the connection between the backflushing pipeline 11 on the three-way valve 10 and the filter tank 3, start the transfer pump, backflushing the second extract into the filter tank 3 to wash off the filter bag 17 and the residue adhering to the tank wall. Open the valve of the material outlet 13 at the bottom of the filter tank 3 to transport the residue and the second extract together to the extraction pipe 1 for recycling.

[0027] After rinsing, close the connection between the backflushing pipe 11 on the three-way valve 10 and the filter tank 3, open the connection between the first pipe 4 and the second storage tank 5 on the three-way valve 10, close the valve of the material outlet 13 at the bottom of the filter tank 3, open the switch valve and the delivery pump on the third pipe 7, and the filter tank 3 continues to filter the first extract.
