Description

Technical Field

[0001] This utility model relates to the field of aquatic product processing technology, and in particular to a fish oil extraction and processing equipment. Background Technology

[0002] Fish oil is a collective term for all oily substances found in fish, including body oil, liver oil, and brain oil. Fish oil, specifically, is an oil extracted from oily fish, rich in polyunsaturated fatty acids, and offers health benefits such as anti-inflammatory properties and lipid regulation. In a broader sense, fish oil refers both to fish oil preparations in capsule form and to the fat found in fish itself, with its main functional component being polyunsaturated fatty acids. Fish oil is widely used in various fields and is an indispensable part of people's lives.

[0003] A search revealed CN216236902U, entitled "A Fish Oil Extraction Device." This application addresses the issue that fish oil extraction requires pulverizing the fish first. Existing devices have poor pulverization effects, impacting extraction efficiency. Furthermore, frequent cleaning or replacement of the filter screen is often necessary to prevent clogging and maintain filtration efficiency. The improved device, by incorporating a chain, drive motor, drive wheel, driven wheel, telescopic rod, slide rod, scraper, and slag collection box, utilizes a chain to reciprocate the telescopic rod and scraper during filtration. The scraper effectively removes residue from the filter screen, preventing clogging and eliminating the need for manual cleaning. The scraped residue is easily collected and disposed of, resulting in superior performance.

[0004] Existing technologies have the following problems:

[0005] 1. The scraper needs to move back and forth to complete the cleaning work, which takes a long time, is not efficient, and has a relatively complex structure.

[0006] 2. The friction between the scraper and the filter screen is relatively large, resulting in greater wear and affecting the service life.

[0007] To address these shortcomings, we have proposed a fish oil extraction and processing equipment. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model adopts a screening mesh belt, a spray pipe and a back-blowing head. When extracting fish oil, fish meat can be put into a meat grinder to be crushed, and then conveyed to the fish oil extraction chamber by a screw conveyor for separation and extraction. Then, the oil suction device draws the fish oil into the separation box. The fish oil falls onto the top surface of the screening mesh belt, and the screening mesh belt screens and filters the fish oil. The fish oil passes through the screening mesh belt and falls into the oil receiving tank. Impurities continue to rotate with the screening mesh belt to the back-blowing head. The high-pressure air pump injects high-pressure gas into the spray pipe. The high-pressure gas blows out along the back-blowing head, blowing the impurities remaining on the surface of the screening mesh belt into the collection drawer, completing instant cleaning, avoiding impurity residue and clogging. Since the back-blowing head completes the back-blowing cleaning almost instantly, the cleaning action is fast, the structure is simple and practical, and the cleaning efficiency is significantly improved. At the same time, it avoids the wear phenomenon caused by the movement of the scraper in the traditional structure, significantly reduces wear, thereby extending the service life and further improving the efficiency of use.

[0019] (2) This utility model uses a meat grinder and a screw conveyor. The meat grinder can quickly grind the fish meat into fine and efficient pieces, which significantly saves grinding time. The ground fish meat paste is directly transported to the fish oil extraction chamber through the screw conveyor, avoiding the phenomenon of conveying blockage and improving the overall stability of operation.

The fish oil falls onto the top surface of a screening mesh belt 6, which filters and separates the oil. The fish oil passes through the screening mesh belt 6 and falls into an oil receiving tank 18. Impurities continue to rotate with the screening mesh belt 6 until they reach the back-blowing head 14. A high-pressure air pump 17 injects high-pressure gas into the nozzle 13. The high-pressure gas is blown out along the back-blowing head 14, blowing the impurities remaining on the surface of the screening mesh belt 6 into the collection drawer 7. The cleaning process is instantaneous, avoiding impurity residue and clogging. Because the back-blowing head 14 completes the back-blowing cleaning almost instantly, the cleaning action is fast, the structure is simple and practical, and the cleaning efficiency is significantly improved. At the same time, it avoids the wear caused by the movement of the scraper in the traditional structure, significantly reducing wear and thus extending the service life and further improving the efficiency of use. Meanwhile, the meat grinder 1 can quickly and efficiently grind the fish meat, saving grinding time significantly. The ground fish meat paste is directly transported to the fish oil extraction chamber 3 through the screw conveyor 2, avoiding the phenomenon of conveying blockage and improving the overall stability of operation.

[0030] Specifically, the drive roller 11 and the driven roller 12 are rotatably connected to the separation box 5 through roller shafts, and the roller shafts pass through the separation box 5 and are rotatably connected to the separation box 5 through sealed bearings. A material collection drawer 7 is inserted into the surface of the separation box 5 on one side of the screening screen belt 6, below the screening screen belt 6 and on the other side of the separation box 5.

[0043] In this implementation plan, the backflush head 14 is widely distributed, which improves the comprehensiveness and efficiency of backflush.

[0044] Working principle: During fish oil extraction, fish meat is fed into a meat grinder 1 and pulverized. It is then conveyed by a screw conveyor 2 to the fish oil extraction chamber 3 for separation and extraction. Subsequently, an oil suction device 4 draws the fish oil into a separation box 5. The fish oil falls onto the top surface of a screening mesh belt 6, which filters and separates the oil. The fish oil passes through the screening mesh belt 6 and falls into an oil receiving tank 18. Impurities continue to rotate with the screening mesh belt 6 until they reach the back-blowing head 14. A high-pressure air pump 17 injects high-pressure gas into the nozzle 13, which is then blown out along the back-blowing head 14, blowing the impurities remaining on the surface of the screening mesh belt 6 into the collection drawer 7, thus completing the extraction process. Instant cleaning avoids impurities and blockages. Because the back-blowing head 14 completes back-blowing cleaning almost instantly, the cleaning action is fast, the structure is simple and practical, and the cleaning efficiency is significantly improved. At the same time, it avoids the wear caused by the movement of scrapers in traditional structures, significantly reducing wear and extending service life, and further improving efficiency. Meanwhile, the meat grinder 1 can quickly and finely grind fish meat, saving grinding time significantly. The ground fish meat paste is directly transported to the fish oil extraction chamber 3 through the screw conveyor 2, avoiding conveyor blockage and improving the overall operational stability.
