Description

Technical Field

[0001] This utility model relates to the field of fish oil preparation technology, and in particular to a feeding device for fish oil preparation and production. Background Technology

[0002] With the rapid development of technology, fish oil is increasingly in demand in the food, pharmaceutical and health product industries due to its rich nutritional value and wide range of applications. In the traditional fish oil preparation process, the feeding process often suffers from problems such as low efficiency and uneven raw material processing. During the production of fish oil, fish paste needs to be added continuously to facilitate the subsequent pressing of fish oil. The existing fish meat is turned into fish paste by a mincing blade in the processing tank, but some fish meat still adheres to the inner wall of the tank after mincing and is difficult to scrape off, resulting in a certain degree of waste. In addition, the pressed fish oil is also mixed with some impurities from the fish meat, which affects the quality of the fish oil.

[0003] When applying for this utility model, the applicant searched and found that a Chinese patent disclosed "A feeding device for fish oil production" with application number "202421371457.9". This patent discloses a feeding device for fish oil production, including a processing tank, with a fish meat feeding device installed at the upper end of the processing tank and a fish oil pressing unit installed inside the lower end of the processing tank. This invention utilizes a fish meat feeding device to mince cleaned fish meat using spiral and conical blades. The fish meat is fed into the upper chamber while being minced and discharged through the extrusion hole, improving the fineness of the minced fish meat and facilitating efficient oil extraction. After the fish paste is fed, a scraper removes any remaining fish meat from the inner wall of the upper chamber, reducing waste and facilitating subsequent cleaning. A fish oil pressing unit is installed, where the minced fish enters a filter cylinder. A cylinder forces the pressure plate to extract the fish oil from the fish paste. The filter cylinder also reduces the discharge of impurities, thus improving the quality of the fish oil. Furthermore, a filter screen embedded in the oil outlet pipe further filters the discharged fish oil. Utility Model Content

[0011] Preferably, the bottom end of the feed pipe is located inside the outer fixed cylinder and outside the inclined baffle, and the fish meat entering through the feed pipe reaches the bottom of the outside of the inclined baffle.

[0012] Preferably, the spiral blade rotates with the main connecting rod and the auxiliary connecting rod, and the spiral blade pushes the fish paste out of the hole of the extrusion disc.

[0013] This utility model provides a feeding device for fish oil preparation and production, which has the following beneficial effects:

[0014] The device of this utility model uses a motor to drive the rotating shaft to rotate, which in turn drives the rotating disk and its main connecting rod, secondary connecting rod and spiral blade to rotate at high speed. During the rotation, the spiral blade can not only fully cut and stir the fish paste, but also use its special spiral structure to evenly squeeze the fish paste out of the extrusion hole of the extrusion disk, ensuring that the fish paste meets the requirements after being stirred and crushed.

[0015] The upper and lower fixing rods, as well as the main and auxiliary scrapers in this invention, enhance the cleaning effect of the device on the inner wall of the mixing drum, avoiding the residue and waste of raw materials. The stirring blades enable secondary stirring of the fish paste in the middle of the mixing drum, making the fish paste more uniformly mixed, providing high-quality raw materials for subsequent fish oil extraction, improving the efficiency and quality of fish oil preparation, and reducing production costs.

[0023] Furthermore, the bottom of the rotating shaft 6 is vertically fixedly connected to an upper fixing rod 17 and a lower fixing rod 20 that are parallel to each other, and the ends of the upper fixing rod 17 and the lower fixing rod 20 are respectively fixedly connected to a main scraper 16 and a secondary scraper 19.

[0024] Furthermore, a stirring blade 18 is fixedly connected to the bottom of the rotating shaft 6, located between the upper fixed rod 17 and the lower fixed rod 20.

[0025] Furthermore, the surface of the extrusion disc 15 is uniformly provided with extrusion holes, and the center of the extrusion disc 15 is rotatably connected to a rotating shaft 6.

[0026] Furthermore, the spiral blade 9 is located between the inner fixing cylinder 14 and the outer fixing cylinder 1, and the spiral blade 9 does not contact the surfaces of the inner fixing cylinder 14 and the outer fixing cylinder 1.

[0027] Furthermore, the outer edges of the auxiliary scraper 19 and the main scraper 16 are in close contact with the inner surface of the mixing drum 4, and the stirring blade 18 rotates in the middle of the mixing drum 4.

[0028] Furthermore, the bottom end of the feed pipe 3 is located inside the outer fixed cylinder 1 and outside the inclined baffle 8, and the fish meat entering through the feed pipe 3 reaches the bottom of the outside of the inclined baffle 8.

[0029] Furthermore, as the main connecting rod 12 and the secondary connecting rod 13 rotate, the spiral blade 9 pushes the fish paste out of the hole in the extrusion disc 15.

[0030] Working principle: The motor body 5 is fixed to the top of the outer fixed cylinder 1 by the fixing frame 7.
