Description

Technical Field

[0001] This utility model relates to the field of fish processing technology, and in particular to a fish bone crushing and processing device. Background Technology

[0002] In the fish processing industry, fish is an important food source, and its processing encompasses multiple stages from fishing to final product manufacturing. Fish processing aims not only to extract high-quality fish meat but also to properly handle by-products, including fish bones. Fish bones, as the main supporting structure of fish bodies, are rich in calcium and protein, but are considered waste in many food processing processes. If not properly treated, they not only take up space but may also burden the environment. Traditional methods for processing fish bones often involve direct disposal or use as low-value feed ingredients, but these methods fail to fully utilize the nutritional value of fish bones. With technological advancements, fish bone crushing and processing devices have emerged as an effective means of solving this problem. These devices mechanically crush fish bones into fine particles, facilitating subsequent reuse, such as as animal feed additives, fertilizer raw materials, or substrates for high-value extracts.

[0003] In the existing technology, the fish bone crushing and processing device uses a rotary cutter to cut the fish bones directly. However, fish bones usually still have a certain amount of fish meat on them. Since the fish meat is more economical, directly crushing it together with the fish bones results in a low fish meat recovery rate. Utility Model Content

[0004] In view of this, the present invention proposes a fish bone crushing and processing device to solve the problems mentioned above.

The other end passes through the L-shaped frame 9 and is connected to a second motor 22. The second motor 22 is located on the L-shaped frame 9.

[0023] When the fish bone crushing and processing device is working, the fish bones with meat are placed on the first conveyor belt 3. The fish bones are transported to one end by the first conveyor belt 3 and fall from the end. They enter the housing 6 through the feed hopper 5 below. The fish bones are located between the extrusion belt 19 and the outer wall of the rotating drum 20. At this time, the first motor 8 rotates and drives the rotating drum 20 to rotate, rolling the fish bones between the extrusion belt 19 and the rotating drum 20. After being squeezed by the extrusion belt 19, the fish meat is squeezed into the interior of the rotating drum 20 through the screen holes 21. As the rotating drum 20 rotates, the spiral scraper 29 cuts the fish meat squeezed into the rotating drum 20, thereby separating the fish meat from the fish bones. The fish meat is pushed out from the opening 23 of the rotating drum 20 and falls into the discharge channel 12 at the bottom of the discharge hood 11. The fish bones fall into the mixing tank 10 from the discharge port 7. The rotating cutting blade 32 crushes the fish bones, which improves the fish meat recovery rate. Crushing the fish bones is beneficial for subsequent recycling processing.

[0024] Preferably, it also includes a discharge pipe 15 and a discharge valve 16, wherein the discharge pipe 15 is located at the bottom of the mixing tank 10 and the discharge valve 16 is located on the discharge pipe 15.
