In the production process of fish paste products, mincing is the first key step in transforming fish meat into delicate fish paste. After the fish meat is collected, there are still problems such as uneven thickness of muscle fibers and a small amount of fascia. These need to be broken down into a uniform paste through mincing, laying the foundation for subsequent processes such as fine filtration and pounding. With its strong cutting ability and precise crushing control, the fish paste mincer processes fish meat into initial fish paste that meets quality requirements. It is an indispensable core equipment in the fish paste processing production line, directly affecting the texture and quality of the final product. 

The material selection of the fish paste mincer strictly follows food processing hygiene standards. All parts that come into contact with fish meat are made of 304 food-grade stainless steel. This material has excellent corrosion resistance and can withstand the erosion of water, protein in the fish meat, and cleaning agents during processing, preventing metal rust from contaminating the fish paste; the surface is finely polished to reduce fish meat residue and bacterial growth, meeting the standards for food-contact metal materials and products. The equipment frame is made of high-strength carbon steel welding, with sandblasting rust removal and food-grade paint spraying, ensuring that the overall structure is strong, durable, and easy to clean and maintain. 

I. From a structural layout perspective, the fish paste mincer adopts a horizontal structure design, mainly consisting of a feed hopper, auger pusher, cutting assembly, discharge port, and drive system. There is an adjustable baffle at the bottom to control the feeding speed; the auger pusher is installed inside the barrel and uses spiral blades to evenly push the fish meat towards the cutting assembly; the cutting assembly is the core working part, consisting of a fixed cutter and a rotating cutter group; the cutter is distributed with discharge holes of different diameters; the drive system uses a variable frequency speed reduction motor to provide stable power for the equipment operation, and the speed can be adjusted according to needs. 

II. In terms of working principle, the fish paste mincer achieves fish meat refinement through the synergistic effect of spiral propulsion and cutting and crushing. When the fish meat enters the barrel from the feed hopper, the auger pusher rotates under the drive of the motor, generating axial thrust to continuously push the fish meat towards the cutting area. In the cutting assembly, the rotating cutter group rotates at high speed, forming a shearing action with the fixed cutter, cutting the fish meat into small particles. At the same time, the fish meat is extruded through the discharge holes on the cutter under the action of the pushing pressure, forming a uniformly granular fish paste. By controlling the rotational speed of the rotating cutter group and the diameter of the cutter holes, the fineness of the fish paste can be precisely adjusted to meet the processing needs of different products. 

Mincing effect control is a technical focus of the fish paste mincer. The equipment achieves precise control through a triple adjustment mechanism: First, it is equipped with cutters of different diameters. The smaller the diameter, the finer the minced fish paste particles; second, variable frequency speed regulation technology is used to adjust the cutting frequency by changing the rotational speed of the rotating cutter group. The higher the speed, the more thorough the fish meat crushing; third, the feeding speed and pushing pressure are adjusted to ensure that the fish meat is fully processed in the cutting area, avoiding uneven crushing due to too fast feeding. This multi-dimensional control capability allows the uniformity of fish paste particles to reach over 90%, meeting the texture requirements of different fish paste products. 

In terms of operation and maintenance, the fish paste mincer embodies a user-friendly design concept. The cutting assembly adopts a quick-release structure, connected by buckles or bolts, and disassembly and cleaning only takes 10-15 minutes, facilitating daily maintenance and tool replacement. The equipment is also designed with an overload protection device. In addition, there is a cooling layer outside the barrel, which can introduce cold water to lower the temperature during processing, preventing the fish meat from deteriorating due to frictional heat. 

The application of the fish paste mincer brings significant benefits to processing enterprises. First, it increases fish meat crushing efficiency by 4-6 times; a single unit can process 800-3000 kilograms of fish meat per hour, meeting the needs of large-scale production; second, uniform fish paste particles provide a good foundation for subsequent fine filtration and pounding processes, improving subsequent processing efficiency; third, precise crushing control reduces the damage to fish meat cells, maximizing the retention of protein and fresh flavor substances in the fish meat, improving product quality; finally, automated mincing reduces manual contact, reducing the risk of microbial contamination, and extending the shelf life of the product. 

As the basic equipment for fish paste processing, the fish paste mincer is characterized by its efficient crushing capacity, precise texture control, and stable operating performance.
