Description

Technical Field

[0001] This invention relates to the field of puffed shrimp feed production technology, specifically to a raw material pretreatment, cooking, and homogenization device and method for puffed shrimp feed production. Background Technology

[0002] Extruded shrimp feed is a type of aquatic compound feed processed through extrusion puffing technology. It is not simply a matter of grinding and mixing raw materials such as fish meal, soybean meal, and flour, but rather allowing these raw materials to undergo a "pressure cooker"-like physicochemical change in a high-temperature and high-pressure extruder, and finally releasing them instantly to produce shrimp feed extruded pellets with the required bulk density.

[0003] Currently, extrusion equipment is the core processing equipment in the production of aquatic feed, especially shrimp feed. Traditional extruders typically have a forming die fixedly installed at their discharge end. After the material is cooked under high temperature and pressure inside the barrel, it is extruded through specific holes in the die to form the desired shape.

[0004] This method of discharging material using fixed molds has revealed numerous drawbacks in actual production. First, the mold's aperture and opening ratio are fixed. When the material formula, moisture content, or output fluctuates, the pressure of the material flowing through the mold changes accordingly, easily leading to material blockage due to pressure imbalance. Once blockage occurs, the machine must be stopped immediately, and the heavy mold assembly must be disassembled, cleaned, and maintained manually. This process is time-consuming, labor-intensive, and severely disrupts production continuity. Second, during long-term use, the mold suffers severe wear due to high-speed material erosion and frequent disassembly and assembly, requiring periodic replacement. This not only increases spare parts costs but also further reduces the overall operating efficiency of the equipment.

[0005] Therefore, this invention proposes a raw material pretreatment, cooking, and homogenization device and method combined with the production of extruded shrimp feed to solve the aforementioned problems. Summary of the Invention
