How to Use a Twin screw floating fish feed pellet making machine？

Raw material pretreatment: Meets the operating standards of the Twin-Screw floating fish feed pellet extruder machine. Raw material grinding must meet standards. Protein raw materials such as fish meal and soybean meal, and starch raw materials such as corn flour and wheat flour, must be ground to 80-100 mesh to avoid large particles wearing down the extruder screw and die, while ensuring sufficient starch gelatinization. Moisture content should be controlled at 12%-14%. Too high a moisture content can cause material to stick and clog the extruder, while too low a moisture content will result in insufficient extrusion. This can be adjusted by adding water or drying the raw materials. Raw material mixing must be uniform to ensure consistent distribution of protein, starch, and additives, avoiding localized nutritional imbalances.

Standardized feeding: Ensures stable operation of the Twin-Screw floating fish feed extruder machine. Before starting the feeding system, ensure the extruder is preheated to the set temperature and pressure. Use variable frequency speed control for feeding, starting slowly and gradually adjusting to the appropriate speed after the extruder is running stably to avoid sudden large-volume feeding that could cause blockages. During the feeding process, monitor the material level in the hopper in real time to maintain a stable level and avoid fluctuations in puffing parameters caused by material interruption or uneven feeding. Simultaneously check the raw material conveying pipeline for blockages and promptly remove any residual obstructions.

Special Raw Material Handling: Adapted to the operating requirements of the Twin Screw Pet Food Extruder Machine. When adding high-fiber raw materials (such as alfalfa meal), they must be pre-crushed to at least 100 mesh, with the addition amount controlled at 10%-15%. At the same time, appropriately increase the extruder temperature and pressure to prevent fibers from affecting the puffing effect. When adding additives such as fish oil and probiotics, use a post-addition process, mixing them in after the extruder discharges to avoid high temperatures destroying their activity. Simultaneously adjust the feeding speed to ensure the additives adhere evenly to the particle surface.
