1–2 Ton/Hour Automatic Twin-Screw Fish Feed Extruder Production Line

Description

The 1–2 Ton/Hour Automatic Twin-Screw Fish Feed Extruder Production Line is a complete processing solution for producing nutritionally formulated aquatic feed at a commercial scale. It combines raw-material receiving, grinding, mixing, conditioning, extrusion, cutting, drying, oil coating, cooling, screening, and packaging into a coordinated production system. At the centre of the line is a 110 kW twin-screw extruder. The two intermeshing screws transport, mix, cook, shear, and compress the conditioned feed mixture inside the extrusion barrel. The material is then forced through a selected die to form pellets of the required diameter and shape. By adjusting the formulation, moisture level, temperature, pressure, screw speed, cutting speed, and die configuration, the line can produce floating or sinking pellets for different aquatic species and growth stages. Pellet diameters can be selected from approximately 0.5–2 mm, 2–4 mm, 4–6 mm, 6–8 mm, or 8–12 mm. The extrusion process can improve ingredient integration, pellet uniformity, water stability, and feed handling. However, the final nutritional profile depends on the raw-material formulation, dosing accuracy, extrusion parameters, drying conditions, oil application, and laboratory quality control.
