Extruded feed processing equipment

1. Fish Feed Processing Machinery Price Process Flow:

Raw material crushing → Raw material (corn flour, soybean meal, starch, fish meal, etc.) preparation → Mixing and stirring → Screw conveying → Twin-screw feed extrusion forming → Elevating conveying → Drying (electric oven, gas/oil oven or steam oven) → Oil spraying → Double-drum seasoning system → Cooling conveying → Vibrating screening → Storage silo → Packaging 2. Fish Feed Production Machinery Equipment Configuration:

Wall breaker → Mixer → Screw conveyor feeder → Twin-screw extruder feed machine → Elevating conveyor → Multi-layer dryer → Double drum seasoning machine → Cooling conveyor → Vibrating screen → Packaging machine. Fish feed size range: 1.5mm, 2.0mm-10mm. This production line can process and produce aquatic feed pellets for catfish, grass carp, crucian carp, tilapia, ornamental fish, softshell turtle, bullfrog, etc.

IV. Composition of fish feed processing machinery and technology:

1. Mixer: Evenly mix various starches, additives, and a certain proportion of water required for the feed according to the formula.

2. Screw conveyor feeder: Uses a motor-driven screw to transport the mixed raw materials to the feeding hopper of the twin-screw extruder. This equipment enables convenient and fast feeding, saves labor, and is highly efficient.

3. Twin-screw extruder feed machine: Under high temperature and high pressure conditions, with the extrusion of the twin screws, the starch structure in the raw materials changes, becoming easily absorbable nutrients. The material is extruded through a feed mold, and by adjusting the rotation speed of the rotary cutter, feed pellets of uniform size and length are produced. The specific pellet size and shape can be obtained by changing the mold. The feed extruder adopts variable frequency speed control technology, which is more energy-efficient and provides precise speed control. The current and rotation speed during motor operation can be directly viewed on the inverter panel, ensuring equipment safety. The screw has an automatic cleaning function, making it self-cleaning and easy to use.

4. Conveyor: Transports the produced feed pellets into the multi-layer drying equipment.

5. Multi-layer oven: The oven is available in electric, fuel-fired, gas, and steam types, with temperatures adjustable between 0-150°C via a control cabinet. The interior features a stainless steel mesh belt for smooth conveying and low failure rates. Feed pellets circulate through multi-layer S-shaped tracks, drying them to a safe moisture content to extend shelf life.

6. Spray seasoning line: The oil sprayer applies oils, attractants, etc. The seasoning drum comes in octagonal, cylindrical, single-drum lift, and double-drum seasoning line configurations, configured based on output and product properties. Oil is sprayed onto the feed surface, along with even distribution of minced meat and spices. This process also removes burrs and rough edges from the pellet surface, making it smoother.

7. Cooling conveyor: reduces the surface temperature of dried feed pellets, promotes fat solidification, lowers pellet temperature, and facilitates packaging.

8. Vibrating screen: to sieve out excess scattered material and granular residue.

9. Packaging machine: Manual sealing machine and automatic packaging machine can be used. For details, please contact the manufacturer.
