Datong Fish Feed Extruder Extruded Fish Feed Process

There is nothing more delicious than fish meat. Fish-based foods have become very popular among the public, and more and more people who focus on health and fitness prefer fish over other meats. Due to the nutritional content and tender texture of fish, it is favored by consumers. Below, we introduce the process composition of fish feed extrusion machinery for producing fish feed:

Mixer: Fully and evenly mix raw materials such as corn flour, rice flour, soybean flour, fish meal, meat meal, grain flour, additives, and the required moisture for the ingredients.

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

Twin-screw extruder: Under high temperature and high pressure conditions and the extrusion of the twin screws, the starch structure in the mixed raw materials changes, becoming easily absorbable nutrients. The material is extruded through a feed mold, and by adjusting the speed of the rotary cutter motor, feed pellets of uniform size and length are produced. The specific pellet size and shape can be achieved by changing the mold. The feed extruder adopts advanced variable frequency speed control technology, which is more energy-efficient and provides more precise speed control. The current and speed during motor operation can be directly observed on the inverter panel, allowing real-time monitoring of equipment operation.

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

Multi-layer Oven: The oven is available in electric, oil-fired, gas-fired, and steam types, with temperatures ranging from 0 to 150 degrees Celsius, adjustable via the control cabinet. The interior features a stainless steel mesh belt for smooth transportation and low failure rates. Feed pellets circulate through multi-layer S-shaped tracks, drying them to a safe moisture content and extending shelf life.

Spray Seasoning Line: The oil sprayer applies oils, attractants, etc. The seasoning drum comes in octagonal, cylindrical, single-drum lifting, and double-drum seasoning line configurations, configured based on output and product properties. It sprays oil onto the feed surface while evenly distributing minced meat and spices. This process also removes burrs and rough edges from the feed pellet surface, making it smoother.

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

Vibrating screen: removes excess scattered material and pellet debris, ensuring quality while enabling raw material reuse.

Packaging machine: manual sealing machines and automated packaging machines are available; for details, please contact the manufacturer.
