company news about What equipment does a fish meal production line include? What are its functions?

The fish feed production line uses cereals, beans, meat meal and fish meal as the main raw materials. After extrusion, puffing, drying and seasoning, the products produced have a unique taste, are rich in nutrition and are easier to absorb.

Fish Feed Production Line Equipment Components
(a) Mixer: Corn flour, rice flour, soybean meal, fish meal, meat meal, grain meal, additives, and other raw materials are mixed with water in a certain proportion and thoroughly stirred.
(b) Loader: A motor-driven screw conveyor delivers the mixed raw materials to the feed hopper of the twin-screw extruder. This equipment provides convenient and fast loading, saves labor, and is highly efficient.
(c) Twin-screw Feed Extruder: The mixed raw materials undergo high temperature and pressure, and the twin screws extrusion transforms the starch structure of the raw materials into easily absorbed nutrients. The mixed raw materials are then extruded through the feed die. The speed of the rotating motor is adjusted until the feed pellets are of uniform size and length. The specific pellet size and shape are achieved by replacing the die. The feed extruder uses advanced variable frequency speed regulation technology, which is more energy-efficient and provides better speed control. The inverter panel allows for intuitive display of the motor's operating current and speed, ensuring stable operation.
(d) Conveyor: The produced feed pellets are transported to the multi-layer drying equipment. (e) Multi-layer drying ovens: Drying ovens are available in electric, fuel, gas, and steam drying ovens. The temperature is automatically adjusted by a control cabinet. Transport within the drying ovens is stable and has a low failure rate. Feed pellets circulate on multi-layer S-shaped tracks, drying them to a desired moisture content and extending their shelf life.
(f) Oil spraying and seasoning line: Oil sprayers apply oil, lubricants, and other ingredients. Seasoning drums, including octagonal drums, round drums, single-drum lifts, and double-drum seasoning lines, are configured according to production volume and product characteristics. These drums are used to spray oil onto the feed surface. Minced meat and spices are sprayed simultaneously and evenly distributed. This process also removes burrs and rough edges from the feed pellets, resulting in a smoother surface.
(h) Cooling conveyor: This cools the surface temperature of the dried feed pellets, promoting oil solidification and lowering pellet temperature for easier packaging.
(i) Vibrating screen: This screens out excess foreign matter and pellet residue to ensure quality.

Compared with traditional feed production methods, fish feed production lines have the following advantages:

1. Improved feed utilization: Because the fish feed extruder expands feed under high temperature and pressure, the expanded feed is easily digested and absorbed by fish, improving feed utilization.
2. Improved feed quality: The expanded feed particles are uniform in size and have a moderate density, reducing feed waste and pollution while improving feed quality.
3. Improved production efficiency: The fish feed extruder can achieve automated production, significantly improving production efficiency and reducing labor costs.
4. Energy conservation: The fish feed extruder utilizes advanced heating and extrusion technology, saving energy and reducing emissions, meeting environmental requirements.
5. Strong adaptability: The fish feed extruder can produce feed of different types, shapes, and flavors, meeting various aquaculture needs.
