Catfish feed processing machinery and equipment

Fish is rich in nutritional value, with twice the protein content of pork. Fish is rich in thiamine, riboflavin, niacin, vitamin D and a certain amount of calcium, phosphorus, iron and other minerals. Although the fat content in fish is low, it contains unsaturated fatty acids, but the fatty acids in it have been proven to have hypoglycemic, cardioprotective and cancer-preventing effects. The vitamin D, calcium, and phosphorus in fish can effectively prevent osteoporosis. With the development of society and the improvement of living standards, people's requirements for food varieties have gradually increased. People have paid more and more attention to the nutritional value of fish. Fish has almost become a common dish on the public table. As market demand increases, the aquaculture industry has To develop in the direction of scale, intensification, and specialization, major breeding bases have increasingly higher requirements for aquatic feed. The feed produced by traditional sinking fish feed has poor water stability, fast settling speed, and is easy to cause feed loss and water quality. Disadvantages such as pollution and food waste have been gradually eliminated by the modern aquaculture industry. According to research, there is a huge gap in domestic puffed fish feed. Many farmers cannot buy puffed fish feed at all. The fish feed produced by Jinan Datong puffed fish feed machinery has completely solved the problem. These disadvantages, the fish feed can float on the water surface, reduce feed waste and water pollution caused by settlement, and better maintain the living environment of fish. After puffing and extruding, the internal structure of the fish feed changes, which is more conducive to fish digestion and absorption. More and more Aquaculture farmers and feed factories have installed fish feed production equipment.

This production line produced by Datong Machinery can produce and process grass carp, soft-shell turtle, catfish, crucian carp, bullfrog, ornamental fish, tilapia and other aquatic feeds.

The production line has high and stable output and can automatically clean the screw.

1. Catfish feed processing machinery process flow:

Crushing of raw materials → Preparation of raw materials (corn flour, soybean meal, starch, fish meal, etc.) → Mixing and stirring → Screw conveying → Twin screw feed extrusion molding → Lifting and conveying → Drying (electric oven, gas fuel oven or steam oven) → Oil injection →Double-cylinder seasoning system→Cooling and conveying→Vibration screening→Storage silo→Packaging.

2. Catfish feed processing machinery and equipment configuration:

Wall breaking machine → mixer → screw conveyor feeding machine → twin-screw extruded feed machine → lifting conveyor → multi-layer dryer → double drum flavor mixing machine → cooling conveyor → vibrating screen → packaging machine

Fish feed size range: 1.5mm, 2.0mm-10mm.

This production line can produce and process aquarium feed pellets such as catfish, grass carp, crucian carp, tilapia, ornamental fish, soft-shell turtle, bullfrog, etc.

3. There are five main models of catfish feed processing machinery:

Floating fish feed production line, fish feed production line, puffed fish feed production line, ornamental fish feed production line, floating fish feed production line, floating fish feed production line, floating fish feed production equipment, puffed feed machinery, puffed feed processing equipment, catfish feed production line, tilapia Fish feed processing equipment, carp feed processing machinery, tropical fish feed

4. Catfish feed processing machinery process composition:

Mixer machine: Mix the various starches, additives and a certain proportion of water required for the feed evenly according to the ratio.

Screw conveyor feeding machine: The motor is used to power the screw conveyor to transport the mixed raw materials into the feeding hopper of the twin-screw extruder. This equipment is convenient and fast for feeding, saves labor and is highly efficient.

Twin-screw extruded feed machine: When the mixed raw materials are extruded in a high-temperature and high-pressure environment and twin-screws, the starch structure in the raw materials changes and becomes easily absorbed nutrients, which are extruded through the feed die. By adjusting the rotation of the rotary cutting motor The speed is adjusted until the feed particles are of the same size and length. The specific particle size and shape are obtained by changing the mold. The feed extruder adopts frequency conversion speed regulation technology, which is energy-saving and has precise speed control. The current and speed of the motor during operation can be directly seen through the frequency converter panel to ensure the safety of the equipment.

The screw has an automatic cleaning function and is self-cleaning and easy to use.

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

Multi-layer oven: The oven is divided into electric oven, oil oven, gas oven and steam oven. The temperature can be adjusted automatically through the control cabinet between 0-150 degrees. The inside of the oven is a stainless steel mesh belt, which ensures smooth transportation and low failure rate. The feed pellets circulate through multi-layer S-shaped tracks to dry the feed pellets to a safe moisture content and increase the shelf life.

Spray seasoning line: The oil spray machine sprays oil, attractants, etc. The seasoning cylinders include octagonal cylinders, cylinders, lifting single drums, and double drum seasoning lines. They are configured according to the output and product properties. The oil is sprayed on the feed surface and sprayed at the same time. Sprinkle minced meat and spices evenly. After this process, burrs and burrs on the surface of the feed pellets can also be removed, making the surface of the feed pellets smoother.

Cooling conveyor: lowers the surface temperature of drying feed particles, promotes oil coagulation, lowers the temperature of the particles, and facilitates packaging.

Vibrating screen: Screen out excess external materials and granular residue.

Packaging machine: Manual sealing machine and automated packaging machine can be used. Please call the manufacturer for specific details.
