With the development of the aquaculture industry in the direction of large-scale, intensive and professional, its requirements for aquaculture feeds are becoming higher and higher. The traditional powder compound feed, pellet compound feed, and other types of compound feed all have disadvantages, such as poor water stability, fast settling rate, easy to cause feed loss, and water pollution. It is no longer suitable for the development of modern aquaculture. Puffed fish feed has completely solved these drawbacks, and more and more aquaculture farmers and feed mills have installed puffed feed machine equipment.
Tilapia Feed Production Line Process: Large fish feed extruder production line
Raw material crushing → Preparation of raw materials (corn meal, soybean meal, starch, fish meal, etc.) → feed mixer → conveyor → twin screw fish feed extruder → conveyor → drying equipment (electric oven, gas oil oven or steam oven) → fuel injection → double-cylinder seasoning system → cooling conveyor → screening → silo → packaging machine
Extruded Fish Feed Processing Equipment Configuration: Fish Feed Pellet Machine Hot Sale
Crusher → Mixer → Feeder → Twin Screw Fish Feed Extruder → Conveyor → Multi-layer Drying Equipment → Flavoring Machine → Cooler → Vibrating Screen → Packaging Machine
Fish feed size range: 1mm, 1.5mm, 2.0mm-10mm.
This fish feed production line can produce and process feed pellets such as catfish, grass carp, tilapia, ornamental fish, turtles, bullfrogs, and so on.
Fish Feed Production Line Equipment Introduction
- Mixer: Addinga certain percentage of water to the raw material corn flour, rice flour, soybean flour, fish flour, meat flour, cereal flour, etc. and mix well.
- Feeding machine: Using the motor as the power, the screw-type transport, transfer the mixed material to the hopper of the twin-screw extruder.This equipment is convenient and efficient for feeding, saving labor and high efficiency.
- Twin-screw feed extruder: Under the condition of high-temperature high pressure and twin-screw extrusion of the mixed raw materials. The starch structure of the raw materials changes and becomes easily absorbed nutrients. It extruded through the feed mold and adjusted by rotary cutting, until the same size pellets extruded.The specific particle size and shape are obtained bychanging the mold. The fish feed extruder uses advanced frequency conversion speed regulation technology, which is more energy-saving and more accurate speed control. The current and speed of the motor can be directly seen through the inverter panel to ensure the safety of the equipment.
- Conveyor: The produced feed pellets conveyed into the multilayer drying equipment.
- Multi-layer oven: The oven divided into electric oven, fuel oven, gas oven,and steam oven. The temperature adjusted throughthe control cabinet between 0 and 150 degrees. The stainless steel mesh belt is inside the oven, and the conveyance is smooth and the failure rate is low. The feed pellets circulated through a multi-layer S-shaped track, and the feed pellets dried to safe moisture content to increase the shelf life.
- Spraying seasoning machine: The sprayer sprays oil, attractant, etc. According to the output and product properties, spray the fat on the surface of the feed, and at the same time spray the minced meat and spices, and spread evenly. After this process, the burrs on the surface of the feed pellets can be removed, making the surface of the feed pellets smoother.
- Cooling conveyor: Reduce the surface temperature of dried feed pellets, promote the solidification of fats, reduce the pellet temperature, and easy to pack.
- Vibrating sieve: Sieve away excess external material and granulated slag to ensure quality while ensuring the reuse of raw materials.
- Packaging machine: Manual sealing machine and automatic packaging machine can be used.
