Feed extruder production line is a feed pellet production line. It mainly processes crushed grains, straw, husk, fish meal, meat meal, a bone meal into feed pellets to feed aquatic animals and pets. The whole fish feed pellet production line includes two types, dry process, and wet process. Both lines output feed pellets with high automation. According to different raw materials and capacity demands, we provide different models of machines for customers’ choice.

What are the applicable scopes of the fish feed production line?
The whole fish feed production line widely applies to the aquaculture industry and pet food processing industry. And this is fully in line with the modernization of the agricultural machinery production line. In recent years, this production line has been favored by the majority of consumers from America, Nigeria, Ghana, Peru, Tanzania, Pakistan, Colombia, Niger, Angola, Malaysia, etc.
Dry process feed extruder production line
Raw material crusher→ mixer→ screw conveyor→ extruder→ pneumatic conveyor→ dryer→ bucket conveyor→ counter flow cooler→ roller sprayer→ bucket conveyor→ finished product bin→ packing machine
The crusher machine crushes the raw material, hammer mill machine is always a good choice. The screw conveyor transferred the crushed material into the mixer, after equably blending, the material goes into the fish food making machine. Extruder squeezes and outputs pellets into the pneumatic conveyor, and then the pellets are transferred to the dryer.
The mesh belt dryer dries pellets layer by layer, then goes out into the counterflow cooler. The pellets come from the cooler, then go into the spraying machine and it sprays pellets evenly. Some grease will increase the palatability and allure of pellets. Bucket conveyor will send the pellets to finished product bin, to some consumers, the production line is completely finished now. But customers can also choose to add one packing machine to package those pellets into bags, which can be sold easily.
Wet process feed extruder production line
Raw material crusher→ mixer→ screw conveyor→ conditioning apparatus→ boiler→ fish feed extruder→ pneumatic conveyor→ dryer→ bucket conveyor→ counter flow cooler→ roller sprayer→ bucket conveyor→ finished product bin→ packing machine
The raw material after crushing by the crusher, then being transferred by screw conveyor into the mixer. After equably stirring and mixing, the material goes into the conditioning apparatus. The conditioning apparatus connects to the boiler, which turns material into steam, and then the conveyor transfers material into the pet food extruder. This step is the main point that’s different from the dry process production line.
Extruder outputs pellets into the pneumatic conveyor, and then the pellets go to the dryer. Mesh belt dryer dries pellets, then pellets go out into counter flow cooler. After cooling, the pellets go into the roller sprayer and get grease sprayed evenly. The bucket conveyor will send the pellets to the finished product bin, finally the packing machine packages pellets into bags.
Difference between dry and wet process feed extruder production line
The dry process is to crush the raw material and mix it well, then expand it into pellets directly.
The wet process needs the steam boiler, and the extruder also needs to equip with a conditioning apparatus, which connects with the boiler through the pipe. After crushing and mixing, the advanced conditioning apparatus and steam can fully pre-mature the pellets, and then the extruder can squeeze the material into pellets.
Compared to the same power of two types, the wet process machine output is higher, the material will be slightly delicate. However, the wet process needs a steam boiler, and the production process is relatively intricate.
Main machines introduction
The crusher part of the feed pellet production line mainly consists of two machines, the grain grinder machine, and the cyclone. We provide a hammer mill machine like a crusher, which uses hammers and sieves to output fine powder of raw material. Cyclone collects the dust, and reduces the internal pressure of the crusher, then increases the capacity.

The conveyor includes a screw conveyor, pneumatic conveyor, and bucket conveyor. The conveyor is an important machine to improve the automation of the production line.
|Real consumption power||0.75KW|
It’s the main machine of the whole production line. It decides the capacity of the line and varies of models mainly distinguished by output. The shape and figure are adjustable by changing the molds of the extruder.

The fish feed production line adopts a mesh belt dryer machine. It dries pellet layer by layer evenly, can remove the moisture content of feed pellets. The dryer can increase the storage time of pellets. Besides, the conveyor transfers the pellet into the dryer automatically, which saves a lot of human labor.
Counter flow cooler
It is the most advanced cooling technology of pellet feed in the world, mainly for the cooling of high-temperature feed pellets after pelletization. The feed pellets through the cooler are not easy to deteriorate and can be preserved for a long time. It’s a necessary machine among the product line.
|Quantity of fan||4pcs|
|Power of fan||0.15kg/pcs|
Oil spraying machine
