Feed Pellets Extruder Floating Fish Feed Production Line

4.9/5 - (98 votes)

The feed pellet extruder machine is commonly used in the fish feed production line. The whole line 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 fish feed production lines?

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.

Brief introduction

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 equable 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 and 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. The bucket conveyor will send the pellets to the finished product bin, to some consumers, the fish feed production line is finished now. But customers can also choose to add one packing machine to package those pellets into bags, which can be sold easily.

Brief introduction

The raw material after crushing by the crusher, then being transferred by a 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.

The 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, and 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 be equipped 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 the 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


Hammer mill crusher machine

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.

Drying machine 1

The fish feed production line adopts a mesh belt dryer machine. It dries pellets layer by layer evenly and 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.
