The global expansion of aquaculture relies heavily on a consistent supply of high-quality, nutritious feed. Among the various types, floating fish feed has become the industry standard for many species due to its ease of management, digestibility, and reduced water pollution. The production of this feed is a marvel of modern agro-processing, achieved through a sophisticated and integrated production line.It can make kinds of feed, such as food fish, catfish, shrimps, crab, etc. the fish pellet made by the machine can float on water more than 24 hours. Gelatinization degree can reach 90%, enhance the output of fodders, it is suitable for making floating feed, pet food, fish fodder. The diameter of particle is 0.6-16mm. Promising fodder output evenly and continuously.
A floating fish feed production line is a series of interconnected industrial machines designed to transform raw ingredients—such as fishmeal, soybean meal, cereals, vitamins, and minerals—into uniform, extruded pellets that float on water for a prolonged period. This continuous process ensures high output, consistent quality, and precise control over the feed’s nutritional and physical properties.
The key to the “floating” characteristic lies in the cooking and puffing action of the extrusion process, which creates a porous, air-filled structure within each pellet.Raw materials: adopts soya meal, fish meal, bone meal, rice bran etc. as raw materials.

Voltage in China: Three phases: 380V/50Hz, Single phase: 220V/50Hz, we can make it according to customers’ Local voltage according to different countries.
Machine materials: All the aquaculture fish feed machine production line are made by stainless steel, this line is with reasonable design and with high automation; the screws are made by alloy steel, with building block system structure and self-cleaning function.
Main Parts of Twin screw extruder with electricity heating system:
a. The screws are made by alloy steel (38CrMoAL) and special craft by nitriding process, The HRC hardness is around 60—62, it has good self-cleaning ability and does not need to discharge or clean the barrel and screw, when roasting or replacing of materials.
b. The extrusion barrel is constructed of carbon steel, is made by #45 steel, stainless steel coating.
c. The gearbox has automatic lubrication function, with extends gear life.
Customized Tilapia Catfish Floating Sinking Fish Feed Making Machine also has a variety of configurations. The production equipment can adjust the raw materials, temperature, moisture and other process parameters, so that the product has the characteristics of novel shape, unique taste, rich nutrition, and delicate tissue, which is suitable for the taste of different pets. The pet food production line is widely used in the production of dog, cat, fish, shrimp, fox, bird and various pet feeds, and is an ideal choice for different manufacturers.
Advantage :
1. It can suit various raw materials, such as corn flour, fish mill, meat mill and so on.
2. You can get various shapes of pet food, such as: rings, triangle, core flling pet food etc.
3.We not only have the basic pet food formula,but also the professional formula based on different age pets.
4. The machines performance and products quality reach to the most advanced level in the world.
5. High efficiency, low consumption, easy to operate and maintain.
A floating fish feed production line is more than just a series of machines; it is a finely tuned system that integrates food science, mechanical engineering, and nutritional expertise. By transforming basic agricultural commodities into highly engineered, floating feed, this technology plays an indispensable role in supporting sustainable and efficient aquaculture, helping to meet the world’s growing demand for fish protein.
