Fish Feed Making Plant for Sale

Fish feed production is an important factor in large-scale fish farming and aquaculture. It has a large impact on fish growth efficiency and aquaculture costs. The use of floating fish feed has increased significantly over the past few decades as it is a high quality, environmentally friendly fish feed with superior water stability, better flotation characteristics, less pollution and zero waste . All these make it an irresistible trend in the development of the aquaculture feed industry.

Floating Fish Feed Manufacturing Process

How To Make Floating Fish Feed Pellet
Floating Fish Feed Pellets

Fish feed crusher

Raw material should be crushed to desired particle size by fish feed crusher machine. Raw material crushing is a key step. If the crushing fineness does not meet the requirements, there will be problems in the production of planktonic fish feed. The following are the requirements for the fineness of crushed raw materials.

Fish feed mixer

When using a variety of different raw materials to manufacture fish feed, mixing is necessary, and adequate mixing of materials can ensure production efficiency and improve feed quality.

Floating fish feed extruder

The extruder is the most important equipment in the whole production line, and it is the core part of the production of planktonic fish feed.

Dry type fish feed extruder does not have the steam boiler, so the dry type fish feed pellet machine is cheaper and easier to use and operate. The feed pellet made by wet type fish feed pellet machine is more smooth and with better quality because the material is ripen and mixed enough in the conditioner compared with the dry type extruder.

Fish feed dryer

Why do you need a dryer? When producing fish feed pellets, 25%-35% of raw materials need to be added. If the finished feed pellet is not dried, it will be inconvenient to store, pack and transport.

Fish feed cooler

The front is dry and already easy to store and pack, so why use a cooler? Because the moisture in the particles is evaporated by steam or high temperature during the drying process to achieve the purpose of drying, but the temperature generated by the steam or high temperature during the drying process is very high. storage and packaging.

The above are the main equipment required in the production of plankton feed, and there are other auxiliary equipment such as conveyors, silos, packaging machines, etc. Customers can choose according to their own needs.

Advantages of Fish Feed Plant

  • Advanced wet extrusion technology, high production capacity, low energy consumption.
  • The feed pellet production line occupies less land and has less construction investment. The modular structure facilitates assembly and disassembly for easy transportation and installation.
  • Adopt PLC control and alarm device. The operation is simple and convenient.
  • Wide application range. The plant can produce floating and slow settling fish feed, suitable for fish farmers and fish feed manufacturers.

Why Choose Floating Fish Feed?

Advantages of Floating Fish Feed

Because the extruded floating fish feed can float on the water surface for a long time, the feeding situation of the fish can be observed well after feeding, and it is convenient to adjust the feeding amount according to the feeding situation of the fish. At the same time, it can accurately understand the growth and health status of fish on the water surface according to the changes in food intake. Farmers can calculate the amount of bait according to the breed, specification, quantity, water temperature, bait rate and so on, and feed quickly, saving a lot of time and improving labor productivity.

Under high temperature and high pressure processing conditions, starch in the feed is matured, fat is more conducive to digestion and absorption, fiber structure and cell wall are destroyed and softened, gossypol in cottonseed meal and antitrypsin in soybean and other harmful substances, so as to improve the palatability and digestibility of the feed. In addition, due to the physical and chemical changes in the extrusion process, the powder produced by the extruded feed is generally within 1%, which directly improves the efficient utilization of the feed. Under normal conditions, the use of extruded floating feed to raise fish can save 5-10% of feed compared to powdered feed or other pellet feed.

The extruded floating fish feed does not dissolve in water for a long time. High quality floating fish feed can float for up to 12 hours, which facilitates observation and control of bait and reduces or avoids the influence of powder and residual bait on water bodies. Is very beneficial to environmental protection and the growth of fish.

The extruded feed for planktonic fish has a wide range of applicability. Floating fish feed can be used for pond fish farming, rice field fish farming, water fish farming, cage fish farming, factory fish farming, large-scale watertight aquaculture. Especially for the low density of fish farming in mountain ponds, rice fields and large surface intensive farming, the use of floating fish feed is more advantageous than other feeds.

The Essential Nutrients Required For Fish Feed Formulation


Protein is a very important nutrient in fish feed formulation. This is because protein is the main source of energy for fish. Fish need two to three times as much protein for energy as other animals.


Minerals are another essential nutrient in fish feed formulations. This is necessary for the development of fish bones. Therefore, producing fish feed must include minerals such as zinc, copper, iodine, iron, manganese and calcium.


Fish are very susceptible to bacteria. Therefore, fish need vitamins to build a strong immune system. It should be noted that fish feed formulations should contain a minimum amount of vitamins.

Other nutrients needed in a fish feed formulation include water, fat, and carbohydrates.
