According to the diverse eating habits of different type fishes, feed should have properties – floating, slow floating or sinking, and keep stability in water for certain time so as to leave enough ingesting time for fish. Fortunately, our fish feed plant can make aquatic feed with the above characteristics, meeting the environmental protection and high efficiency requirements of feed in aquaculture. In general, it is local fish farmers that would be main potential target markets if establishing fish feed production line.

Application: 

This feed plant is designed for processing fish feed pellets which are suitable for both fish-farming and fishing as bait. The final feed pellets can be used to feed squid, tilapia, herring, grass carp, carp and other meat-eating and omnivorous fish.

The Process of the Complete Fish Feed Production Line

Crushing → Mixing → Extruding → Pellet Drying → Oil Spraying → Pellet Cooling → Pellet Packaging

Grinding—Feed Hammer Mill

To produce high quality fish feed pellets, fine grinding of raw materials is necessary. The finer the material is, the more surface area will be exposed, thus achieving the great gelatinization in conditioning. The feed hammer mill is adopted in this fish feed pellet line, which can benefit users by ideal crushing effect.

Mixing—Fish Feed Mixer

Efficient mixing is the the key step in fish feed pellet plant due to its direct influence on the feed pellet quality. Proper mixing will increase diet uniformity and improve the feedstuff quality. Our mixing machine stands out with high mixing uniformity, CV≤5%, and no segregation.

Extruding-Fish Feed Extruder

Extruding is the key process as it ensures that the feed formulation is in the correct quantities. Fish feed extruder is widely used for producing variety materials into high-grade aquatic feed pellets for fish, catfish, shrimps, crab etc. The final pellets have unique shape and good taste, high nutrition and smooth textures. For feeds of fish and shrimp, the floating time in water can be adjusted by the extrusion degree adjustment. Feed pellets dia. is 0.9-15mm. We have wet type fish feed extruder and dry type fish feed extruder for your choice.

Drying—Fish Feed Pellet Dryer

Featured by high drying uniformity and low breaking ration, mesh belt dryer is preferred to reduce the high moisture content of feed pellets coming out from the extruder.

Oil Spraying—Oil Coating Machine

Our oil coating machine is used for spraying the oil, grease, vitamin, ect. to the feed pellets surface to increase the palatability of fish feed pellets. In the drum-type spraying machine, the additives can be contacted with pellet surface sufficiently and spray evenly. After spraying, the fish feed pellets are balance and rich in nutrition.

Cooling—Count Flow Pellet Cooler

The counter flow pellet cooler is used for cooling the feed pellets just coming out from the oil coating machine. It takes advantage of counter current cooling principle to cool the pellets with high temperature and high humidity. It can avoid the shock cooling phenomenon when the cold air contacts with the hot material, thus preventing the pellet appearance crack.

Packaging—Feed Pellet Packing Machine

As the last step in floating fish feed pellet line, packaging is optional according to your needs. The automatic feed pellet packing machine is always combined with the transport mechanism and the sewing machine to constitute the automatic feed pellet weighing and packing system used in animal feed factories.

Features of Fish Feed Extrusion Line

After high-temperature and high-pressure treatment in the fish feed extrusion line, the starch is gelatinized and the protein is stratified, thus the nutritional value of the feed is greatly improved. Besides, high temperature and high pressure has good sterilization effect, making the feed good in palatability and easy to digest.

The final manufactured extrusion feed is porous and has a small specific gravity. It can float on the water for a certain period of time without sinking. Water pollution is reduced as well as the feed loss.

Extruded fish feed has low moisture content, generally 6%~9%, featured of good shape retention and can be stored for a long time. According to the experiment, the digestibility of fish can be increased by 10% to 35%.

The fish feed extrusion line is also suitavble making pet feed, such as, cat, dog etc..

How to Improve Water Stability of Floating Fish Feed Pellets

• Using finely ground ingredients so that the small cavities on the surface of the pellets are filled up, thereby reducing the rate at which water is able to penetrate into the pellet.

• Increasing the compaction of the mixture by applying more force during pelleting.

• Cooking the mash or the moist pellets (e.g. by steaming) thus increasing.

• Avoiding high concentrations of fat, water repellent or highly absorbing water ingredients in the diet mixture.

Fish feed diet formula

Diet 1- low protein diet suitable for tilapia or carp in ponds stocked at low density with natural food

Diet 2- high protein diet suitable for tilapia or carp in ponds or cages without natural food

Diet 3- barramundi diet

Cost Analysis

Cost of starting fish feed mill projects is affected by many factors, including factory building cost, raw material cost, machinery cost, energy consumption cost, labor cost etc., whether you decide to make
