How to making Floating fish feed production lines?


Floating fish feed production mainly goes through the following steps: 

Material crushing→material mixing→extruding process→pellets drying→oil spraying process→pellets cooling→pellet packing
1.First the ingredients for making fish feed are ground more finely by the hammer mill, thereby making the feed more digestible.
2. Powdered ingredients are mixed in a certain proportion by fish feed mixer.
Notice that small fish require high protein levels, staring at 40% protein and gradually reducing at 30% protein.
3. The kernel step of feed production is extrusion. There are two types of fish feed machines for extrusion: dry type fish feed machine and wet type fish feed machine. For feed production in Kenya, dry type fish feed extruder is recommended, due to suitable price and stable performance. Many customers cooperated with us are all satisfied with dry type feed machine. Wet type fish feed machine is more suitable for large scale production and people who have higher requirements for feed pellet performance. By extrusion, ingredients are cooked at higher temperature and therefore makes the feed even more digestible.
Note: The size of the pellet should be about 25% the size of the gape of the mouth.
4. Fish feed pellets from pellet making machine need to lower high moisture and temperature. Pellet drying by fish feed dryer is necessary.
5.For acquiring better smell and taste, people often use oil spraying machine to spray oil to the surface of fish feed pellets. Oil spraying step is optional. If you think pellets from extrusion are ok, just ignore it.
6.Hot pellets are soft and easily broken, which can result in a high percentage of fines. By cooling pellets can be harden.The fish feed pellets are packaged in bags for further transporting and storage.
Azeus, the professional fish feed machine manufacturer, offer both the single machine and the complete floating fish feeds line suitable for a wide range of freshwater species such as Tilapia, Catfish and Trout.
