Aquaculture is the fastest growing food production sector in the world, all fish for human consumption for about 50% comes from aquaculture. Depending on the fish species and farming methods, feed aquatic feed into floating and sinking feeds.Floating feed is the result of the cooking process and the heat and pressure off the destructive enzymes and more digestible. By advancing along the feed screw extruder barrel at 120-1752 ℃ cooking materials for about 30 seconds. The homogeneous mixture was cooked by high-pressure die forced. The expansion of the material, because of the pressure difference. When manufacturing conditions are not optimal, when the feed produced by extrusion can occur floating feed production. Sinking feed pellets are solid application process submerged. Bottom feeders shrimp, like e.g. pellets sink (density ratio of water 1 g / cm3 or more), we will not accept floating feed. Farmers can not always estimate appeared in his pond biomass appropriate feeding rate and feeding is too low or too high than the actual demand. Formation of aquatic feed.
 
In the production of fish feed, it can be two main ways, granulation or extrusion to manufacture. For the majority of the market is still strongly recommended granulation solution. The following description will proposed.Pulverizer milled granulation process: by a hammer mill feed size reduction process.
 
Mixing system: Second, even if the balance of blend material forward process. Like pre-mixed liquid, other sources of oil, adding now, and mixed with the raw material batch
Granulation: mixer through the feed hopper into the feed screw into the material terms of which the diameter difference regulator and double uniaxial conditioning followed feed down. Indirect and direct steam is added in this step. Retention time can be controlled by a frequency controller. Feed particle size is controlled by the die aperture.
Drying: After evaporation of the dryer front to add extra water.
Cooling: pellets cooler temperatures reduce heat to ambient air temperature of ± 2 ℃.
 
Bagging and sealing system: load cells and the particles making machine bagged and sealed bags save.
