Small Fish Feed Pellet Production Line Applications

1. This small fish feed pellet production line production line can produce the feed pellets for frewarter fish,marine fish. It can also produce floating fish feed pelles and the submerged fish feed.
Material Of Small Fish Feed Pellet Production Line
There are 4 kinds of materials for the fish feed pellet, they are:
 1.1Protein Material
Cardamom om,cotton kernel,rapeseed meal,fish meal, blood bone meal.
1.2Energy material
Maize, porcelain powder,
1.3 Oil raw material
Fish oil, soybean oil, rapeseed oil.
1.4Premix Material
Some mineral,vitamin

2. Process Of Small Fish Feed Pellet Production Line

Material Crushing→Mixing→Conveying→Fish Feed Pellet Machine→Drying→Cooling→Blending

3.1 Material Crushing
The fish feed pelletizing require the raw material size less than 6mm, so protein or energy material need crushing before the pelletizing process. Below is the crusher in this small fish feed pellet line.
3.2Material Mixing
In order to ensure the pellets has uniform nutrition, it need to mix all the raw materials before the extrauding process. The Screw conveyor  connects crusher and mixer. This is process is very important to the finished pellet quality.
3.Pellet Extrauding

4.  Working Principle

The extruder has a pair of screws and sleeves that have the function of mixing and twisting. After the raw material enters the expansion chamber, the material is squeezed, rubbed, sheared, etc. between the screw sleeves, and the internal pressure is continuously increased, up to 4Mpa, and the temperature is continuously rising, up to 140 degrees Celsius.
During the period of 3-7s, the temperature and pressure increase sharply, and the structure of the material changes, which further gelatinizes the starch, denatures the protein, destroys the crude fiber, and kills harmful bacteria such as Salmonella. The high temperature and high pressure materials come out from the discharge port, and the pressure is suddenly released in an instant, and the water is partially flashed.
After cooling, the material is loose and porous, and the expanded material is in the form of agglomerates, flocs or coarse chips.

Fish Farmers In Nigeria Can Produce Fish Feeds Themselves

  Nigeria is one of the leading producers of catfish in Africa. But this has been grossly inadequate to meet WHO’s protein requirement recommendation per person. This is made up for by imports from Europe, South America and the Far East. That is unnecessary while using the Minister of agriculture’s assertion that Nigeria’s aquaculture industry has potential to produce 4 million metric tons of fish which can serve the whole of Africa.   With our fish feed machine , even those who are just trotting in aquaculture business can afford to make fish feeds themselves using available materials in Nigeria. One of the challenges of fish farmers is feed in Nigeria and 80 percent of the cost of fish farming is the feed. Although the quality of the imported fish feeds is good, the cost puts them out of reach for most farmers. If you produce fish feed by yourself, cost of production will drop by 54 per cent because you don’t need to pay for labor, just carry it and feed the fish and you will be usin
