Small Fish Feed Pellet Machine
Small Fish Feed Pellet Production Line Applications
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 pellets and the submerged fish feed.
Process Of Small Fish Feed Pellet Production Line:
1. Material Crushing→Mixing→Conveying→
Pellet Extruding→Drying→Cooling→Blending
2. 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. Drying And Cooling
After the extruding, the pellets need drying to remove excess water. This will ensure the fish feed pellets will not be moldy deterioration. The function of the cooler can also remove the excess moisture when lower the temperature. After cooling, the pellets temp is equal to room temp, the moisture will be 12%-13% and becomes hard. It’s not easy to destroy and mildew.
Pellet Extruding Working Principle
The extrude 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.
