Poultry Feed Pellet Making Machine , Manure / Fertilizer Pellet Machine

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.

Features

1. Gear directly-connecting driving is adopted for high efficiency;
2. The bearing and oil seal in the main drive are imported,resulting in long service life and low equipment noise;
3. Feeder, conditioner and chute are made of stainless steel for long service life;
4. Feeder is variable speed controlled to meet different output requirements;
5. The conditioner is longer and thicker, built-in steam set could make steam condition cooking material fully, ensure the high quality of the feed;
6. It is with magnet and over load protection system, which can protect machine well during production;
7. New style S-shape spring coupling is adopted to obtain big offset travel and further smooth running;
8. It can be fitted multi-layer jacket condition or double differential conditioner so as to meet the different requirements of producing high quality shrimp feed;
9. The special technique dies and shrimp feed knives make that the cropping is more uniform and the cut is flatter.
