Pelletizing Process of Feed Pelletizer:
1. Conditioning: Conditioning is the most important link in the granulation
process. The quality of conditioning directly determines the
quality of pellet feed. The purpose of conditioning is to temper
the mixed dry powder into a powdered feed with a certain moisture
and humidity that is conducive to pelleting. At present, feed mills
in my country complete the conditioning process by adding steam.
2. Granulation: (1) Ring die granulation: the quenched and tempered materials are
firstly removed by the security magnet, and then evenly distributed
between the pressing and mixing and pressing dies, so that the
materials enter the extrusion from the pressing area of the
feeding area. It is continuously extruded and divided by the
pressing roller into the die hole to form a columnar feed. As the
die rotates, it is cut into granular feed by a cutter fixed outside
the die. (2) The material after the flat die granulation and mixing
enters the granulation system, and the rotary distributor located
at the upper part of the granulation system evenly spreads the
material on the surface of the die, and then presses the material
into the die hole by the rotating press and mixes it. The bottom is
pressed out, and the rod-shaped feed out of the die hole is cut
into the required length by the cutting roller.
3. Cooling During the granulation process, due to the introduction of
high-temperature and high-humidity steam, a large amount of heat is
generated by the extrusion of the material, so that when the pellet
feed just comes out of the granulator, the water content reaches
16%-18% and the temperature is as high as 75C-85C Under this
condition, the pellet feed is easily deformed and broken, and the
phenomenon of sticking and mildew will also occur during storage.
The moisture must be reduced to below 14%, and the temperature must
be reduced to below 8 C higher than the air temperature, which
requires cooling.
4. Crushing In the production process of the pellet mill, in order to save
electricity, increase output and improve quality, the material is
often first made into pellets of a certain size, and then crushed
into qualified pellets with a crusher according to the particle
size of livestock and poultry feeding. product.
5. Screening: After the pellet feed is processed by the crushing process, some
unqualified materials such as powder agglomerates will be produced.
Therefore, the crushed pellet feed needs to be screened into
products with neat particles and uniform size.
