Feed pellet machine is also named as pellet feed mill, fodder pellet mill. It belongs to animal feed processing equipment, which can directly extrude corn, soybean meal, rice husk, straw and grass into small pellets.

If it is a pellet production line with the same output, for example, the pellet production line that is also 1t / h, the feed pellet production line with feed pellet granulator has a lower investment cost than the wood pellet production line.

Richi machinery produces a variety of animal feed pellet machines and wood pellet machines. If you need a large amount of pellets, you need to set up a pellet production line. We can provide you with a complete solution from the early design to the later equipment installation and training.

Affect of ingredient particle size and grinding on pellet quality

The second factor influencing feed pellet line quality is the feed ingredient particle size. Although doubted by some researchers, it is accepted that decreasing ingredient particle size has a good influence on pellet quality. However, over grinding is not recommended to avoid power wastage, reduced production rate and suboptimal gizzard development. On the other hand, coarse grinding eases pellet break down and decreases starch gelatinisation (high degree of gelatinisation is required to produce good pellets).

The cooler should be taken into consideration.

After leaving the pellet mill, the temperature of the pellets ranges from 70-90° C and the moisture from 15-17%. Proper cooling (via a stream air cooling machine) is required to lower pellet temperature to about 8° C above the ambient temperature, and moisture % to be 12%. The cooling machine can be either a horizontal or vertical type. Quick cooling leads to removal of more moisture and heat from the surface of the pellets than their core, and the resultant pellets will be brittle. On the other hand, prolonged cooling produces very dry pellets that can be exposed to abrasion and can be of low palatability.

Conclusion

Pellet quality can be influenced by several factors, including the ingredients, diet formulation and processing. A good rule of thumb is the pellet quality factor (PQF), that each feed ingredient has. The PQF has a score from 0 to 10, where 0 predicts poor pellet quality and 10 good pellet quality. From experience we know that starch and its gelatinisation is the most important factor for achieving the desired pellet quality. However, recent reports indicated that the positive impact of protein on pellet quality is much more important than that of starch.
