Key points of feed pellet machine process optimization

The performance of feed pellet machine in feed production directly impacts the quality and output of feed. However, many feed mills face issues in the arrangement and operation of their feed pellet machine, leading to production that does not meet design specifications and pellet quality issues such as rough surfaces, low hardness, susceptibility to breakage, and high flour content. These problems may be related to the selection and processing methods of raw materials.

The Importance of Raw Material Treatment

Properly conditioned raw materials should have a certain viscosity that aids in pellet formation. For raw materials high in crude fiber, the appropriate addition of lubricants can reduce friction with the ring die, facilitating the smooth passage of materials through the die and enhancing the appearance quality of the pellets. Typically, the addition is controlled around 1% to prevent pellet looseness. If a higher fat content is required, post-granulation spraying can be applied, especially suitable for the production of high-energy feeds.

Pellet Size and Production Efficiency

Pellet size directly affects the surface area of the feed, influencing the rate at which moisture is absorbed from steam. Smaller pellet sizes mean a larger surface area, which helps to improve the efficiency of steam utilization. However, from the perspective of feed pellet machine efficiency, the finer the raw material is ground, the higher the pellet strength, but this also requires more steam. Improper control can lead to machine blockages. Moreover, over-refining raw materials increases energy consumption.

The Importance of Screen Selection

To address pellet size issues, it is essential to select screens with the appropriate mesh size. Using screens with larger apertures, such as 2.5~3.0mm, can prevent problems associated with overly fine particles while ensuring the required granulation for feed conditioning, which helps to reduce the flour content in grains and thus improve the overall quality of the feed.

The Importance of Uniform Mixing

Attention must also be paid to the uniformity of raw material mixing before granulation. Due to the complexity of feed formulations and the significant differences in the specific gravity of various raw materials, it is necessary to ensure thorough mixing during the process to guarantee balanced nutrition and stable quality of the feed.

Conclusion: Directions for the Optimization of feed pellet machine Processes

By carefully selecting and treating raw materials, adjusting pellet size appropriately, choosing the right screen aperture, and ensuring uniform mixing, the output and quality of feed pellet machine in feed mills can be effectively improved. These measures help address existing problems, meet design requirements, and enhance the commercial value and market competitiveness of feed.
