Pellet Hardness Regulation in Feed Pellet Machine

The Impact of Raw Material Formula and Processing Technology

When pelletizing with feed pellet machine, various characteristics of the raw materials affect the hardness of the pellets. The formula and processing technology of the raw materials are key determinants of pellet hardness. Therefore, adjustments should be made according to specific production needs when using feed pellet machine.

The Importance of Raw Material Grinding Size

During the grinding process of raw materials, the grinding size is a decisive factor for pellet hardness. The finer the raw material particles, the easier it is for starch to gelatinize during the conditioning process, resulting in stronger adhesion and less prone to breakage, thus increasing the hardness. A reasonable distribution of grinding particle sizes not only facilitates the pellet formation and appearance quality but also ensures the product has the appropriate hardness and a lower grinding rate.

The Influence of Pre-treatment on Pellet Hardness

Destruction of Anti-nutritional Factors

Pre-treatment of raw materials effectively destroys anti-nutritional factors, kills bacteria, eliminates harmful substances, and induces material denaturation and full starch gelatinization. Gelatinized starch significantly affects pellet hardness. The greater the degree of gelatinization of the pellet material, the higher the hardness.

Methods to Reduce Pellet Hardness

Due to the high degree of gelatinization in the pellet material, the hardness of the pellets also increases. To reduce the hardness of the pellets, other methods must be employed, such as adjusting the raw material formula or optimizing the processing technology.

The Role of Mixing and Water-Mixing Technology

Improving Uniformity and Consistency

Mixing of raw materials improves the uniformity of different particle size components, which helps maintain the consistency of pellet hardness and enhances product quality. Water-mixing technology is very mature in some companies. By adding 1% to 4% moisture in the mixer, the stability and hardness of pellet feed can be improved.

Precautions for Water-Mixing Technology

In the production of pellet feed, water-mixing technology is a crucial step. However, adding water to the mixer of the feed pellet machine requires extreme caution. Adjustments must be made according to factors affecting raw material moisture and weather changes to ensure that the finished product moisture is within a safe range. Additionally, the mixer should be cleaned at the end of each day to prevent spoilage and oxidation of the finished product.

Conclusion

By properly controlling the grinding size, pre-treatment, mixing, and water-mixing processes of raw materials, the hardness of pellets produced by feed pellet machine can be effectively regulated to meet different production needs, improve product quality, and ensure the stability and market competitiveness of the feed.
