A new breakthrough in cold granulation technology: low-temperature granulation high-quality teaching tank

1. Disadvantages of Traditional Steam Pelleting iYL China Feed Industry Information Network - based on feed, serving animal husbandry

Traditional pellet processing often relies on steam pelleting, which is promoted as a method to improve the conversion rate through heat treatment. However, in practice, this technique has several significant drawbacks. The temperature used in steam pelleting typically ranges from 70 to 80 degrees Celsius, which is relatively low compared to the 120-degree cooking process already applied to soy meal. As a result, the additional heat from steam pelleting offers little real benefit. Moreover, while steam pelleting can enhance the gelatinization of corn starch, there is no solid experimental evidence proving a direct correlation between this gelatinization and improved conversion efficiency. Therefore, the so-called "ripening" effect is more of a marketing tactic than a scientifically validated advantage. Another major issue with steam pelleting is its negative impact on sensitive ingredients. High-quality feed formulas often include components like whey powder, multi-vitamins, enzymes, probiotics, and small peptides—substances that are highly sensitive to heat. The high temperatures involved in steam pelleting can degrade these active ingredients, reducing their effectiveness and ultimately affecting the performance of the final product. For instance, whey powder may discolor or become harder, making it less desirable for use in premium feeds. Additionally, the secondary granulation process that follows steam pelleting introduces further challenges. Lowering the granulation temperature and extending the cooling time can lead to inconsistent results, and residual steam pressure may still affect the quality of the final pellets.

2. Four Advantages of Cold Granulation Technology iYL China Feed Industry Information Network - based on feed, serving animal husbandry

A newly developed cold granulation technology has been introduced and applied to teaching tanks and suckling pig feed, offering a significant improvement over traditional steam pelleting. This method completely avoids the disadvantages of steam granulation and effectively solves issues related to pellet formation. First, the dry cold forming technology ensures high activity. Unlike steam pelleting, it doesn’t require water or steam, allowing for the production of high-quality whey powder pellets. It also increases processing speed, reduces granulation temperature, and shortens the overall time, preserving the activity of the ingredients. Second, the raw material pretreatment technology is well-established. Through advanced pretreatment methods, the ripening of key proteins is significantly enhanced, surpassing the effects achieved by steam pelleting. Third, the adjustable crispness technology is specifically designed for cold granulation. It allows for customization of the pellet’s texture according to market needs, meeting the high standards required for products with high whey content. This challenge has been successfully overcome. Fourth, the rapid water dissolution technology enables quick solubility. By simulating the puffing process, cold granulation pellets dissolve quickly in water, improving digestibility and absorption, especially for suckling pigs. At room temperature, they fully dissolve within one minute, competing with instant expanded pellets in performance.

3. Application Progress of Cold Granulation Technology iYL China Feed Industry Information Network - based on feed, serving animal husbandry

Our cold granulation technology has been patented and passed the review by the State Intellectual Property Office, entering the public announcement phase. It has already been successfully implemented in various educational and feeding enterprises using core materials such as cold pig granules or the PSS100P suckling pig companion. This innovation represents a major step forward in feed processing, offering both technical and practical advantages.
