one. Disadvantages of traditional steam granulation The conventional method of processing the pellets is steam granulation, and the selling point is ripening to increase the conversion rate. In the actual operation process, there are big problems. The temperature of steam granulation is also 70-80 degrees, which is meaningless for soy meal that has been cooked at 120 degrees. Steam granulation can improve the gelatinization of corn starch, but there is no experimental data to prove its correlation between gelatinization and conversion efficiency. Therefore, this ripening is just a propaganda. The adverse effects of steam granulation are also very large. High-grade teaching materials should add a large proportion of whey powder, multi-dimensional, enzyme preparation, micro-ecology, small peptide and other active ingredients, steam granulation temperature has a great destructive effect on its activity, affecting the feeding effect. For example, whey powder is prone to discoloration and increase in hardness. The secondary granulation process based on this is the steam granulation to the cold granulation direction. The partial granulation temperature is lowered, the quenching time is too long, and the steam pressure is still present, which affects the final granulation effect. two. Cold granulation teaching trough four advantages The newly developed cold granulation core technology is applied to the processing of the teaching tank and the suckling pig granules, which is further than the secondary granulation. The drawbacks of steam granulation can be completely avoided, and the molding problem of the granules can be solved. First, dry cold forming technology has high activity. No need to add water and steam, ensure the formation of high whey powder pellets, increase the processing speed, reduce the granulation temperature, and the granulation time is short, thus ensuring the activity of the grooving particles. Second, the raw material pretreatment technology is ripe. Through the pretreatment technology of raw materials, the ripening of raw materials, especially key proteins, can be greatly improved, which is much higher than the aging of steam granulation. Third, the adjustable technology is crisp and good. The adjustable adjustable technology specially developed for cold granulation can adjust the degree of crispness according to market demand, and meet the high requirements of the granules for the degree of crispness, especially the problem of the crispness of the granules of the high whey powder. Has been successfully conquered. Fourth, rapid water dissolving technology, fast water dissolution. The cold granulation granules processed by the simulated puffing principle can be characterized by rapid water dissolution, which is especially beneficial for the digestion and absorption of suckling pigs. At room temperature, it is completely soluble in water for one minute and can compete with the instant phase of the expanded pellets. three. Cold granulation teaching material application progress Our cold granulation technology has applied for invention patents, passed the review of the State Intellectual Property Office, and entered the publicity period. This technology has been successfully applied to many teaching and feeding enterprises through the cold pig granulated core material or the suckling pig cold granule companion PSS100P.
