In the ring die pellet mill, what is the influence of feed moisture?

Nowadays, the cost of feed production is getting higher and higher, and the profit of enterprises tends to be low gradually. Therefore, the cost of feed has become the main factor affecting the profit of feed enterprises. If feed enterprises want to win in the competition, the production cost will be restricted, so in order to reduce the production cost, they must maximize the benefits in terms of production efficiency and machine wear. In addition to management factors and mechanical equipment reasons in feed production, feed moisture is the most critical factor affecting production costs. Scientific use of moisture can reduce production energy consumption, mechanical wear and process loss without reducing feed quality. Thereby, the production efficiency is improved, the production cost is reduced, and at the same time, the normal water content of the feed is maintained, the palatability of the feed can be improved, and the production performance of animals can be improved.

1 Moisture content in feed products and its impact on economic benefits

1.1 In autumn and winter, due to the low temperature, manufacturers mostly use newly-launched corn, etc. These newly-launched raw materials generally have higher moisture content, but because the raw materials are fresh from the factory, the quality of the product is not easy to guarantee, and the production cost is also higher. The moisture content of corn-soybean meal-based rations is generally below 13% after pelleting, which can basically meet the quality control regulations. However, with the large-scale use of agricultural products such as rice bran meal and DDGS, the moisture content of the finished product has dropped to less than 12%. In spring and summer, the moisture content of feed raw materials is generally around 11%-13%. In addition to the high temperature in summer, the moisture content of feed raw materials is partially lost in the process of crushing and pelletizing, making the moisture content of the finished feed very low, generally around 9%-11%. below the standards required by the government. Too low feed moisture will lead to increased dust during feed production, increased loss rate of finished products, increased energy consumption for granulation, unsatisfactory corn gelatinization, wear of granulation ring die, decrease in feed palatability, etc., which will directly affect food quality. social benefits of the enterprise.

1.2 The impact of the moisture content of feed products on the economic benefits of feed manufacturing enterprises The moisture content of feed products not only affects the internal and external business quality of feed, but also has a direct impact on product yield and social benefits. A pellet feed enterprise with an annual output of 30,000 tons can lose as much as 750,000 yuan in economic benefits. Adjusting production technical parameters according to changes in production seasons and raw materials, especially the adjustment of conditioning parameters during granulation, can significantly improve the economic benefits of the enterprise and the quality of feed products.

1.3 The effect of feed water retention on animal production performance Liu Chunxue and others studied the effect of adding 0%, 0.5%, 1.5% and 2.5% water in the mixer powder on the growth performance of pigs. The results showed that adding 0.5% and 1.5% water to the powder, the daily gain of pigs increased by 2% and 9% respectively compared with the control group, and the feed utilization efficiency was also significantly improved. One of the reasons for this is that the degree of gelatinization and granule durability of starch during granulation increases after adding water. Adding 2.5% water did not improve the growth performance of pigs, because adding too much water before conditioning will reduce the ability of the material to absorb steam, thereby reducing the conditioning temperature, which is not conducive to starch gelatinization.
