The moisture content of a suckling pig pellet and its impact on the 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

1 The moisture content of the piglet pellets 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

In the winter and spring seasons, due to the lower temperature, feed manufacturers use more newly listed corn, the water content is relatively high, after the feed production granulation, the water content is about 13%, which can basically meet the quality control requirements. However, in summer and autumn, the feed material moisture is 11%~13%, and the temperature is high. The moisture of the feed ingredients is lost in the process of crushing, granulating and pre-treatment, so that the moisture of the finished feed is 9%~11%. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

2 The effect of pellet moisture on the performance of suckling pigs 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

The moisture content of the pellets is too high, the nutrient concentration is low, and it is easy to be mildewed and deteriorated during use; the moisture content of the pellets is too low, which will reduce the gelatinization degree and digestibility of starch, and the hardness of the pellets is large, which affects the palatability of suckling pigs and reduces feed intake. . 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

3 The influence of particulate water on mechanical wear and production efficiency 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

The lower the moisture content of the pellets, the more severe the mechanical wear and the lower the production efficiency. The moisture content of the pellets is 11%~13%, the production efficiency is fast, and the mechanical wear is light. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

4The impact of moisture content of pellets on the economic benefits of enterprises 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

The moisture content of the pellets not only affects the quality of the feed, but also affects the yield and economic benefits of the product. An enterprise with an annual output of 20,000 tons of pellets can have an annual economic benefit of up to 2 million yuan (according to an annual output of 20,000 tons, by adjusting the moisture content, increasing by 2% per t, and the price per ton is 5,000 yuan). According to the different climates in the production season and the change of moisture content of raw materials, adjusting the production process parameters can significantly improve the feed quality and economic benefits of the enterprise. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

Second, the method of improving the moisture content of pellets in the feed processing process 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

1 moisture control in the process of raw material pulverization 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

By comparing and analyzing the results of the production of the pulverizer sieves with different pore sizes, it is found that the moisture loss of the raw materials after pulverization increases significantly as the pulverization particle size of the raw materials decreases. As the moisture content of the raw material increases, the pulverization efficiency also decreases significantly, and the energy consumption also increases. The moisture loss during the raw material pulverization process is generally around 0.5%. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

2 moisture control during feed mixing 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

The moisture loss during the feed mixing process is very small and can be ignored. When the moisture content of the powder after mixing is relatively low, it may be considered to spray atomized water when the materials are mixed. However, there are many problems in adding water to the mixer. It must be highly valued: 1 Water added to the mixer cannot be directly used with tap water, and special treatment or anti-fungal agent is required. 2 It is necessary to configure the nozzles with the appropriate number and size, adjust the position of the nozzles and the water spray rate to ensure uniform water spray. 3 After the end of the production, clean the mixer and the granulation bin to avoid the residue of the inner wall material of the mixer and the granary. 4 Real-time monitoring of moisture and weather changes of raw materials and final products, and determining the amount of water added during mixing according to the monitoring results to ensure that the water content of the final product is within a safe range. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

3 moisture control in the process of quenching and tempering 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

Steam quenching and tempering is the key process in the processing of pellet feed. The quenching and tempering effect directly affects the quality of the pellet and the moisture content of the finished product. Steam quality and quenching and tempering time are two important factors that affect the quenching and tempering effect. In the production process, the steam trap can be adjusted or closed, and low-pressure steam can be used to increase the quenching and tempering time of the material in the conditioner, so that the material and the steam are thoroughly mixed, so that the material can fully absorb the moisture in the steam, thereby increasing the moisture of the product. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

4 choose the right granulation ring mold 9MW China feed industry information network - based on feed, service animal husbandry

The pore size and compression ratio of the granulator ring mold are the main factors affecting the capacity of the granulator, and also one of the factors affecting the moisture content of the pellet feed. The ring die with a small aperture has a small diameter of the particles, and the cooling air volume of the cooler easily penetrates the feed particles, so that the moisture carried away during cooling is high, and the moisture of the feed product is low. On the other hand, the material ring mold with a large pore diameter has a large particle diameter, and the cold air does not easily penetrate the particles, and the moisture carried away during cooling is less, and the moisture of the feed product is increased. For the ring mold with relatively large compression, the friction resistance is large during the granulation process, the material does not easily pass through the pore diameter, and when the granulation is performed, the friction temperature is high, the water dispersion is large, and the moisture of the feed pellet is lowered. Generally, the suckling pig material uses a ring mold with a relatively small pore diameter. Therefore, the use of a ring mold with a low compression ratio is advantageous for improving the quality and moisture content of the pellet material. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry

5 When the pellets are cooled, choose the appropriate cooling air volume. 9MW China Feed Industry Information Network - Based on feed, serving animal husbandry

The purpose of the cooling process is to reduce the temperature of the pellet feed so that it does not exceed 3 °C at room temperature; it can also take away the moisture in the feed, so that the moisture of the feed product meets the specified requirements, and set the cooling parameters of the finished product according to the moisture before cooling of the finished product. To avoid excessive water loss. 9MW China Feed Industry Information Network - based on feed, serving animal husbandry
