Corn is familiar to all of us and it is one of the main raw material sources of feed. In general, corn contains 70 to 75% of starch, and this composition is actually not conducive to animal digestion and absorption. Therefore, in order to improve the palatability and effectively increase the feed intake of livestock and poultry animals, an appropriate amount of puffed corn can be added to the feed. Extruded corn breaks the crystal structure of corn starch through high-temperature, high-pressure and high-shear force of the extrusion process, and expands and gelatinizes the starch granules. The expanded corn has the characteristics of strong aroma, easier digestion and absorption, and the like. It is very suitable for improving the quality of feed. In the quality control management of puffed corn, volume weight is the focus of quality control, and we can use the grain container to measure.
The bulk density of grain is closely related to the quality of grains such as corn and rice, and it is one of the important indicators of grain quality. Therefore, in the quality control management of extruded corn, the determination of the bulk density of corn raw materials is also one of the key testing items. To produce high-quality, good-quality extruded corn, it is necessary to use high-quality corn raw materials. For example, the pig material company uses high quality corn in the northeast and Xinjiang corn as raw materials (requires moisture ≤14%, impurity ≤ 1%, mildew ≤ 1%, bulk density ≥700g/L, vomiting toxin ≤1000 ppb, etc.), low toxin content The stability of the production area is conducive to the stability of the expansion process. Therefore, the application of grain container weight in the management of puffed corn quality control can help to better control the quality of raw materials and improve the production quality and application value of expanded corn.
With the grain weight receptor acting on the grain quality testing end, the bulk density testing of corn raw materials will be more accurate and effective. On the one hand, it can effectively screen the used corn raw materials and improve the quality of corn raw materials; on the other hand, it uses high quality corn. The production of expanded corn from raw materials can also guarantee the quality of expanded corn, greatly improve the quality of livestock and poultry feed, and create greater positive value for processing enterprises.
